+# Original listfile by Christian Ehrlicher <Ch.Ehrlicher at gmx.de>
+# Refined and expanded by Daniel Richard G. <skunk at iSKUNK.ORG>
+# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered
+# 2007-09-19 Adjusted by PH to retain previous default settings
+# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
+#            (b) Ensure pcretest and pcregrep link with the local library,
+#                not a previously-installed one.
+#            (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
+#                PCRE_SUPPORT_LIBBZ2.
+# 2008-01-20 Brought up to date to include several new features by Christian
+#            Ehrlicher.
+# 2008-01-22 Sheri added options for backward compatibility of library names
+#            when building with minGW:
+#            if "ON", NON_STANDARD_LIB_PREFIX causes shared libraries to
+#            be built without "lib" as prefix. (The libraries will be named
+#            pcre.dll, pcreposix.dll and pcrecpp.dll).
+#            if "ON", NON_STANDARD_LIB_SUFFIX causes shared libraries to
+#            be built with suffix of "-0.dll". (The libraries will be named
+#            libpcre-0.dll, libpcreposix-0.dll and libpcrecpp-0.dll - same names
+#            built by default with Configure and Make.
+# 2008-01-23 PH removed the automatic build of pcredemo.
+# 2008-04-22 PH modified READLINE support so it finds NCURSES when needed.
+# 2008-07-03 PH updated for revised UCP property support (change of files)
+# 2009-03-23 PH applied Steven Van Ingelgem's patch to change the name
+#            CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE
+#            is included within another project.
+# 2009-03-23 PH applied a modified version of Steven Van Ingelgem's patches to
+#            add options to stop the building of pcregrep and the tests, and
+#            to disable the final configuration report.
+# 2009-04-11 PH applied Christian Ehrlicher's patch to show compiler flags that
+#            are set by specifying a release type.

 ChangeLog for PCRE
 ------------------
 
+Version 7.9 11-Apr-09
+---------------------
+
+1.  When building with support for bzlib/zlib (pcregrep) and/or readline
+    (pcretest), all targets were linked against these libraries. This included
+    libpcre, libpcreposix, and libpcrecpp, even though they do not use these
+    libraries. This caused unwanted dependencies to be created. This problem
+    has been fixed, and now only pcregrep is linked with bzlib/zlib and only
+    pcretest is linked with readline.
+
+2.  The "typedef int BOOL" in pcre_internal.h that was included inside the
+    "#ifndef FALSE" condition by an earlier change (probably 7.8/18) has been
+    moved outside it again, because FALSE and TRUE are already defined in AIX,
+    but BOOL is not.
+
+3.  The pcre_config() function was treating the PCRE_MATCH_LIMIT and
+    PCRE_MATCH_LIMIT_RECURSION values as ints, when they should be long ints.
+
+4.  The pcregrep documentation said spaces were inserted as well as colons (or
+    hyphens) following file names and line numbers when outputting matching
+    lines. This is not true; no spaces are inserted. I have also clarified the
+    wording for the --colour (or --color) option.
+
+5.  In pcregrep, when --colour was used with -o, the list of matching strings
+    was not coloured; this is different to GNU grep, so I have changed it to be
+    the same.
+
+6.  When --colo(u)r was used in pcregrep, only the first matching substring in
+    each matching line was coloured. Now it goes on to look for further matches
+    of any of the test patterns, which is the same behaviour as GNU grep.
+
+7.  A pattern that could match an empty string could cause pcregrep to loop; it
+    doesn't make sense to accept an empty string match in pcregrep, so I have
+    locked it out (using PCRE's PCRE_NOTEMPTY option). By experiment, this
+    seems to be how GNU grep behaves.
+
+8.  The pattern (?(?=.*b)b|^) was incorrectly compiled as "match must be at
+    start or after a newline", because the conditional assertion was not being
+    correctly handled. The rule now is that both the assertion and what follows
+    in the first alternative must satisfy the test.
+
+9.  If auto-callout was enabled in a pattern with a conditional group whose
+    condition was an assertion, PCRE could crash during matching, both with
+    pcre_exec() and pcre_dfa_exec().
+
+10. The PCRE_DOLLAR_ENDONLY option was not working when pcre_dfa_exec() was
+    used for matching.
+
+11. Unicode property support in character classes was not working for
+    characters (bytes) greater than 127 when not in UTF-8 mode.
+
+12. Added the -M command line option to pcretest.
+
+14. Added the non-standard REG_NOTEMPTY option to the POSIX interface.
+
+15. Added the PCRE_NO_START_OPTIMIZE match-time option.
+
+16. Added comments and documentation about mis-use of no_arg in the C++
+    wrapper.
+
+17. Implemented support for UTF-8 encoding in EBCDIC environments, a patch
+    from Martin Jerabek that uses macro names for all relevant character and
+    string constants.
+
+18. Added to pcre_internal.h two configuration checks: (a) If both EBCDIC and
+    SUPPORT_UTF8 are set, give an error; (b) If SUPPORT_UCP is set without
+    SUPPORT_UTF8, define SUPPORT_UTF8. The "configure" script handles both of
+    these, but not everybody uses configure.
+
+19. A conditional group that had only one branch was not being correctly
+    recognized as an item that could match an empty string. This meant that an
+    enclosing group might also not be so recognized, causing infinite looping
+    (and probably a segfault) for patterns such as ^"((?(?=[a])[^"])|b)*"$
+    with the subject "ab", where knowledge that the repeated group can match
+    nothing is needed in order to break the loop.
+
+20. If a pattern that was compiled with callouts was matched using pcre_dfa_
+    exec(), but without supplying a callout function, matching went wrong.
+
+21. If PCRE_ERROR_MATCHLIMIT occurred during a recursion, there was a memory
+    leak if the size of the offset vector was greater than 30. When the vector
+    is smaller, the saved offsets during recursion go onto a local stack
+    vector, but for larger vectors malloc() is used. It was failing to free
+    when the recursion yielded PCRE_ERROR_MATCH_LIMIT (or any other "abnormal"
+    error, in fact).
+
+22. There was a missing #ifdef SUPPORT_UTF8 round one of the variables in the
+    heapframe that is used only when UTF-8 support is enabled. This caused no
+    problem, but was untidy.
+
+23. Steven Van Ingelgem's patch to CMakeLists.txt to change the name
+    CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE is
+    included within another project.
+
+24. Steven Van Ingelgem's patches to add more options to the CMake support,
+    slightly modified by me:
+
+      (a) PCRE_BUILD_TESTS can be set OFF not to build the tests, including
+          not building pcregrep.
+
+      (b) PCRE_BUILD_PCREGREP can be see OFF not to build pcregrep, but only
+          if PCRE_BUILD_TESTS is also set OFF, because the tests use pcregrep.
+
+25. Forward references, both numeric and by name, in patterns that made use of
+    duplicate group numbers, could behave incorrectly or give incorrect errors,
+    because when scanning forward to find the reference group, PCRE was not
+    taking into account the duplicate group numbers. A pattern such as
+    ^X(?3)(a)(?|(b)|(q))(Y) is an example.
+
+26. Changed a few more instances of "const unsigned char *" to USPTR, making
+    the feature of a custom pointer more persuasive (as requested by a user).
+
+27. Wrapped the definitions of fileno and isatty for Windows, which appear in
+    pcretest.c, inside #ifndefs, because it seems they are sometimes already
+    pre-defined.
+
+28. Added support for (*UTF8) at the start of a pattern.
+
+29. Arrange for flags added by the "release type" setting in CMake to be shown
+    in the configuration summary.
+
+
+Version 7.8 05-Sep-08
+---------------------
+
+1.  Replaced UCP searching code with optimized version as implemented for Ad
+    Muncher (http://www.admuncher.com/) by Peter Kankowski. This uses a two-
+    stage table and inline lookup instead of a function, giving speed ups of 2
+    to 5 times on some simple patterns that I tested. Permission was given to
+    distribute the MultiStage2.py script that generates the tables (it's not in
+    the tarball, but is in the Subversion repository).
+
+2.  Updated the Unicode datatables to Unicode 5.1.0. This adds yet more
+    scripts.
+
+3.  Change 12 for 7.7 introduced a bug in pcre_study() when a pattern contained
+    a group with a zero qualifier. The result of the study could be incorrect,
+    or the function might crash, depending on the pattern.
+
+4.  Caseless matching was not working for non-ASCII characters in back
+    references. For example, /(\x{de})\1/8i was not matching \x{de}\x{fe}.
+    It now works when Unicode Property Support is available.
+
+5.  In pcretest, an escape such as \x{de} in the data was always generating
+    a UTF-8 string, even in non-UTF-8 mode. Now it generates a single byte in
+    non-UTF-8 mode. If the value is greater than 255, it gives a warning about
+    truncation.
+
+6.  Minor bugfix in pcrecpp.cc (change "" == ... to NULL == ...).
+
+7.  Added two (int) casts to pcregrep when printing the difference of two
+    pointers, in case they are 64-bit values.
+
+8.  Added comments about Mac OS X stack usage to the pcrestack man page and to
+    test 2 if it fails.
+
+9.  Added PCRE_CALL_CONVENTION just before the names of all exported functions,
+    and a #define of that name to empty if it is not externally set. This is to
+    allow users of MSVC to set it if necessary.
+
+10. The PCRE_EXP_DEFN macro which precedes exported functions was missing from
+    the convenience functions in the pcre_get.c source file.
+
+11. An option change at the start of a pattern that had top-level alternatives
+    could cause overwriting and/or a crash. This command provoked a crash in
+    some environments:
+
+      printf "/(?i)[\xc3\xa9\xc3\xbd]|[\xc3\xa9\xc3\xbdA]/8\n" | pcretest
+
+    This potential security problem was recorded as CVE-2008-2371.
+
+12. For a pattern where the match had to start at the beginning or immediately
+    after a newline (e.g /.*anything/ without the DOTALL flag), pcre_exec() and
+    pcre_dfa_exec() could read past the end of the passed subject if there was
+    no match. To help with detecting such bugs (e.g. with valgrind), I modified
+    pcretest so that it places the subject at the end of its malloc-ed buffer.
+
+13. The change to pcretest in 12 above threw up a couple more cases when pcre_
+    exec() might read past the end of the data buffer in UTF-8 mode.
+
+14. A similar bug to 7.3/2 existed when the PCRE_FIRSTLINE option was set and
+    the data contained the byte 0x85 as part of a UTF-8 character within its
+    first line. This applied both to normal and DFA matching.
+
+15. Lazy qualifiers were not working in some cases in UTF-8 mode. For example,
+    /^[^d]*?$/8 failed to match "abc".
+
+16. Added a missing copyright notice to pcrecpp_internal.h.
+
+17. Make it more clear in the documentation that values returned from
+    pcre_exec() in ovector are byte offsets, not character counts.
+
+18. Tidied a few places to stop certain compilers from issuing warnings.
+
+19. Updated the Virtual Pascal + BCC files to compile the latest v7.7, as
+    supplied by Stefan Weber. I made a further small update for 7.8 because
+    there is a change of source arrangements: the pcre_searchfuncs.c module is
+    replaced by pcre_ucd.c.
+
+
+Version 7.7 07-May-08
+---------------------
+
+1.  Applied Craig's patch to sort out a long long problem: "If we can't convert
+    a string to a long long, pretend we don't even have a long long." This is
+    done by checking for the strtoq, strtoll, and _strtoi64 functions.
+
+2.  Applied Craig's patch to pcrecpp.cc to restore ABI compatibility with
+    pre-7.6 versions, which defined a global no_arg variable instead of putting
+    it in the RE class. (See also #8 below.)
+
+3.  Remove a line of dead code, identified by coverity and reported by Nuno
+    Lopes.
+
+4.  Fixed two related pcregrep bugs involving -r with --include or --exclude:
+
+    (1) The include/exclude patterns were being applied to the whole pathnames
+        of files, instead of just to the final components.
+
+    (2) If there was more than one level of directory, the subdirectories were
+        skipped unless they satisfied the include/exclude conditions. This is
+        inconsistent with GNU grep (and could even be seen as contrary to the
+        pcregrep specification - which I improved to make it absolutely clear).
+        The action now is always to scan all levels of directory, and just
+        apply the include/exclude patterns to regular files.
+
+5.  Added the --include_dir and --exclude_dir patterns to pcregrep, and used
+    --exclude_dir in the tests to avoid scanning .svn directories.
+
+6.  Applied Craig's patch to the QuoteMeta function so that it escapes the
+    NUL character as backslash + 0 rather than backslash + NUL, because PCRE
+    doesn't support NULs in patterns.
+
+7.  Added some missing "const"s to declarations of static tables in
+    pcre_compile.c and pcre_dfa_exec.c.
+
+8.  Applied Craig's patch to pcrecpp.cc to fix a problem in OS X that was
+    caused by fix #2  above. (Subsequently also a second patch to fix the
+    first patch. And a third patch - this was a messy problem.)
+
+9.  Applied Craig's patch to remove the use of push_back().
+
+10. Applied Alan Lehotsky's patch to add REG_STARTEND support to the POSIX
+    matching function regexec().
+
+11. Added support for the Oniguruma syntax \g<name>, \g<n>, \g'name', \g'n',
+    which, however, unlike Perl's \g{...}, are subroutine calls, not back
+    references. PCRE supports relative numbers with this syntax (I don't think
+    Oniguruma does).
+
+12. Previously, a group with a zero repeat such as (...){0} was completely
+    omitted from the compiled regex. However, this means that if the group
+    was called as a subroutine from elsewhere in the pattern, things went wrong
+    (an internal error was given). Such groups are now left in the compiled
+    pattern, with a new opcode that causes them to be skipped at execution
+    time.
+
+13. Added the PCRE_JAVASCRIPT_COMPAT option. This makes the following changes
+    to the way PCRE behaves:
+
+    (a) A lone ] character is dis-allowed (Perl treats it as data).
+
+    (b) A back reference to an unmatched subpattern matches an empty string
+        (Perl fails the current match path).
+
+    (c) A data ] in a character class must be notated as \] because if the
+        first data character in a class is ], it defines an empty class. (In
+        Perl it is not possible to have an empty class.) The empty class []
+        never matches; it forces failure and is equivalent to (*FAIL) or (?!).
+        The negative empty class [^] matches any one character, independently
+        of the DOTALL setting.
+
+14. A pattern such as /(?2)[]a()b](abc)/ which had a forward reference to a
+    non-existent subpattern following a character class starting with ']' and
+    containing () gave an internal compiling error instead of "reference to
+    non-existent subpattern". Fortunately, when the pattern did exist, the
+    compiled code was correct. (When scanning forwards to check for the
+    existencd of the subpattern, it was treating the data ']' as terminating
+    the class, so got the count wrong. When actually compiling, the reference
+    was subsequently set up correctly.)
+
+15. The "always fail" assertion (?!) is optimzed to (*FAIL) by pcre_compile;
+    it was being rejected as not supported by pcre_dfa_exec(), even though
+    other assertions are supported. I have made pcre_dfa_exec() support
+    (*FAIL).
+
+16. The implementation of 13c above involved the invention of a new opcode,
+    OP_ALLANY, which is like OP_ANY but doesn't check the /s flag. Since /s
+    cannot be changed at match time, I realized I could make a small
+    improvement to matching performance by compiling OP_ALLANY instead of
+    OP_ANY for "." when DOTALL was set, and then removing the runtime tests
+    on the OP_ANY path.
+
+17. Compiling pcretest on Windows with readline support failed without the
+    following two fixes: (1) Make the unistd.h include conditional on
+    HAVE_UNISTD_H; (2) #define isatty and fileno as _isatty and _fileno.
+
+18. Changed CMakeLists.txt and cmake/FindReadline.cmake to arrange for the
+    ncurses library to be included for pcretest when ReadLine support is
+    requested, but also to allow for it to be overridden. This patch came from
+    Daniel Bergström.
+
+19. There was a typo in the file ucpinternal.h where f0_rangeflag was defined
+    as 0x00f00000 instead of 0x00800000. Luckily, this would not have caused
+    any errors with the current Unicode tables. Thanks to Peter Kankowski for
+    spotting this.
+
+
+Version 7.6 28-Jan-08
+---------------------
+
+1.  A character class containing a very large number of characters with
+    codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer
+    overflow.
+
+2.  Patch to cut out the "long long" test in pcrecpp_unittest when
+    HAVE_LONG_LONG is not defined.
+
+3.  Applied Christian Ehrlicher's patch to update the CMake build files to
+    bring them up to date and include new features. This patch includes:
+
+    - Fixed PH's badly added libz and libbz2 support.
+    - Fixed a problem with static linking.
+    - Added pcredemo. [But later removed - see 7 below.]
+    - Fixed dftables problem and added an option.
+    - Added a number of HAVE_XXX tests, including HAVE_WINDOWS_H and
+        HAVE_LONG_LONG.
+    - Added readline support for pcretest.
+    - Added an listing of the option settings after cmake has run.
+
+4.  A user submitted a patch to Makefile that makes it easy to create
+    "pcre.dll" under mingw when using Configure/Make. I added stuff to
+    Makefile.am that cause it to include this special target, without
+    affecting anything else. Note that the same mingw target plus all
+    the other distribution libraries and programs are now supported
+    when configuring with CMake (see 6 below) instead of with
+    Configure/Make.
+
+5.  Applied Craig's patch that moves no_arg into the RE class in the C++ code.
+    This is an attempt to solve the reported problem "pcrecpp::no_arg is not
+    exported in the Windows port". It has not yet been confirmed that the patch
+    solves the problem, but it does no harm.
+
+6.  Applied Sheri's patch to CMakeLists.txt to add NON_STANDARD_LIB_PREFIX and
+    NON_STANDARD_LIB_SUFFIX for dll names built with mingw when configured
+    with CMake, and also correct the comment about stack recursion.
+
+7.  Remove the automatic building of pcredemo from the ./configure system and
+    from CMakeLists.txt. The whole idea of pcredemo.c is that it is an example
+    of a program that users should build themselves after PCRE is installed, so
+    building it automatically is not really right. What is more, it gave
+    trouble in some build environments.
+
+8.  Further tidies to CMakeLists.txt from Sheri and Christian.
+
+
+Version 7.5 10-Jan-08
+---------------------
+
+1.  Applied a patch from Craig: "This patch makes it possible to 'ignore'
+    values in parens when parsing an RE using the C++ wrapper."
+
+2.  Negative specials like \S did not work in character classes in UTF-8 mode.
+    Characters greater than 255 were excluded from the class instead of being
+    included.
+
+3.  The same bug as (2) above applied to negated POSIX classes such as
+    [:^space:].
+
+4.  PCRECPP_STATIC was referenced in pcrecpp_internal.h, but nowhere was it
+    defined or documented. It seems to have been a typo for PCRE_STATIC, so
+    I have changed it.
+
+5.  The construct (?&) was not diagnosed as a syntax error (it referenced the
+    first named subpattern) and a construct such as (?&a) would reference the
+    first named subpattern whose name started with "a" (in other words, the
+    length check was missing). Both these problems are fixed. "Subpattern name
+    expected" is now given for (?&) (a zero-length name), and this patch also
+    makes it give the same error for \k'' (previously it complained that that
+    was a reference to a non-existent subpattern).
+
+6.  The erroneous patterns (?+-a) and (?-+a) give different error messages;
+    this is right because (?- can be followed by option settings as well as by
+    digits. I have, however, made the messages clearer.
+
+7.  Patterns such as (?(1)a|b) (a pattern that contains fewer subpatterns
+    than the number used in the conditional) now cause a compile-time error.
+    This is actually not compatible with Perl, which accepts such patterns, but
+    treats the conditional as always being FALSE (as PCRE used to), but it
+    seems to me that giving a diagnostic is better.
+
+8.  Change "alphameric" to the more common word "alphanumeric" in comments
+    and messages.
+
+9.  Fix two occurrences of "backslash" in comments that should have been
+    "backspace".
+
+10. Remove two redundant lines of code that can never be obeyed (their function
+    was moved elsewhere).
+
+11. The program that makes PCRE's Unicode character property table had a bug
+    which caused it to generate incorrect table entries for sequences of
+    characters that have the same character type, but are in different scripts.
+    It amalgamated them into a single range, with the script of the first of
+    them. In other words, some characters were in the wrong script. There were
+    thirteen such cases, affecting characters in the following ranges:
+
+      U+002b0 - U+002c1
+      U+0060c - U+0060d
+      U+0061e - U+00612
+      U+0064b - U+0065e
+      U+0074d - U+0076d
+      U+01800 - U+01805
+      U+01d00 - U+01d77
+      U+01d9b - U+01dbf
+      U+0200b - U+0200f
+      U+030fc - U+030fe
+      U+03260 - U+0327f
+      U+0fb46 - U+0fbb1
+      U+10450 - U+1049d
+
+12. The -o option (show only the matching part of a line) for pcregrep was not
+    compatible with GNU grep in that, if there was more than one match in a
+    line, it showed only the first of them. It now behaves in the same way as
+    GNU grep.
+
+13. If the -o and -v options were combined for pcregrep, it printed a blank
+    line for every non-matching line. GNU grep prints nothing, and pcregrep now
+    does the same. The return code can be used to tell if there were any
+    non-matching lines.
+
+14. Added --file-offsets and --line-offsets to pcregrep.
+
+15. The pattern (?=something)(?R) was not being diagnosed as a potentially
+    infinitely looping recursion. The bug was that positive lookaheads were not
+    being skipped when checking for a possible empty match (negative lookaheads
+    and both kinds of lookbehind were skipped).
+
+16. Fixed two typos in the Windows-only code in pcregrep.c, and moved the
+    inclusion of <windows.h> to before rather than after the definition of
+    INVALID_FILE_ATTRIBUTES (patch from David Byron).
+
+17. Specifying a possessive quantifier with a specific limit for a Unicode
+    character property caused pcre_compile() to compile bad code, which led at
+    runtime to PCRE_ERROR_INTERNAL (-14). Examples of patterns that caused this
+    are: /\p{Zl}{2,3}+/8 and /\p{Cc}{2}+/8. It was the possessive "+" that
+    caused the error; without that there was no problem.
+
+18. Added --enable-pcregrep-libz and --enable-pcregrep-libbz2.
+
+19. Added --enable-pcretest-libreadline.
+
+20. In pcrecpp.cc, the variable 'count' was incremented twice in
+    RE::GlobalReplace(). As a result, the number of replacements returned was
+    double what it should be. I removed one of the increments, but Craig sent a
+    later patch that removed the other one (the right fix) and added unit tests
+    that check the return values (which was not done before).
+
+21. Several CMake things:
+
+    (1) Arranged that, when cmake is used on Unix, the libraries end up with
+        the names libpcre and libpcreposix, not just pcre and pcreposix.
+
+    (2) The above change means that pcretest and pcregrep are now correctly
+        linked with the newly-built libraries, not previously installed ones.
+
+    (3) Added PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, PCRE_SUPPORT_LIBBZ2.
+
+22. In UTF-8 mode, with newline set to "any", a pattern such as .*a.*=.b.*
+    crashed when matching a string such as a\x{2029}b (note that \x{2029} is a
+    UTF-8 newline character). The key issue is that the pattern starts .*;
+    this means that the match must be either at the beginning, or after a
+    newline. The bug was in the code for advancing after a failed match and
+    checking that the new position followed a newline. It was not taking
+    account of UTF-8 characters correctly.
+
+23. PCRE was behaving differently from Perl in the way it recognized POSIX
+    character classes. PCRE was not treating the sequence [:...:] as a
+    character class unless the ... were all letters. Perl, however, seems to
+    allow any characters between [: and :], though of course it rejects as
+    unknown any "names" that contain non-letters, because all the known class
+    names consist only of letters. Thus, Perl gives an error for [[:1234:]],
+    for example, whereas PCRE did not - it did not recognize a POSIX character
+    class. This seemed a bit dangerous, so the code has been changed to be
+    closer to Perl. The behaviour is not identical to Perl, because PCRE will
+    diagnose an unknown class for, for example, [[:l\ower:]] where Perl will
+    treat it as [[:lower:]]. However, PCRE does now give "unknown" errors where
+    Perl does, and where it didn't before.
+
+24. Rewrite so as to remove the single use of %n from pcregrep because in some
+    Windows environments %n is disabled by default.
+
+
+Version 7.4 21-Sep-07
+---------------------
+
+1.  Change 7.3/28 was implemented for classes by looking at the bitmap. This
+    means that a class such as [\s] counted as "explicit reference to CR or
+    LF". That isn't really right - the whole point of the change was to try to
+    help when there was an actual mention of one of the two characters. So now
+    the change happens only if \r or \n (or a literal CR or LF) character is
+    encountered.
+
+2.  The 32-bit options word was also used for 6 internal flags, but the numbers
+    of both had grown to the point where there were only 3 bits left.
+    Fortunately, there was spare space in the data structure, and so I have
+    moved the internal flags into a new 16-bit field to free up more option
+    bits.
+
+3.  The appearance of (?J) at the start of a pattern set the DUPNAMES option,
+    but did not set the internal JCHANGED flag - either of these is enough to
+    control the way the "get" function works - but the PCRE_INFO_JCHANGED
+    facility is supposed to tell if (?J) was ever used, so now (?J) at the
+    start sets both bits.
+
+4.  Added options (at build time, compile time, exec time) to change \R from
+    matching any Unicode line ending sequence to just matching CR, LF, or CRLF.
+
+5.  doc/pcresyntax.html was missing from the distribution.
+
+6.  Put back the definition of PCRE_ERROR_NULLWSLIMIT, for backward
+    compatibility, even though it is no longer used.
+
+7.  Added macro for snprintf to pcrecpp_unittest.cc and also for strtoll and
+    strtoull to pcrecpp.cc to select the available functions in WIN32 when the
+    windows.h file is present (where different names are used). [This was
+    reversed later after testing - see 16 below.]
+
+8.  Changed all #include <config.h> to #include "config.h". There were also
+    some further <pcre.h> cases that I changed to "pcre.h".
+
+9.  When pcregrep was used with the --colour option, it missed the line ending
+    sequence off the lines that it output.
+
+10. It was pointed out to me that arrays of string pointers cause lots of
+    relocations when a shared library is dynamically loaded. A technique of
+    using a single long string with a table of offsets can drastically reduce
+    these. I have refactored PCRE in four places to do this. The result is
+    dramatic:
+
+      Originally:                          290
+      After changing UCP table:            187
+      After changing error message table:   43
+      After changing table of "verbs"       36
+      After changing table of Posix names   22
+
+    Thanks to the folks working on Gregex for glib for this insight.
+
+11. --disable-stack-for-recursion caused compiling to fail unless -enable-
+    unicode-properties was also set.
+
+12. Updated the tests so that they work when \R is defaulted to ANYCRLF.
+
+13. Added checks for ANY and ANYCRLF to pcrecpp.cc where it previously
+    checked only for CRLF.
+
+14. Added casts to pcretest.c to avoid compiler warnings.
+
+15. Added Craig's patch to various pcrecpp modules to avoid compiler warnings.
+
+16. Added Craig's patch to remove the WINDOWS_H tests, that were not working,
+    and instead check for _strtoi64 explicitly, and avoid the use of snprintf()
+    entirely. This removes changes made in 7 above.
+
+17. The CMake files have been updated, and there is now more information about
+    building with CMake in the NON-UNIX-USE document.
+
+
+Version 7.3 28-Aug-07
+---------------------
+
+ 1. In the rejigging of the build system that eventually resulted in 7.1, the
+    line "#include <pcre.h>" was included in pcre_internal.h. The use of angle
+    brackets there is not right, since it causes compilers to look for an
+    installed pcre.h, not the version that is in the source that is being
+    compiled (which of course may be different). I have changed it back to:
+
+      #include "pcre.h"
+
+    I have a vague recollection that the change was concerned with compiling in
+    different directories, but in the new build system, that is taken care of
+    by the VPATH setting the Makefile.
+
+ 2. The pattern .*$ when run in not-DOTALL UTF-8 mode with newline=any failed
+    when the subject happened to end in the byte 0x85 (e.g. if the last
+    character was \x{1ec5}). *Character* 0x85 is one of the "any" newline
+    characters but of course it shouldn't be taken as a newline when it is part
+    of another character. The bug was that, for an unlimited repeat of . in
+    not-DOTALL UTF-8 mode, PCRE was advancing by bytes rather than by
+    characters when looking for a newline.
+
+ 3. A small performance improvement in the DOTALL UTF-8 mode .* case.
+
+ 4. Debugging: adjusted the names of opcodes for different kinds of parentheses
+    in debug output.
+
+ 5. Arrange to use "%I64d" instead of "%lld" and "%I64u" instead of "%llu" for
+    long printing in the pcrecpp unittest when running under MinGW.
+
+ 6. ESC_K was left out of the EBCDIC table.
+
+ 7. Change 7.0/38 introduced a new limit on the number of nested non-capturing
+    parentheses; I made it 1000, which seemed large enough. Unfortunately, the
+    limit also applies to "virtual nesting" when a pattern is recursive, and in
+    this case 1000 isn't so big. I have been able to remove this limit at the
+    expense of backing off one optimization in certain circumstances. Normally,
+    when pcre_exec() would call its internal match() function recursively and
+    immediately return the result unconditionally, it uses a "tail recursion"
+    feature to save stack. However, when a subpattern that can match an empty
+    string has an unlimited repetition quantifier, it no longer makes this
+    optimization. That gives it a stack frame in which to save the data for
+    checking that an empty string has been matched. Previously this was taken
+    from the 1000-entry workspace that had been reserved. So now there is no
+    explicit limit, but more stack is used.
+
+ 8. Applied Daniel's patches to solve problems with the import/export magic
+    syntax that is required for Windows, and which was going wrong for the
+    pcreposix and pcrecpp parts of the library. These were overlooked when this
+    problem was solved for the main library.
+
+ 9. There were some crude static tests to avoid integer overflow when computing
+    the size of patterns that contain repeated groups with explicit upper
+    limits. As the maximum quantifier is 65535, the maximum group length was
+    set at 30,000 so that the product of these two numbers did not overflow a
+    32-bit integer. However, it turns out that people want to use groups that
+    are longer than 30,000 bytes (though not repeat them that many times).
+    Change 7.0/17 (the refactoring of the way the pattern size is computed) has
+    made it possible to implement the integer overflow checks in a much more
+    dynamic way, which I have now done. The artificial limitation on group
+    length has been removed - we now have only the limit on the total length of
+    the compiled pattern, which depends on the LINK_SIZE setting.
+
+10. Fixed a bug in the documentation for get/copy named substring when
+    duplicate names are permitted. If none of the named substrings are set, the
+    functions return PCRE_ERROR_NOSUBSTRING (7); the doc said they returned an
+    empty string.
+
+11. Because Perl interprets \Q...\E at a high level, and ignores orphan \E
+    instances, patterns such as [\Q\E] or [\E] or even [^\E] cause an error,
+    because the ] is interpreted as the first data character and the
+    terminating ] is not found. PCRE has been made compatible with Perl in this
+    regard. Previously, it interpreted [\Q\E] as an empty class, and [\E] could
+    cause memory overwriting.
+
+10. Like Perl, PCRE automatically breaks an unlimited repeat after an empty
+    string has been matched (to stop an infinite loop). It was not recognizing
+    a conditional subpattern that could match an empty string if that
+    subpattern was within another subpattern. For example, it looped when
+    trying to match  (((?(1)X|))*)  but it was OK with  ((?(1)X|)*)  where the
+    condition was not nested. This bug has been fixed.
+
+12. A pattern like \X?\d or \P{L}?\d in non-UTF-8 mode could cause a backtrack
+    past the start of the subject in the presence of bytes with the top bit
+    set, for example "\x8aBCD".
+
+13. Added Perl 5.10 experimental backtracking controls (*FAIL), (*F), (*PRUNE),
+    (*SKIP), (*THEN), (*COMMIT), and (*ACCEPT).
+
+14. Optimized (?!) to (*FAIL).
+
+15. Updated the test for a valid UTF-8 string to conform to the later RFC 3629.
+    This restricts code points to be within the range 0 to 0x10FFFF, excluding
+    the "low surrogate" sequence 0xD800 to 0xDFFF. Previously, PCRE allowed the
+    full range 0 to 0x7FFFFFFF, as defined by RFC 2279. Internally, it still
+    does: it's just the validity check that is more restrictive.
+
+16. Inserted checks for integer overflows during escape sequence (backslash)
+    processing, and also fixed erroneous offset values for syntax errors during
+    backslash processing.
+
+17. Fixed another case of looking too far back in non-UTF-8 mode (cf 12 above)
+    for patterns like [\PPP\x8a]{1,}\x80 with the subject "A\x80".
+
+18. An unterminated class in a pattern like (?1)\c[ with a "forward reference"
+    caused an overrun.
+
+19. A pattern like (?:[\PPa*]*){8,} which had an "extended class" (one with
+    something other than just ASCII characters) inside a group that had an
+    unlimited repeat caused a loop at compile time (while checking to see
+    whether the group could match an empty string).
+
+20. Debugging a pattern containing \p or \P could cause a crash. For example,
+    [\P{Any}] did so. (Error in the code for printing property names.)
+
+21. An orphan \E inside a character class could cause a crash.
+
+22. A repeated capturing bracket such as (A)? could cause a wild memory
+    reference during compilation.
+
+23. There are several functions in pcre_compile() that scan along a compiled
+    expression for various reasons (e.g. to see if it's fixed length for look
+    behind). There were bugs in these functions when a repeated \p or \P was
+    present in the pattern. These operators have additional parameters compared
+    with \d, etc, and these were not being taken into account when moving along
+    the compiled data. Specifically:
+
+    (a) A item such as \p{Yi}{3} in a lookbehind was not treated as fixed
+        length.
+
+    (b) An item such as \pL+ within a repeated group could cause crashes or
+        loops.
+
+    (c) A pattern such as \p{Yi}+(\P{Yi}+)(?1) could give an incorrect
+        "reference to non-existent subpattern" error.
+
+    (d) A pattern like (\P{Yi}{2}\277)? could loop at compile time.
+
+24. A repeated \S or \W in UTF-8 mode could give wrong answers when multibyte
+    characters were involved (for example /\S{2}/8g with "A\x{a3}BC").
+
+25. Using pcregrep in multiline, inverted mode (-Mv) caused it to loop.
+
+26. Patterns such as [\P{Yi}A] which include \p or \P and just one other
+    character were causing crashes (broken optimization).
+
+27. Patterns such as (\P{Yi}*\277)* (group with possible zero repeat containing
+    \p or \P) caused a compile-time loop.
+
+28. More problems have arisen in unanchored patterns when CRLF is a valid line
+    break. For example, the unstudied pattern [\r\n]A does not match the string
+    "\r\nA" because change 7.0/46 below moves the current point on by two
+    characters after failing to match at the start. However, the pattern \nA
+    *does* match, because it doesn't start till \n, and if [\r\n]A is studied,
+    the same is true. There doesn't seem any very clean way out of this, but
+    what I have chosen to do makes the common cases work: PCRE now takes note
+    of whether there can be an explicit match for \r or \n anywhere in the
+    pattern, and if so, 7.0/46 no longer applies. As part of this change,
+    there's a new PCRE_INFO_HASCRORLF option for finding out whether a compiled
+    pattern has explicit CR or LF references.
+
+29. Added (*CR) etc for changing newline setting at start of pattern.
+
+
+Version 7.2 19-Jun-07
+---------------------
+
+ 1. If the fr_FR locale cannot be found for test 3, try the "french" locale,
+    which is apparently normally available under Windows.
+
+ 2. Re-jig the pcregrep tests with different newline settings in an attempt
+    to make them independent of the local environment's newline setting.
+
+ 3. Add code to configure.ac to remove -g from the CFLAGS default settings.
+
+ 4. Some of the "internals" tests were previously cut out when the link size
+    was not 2, because the output contained actual offsets. The recent new
+    "Z" feature of pcretest means that these can be cut out, making the tests
+    usable with all link sizes.
+
+ 5. Implemented Stan Switzer's goto replacement for longjmp() when not using
+    stack recursion. This gives a massive performance boost under BSD, but just
+    a small improvement under Linux. However, it saves one field in the frame
+    in all cases.
+
+ 6. Added more features from the forthcoming Perl 5.10:
+
+    (a) (?-n) (where n is a string of digits) is a relative subroutine or
+        recursion call. It refers to the nth most recently opened parentheses.
+
+    (b) (?+n) is also a relative subroutine call; it refers to the nth next
+        to be opened parentheses.
+
+    (c) Conditions that refer to capturing parentheses can be specified
+        relatively, for example, (?(-2)... or (?(+3)...
+
+    (d) \K resets the start of the current match so that everything before
+        is not part of it.
+
+    (e) \k{name} is synonymous with \k<name> and \k'name' (.NET compatible).
+
+    (f) \g{name} is another synonym - part of Perl 5.10's unification of
+        reference syntax.
+
+    (g) (?| introduces a group in which the numbering of parentheses in each
+        alternative starts with the same number.
+
+    (h) \h, \H, \v, and \V match horizontal and vertical whitespace.
+
+ 7. Added two new calls to pcre_fullinfo(): PCRE_INFO_OKPARTIAL and
+    PCRE_INFO_JCHANGED.
+
+ 8. A pattern such as  (.*(.)?)*  caused pcre_exec() to fail by either not
+    terminating or by crashing. Diagnosed by Viktor Griph; it was in the code
+    for detecting groups that can match an empty string.
+
+ 9. A pattern with a very large number of alternatives (more than several
+    hundred) was running out of internal workspace during the pre-compile
+    phase, where pcre_compile() figures out how much memory will be needed. A
+    bit of new cunning has reduced the workspace needed for groups with
+    alternatives. The 1000-alternative test pattern now uses 12 bytes of
+    workspace instead of running out of the 4096 that are available.
+
+10. Inserted some missing (unsigned int) casts to get rid of compiler warnings.
+
+11. Applied patch from Google to remove an optimization that didn't quite work.
+    The report of the bug said:
+
+      pcrecpp::RE("a*").FullMatch("aaa") matches, while
+      pcrecpp::RE("a*?").FullMatch("aaa") does not, and
+      pcrecpp::RE("a*?\\z").FullMatch("aaa") does again.
+
+12. If \p or \P was used in non-UTF-8 mode on a character greater than 127
+    it matched the wrong number of bytes.
+
+
+Version 7.1 24-Apr-07
+---------------------
+
+ 1. Applied Bob Rossi and Daniel G's patches to convert the build system to one
+    that is more "standard", making use of automake and other Autotools. There
+    is some re-arrangement of the files and adjustment of comments consequent
+    on this.
+
+ 2. Part of the patch fixed a problem with the pcregrep tests. The test of -r
+    for recursive directory scanning broke on some systems because the files
+    are not scanned in any specific order and on different systems the order
+    was different. A call to "sort" has been inserted into RunGrepTest for the
+    approprate test as a short-term fix. In the longer term there may be an
+    alternative.
+
+ 3. I had an email from Eric Raymond about problems translating some of PCRE's
+    man pages to HTML (despite the fact that I distribute HTML pages, some
+    people do their own conversions for various reasons). The problems
+    concerned the use of low-level troff macros .br and .in. I have therefore
+    removed all such uses from the man pages (some were redundant, some could
+    be replaced by .nf/.fi pairs). The 132html script that I use to generate
+    HTML has been updated to handle .nf/.fi and to complain if it encounters
+    .br or .in.
+
+ 4. Updated comments in configure.ac that get placed in config.h.in and also
+    arranged for config.h to be included in the distribution, with the name
+    config.h.generic, for the benefit of those who have to compile without
+    Autotools (compare pcre.h, which is now distributed as pcre.h.generic).
+
+ 5. Updated the support (such as it is) for Virtual Pascal, thanks to Stefan
+    Weber: (1) pcre_internal.h was missing some function renames; (2) updated
+    makevp.bat for the current PCRE, using the additional files
+    makevp_c.txt, makevp_l.txt, and pcregexp.pas.
+
+ 6. A Windows user reported a minor discrepancy with test 2, which turned out
+    to be caused by a trailing space on an input line that had got lost in his
+    copy. The trailing space was an accident, so I've just removed it.
+
+ 7. Add -Wl,-R... flags in pcre-config.in for *BSD* systems, as I'm told
+    that is needed.
+
+ 8. Mark ucp_table (in ucptable.h) and ucp_gentype (in pcre_ucp_searchfuncs.c)
+    as "const" (a) because they are and (b) because it helps the PHP
+    maintainers who have recently made a script to detect big data structures
+    in the php code that should be moved to the .rodata section. I remembered
+    to update Builducptable as well, so it won't revert if ucptable.h is ever
+    re-created.
+
+ 9. Added some extra #ifdef SUPPORT_UTF8 conditionals into pcretest.c,
+    pcre_printint.src, pcre_compile.c, pcre_study.c, and pcre_tables.c, in
+    order to be able to cut out the UTF-8 tables in the latter when UTF-8
+    support is not required. This saves 1.5-2K of code, which is important in
+    some applications.
+
+    Later: more #ifdefs are needed in pcre_ord2utf8.c and pcre_valid_utf8.c
+    so as not to refer to the tables, even though these functions will never be
+    called when UTF-8 support is disabled. Otherwise there are problems with a
+    shared library.
+
+10. Fixed two bugs in the emulated memmove() function in pcre_internal.h:
+
+    (a) It was defining its arguments as char * instead of void *.
+
+    (b) It was assuming that all moves were upwards in memory; this was true
+        a long time ago when I wrote it, but is no longer the case.
+
+    The emulated memove() is provided for those environments that have neither
+    memmove() nor bcopy(). I didn't think anyone used it these days, but that
+    is clearly not the case, as these two bugs were recently reported.
+
+11. The script PrepareRelease is now distributed: it calls 132html, CleanTxt,
+    and Detrail to create the HTML documentation, the .txt form of the man
+    pages, and it removes trailing spaces from listed files. It also creates
+    pcre.h.generic and config.h.generic from pcre.h and config.h. In the latter
+    case, it wraps all the #defines with #ifndefs. This script should be run
+    before "make dist".
+
+12. Fixed two fairly obscure bugs concerned with quantified caseless matching
+    with Unicode property support.
+
+    (a) For a maximizing quantifier, if the two different cases of the
+        character were of different lengths in their UTF-8 codings (there are
+        some cases like this - I found 11), and the matching function had to
+        back up over a mixture of the two cases, it incorrectly assumed they
+        were both the same length.
+
+    (b) When PCRE was configured to use the heap rather than the stack for
+        recursion during matching, it was not correctly preserving the data for
+        the other case of a UTF-8 character when checking ahead for a match
+        while processing a minimizing repeat. If the check also involved
+        matching a wide character, but failed, corruption could cause an
+        erroneous result when trying to check for a repeat of the original
+        character.
+
+13. Some tidying changes to the testing mechanism:
+
+    (a) The RunTest script now detects the internal link size and whether there
+        is UTF-8 and UCP support by running ./pcretest -C instead of relying on
+        values substituted by "configure". (The RunGrepTest script already did
+        this for UTF-8.) The configure.ac script no longer substitutes the
+        relevant variables.
+
+    (b) The debugging options /B and /D in pcretest show the compiled bytecode
+        with length and offset values. This means that the output is different
+        for different internal link sizes. Test 2 is skipped for link sizes
+        other than 2 because of this, bypassing the problem. Unfortunately,
+        there was also a test in test 3 (the locale tests) that used /B and
+        failed for link sizes other than 2. Rather than cut the whole test out,
+        I have added a new /Z option to pcretest that replaces the length and
+        offset values with spaces. This is now used to make test 3 independent
+        of link size. (Test 2 will be tidied up later.)
+
+14. If erroroffset was passed as NULL to pcre_compile, it provoked a
+    segmentation fault instead of returning the appropriate error message.
+
+15. In multiline mode when the newline sequence was set to "any", the pattern
+    ^$ would give a match between the \r and \n of a subject such as "A\r\nB".
+    This doesn't seem right; it now treats the CRLF combination as the line
+    ending, and so does not match in that case. It's only a pattern such as ^$
+    that would hit this one: something like ^ABC$ would have failed after \r
+    and then tried again after \r\n.
+
+16. Changed the comparison command for RunGrepTest from "diff -u" to "diff -ub"
+    in an attempt to make files that differ only in their line terminators
+    compare equal. This works on Linux.
+
+17. Under certain error circumstances pcregrep might try to free random memory
+    as it exited. This is now fixed, thanks to valgrind.
+
+19. In pcretest, if the pattern /(?m)^$/g<any> was matched against the string
+    "abc\r\n\r\n", it found an unwanted second match after the second \r. This
+    was because its rules for how to advance for /g after matching an empty
+    string at the end of a line did not allow for this case. They now check for
+    it specially.
+
+20. pcretest is supposed to handle patterns and data of any length, by
+    extending its buffers when necessary. It was getting this wrong when the
+    buffer for a data line had to be extended.
+
+21. Added PCRE_NEWLINE_ANYCRLF which is like ANY, but matches only CR, LF, or
+    CRLF as a newline sequence.
+
+22. Code for handling Unicode properties in pcre_dfa_exec() wasn't being cut
+    out by #ifdef SUPPORT_UCP. This did no harm, as it could never be used, but
+    I have nevertheless tidied it up.
+
+23. Added some casts to kill warnings from HP-UX ia64 compiler.
+
+24. Added a man page for pcre-config.
+
+
+Version 7.0 19-Dec-06
+---------------------
+
+ 1. Fixed a signed/unsigned compiler warning in pcre_compile.c, shown up by
+    moving to gcc 4.1.1.
+
+ 2. The -S option for pcretest uses setrlimit(); I had omitted to #include
+    sys/time.h, which is documented as needed for this function. It doesn't
+    seem to matter on Linux, but it showed up on some releases of OS X.
+
+ 3. It seems that there are systems where bytes whose values are greater than
+    127 match isprint() in the "C" locale. The "C" locale should be the
+    default when a C program starts up. In most systems, only ASCII printing
+    characters match isprint(). This difference caused the output from pcretest
+    to vary, making some of the tests fail. I have changed pcretest so that:
+
+    (a) When it is outputting text in the compiled version of a pattern, bytes
+        other than 32-126 are always shown as hex escapes.
+
+    (b) When it is outputting text that is a matched part of a subject string,
+        it does the same, unless a different locale has been set for the match
+        (using the /L modifier). In this case, it uses isprint() to decide.
+
+ 4. Fixed a major bug that caused incorrect computation of the amount of memory
+    required for a compiled pattern when options that changed within the
+    pattern affected the logic of the preliminary scan that determines the
+    length. The relevant options are -x, and -i in UTF-8 mode. The result was
+    that the computed length was too small. The symptoms of this bug were
+    either the PCRE error "internal error: code overflow" from pcre_compile(),
+    or a glibc crash with a message such as "pcretest: free(): invalid next
+    size (fast)". Examples of patterns that provoked this bug (shown in
+    pcretest format) are:
+
+      /(?-x: )/x
+      /(?x)(?-x: \s*#\s*)/
+      /((?i)[\x{c0}])/8
+      /(?i:[\x{c0}])/8
+
+    HOWEVER: Change 17 below makes this fix obsolete as the memory computation
+    is now done differently.
+
+ 5. Applied patches from Google to: (a) add a QuoteMeta function to the C++
+    wrapper classes; (b) implement a new function in the C++ scanner that is
+    more efficient than the old way of doing things because it avoids levels of
+    recursion in the regex matching; (c) add a paragraph to the documentation
+    for the FullMatch() function.
+
+ 6. The escape sequence \n was being treated as whatever was defined as
+    "newline". Not only was this contrary to the documentation, which states
+    that \n is character 10 (hex 0A), but it also went horribly wrong when
+    "newline" was defined as CRLF. This has been fixed.
+
+ 7. In pcre_dfa_exec.c the value of an unsigned integer (the variable called c)
+    was being set to -1 for the "end of line" case (supposedly a value that no
+    character can have). Though this value is never used (the check for end of
+    line is "zero bytes in current character"), it caused compiler complaints.
+    I've changed it to 0xffffffff.
+
+ 8. In pcre_version.c, the version string was being built by a sequence of
+    C macros that, in the event of PCRE_PRERELEASE being defined as an empty
+    string (as it is for production releases) called a macro with an empty
+    argument. The C standard says the result of this is undefined. The gcc
+    compiler treats it as an empty string (which was what was wanted) but it is
+    reported that Visual C gives an error. The source has been hacked around to
+    avoid this problem.
+
+ 9. On the advice of a Windows user, included <io.h> and <fcntl.h> in Windows
+    builds of pcretest, and changed the call to _setmode() to use _O_BINARY
+    instead of 0x8000. Made all the #ifdefs test both _WIN32 and WIN32 (not all
+    of them did).
+
+10. Originally, pcretest opened its input and output without "b"; then I was
+    told that "b" was needed in some environments, so it was added for release
+    5.0 to both the input and output. (It makes no difference on Unix-like
+    systems.) Later I was told that it is wrong for the input on Windows. I've
+    now abstracted the modes into two macros, to make it easier to fiddle with
+    them, and removed "b" from the input mode under Windows.
+
+11. Added pkgconfig support for the C++ wrapper library, libpcrecpp.
+
+12. Added -help and --help to pcretest as an official way of being reminded
+    of the options.
+
+13. Removed some redundant semicolons after macro calls in pcrecpparg.h.in
+    and pcrecpp.cc because they annoy compilers at high warning levels.
+
+14. A bit of tidying/refactoring in pcre_exec.c in the main bumpalong loop.
+
+15. Fixed an occurrence of == in configure.ac that should have been = (shell
+    scripts are not C programs :-) and which was not noticed because it works
+    on Linux.
+
+16. pcretest is supposed to handle any length of pattern and data line (as one
+    line or as a continued sequence of lines) by extending its input buffer if
+    necessary. This feature was broken for very long pattern lines, leading to
+    a string of junk being passed to pcre_compile() if the pattern was longer
+    than about 50K.
+
+17. I have done a major re-factoring of the way pcre_compile() computes the
+    amount of memory needed for a compiled pattern. Previously, there was code
+    that made a preliminary scan of the pattern in order to do this. That was
+    OK when PCRE was new, but as the facilities have expanded, it has become
+    harder and harder to keep it in step with the real compile phase, and there
+    have been a number of bugs (see for example, 4 above). I have now found a
+    cunning way of running the real compile function in a "fake" mode that
+    enables it to compute how much memory it would need, while actually only
+    ever using a few hundred bytes of working memory and without too many
+    tests of the mode. This should make future maintenance and development
+    easier. A side effect of this work is that the limit of 200 on the nesting
+    depth of parentheses has been removed (though this was never a serious
+    limitation, I suspect). However, there is a downside: pcre_compile() now
+    runs more slowly than before (30% or more, depending on the pattern). I
+    hope this isn't a big issue. There is no effect on runtime performance.
+
+18. Fixed a minor bug in pcretest: if a pattern line was not terminated by a
+    newline (only possible for the last line of a file) and it was a
+    pattern that set a locale (followed by /Lsomething), pcretest crashed.
+
+19. Added additional timing features to pcretest. (1) The -tm option now times
+    matching only, not compiling. (2) Both -t and -tm can be followed, as a
+    separate command line item, by a number that specifies the number of
+    repeats to use when timing. The default is 50000; this gives better
+    precision, but takes uncomfortably long for very large patterns.
+
+20. Extended pcre_study() to be more clever in cases where a branch of a
+    subpattern has no definite first character. For example, (a*|b*)[cd] would
+    previously give no result from pcre_study(). Now it recognizes that the
+    first character must be a, b, c, or d.
+
+21. There was an incorrect error "recursive call could loop indefinitely" if
+    a subpattern (or the entire pattern) that was being tested for matching an
+    empty string contained only one non-empty item after a nested subpattern.
+    For example, the pattern (?>\x{100}*)\d(?R) provoked this error
+    incorrectly, because the \d was being skipped in the check.
+
+22. The pcretest program now has a new pattern option /B and a command line
+    option -b, which is equivalent to adding /B to every pattern. This causes
+    it to show the compiled bytecode, without the additional information that
+    -d shows. The effect of -d is now the same as -b with -i (and similarly, /D
+    is the same as /B/I).
+
+23. A new optimization is now able automatically to treat some sequences such
+    as a*b as a*+b. More specifically, if something simple (such as a character
+    or a simple class like \d) has an unlimited quantifier, and is followed by
+    something that cannot possibly match the quantified thing, the quantifier
+    is automatically "possessified".
+
+24. A recursive reference to a subpattern whose number was greater than 39
+    went wrong under certain circumstances in UTF-8 mode. This bug could also
+    have affected the operation of pcre_study().
+
+25. Realized that a little bit of performance could be had by replacing
+    (c & 0xc0) == 0xc0 with c >= 0xc0 when processing UTF-8 characters.
+
+26. Timing data from pcretest is now shown to 4 decimal places instead of 3.
+
+27. Possessive quantifiers such as a++ were previously implemented by turning
+    them into atomic groups such as ($>a+). Now they have their own opcodes,
+    which improves performance. This includes the automatically created ones
+    from 23 above.
+
+28. A pattern such as (?=(\w+))\1: which simulates an atomic group using a
+    lookahead was broken if it was not anchored. PCRE was mistakenly expecting
+    the first matched character to be a colon. This applied both to named and
+    numbered groups.
+
+29. The ucpinternal.h header file was missing its idempotency #ifdef.
+
+30. I was sent a "project" file called libpcre.a.dev which I understand makes
+    building PCRE on Windows easier, so I have included it in the distribution.
+
+31. There is now a check in pcretest against a ridiculously large number being
+    returned by pcre_exec() or pcre_dfa_exec(). If this happens in a /g or /G
+    loop, the loop is abandoned.
+
+32. Forward references to subpatterns in conditions such as (?(2)...) where
+    subpattern 2 is defined later cause pcre_compile() to search forwards in
+    the pattern for the relevant set of parentheses. This search went wrong
+    when there were unescaped parentheses in a character class, parentheses
+    escaped with \Q...\E, or parentheses in a #-comment in /x mode.
+
+33. "Subroutine" calls and backreferences were previously restricted to
+    referencing subpatterns earlier in the regex. This restriction has now
+    been removed.
+
+34. Added a number of extra features that are going to be in Perl 5.10. On the
+    whole, these are just syntactic alternatives for features that PCRE had
+    previously implemented using the Python syntax or my own invention. The
+    other formats are all retained for compatibility.
+
+    (a) Named groups can now be defined as (?<name>...) or (?'name'...) as well
+        as (?P<name>...). The new forms, as well as being in Perl 5.10, are
+        also .NET compatible.
+
+    (b) A recursion or subroutine call to a named group can now be defined as
+        (?&name) as well as (?P>name).
+
+    (c) A backreference to a named group can now be defined as \k<name> or
+        \k'name' as well as (?P=name). The new forms, as well as being in Perl
+        5.10, are also .NET compatible.
+
+    (d) A conditional reference to a named group can now use the syntax
+        (?(<name>) or (?('name') as well as (?(name).
+
+    (e) A "conditional group" of the form (?(DEFINE)...) can be used to define
+        groups (named and numbered) that are never evaluated inline, but can be
+        called as "subroutines" from elsewhere. In effect, the DEFINE condition
+        is always false. There may be only one alternative in such a group.
+
+    (f) A test for recursion can be given as (?(R1).. or (?(R&name)... as well
+        as the simple (?(R). The condition is true only if the most recent
+        recursion is that of the given number or name. It does not search out
+        through the entire recursion stack.
+
+    (g) The escape \gN or \g{N} has been added, where N is a positive or
+        negative number, specifying an absolute or relative reference.
+
+35. Tidied to get rid of some further signed/unsigned compiler warnings and
+    some "unreachable code" warnings.
+
+36. Updated the Unicode property tables to Unicode version 5.0.0. Amongst other
+    things, this adds five new scripts.
+
+37. Perl ignores orphaned \E escapes completely. PCRE now does the same.
+    There were also incompatibilities regarding the handling of \Q..\E inside
+    character classes, for example with patterns like [\Qa\E-\Qz\E] where the
+    hyphen was adjacent to \Q or \E. I hope I've cleared all this up now.
+
+38. Like Perl, PCRE detects when an indefinitely repeated parenthesized group
+    matches an empty string, and forcibly breaks the loop. There were bugs in
+    this code in non-simple cases. For a pattern such as  ^(a()*)*  matched
+    against  aaaa  the result was just "a" rather than "aaaa", for example. Two
+    separate and independent bugs (that affected different cases) have been
+    fixed.
+
+39. Refactored the code to abolish the use of different opcodes for small
+    capturing bracket numbers. This is a tidy that I avoided doing when I
+    removed the limit on the number of capturing brackets for 3.5 back in 2001.
+    The new approach is not only tidier, it makes it possible to reduce the
+    memory needed to fix the previous bug (38).
+
+40. Implemented PCRE_NEWLINE_ANY to recognize any of the Unicode newline
+    sequences (http://unicode.org/unicode/reports/tr18/) as "newline" when
+    processing dot, circumflex, or dollar metacharacters, or #-comments in /x
+    mode.
+
+41. Add \R to match any Unicode newline sequence, as suggested in the Unicode
+    report.
+
+42. Applied patch, originally from Ari Pollak, modified by Google, to allow
+    copy construction and assignment in the C++ wrapper.
+
+43. Updated pcregrep to support "--newline=any". In the process, I fixed a
+    couple of bugs that could have given wrong results in the "--newline=crlf"
+    case.
+
+44. Added a number of casts and did some reorganization of signed/unsigned int
+    variables following suggestions from Dair Grant. Also renamed the variable
+    "this" as "item" because it is a C++ keyword.
+
+45. Arranged for dftables to add
+
+      #include "pcre_internal.h"
+
+    to pcre_chartables.c because without it, gcc 4.x may remove the array
+    definition from the final binary if PCRE is built into a static library and
+    dead code stripping is activated.
+
+46. For an unanchored pattern, if a match attempt fails at the start of a
+    newline sequence, and the newline setting is CRLF or ANY, and the next two
+    characters are CRLF, advance by two characters instead of one.

+Technical Notes about PCRE
+--------------------------
+
+These are very rough technical notes that record potentially useful information 
+about PCRE internals.
+
+Historical note 1
+-----------------
+
+Many years ago I implemented some regular expression functions to an algorithm
+suggested by Martin Richards. These were not Unix-like in form, and were quite
+restricted in what they could do by comparison with Perl. The interesting part
+about the algorithm was that the amount of space required to hold the compiled
+form of an expression was known in advance. The code to apply an expression did
+not operate by backtracking, as the original Henry Spencer code and current
+Perl code does, but instead checked all possibilities simultaneously by keeping
+a list of current states and checking all of them as it advanced through the
+subject string. In the terminology of Jeffrey Friedl's book, it was a "DFA
+algorithm", though it was not a traditional Finite State Machine (FSM). When
+the pattern was all used up, all remaining states were possible matches, and
+the one matching the longest subset of the subject string was chosen. This did
+not necessarily maximize the individual wild portions of the pattern, as is
+expected in Unix and Perl-style regular expressions.
+
+Historical note 2
+-----------------
+
+By contrast, the code originally written by Henry Spencer (which was
+subsequently heavily modified for Perl) compiles the expression twice: once in
+a dummy mode in order to find out how much store will be needed, and then for
+real. (The Perl version probably doesn't do this any more; I'm talking about
+the original library.) The execution function operates by backtracking and
+maximizing (or, optionally, minimizing in Perl) the amount of the subject that
+matches individual wild portions of the pattern. This is an "NFA algorithm" in
+Friedl's terminology.
+
+OK, here's the real stuff
+-------------------------
+
+For the set of functions that form the "basic" PCRE library (which are
+unrelated to those mentioned above), I tried at first to invent an algorithm
+that used an amount of store bounded by a multiple of the number of characters
+in the pattern, to save on compiling time. However, because of the greater
+complexity in Perl regular expressions, I couldn't do this. In any case, a
+first pass through the pattern is helpful for other reasons. 
+
+Computing the memory requirement: how it was
+--------------------------------------------
+
+Up to and including release 6.7, PCRE worked by running a very degenerate first
+pass to calculate a maximum store size, and then a second pass to do the real
+compile - which might use a bit less than the predicted amount of memory. The
+idea was that this would turn out faster than the Henry Spencer code because
+the first pass is degenerate and the second pass can just store stuff straight
+into the vector, which it knows is big enough.
+
+Computing the memory requirement: how it is
+-------------------------------------------
+
+By the time I was working on a potential 6.8 release, the degenerate first pass
+had become very complicated and hard to maintain. Indeed one of the early
+things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then
+I had a flash of inspiration as to how I could run the real compile function in
+a "fake" mode that enables it to compute how much memory it would need, while
+actually only ever using a few hundred bytes of working memory, and without too
+many tests of the mode that might slow it down. So I re-factored the compiling
+functions to work this way. This got rid of about 600 lines of source. It
+should make future maintenance and development easier. As this was such a major 
+change, I never released 6.8, instead upping the number to 7.0 (other quite 
+major changes are also present in the 7.0 release).
+
+A side effect of this work is that the previous limit of 200 on the nesting
+depth of parentheses was removed. However, there is a downside: pcre_compile()
+runs more slowly than before (30% or more, depending on the pattern) because it
+is doing a full analysis of the pattern. My hope is that this is not a big
+issue.
+
+Traditional matching function
+-----------------------------
+
+The "traditional", and original, matching function is called pcre_exec(), and 
+it implements an NFA algorithm, similar to the original Henry Spencer algorithm 
+and the way that Perl works. Not surprising, since it is intended to be as 
+compatible with Perl as possible. This is the function most users of PCRE will 
+use most of the time.
+
+Supplementary matching function
+-------------------------------
+
+From PCRE 6.0, there is also a supplementary matching function called 
+pcre_dfa_exec(). This implements a DFA matching algorithm that searches 
+simultaneously for all possible matches that start at one point in the subject 
+string. (Going back to my roots: see Historical Note 1 above.) This function 
+intreprets the same compiled pattern data as pcre_exec(); however, not all the 
+facilities are available, and those that are do not always work in quite the 
+same way. See the user documentation for details.
+
+The algorithm that is used for pcre_dfa_exec() is not a traditional FSM, 
+because it may have a number of states active at one time. More work would be 
+needed at compile time to produce a traditional FSM where only one state is 
+ever active at once. I believe some other regex matchers work this way.
+
+
+Format of compiled patterns
+---------------------------
+
+The compiled form of a pattern is a vector of bytes, containing items of
+variable length. The first byte in an item is an opcode, and the length of the
+item is either implicit in the opcode or contained in the data bytes that
+follow it. 
+
+In many cases below LINK_SIZE data values are specified for offsets within the 
+compiled pattern. The default value for LINK_SIZE is 2, but PCRE can be
+compiled to use 3-byte or 4-byte values for these offsets (impairing the
+performance). This is necessary only when patterns whose compiled length is
+greater than 64K are going to be processed. In this description, we assume the
+"normal" compilation options. Data values that are counts (e.g. for
+quantifiers) are always just two bytes long.
+
+A list of the opcodes follows:
+
+Opcodes with no following data
+------------------------------
+
+These items are all just one byte long
+
+  OP_END                 end of pattern
+  OP_ANY                 match any one character other than newline
+  OP_ALLANY              match any one character, including newline
+  OP_ANYBYTE             match any single byte, even in UTF-8 mode
+  OP_SOD                 match start of data: \A
+  OP_SOM,                start of match (subject + offset): \G
+  OP_SET_SOM,            set start of match (\K) 
+  OP_CIRC                ^ (start of data, or after \n in multiline)
+  OP_NOT_WORD_BOUNDARY   \W
+  OP_WORD_BOUNDARY       \w
+  OP_NOT_DIGIT           \D
+  OP_DIGIT               \d
+  OP_NOT_HSPACE          \H
+  OP_HSPACE              \h  
+  OP_NOT_WHITESPACE      \S
+  OP_WHITESPACE          \s
+  OP_NOT_VSPACE          \V
+  OP_VSPACE              \v  
+  OP_NOT_WORDCHAR        \W
+  OP_WORDCHAR            \w
+  OP_EODN                match end of data or \n at end: \Z
+  OP_EOD                 match end of data: \z
+  OP_DOLL                $ (end of data, or before \n in multiline)
+  OP_EXTUNI              match an extended Unicode character 
+  OP_ANYNL               match any Unicode newline sequence 
+  
+  OP_ACCEPT              )
+  OP_COMMIT              ) 
+  OP_FAIL                ) These are Perl 5.10's "backtracking     
+  OP_PRUNE               ) control verbs".                         
+  OP_SKIP                )
+  OP_THEN                )
+  
+
+Repeating single characters
+---------------------------
+
+The common repeats (*, +, ?) when applied to a single character use the
+following opcodes:
+
+  OP_STAR
+  OP_MINSTAR
+  OP_POSSTAR 
+  OP_PLUS
+  OP_MINPLUS
+  OP_POSPLUS 
+  OP_QUERY
+  OP_MINQUERY
+  OP_POSQUERY 
+
+In ASCII mode, these are two-byte items; in UTF-8 mode, the length is variable.
+Those with "MIN" in their name are the minimizing versions. Those with "POS" in 
+their names are possessive versions. Each is followed by the character that is
+to be repeated. Other repeats make use of
+
+  OP_UPTO
+  OP_MINUPTO
+  OP_POSUPTO 
+  OP_EXACT
+
+which are followed by a two-byte count (most significant first) and the
+repeated character. OP_UPTO matches from 0 to the given number. A repeat with a
+non-zero minimum and a fixed maximum is coded as an OP_EXACT followed by an
+OP_UPTO (or OP_MINUPTO or OPT_POSUPTO).
+
+
+Repeating character types
+-------------------------
+
+Repeats of things like \d are done exactly as for single characters, except
+that instead of a character, the opcode for the type is stored in the data
+byte. The opcodes are:
+
+  OP_TYPESTAR
+  OP_TYPEMINSTAR
+  OP_TYPEPOSSTAR 
+  OP_TYPEPLUS
+  OP_TYPEMINPLUS
+  OP_TYPEPOSPLUS 
+  OP_TYPEQUERY
+  OP_TYPEMINQUERY
+  OP_TYPEPOSQUERY 
+  OP_TYPEUPTO
+  OP_TYPEMINUPTO
+  OP_TYPEPOSUPTO 
+  OP_TYPEEXACT
+
+
+Match by Unicode property
+-------------------------
+
+OP_PROP and OP_NOTPROP are used for positive and negative matches of a 
+character by testing its Unicode property (the \p and \P escape sequences).
+Each is followed by two bytes that encode the desired property as a type and a 
+value.
+
+Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by 
+three bytes: OP_PROP or OP_NOTPROP and then the desired property type and 
+value.
+
+
+Matching literal characters
+---------------------------
+
+The OP_CHAR opcode is followed by a single character that is to be matched 
+casefully. For caseless matching, OP_CHARNC is used. In UTF-8 mode, the 
+character may be more than one byte long. (Earlier versions of PCRE used 
+multi-character strings, but this was changed to allow some new features to be 
+added.)
+
+
+Character classes
+-----------------
+
+If there is only one character, OP_CHAR or OP_CHARNC is used for a positive
+class, and OP_NOT for a negative one (that is, for something like [^a]).
+However, in UTF-8 mode, the use of OP_NOT applies only to characters with
+values < 128, because OP_NOT is confined to single bytes.
+
+Another set of repeating opcodes (OP_NOTSTAR etc.) are used for a repeated,
+negated, single-character class. The normal ones (OP_STAR etc.) are used for a
+repeated positive single-character class.
+
+When there's more than one character in a class and all the characters are less
+than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a negative
+one. In either case, the opcode is followed by a 32-byte bit map containing a 1
+bit for every character that is acceptable. The bits are counted from the least
+significant end of each byte.
+
+The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 mode,
+subject characters with values greater than 256 can be handled correctly. For
+OP_CLASS they don't match, whereas for OP_NCLASS they do.
+
+For classes containing characters with values > 255, OP_XCLASS is used. It
+optionally uses a bit map (if any characters lie within it), followed by a list
+of pairs and single characters. There is a flag character than indicates
+whether it's a positive or a negative class.
+
+
+Back references
+---------------
+
+OP_REF is followed by two bytes containing the reference number.
+
+
+Repeating character classes and back references
+-----------------------------------------------
+
+Single-character classes are handled specially (see above). This section
+applies to OP_CLASS and OP_REF. In both cases, the repeat information follows
+the base item. The matching code looks at the following opcode to see if it is
+one of
+
+  OP_CRSTAR
+  OP_CRMINSTAR
+  OP_CRPLUS
+  OP_CRMINPLUS
+  OP_CRQUERY
+  OP_CRMINQUERY
+  OP_CRRANGE
+  OP_CRMINRANGE
+
+All but the last two are just single-byte items. The others are followed by
+four bytes of data, comprising the minimum and maximum repeat counts. There are 
+no special possessive opcodes for these repeats; a possessive repeat is 
+compiled into an atomic group.
+
+
+Brackets and alternation
+------------------------
+
+A pair of non-capturing (round) brackets is wrapped round each expression at
+compile time, so alternation always happens in the context of brackets.
+
+[Note for North Americans: "bracket" to some English speakers, including
+myself, can be round, square, curly, or pointy. Hence this usage.]
+
+Non-capturing brackets use the opcode OP_BRA. Originally PCRE was limited to 99
+capturing brackets and it used a different opcode for each one. From release
+3.5, the limit was removed by putting the bracket number into the data for
+higher-numbered brackets. From release 7.0 all capturing brackets are handled
+this way, using the single opcode OP_CBRA.
+
+A bracket opcode is followed by LINK_SIZE bytes which give the offset to the
+next alternative OP_ALT or, if there aren't any branches, to the matching
+OP_KET opcode. Each OP_ALT is followed by LINK_SIZE bytes giving the offset to
+the next one, or to the OP_KET opcode. For capturing brackets, the bracket 
+number immediately follows the offset, always as a 2-byte item.
+
+OP_KET is used for subpatterns that do not repeat indefinitely, while
+OP_KETRMIN and OP_KETRMAX are used for indefinite repetitions, minimally or
+maximally respectively. All three are followed by LINK_SIZE bytes giving (as a
+positive number) the offset back to the matching bracket opcode.
+
+If a subpattern is quantified such that it is permitted to match zero times, it
+is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are
+single-byte opcodes that tell the matcher that skipping the following
+subpattern entirely is a valid branch. In the case of the first two, not 
+skipping the pattern is also valid (greedy and non-greedy). The third is used 
+when a pattern has the quantifier {0,0}. It cannot be entirely discarded, 
+because it may be called as a subroutine from elsewhere in the regex.
+
+A subpattern with an indefinite maximum repetition is replicated in the
+compiled data its minimum number of times (or once with OP_BRAZERO if the
+minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX
+as appropriate.
+
+A subpattern with a bounded maximum repetition is replicated in a nested
+fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO
+before each replication after the minimum, so that, for example, (abc){2,5} is
+compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group 
+has the same number.
+
+When a repeated subpattern has an unbounded upper limit, it is checked to see 
+whether it could match an empty string. If this is the case, the opcode in the 
+final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher
+that it needs to check for matching an empty string when it hits OP_KETRMIN or
+OP_KETRMAX, and if so, to break the loop.
+
+
+Assertions
+----------
+
+Forward assertions are just like other subpatterns, but starting with one of
+the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes
+OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion
+is OP_REVERSE, followed by a two byte count of the number of characters to move
+back the pointer in the subject string. When operating in UTF-8 mode, the count
+is a character count rather than a byte count. A separate count is present in
+each alternative of a lookbehind assertion, allowing them to have different
+fixed lengths.
+
+
+Once-only (atomic) subpatterns
+------------------------------
+
+These are also just like other subpatterns, but they start with the opcode
+OP_ONCE. The check for matching an empty string in an unbounded repeat is 
+handled entirely at runtime, so there is just this one opcode.
+
+
+Conditional subpatterns
+-----------------------
+
+These are like other subpatterns, but they start with the opcode OP_COND, or
+OP_SCOND for one that might match an empty string in an unbounded repeat. If
+the condition is a back reference, this is stored at the start of the
+subpattern using the opcode OP_CREF followed by two bytes containing the
+reference number. If the condition is "in recursion" (coded as "(?(R)"), or "in
+recursion of group x" (coded as "(?(Rx)"), the group number is stored at the
+start of the subpattern using the opcode OP_RREF, and a value of zero for "the
+whole pattern". For a DEFINE condition, just the single byte OP_DEF is used (it
+has no associated data). Otherwise, a conditional subpattern always starts with
+one of the assertions.
+
+
+Recursion
+---------
+
+Recursion either matches the current regex, or some subexpression. The opcode
+OP_RECURSE is followed by an value which is the offset to the starting bracket
+from the start of the whole pattern. From release 6.5, OP_RECURSE is 
+automatically wrapped inside OP_ONCE brackets (because otherwise some patterns 
+broke it). OP_RECURSE is also used for "subroutine" calls, even though they 
+are not strictly a recursion.
+
+
+Callout
+-------
+
+OP_CALLOUT is followed by one byte of data that holds a callout number in the
+range 0 to 254 for manual callouts, or 255 for an automatic callout. In both 
+cases there follows a two-byte value giving the offset in the pattern to the
+start of the following item, and another two-byte item giving the length of the
+next item.
+
+
+Changing options
+----------------
+
+If any of the /i, /m, or /s options are changed within a pattern, an OP_OPT
+opcode is compiled, followed by one byte containing the new settings of these
+flags. If there are several alternatives, there is an occurrence of OP_OPT at
+the start of all those following the first options change, to set appropriate
+options for the start of the alternative. Immediately after the end of the
+group there is another such item to reset the flags to their previous values. A
+change of flag right at the very start of the pattern can be handled entirely
+at compile time, and so does not cause anything to be put into the compiled
+data.

 Basic Installation
 ==================
 
-   These are generic installation instructions that apply to systems that
-can run the `configure' shell script - Unix systems and any that imitate
-it. They are not specific to PCRE. There are PCRE-specific instructions
-for non-Unix systems in the file NON-UNIX-USE.

+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
 
    The `configure' shell script attempts to guess correct values for
 various system-dependent variables used during compilation.  It uses
 those values to create a `Makefile' in each directory of the package.
 It may also create one or more `.h' files containing system-dependent
 definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output

+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
 
    If you need to do unusual things to compile the package, please try
 to figure out how `configure' could check whether to do them, and mail
 diffs or instructions to the address given in the `README' so they can

 The simplest way to compile this package is:

 Compilers and Options
 =====================
 
    Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:

-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+   You can give `configure' initial values for configuration parameters

+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
 
 Compiling For Multiple Architectures
 ====================================
 
    You can compile the package for more than one kind of computer at the
 same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+own directory.  To do this, you can use GNU `make'.  `cd' to the
 directory where you want the object files and executables to go and run
 the `configure' script.  `configure' automatically checks for the
 source code in the directory that `configure' is in and in `..'.
 
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
 
 Installation Names
 ==================
 
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the

+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+

 Specifying the System Type
 ==========================
 
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints

-Operation Controls
+Defining Variables
 ==================
 
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).

+an Autoconf bug.  Until the bug is fixed you can use this workaround:

+`configure' Invocation
+======================
+
    `configure' recognizes the following options to control how it
 operates.
 
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for

+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'

 News about PCRE releases
 ------------------------
 
+Release 7.9 11-Apr-09
+---------------------
+
+Mostly bugfixes and tidies with just a couple of minor functional additions.
+
+
+Release 7.8 05-Sep-08
+---------------------
+
+More bug fixes, plus a performance improvement in Unicode character property
+lookup.
+
+
+Release 7.7 07-May-08
+---------------------
+
+This is once again mainly a bug-fix release, but there are a couple of new
+features.
+
+
+Release 7.6 28-Jan-08
+---------------------
+
+The main reason for having this release so soon after 7.5 is because it fixes a
+potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In
+addition, the CMake configuration files have been brought up to date.
+
+
+Release 7.5 10-Jan-08
+---------------------
+
+This is mainly a bug-fix release. However the ability to link pcregrep with
+libz or libbz2 and the ability to link pcretest with libreadline have been
+added. Also the --line-offsets and --file-offsets options were added to
+pcregrep.
+
+
+Release 7.4 21-Sep-07
+---------------------
+
+The only change of specification is the addition of options to control whether
+\R matches any Unicode line ending (the default) or just CR, LF, and CRLF.
+Otherwise, the changes are bug fixes and a refactoring to reduce the number of
+relocations needed in a shared library. There have also been some documentation
+updates, in particular, some more information about using CMake to build PCRE
+has been added to the NON-UNIX-USE file.
+
+
+Release 7.3 28-Aug-07
+---------------------
+
+Most changes are bug fixes. Some that are not:
+
+1. There is some support for Perl 5.10's experimental "backtracking control
+   verbs" such as (*PRUNE).
+
+2. UTF-8 checking is now as per RFC 3629 instead of RFC 2279; this is more
+   restrictive in the strings it accepts.
+
+3. Checking for potential integer overflow has been made more dynamic, and as a
+   consequence there is no longer a hard limit on the size of a subpattern that
+   has a limited repeat count.
+
+4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec()
+   no longer advance by two characters instead of one when an unanchored match
+   fails at CRLF if there are explicit CR or LF matches within the pattern.
+   This gets rid of some anomalous effects that previously occurred.
+
+5. Some PCRE-specific settings for varying the newline options at the start of
+   a pattern have been added.
+
+
+Release 7.2 19-Jun-07
+---------------------
+
+WARNING: saved patterns that were compiled by earlier versions of PCRE must be
+recompiled for use with 7.2 (necessitated by the addition of \K, \h, \H, \v,
+and \V).
+
+Correction to the notes for 7.1: the note about shared libraries for Windows is
+wrong. Previously, three libraries were built, but each could function
+independently. For example, the pcreposix library also included all the
+functions from the basic pcre library. The change is that the three libraries
+are no longer independent. They are like the Unix libraries. To use the
+pcreposix functions, for example, you need to link with both the pcreposix and
+the basic pcre library.
+
+Some more features from Perl 5.10 have been added:
+
+  (?-n) and (?+n) relative references for recursion and subroutines.
+
+  (?(-n) and (?(+n) relative references as conditions.
+
+  \k{name} and \g{name} are synonyms for \k<name>.
+
+  \K to reset the start of the matched string; for example, (foo)\Kbar
+  matches bar preceded by foo, but only sets bar as the matched string.
+
+  (?| introduces a group where the capturing parentheses in each alternative
+  start from the same number; for example, (?|(abc)|(xyz)) sets capturing
+  parentheses number 1 in both cases.
+
+  \h, \H, \v, \V match horizontal and vertical whitespace, respectively.
+
+
+Release 7.1 24-Apr-07
+---------------------
+
+There is only one new feature in this release: a linebreak setting of
+PCRE_NEWLINE_ANYCRLF. It is a cut-down version of PCRE_NEWLINE_ANY, which
+recognizes only CRLF, CR, and LF as linebreaks.
+
+A few bugs are fixed (see ChangeLog for details), but the major change is a
+complete re-implementation of the build system. This now has full Autotools
+support and so is now "standard" in some sense. It should help with compiling
+PCRE in a wide variety of environments.
+
+NOTE: when building shared libraries for Windows, three dlls are now built,
+called libpcre, libpcreposix, and libpcrecpp. Previously, everything was
+included in a single dll.
+
+Another important change is that the dftables auxiliary program is no longer
+compiled and run at "make" time by default. Instead, a default set of character
+tables (assuming ASCII coding) is used. If you want to use dftables to generate
+the character tables as previously, add --enable-rebuild-chartables to the
+"configure" command. You must do this if you are compiling PCRE to run on a
+system that uses EBCDIC code.
+
+There is a discussion about character tables in the README file. The default is
+not to use dftables so that that there is no problem when cross-compiling.
+
+
+Release 7.0 19-Dec-06
+---------------------
+
+This release has a new major number because there have been some internal
+upheavals to facilitate the addition of new optimizations and other facilities,
+and to make subsequent maintenance and extension easier. Compilation is likely
+to be a bit slower, but there should be no major effect on runtime performance.
+Previously compiled patterns are NOT upwards compatible with this release. If
+you have saved compiled patterns from a previous release, you will have to
+re-compile them. Important changes that are visible to users are:
+
+1. The Unicode property tables have been updated to Unicode 5.0.0, which adds
+   some more scripts.
+
+2. The option PCRE_NEWLINE_ANY causes PCRE to recognize any Unicode newline
+   sequence as a newline.
+
+3. The \R escape matches a single Unicode newline sequence as a single unit.
+
+4. New features that will appear in Perl 5.10 are now in PCRE. These include
+   alternative Perl syntax for named parentheses, and Perl syntax for
+   recursion.
+
+5. The C++ wrapper interface has been extended by the addition of a
+   QuoteMeta function and the ability to allow copy construction and
+   assignment.
+
+For a complete list of changes, see the ChangeLog file.

+GENERAL
+
+I (Philip Hazel) have no experience of Windows or VMS sytems and how their
+libraries work. The items in the PCRE distribution and Makefile that relate to
+anything other than Unix-like systems are untested by me.
+
+There are some other comments and files (including some documentation in CHM
+format) in the Contrib directory on the FTP site:
 
-If you want to compile PCRE for a non-Unix system (or perhaps, more strictly,
-for a system that does not support "configure" and "make" files), note that
-the basic PCRE library consists entirely of code written in Standard C, and so
-should compile successfully on any system that has a Standard C compiler and
-library. The C++ wrapper functions are a separate issue (see below).
-
-
-GENERIC INSTRUCTIONS FOR THE C LIBRARY
-
-The following are generic comments about building PCRE. The interspersed
-indented commands are suggestions from Mark Tetrode as to which commands you
-might use on a Windows system to build a static library.
-
-(1) Copy or rename the file config.in as config.h, and change the macros that
-define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
-Unfortunately, because of the way Unix autoconf works, the default setting has
-to be 0. You may also want to make changes to other macros in config.h. In
-particular, if you want to force a specific value for newline, you can define
-the NEWLINE macro. The default is to use '\n', thereby using whatever value
-your compiler gives to '\n'.
-
-  rem Mark Tetrode's commands
-  copy config.in config.h
-  rem Use write, because notepad cannot handle UNIX files. Change values.
-  write config.h
-
-(2) Compile dftables.c as a stand-alone program, and then run it with
-the single argument "pcre_chartables.c". This generates a set of standard
-character tables and writes them to that file.
-
-  rem Mark Tetrode's commands
-  rem Compile & run
-  cl -DSUPPORT_UTF8 -DSUPPORT_UCP dftables.c
-  dftables.exe pcre_chartables.c
-
-(3) Compile the following source files:
-
-  pcre_chartables.c
-  pcre_compile.c
-  pcre_config.c
-  pcre_dfa_exec.c
-  pcre_exec.c
-  pcre_fullinfo.c
-  pcre_get.c
-  pcre_globals.c
-  pcre_info.c
-  pcre_maketables.c
-  pcre_ord2utf8.c
-  pcre_refcount.c
-  pcre_study.c
-  pcre_tables.c
-  pcre_try_flipped.c
-  pcre_ucp_searchfuncs.c
-  pcre_valid_utf8.c
-  pcre_version.c
-  pcre_xclass.c
-
-and link them all together into an object library in whichever form your system
-keeps such libraries. This is the pcre C library. If your system has static and
-shared libraries, you may have to do this once for each type.
-
-  rem These comments are out-of-date, referring to a previous release which
-  rem had fewer source files. Replace with the file names from above.
-  rem Mark Tetrode's commands, for a static library
-  rem Compile & lib
-  cl -DSUPPORT_UTF8 -DSUPPORT_UCP -DPOSIX_MALLOC_THRESHOLD=10 /c maketables.c get.c study.c pcre.c
-  lib /OUT:pcre.lib maketables.obj get.obj study.obj pcre.obj
-
-(4) Similarly, compile pcreposix.c and link it (on its own) as the pcreposix
-library.
-
-  rem Mark Tetrode's commands, for a static library
-  rem Compile & lib
-  cl -DSUPPORT_UTF8 -DSUPPORT_UCP -DPOSIX_MALLOC_THRESHOLD=10 /c pcreposix.c
-  lib /OUT:pcreposix.lib pcreposix.obj
-
-(5) Compile the test program pcretest.c. This needs the functions in the
-pcre and pcreposix libraries when linking.
-
-  rem Mark Tetrode's commands
-  rem compile & link
-  cl /F0x400000 pcretest.c pcre.lib pcreposix.lib
-
-(6) Run pcretest on the testinput files in the testdata directory, and check
-that the output matches the corresponding testoutput files. You must use the
--i option when checking testinput2. Note that the supplied files are in Unix
-format, with just LF characters as line terminators. You may need to edit them
-to change this if your system uses a different convention.
-
-  rem Mark Tetrode's commands
-  pcretest testdata\testinput1 testdata\myoutput1
-  windiff testdata\testoutput1 testdata\myoutput1
-  pcretest -i testdata\testinput2 testdata\myoutput2

-wrote those comments. The test the new pcre_dfa_exec() function.
+If you want to compile PCRE for a non-Unix system (especially for a system that
+does not support "configure" and "make" files), note that the basic PCRE
+library consists entirely of code written in Standard C, and so should compile
+successfully on any system that has a Standard C compiler and library. The C++
+wrapper functions are a separate issue (see below).
+
+The PCRE distribution includes a "configure" file for use by the Configure/Make
+build system, as found in many Unix-like environments. There is also support
+support for CMake, which some users prefer, in particular in Windows
+environments. There are some instructions for CMake under Windows in the
+section entitled "Building PCRE with CMake" below. CMake can also be used to
+build PCRE in Unix-like systems.
+
+
+GENERIC INSTRUCTIONS FOR THE PCRE C LIBRARY
+
+The following are generic comments about building the PCRE C library "by hand".
+
+ (1) Copy or rename the file config.h.generic as config.h, and edit the macro
+     settings that it contains to whatever is appropriate for your environment.
+     In particular, if you want to force a specific value for newline, you can
+     define the NEWLINE macro. When you compile any of the PCRE modules, you
+     must specify -DHAVE_CONFIG_H to your compiler so that config.h is included
+     in the sources.
+
+     An alternative approach is not to edit config.h, but to use -D on the
+     compiler command line to make any changes that you need to the
+     configuration options. In this case -DHAVE_CONFIG_H must not be set.
+
+     NOTE: There have been occasions when the way in which certain parameters
+     in config.h are used has changed between releases. (In the configure/make
+     world, this is handled automatically.) When upgrading to a new release,
+     you are strongly advised to review config.h.generic before re-using what
+     you had previously.
+
+ (2) Copy or rename the file pcre.h.generic as pcre.h.
+
+ (3) EITHER:
+       Copy or rename file pcre_chartables.c.dist as pcre_chartables.c.
+
+     OR:
+       Compile dftables.c as a stand-alone program (using -DHAVE_CONFIG_H if
+       you have set up config.h), and then run it with the single argument
+       "pcre_chartables.c". This generates a set of standard character tables
+       and writes them to that file. The tables are generated using the default
+       C locale for your system. If you want to use a locale that is specified
+       by LC_xxx environment variables, add the -L option to the dftables
+       command. You must use this method if you are building on a system that
+       uses EBCDIC code.
+
+     The tables in pcre_chartables.c are defaults. The caller of PCRE can
+     specify alternative tables at run time.
+
+ (4) Ensure that you have the following header files:
+
+       pcre_internal.h
+       ucp.h
+
+ (5) Also ensure that you have the following file, which is #included as source
+     when building a debugging version of PCRE, and is also used by pcretest.
+
+       pcre_printint.src
+
+ (6) Compile the following source files, setting -DHAVE_CONFIG_H as a compiler
+     option if you have set up config.h with your configuration, or else use
+     other -D settings to change the configuration as required.
+
+       pcre_chartables.c

+     Make sure that you include -I. in the compiler command (or equivalent for
+     an unusual compiler) so that all included PCRE header files are first
+     sought in the current directory. Otherwise you run the risk of picking up
+     a previously-installed file from somewhere else.
+
+ (7) Now link all the compiled code into an object library in whichever form
+     your system keeps such libraries. This is the basic PCRE C library. If
+     your system has static and shared libraries, you may have to do this once
+     for each type.
+
+ (8) Similarly, compile pcreposix.c (remembering -DHAVE_CONFIG_H if necessary)
+     and link the result (on its own) as the pcreposix library.
+
+ (9) Compile the test program pcretest.c (again, don't forget -DHAVE_CONFIG_H).
+     This needs the functions in the pcre and pcreposix libraries when linking.
+     It also needs the pcre_printint.src source file, which it #includes.
+
+(10) Run pcretest on the testinput files in the testdata directory, and check
+     that the output matches the corresponding testoutput files. Note that the
+     supplied files are in Unix format, with just LF characters as line
+     terminators. You may need to edit them to change this if your system uses
+     a different convention. If you are using Windows, you probably should use
+     the wintestinput3 file instead of testinput3 (and the corresponding output
+     file). This is a locale test; wintestinput3 sets the locale to "french"
+     rather than "fr_FR", and there some minor output differences.

-uses only the basic PCRE library.

-
-Some help in building a Win32 DLL of PCRE in GnuWin32 environments was
-contributed by Paul Sokolovsky. These environments are Mingw32
-(http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin
-(http://sourceware.cygnus.com/cygwin/). Paul comments:
-
-  For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
-  pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically
-  linked pgrep and pcretest. If you have /bin/sh, run RunTest (three
-  main test go ok, locale not supported).
-
-Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox
-<sailorFred at yahoo.com>, who comments as follows:
-
-  If you are using the PCRE DLL, the normal Unix style configure && make &&
-  make check && make install should just work[*]. If you want to statically
-  link against the .a file, you must define PCRE_STATIC before including
-  pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be
-  declared __declspec(dllimport), with hilarious results.  See the configure.in
-  and pcretest.c for how it is done for the static test.
-
-  Also, there will only be a libpcre.la, not a libpcreposix.la, as you
-  would expect from the Unix version. The single DLL includes the pcreposix
-  interface.
-
-[*] But note that the supplied test files are in Unix format, with just LF
-characters as line terminators. You will have to edit them to change to CR LF
-terminators.
+BUILDING FOR VIRTUAL PASCAL
 
 A script for building PCRE using Borland's C++ compiler for use with VPASCAL
-was contributed by Alexander Tokarev. It is called makevp.bat.
+was contributed by Alexander Tokarev. Stefan Weber updated the script and added
+additional files. The following files in the distribution are for building PCRE
+for use with VP/Borland: makevp_c.txt, makevp_l.txt, makevp.bat, pcregexp.pas.
 
-These are some further comments about Win32 builds from Mark Evans. They
-were contributed before Fred Cox's changes were made, so it is possible that
-they may no longer be relevant.
-
-"The documentation for Win32 builds is a bit shy.  Under MSVC6 I
-followed their instructions to the letter, but there were still
-some things missing.
-
-(1) Must #define STATIC for entire project if linking statically.
-    (I see no reason to use DLLs for code this compact.)  This of
-    course is a project setting in MSVC under Preprocessor.
-
-(2) Missing some #ifdefs relating to the function pointers
-    pcre_malloc and pcre_free.  See my solution below.  (The stubs
-    may not be mandatory but they made me feel better.)"
 
-=========================
-#ifdef _WIN32
-#include <malloc.h>
+STACK SIZE IN WINDOWS ENVIRONMENTS
 
-void* malloc_stub(size_t N)
-{ return malloc(N); }
-void free_stub(void* p)
-{ free(p); }
-void *(*pcre_malloc)(size_t) = &malloc_stub;
-void  (*pcre_free)(void *) = &free_stub;
+The default processor stack size of 1Mb in some Windows environments is too
+small for matching patterns that need much recursion. In particular, test 2 may
+fail because of this. Normally, running out of stack causes a crash, but there
+have been cases where the test program has just died silently. See your linker
+documentation for how to increase stack size if you experience problems. The
+Linux default of 8Mb is a reasonable choice for the stack, though even that can
+be too small for some pattern/subject combinations.
 
-#else
+PCRE has a compile configuration option to disable the use of stack for
+recursion so that heap is used instead. However, pattern matching is
+significantly slower when this is done. There is more about stack usage in the
+"pcrestack" documentation.
 
-void *(*pcre_malloc)(size_t) = malloc;
-void  (*pcre_free)(void *) = free;
 
-#endif
-=========================
+LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
+
+If you want to statically link a program against a PCRE library in the form of
+a non-dll .a file, you must define PCRE_STATIC before including pcre.h,
+otherwise the pcre_malloc() and pcre_free() exported functions will be declared
+__declspec(dllimport), with unwanted results.
+
+
+CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
+
+It is possible to compile programs to use different calling conventions using
+MSVC. Search the web for "calling conventions" for more information. To make it
+easier to change the calling convention for the exported functions in the
+PCRE library, the macro PCRE_CALL_CONVENTION is present in all the external
+definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
+not set, it defaults to empty; the default calling convention is then used
+(which is what is wanted most of the time).
+
+
+COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE WITH CMAKE" below)
+
+There are two ways of building PCRE using the "configure, make, make install"
+paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
+the same thing; they are completely different from each other. There is also
+support for building using CMake, which some users find a more straightforward
+way of building PCRE under Windows. However, the tests are not run
+automatically when CMake is used.
+
+The MinGW home page (http://www.mingw.org/) says this:
+
+  MinGW: A collection of freely available and freely distributable Windows
+  specific header files and import libraries combined with GNU toolsets that
+  allow one to produce native Windows programs that do not rely on any
+  3rd-party C runtime DLLs.
+
+The Cygwin home page (http://www.cygwin.com/) says this:
+
+  Cygwin is a Linux-like environment for Windows. It consists of two parts:
+
+  . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
+    substantial Linux API functionality
+
+  . A collection of tools which provide Linux look and feel.
+
+  The Cygwin DLL currently works with all recent, commercially released x86 32
+  bit and 64 bit versions of Windows, with the exception of Windows CE.
+
+On both MinGW and Cygwin, PCRE should build correctly using:
+
+  ./configure && make && make install
+
+This should create two libraries called libpcre and libpcreposix, and, if you
+have enabled building the C++ wrapper, a third one called libpcrecpp. These are
+independent libraries: when you like with libpcreposix or libpcrecpp you must
+also link with libpcre, which contains the basic functions. (Some earlier
+releases of PCRE included the basic libpcre functions in libpcreposix. This no
+longer happens.)
+
+A user submitted a special-purpose patch that makes it easy to create
+"pcre.dll" under mingw32 using the "msys" environment. It provides "pcre.dll"
+as a special target. If you use this target, no other files are built, and in
+particular, the pcretest and pcregrep programs are not built. An example of how
+this might be used is:
+
+  ./configure --enable-utf --disable-cpp CFLAGS="-03 -s"; make pcre.dll
+
+Using Cygwin's compiler generates libraries and executables that depend on
+cygwin1.dll. If a library that is generated this way is distributed,
+cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
+licence, this forces not only PCRE to be under the GPL, but also the entire
+application. A distributor who wants to keep their own code proprietary must
+purchase an appropriate Cygwin licence.
+
+MinGW has no such restrictions. The MinGW compiler generates a library or
+executable that can run standalone on Windows without any third party dll or
+licensing issues.
+
+But there is more complication:
+
+If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
+to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
+front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
+gcc and MinGW's gcc). So, a user can:
+
+. Build native binaries by using MinGW or by getting Cygwin and using
+  -mno-cygwin.
+
+. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
+  compiler flags.
+
+The test files that are supplied with PCRE are in Unix format, with LF
+characters as line terminators. It may be necessary to change the line
+terminators in order to get some of the tests to work. We hope to improve
+things in this area in future.
+
+
+BUILDING PCRE ON WINDOWS WITH CMAKE
+
+CMake is an alternative build facility that can be used instead of the
+traditional Unix "configure". CMake version 2.4.7 supports Borland makefiles,
+MinGW makefiles, MSYS makefiles, NMake makefiles, UNIX makefiles, Visual Studio
+6, Visual Studio 7, Visual Studio 8, and Watcom W8. The following instructions
+were contributed by a PCRE user.
+
+1.  Download CMake 2.4.7 or above from http://www.cmake.org/, install and ensure
+    that cmake\bin is on your path.
+
+2.  Unzip (retaining folder structure) the PCRE source tree into a source
+    directory such as C:\pcre.
+
+3.  Create a new, empty build directory: C:\pcre\build\
+
+4.  Run CMakeSetup from the Shell envirornment of your build tool, e.g., Msys
+    for Msys/MinGW or Visual Studio Command Prompt for VC/VC++
+
+5.  Enter C:\pcre\pcre-xx and C:\pcre\build for the source and build
+    directories, respectively
+
+6.  Hit the "Configure" button.
+
+7.  Select the particular IDE / build tool that you are using (Visual Studio,
+    MSYS makefiles, MinGW makefiles, etc.)
+
+8.  The GUI will then list several configuration options. This is where you can
+    enable UTF-8 support, etc.
+
+9.  Hit "Configure" again. The adjacent "OK" button should now be active.
+
+10. Hit "OK".
+
+11. The build directory should now contain a usable build system, be it a
+    solution file for Visual Studio, makefiles for MinGW, etc.
+
+
+USE OF RELATIVE PATHS WITH CMAKE ON WINDOWS
+
+A PCRE user comments as follows:
+
+I thought that others may want to know the current state of
+CMAKE_USE_RELATIVE_PATHS support on Windows.
+
+Here it is:
+-- AdditionalIncludeDirectories is only partially modified (only the
+first path - see below)
+-- Only some of the contained file paths are modified - shown below for
+pcre.vcproj
+-- It properly modifies
+
+I am sure CMake people can fix that if they want to. Until then one will
+need to replace existing absolute paths in project files with relative
+paths manually (e.g. from VS) - relative to project file location. I did
+just that before being told to try CMAKE_USE_RELATIVE_PATHS. Not a big
+deal.
+
+AdditionalIncludeDirectories="E:\builds\pcre\build;E:\builds\pcre\pcre-7.5;"
+AdditionalIncludeDirectories=".;E:\builds\pcre\pcre-7.5;"
+
+RelativePath="pcre.h">
+RelativePath="pcre_chartables.c">
+RelativePath="pcre_chartables.c.rule">
+
+
+TESTING WITH RUNTEST.BAT
+
+1. Copy RunTest.bat into the directory where pcretest.exe has been created.
+
+2. Edit RunTest.bat and insert a line that indentifies the relative location of
+   the pcre source, e.g.:
+
+   set srcdir=..\pcre-7.4-RC3
+
+3. Run RunTest.bat from a command shell environment. Test outputs will
+   automatically be compared to expected results, and discrepancies will
+   identified in the console output.
+
+4. To test pcrecpp, run pcrecpp_unittest.exe, pcre_stringpiece_unittest.exe and
+   pcre_scanner_unittest.exe.
+
+
+BUILDING UNDER WINDOWS WITH BCC5.5
+
+Michael Roy sent these comments about building PCRE under Windows with BCC5.5:
+
+  Some of the core BCC libraries have a version of PCRE from 1998 built in,
+  which can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a
+  version mismatch. I'm including an easy workaround below, if you'd like to
+  include it in the non-unix instructions:
+
+  When linking a project with BCC5.5, pcre.lib must be included before any of
+  the libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command
+  line.
+
+
+BUILDING UNDER WINDOWS CE WITH VISUAL STUDIO 200x
+
+Vincent Richomme sent a zip archive of files to help with this process. They
+can be found in the file "pcre-vsbuild.zip" in the Contrib directory of the FTP
+site.

 The PCRE APIs
 -------------
 
-PCRE is written in C, and it has its own API. The distribution now includes a
-set of C++ wrapper functions, courtesy of Google Inc. (see the pcrecpp man page
-for details).
-
-Also included are a set of C wrapper functions that are based on the POSIX
-API. These end up in the library called libpcreposix. Note that this just
-provides a POSIX calling interface to PCRE: the regular expressions themselves
-still follow Perl syntax and semantics. The header file for the POSIX-style
-functions is called pcreposix.h. The official POSIX name is regex.h, but I
-didn't want to risk possible problems with existing files of that name by
-distributing it that way. To use it with an existing program that uses the
-POSIX API, it will have to be renamed or pointed at by a link.

-are less than 256. The final argument of the pcre_compile() function is a
-pointer to a block of memory containing the concatenated tables. A call to
-pcre_maketables() can be used to generate a set of tables in the current
-locale. If the final argument for pcre_compile() is passed as NULL, a set of
-default tables that is built into the binary is used.
-
-The source file called chartables.c contains the default set of tables. This is
-not supplied in the distribution, but is built by the program dftables
-(compiled from dftables.c), which uses the ANSI C character handling functions
-such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table
-sources. This means that the default C locale which is set for your system will
-control the contents of these default tables. You can change the default tables
-by editing chartables.c and then re-building PCRE. If you do this, you should
-probably also edit Makefile to ensure that the file doesn't ever get
-re-generated.
+For speed, PCRE uses four tables for manipulating and identifying characters
+whose code point values are less than 256. The final argument of the
+pcre_compile() function is a pointer to a block of memory containing the
+concatenated tables. A call to pcre_maketables() can be used to generate a set
+of tables in the current locale. If the final argument for pcre_compile() is
+passed as NULL, a set of default tables that is built into the binary is used.
+
+The source file called pcre_chartables.c contains the default set of tables. By
+default, this is created as a copy of pcre_chartables.c.dist, which contains
+tables for ASCII coding. However, if --enable-rebuild-chartables is specified
+for ./configure, a different version of pcre_chartables.c is built by the
+program dftables (compiled from dftables.c), which uses the ANSI C character
+handling functions such as isalnum(), isalpha(), isupper(), islower(), etc. to
+build the table sources. This means that the default C locale which is set for
+your system will control the contents of these default tables. You can change
+the default tables by editing pcre_chartables.c and then re-building PCRE. If
+you do this, you should take care to ensure that the file does not get
+automatically re-generated. The best way to do this is to move
+pcre_chartables.c.dist out of the way and replace it with your customized
+tables.
+
+When the dftables program is run as a result of --enable-rebuild-chartables,
+it uses the default C locale that is set on your system. It does not pay
+attention to the LC_xxx environment variables. In other words, it uses the
+system's default locale rather than whatever the compiling user happens to have
+set. If you really do want to build a source set of character tables in a
+locale that is specified by the LC_xxx variables, you can run the dftables
+program by hand with the -L option. For example:
+
+  ./dftables -L pcre_chartables.c.special
 
 The first two 256-byte tables provide lower casing and case flipping functions,
 respectively. The next table consists of three 32-byte bit maps which identify
 digits, "word" characters, and white space, respectively. These are used when
-building 32-byte bit maps that represent character classes.

 The final 256-byte table has bits indicating various character types, as

+macro definitions the way you need them. You must then add -DHAVE_CONFIG_H to
+all of your compile commands, so that config.h is included at the start of
+every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H.
+
+PCRE uses memmove() if HAVE_MEMMOVE is set to 1; otherwise it uses bcopy() if
+HAVE_BCOPY is set to 1. If your system has neither bcopy() nor memmove(), set
+them both to 0; an emulation function will be used. */])

+Validity of UTF-8 strings
+</b><br>
+<P>
+When you set the PCRE_UTF8 flag, the strings passed as patterns and subjects
+are (by default) checked for validity on entry to the relevant functions. From
+release 7.3 of PCRE, the check is according the rules of RFC 3629, which are
+themselves derived from the Unicode specification. Earlier releases of PCRE
+followed the rules of RFC 2279, which allows the full range of 31-bit values (0
+to 0x7FFFFFFF). The current check allows only values in the range U+0 to
+U+10FFFF, excluding U+D800 to U+DFFF.
+</P>
+<P>
+The excluded code points are the "Low Surrogate Area" of Unicode, of which the
+Unicode Standard says this: "The Low Surrogate Area does not contain any
+character assignments, consequently no character code charts or namelists are
+provided for this area. Surrogates are reserved for use with UTF-16 and then
+must be used in pairs." The code points that are encoded by UTF-16 pairs are
+available as independent code points in the UTF-8 encoding. (In other words,
+the whole surrogate thing is a fudge for UTF-16 which unfortunately messes up
+UTF-8.)
+</P>
+<P>
+If an invalid UTF-8 string is passed to PCRE, an error return
+(PCRE_ERROR_BADUTF8) is given. In some situations, you may already know that
+your strings are valid, and therefore want to skip these checks in order to
+improve performance. If you set the PCRE_NO_UTF8_CHECK flag at compile time or
+at run time, PCRE assumes that the pattern or subject it is given
+(respectively) contains only valid UTF-8 codes. In this case, it does not
+diagnose an invalid UTF-8 string.
+</P>
+<P>
+If you pass an invalid UTF-8 string when PCRE_NO_UTF8_CHECK is set, what
+happens depends on why the string is invalid. If the string conforms to the
+"old" definition of UTF-8 (RFC 2279), it is processed as a string of characters
+in the range 0 to 0x7FFFFFFF. In other words, apart from the initial validity
+test, PCRE (when in UTF-8 mode) handles strings according to the more liberal
+rules of RFC 2279. However, if the string does not even conform to RFC 2279,
+the result is undefined. Your program may crash.
+</P>
+<P>
+If you want to process strings of values in the full range 0 to 0x7FFFFFFF,
+encoded in a UTF-8-like manner as per the old RFC, you can set
+PCRE_NO_UTF8_CHECK to bypass the more restrictive test. However, in this

+PCRE supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The Unicode newline sequences are the three just
+mentioned, plus the single characters VT (vertical tab, U+000B), FF (formfeed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).

+Each of the first three conventions is used by at least one operating system as
+its standard newline sequence. When PCRE is built, a default can be specified.
+The default default is LF, which is the Unix standard. When PCRE is run, the
+default can be overridden, either when a pattern is compiled, or when it is

+<P>
+At compile time, the newline convention can be specified by the <i>options</i>

+start of the pattern itself; this overrides any other settings. See the
+<a href="pcrepattern.html"><b>pcrepattern</b></a>

 In the PCRE documentation the word "newline" is used to mean "the character or

+Perl 5.10 introduced a feature whereby each alternative in a subpattern uses
+the same numbers for its capturing parentheses. Such a subpattern starts with
+(?| and is itself a non-capturing subpattern. For example, consider this
+pattern:
+<pre>
+  (?|(Sat)ur|(Sun))day
+</pre>
+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+buffers that follow the subpattern start after the highest number used in any
+branch. The following example is taken from the Perl documentation.
+The numbers underneath show in which buffer the captured content will be
+stored.

+<P>
+The new verbs make use of what was previously invalid syntax: an opening

+This verb causes the match to end successfully, skipping the remainder of the

+immediately. PCRE differs from Perl in what happens if the (*ACCEPT) is inside
+capturing parentheses. In Perl, the data so far is captured: in PCRE no data is
+captured. For example:
+<pre>
+  A(A|B(*ACCEPT)|C)D

+This matches "AB", "AAD", or "ACD", but when it matches "AB", no data is
+captured.

+  (*FAIL) or (*F)
+</pre>
+This verb causes the match to fail, forcing backtracking to occur. It is
+equivalent to (?!) but easier to read. The Perl documentation notes that it is
+probably useful only when combined with (?{}) or (??{}). Those are, of course,
+Perl features that are not present in PCRE. The nearest equivalent is the
+callout feature, as for example in this pattern:
+<pre>

+  (*COMMIT)
+</pre>
+This verb causes the whole match to fail outright if the rest of the pattern
+does not match. Even if the pattern is unanchored, no further attempts to find
+a match by advancing the start point take place. Once (*COMMIT) has been
+passed, <b>pcre_exec()</b> is committed to finding a match at the current
+starting point, or not at all. For example:
+<pre>
+  a+(*COMMIT)b
+</pre>
+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish."
+<pre>
+  (*PRUNE)
+</pre>
+This verb causes the match to fail at the current position if the rest of the
+pattern does not match. If the pattern is unanchored, the normal "bumpalong"
+advance to the next starting character then happens. Backtracking can occur as
+usual to the left of (*PRUNE), or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE).
+In simple cases, the use of (*PRUNE) is just an alternative to an atomic

+be expressed in any other way.
+<pre>
+  (*SKIP)
+</pre>
+This verb is like (*PRUNE), except that if the pattern is unanchored, the
+"bumpalong" advance is not to the next character, but to the position in the
+subject where (*SKIP) was encountered. (*SKIP) signifies that whatever text
+was matched leading up to it cannot be part of a successful match. Consider:
+<pre>
+  a+(*SKIP)b
+</pre>
+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifer does not have the same
+effect in this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+<pre>
+  (*THEN)
+</pre>
+This verb causes a skip to the next alternation if the rest of the pattern does
+not match. That is, it cancels pending backtracking, but only within the
+current alternation. Its name comes from the observation that it can be used
+for a pattern-based if-then-else block:
+<pre>
+  ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+</pre>
+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If (*THEN)
+is used outside of any alternation, it acts exactly like (*PRUNE).

 PCRE PERFORMANCE
 </b><br>
 <P>
-Certain items that may appear in regular expression patterns are more efficient
+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+</P>
+<br><b>
+MEMORY USAGE
+</b><br>
+<P>
+Patterns are compiled by PCRE into a reasonably efficient byte code, so that
+most simple patterns do not use much memory. However, there is one case where
+memory usage can be unexpectedly large. When a parenthesized subpattern has a
+quantifier with a minimum greater than 1 and/or a limited maximum, the whole
+subpattern is repeated in the compiled code. For example, the pattern
+<pre>
+  (abc|def){2,4}
+</pre>
+is compiled as if it were
+<pre>
+  (abc|def)(abc|def)((abc|def)(abc|def)?)?
+</pre>
+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+</P>
+<P>
+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+<pre>
+  ((ab){1,1000}c){1,3}
+</pre>
+uses 51K bytes when compiled. When PCRE is compiled with its default internal
+pointer size of two bytes, the size limit on a compiled pattern is 64K, and
+this is reached with the above pattern if the outer repetition is increased
+from 3 to 4. PCRE can be compiled to use larger internal pointers and thus
+handle larger compiled patterns, but it is better to try to rewrite your
+pattern to use less memory if you can.
+</P>
+<P>
+One way of reducing the memory usage for such patterns is to make use of PCRE's
+<a href="pcrepattern.html#subpatternsassubroutines">"subroutine"</a>
+facility. Re-writing the above pattern as
+<pre>
+  ((ab)(?2){0,999}c)(?1){0,2}
+</pre>
+reduces the memory requirements to 18K, and indeed it remains under 20K even
+with the outer repetition increased to 100. However, this pattern is not
+exactly equivalent, because the "subroutine" calls are treated as
+<a href="pcrepattern.html#atomicgroup">atomic groups</a>
+into which there can be no backtracking if there is a subsequent matching
+failure. Therefore, PCRE cannot do this kind of rewriting automatically.
+Furthermore, there is a noticeable loss of speed when executing the modified
+pattern. Nevertheless, if the atomic grouping is not a problem and the loss of

+Compiling PCRE to use heap instead of stack
+</b><br>
+<P>
 In environments where stack memory is constrained, you might want to compile
 PCRE to use heap memory instead of stack for remembering back-up points. This
 makes it run a lot more slowly, however. Details of how to do this are given in
 the
 <a href="pcrebuild.html"><b>pcrebuild</b></a>
+documentation. When built in this way, instead of using the stack, PCRE obtains
+and frees memory by calling the functions that are pointed to by the
+<b>pcre_stack_malloc</b> and <b>pcre_stack_free</b> variables. By default, these
+point to <b>malloc()</b> and <b>free()</b>, but you can replace the pointers to
+cause PCRE to use your own functions. Since the block sizes are always the
+same, and are always freed in reverse order, it may be possible to implement
+customized memory handlers that are more efficient than the standard functions.
+</P>
+<br><b>
+Limiting PCRE's stack usage

+PCRE has an internal counter that can be used to limit the depth of recursion,
+and thus cause <b>pcre_exec()</b> to give an error code before it runs out of
+stack. By default, the limit is very large, and unlikely ever to operate. It
+can be changed when PCRE is built, and it can also be set when

        The  PCRE  library is a set of functions that implement regular expres-

+       When you set the PCRE_UTF8 flag, the strings  passed  as  patterns  and
+       subjects are (by default) checked for validity on entry to the relevant
+       functions. From release 7.3 of PCRE, the check is according  the  rules
+       of  RFC  3629, which are themselves derived from the Unicode specifica-
+       tion. Earlier releases of PCRE followed the rules of  RFC  2279,  which
+       allows  the  full range of 31-bit values (0 to 0x7FFFFFFF). The current
+       check allows only values in the range U+0 to U+10FFFF, excluding U+D800
+       to U+DFFF.
+
+       The  excluded  code  points are the "Low Surrogate Area" of Unicode, of
+       which the Unicode Standard says this: "The Low Surrogate Area does  not
+       contain  any  character  assignments,  consequently  no  character code
+       charts or namelists are provided for this area. Surrogates are reserved
+       for  use  with  UTF-16 and then must be used in pairs." The code points
+       that are encoded by UTF-16 pairs  are  available  as  independent  code
+       points  in  the  UTF-8  encoding.  (In other words, the whole surrogate
+       thing is a fudge for UTF-16 which unfortunately messes up UTF-8.)
+
+       If an  invalid  UTF-8  string  is  passed  to  PCRE,  an  error  return
+       (PCRE_ERROR_BADUTF8) is given. In some situations, you may already know

+
+         --enable-rebuild-chartables
+
+       to  the  configure  command, the distributed tables are no longer used.
+       Instead, a program called dftables is compiled and  run.  This  outputs
+       the source for new set of tables, created in the default locale of your
+       C runtime system. (This method of replacing the tables does not work if

+       have to do so "by hand".)

+
+       If you add

+         --enable-pcretest-libreadline
+
+       to  the  configure  command,  pcretest  is  linked with the libreadline
+       library, and when its input is from a terminal, it reads it  using  the
+       readline() function. This provides line-editing and history facilities.
+       Note that libreadline is GPL-licenced, so if you distribute a binary of
+       pcretest linked in this way, there may be licensing issues.
+
+       Setting  this  option  causes  the -lreadline option to be added to the
+       pcretest build. In many operating environments with  a  sytem-installed
+       libreadline this is sufficient. However, in some environments (e.g.  if
+       an unmodified distribution version of readline is in use),  some  extra
+       configuration  may  be necessary. The INSTALL file for libreadline says
+       this:
+
+         "Readline uses the termcap functions, but does not link with the
+         termcap or curses library itself, allowing applications which link
+         with readline the to choose an appropriate library."
+
+       If your environment has not been set up so that an appropriate  library
+       is automatically included, you may need to add something like
+
+         LIBS="-ncurses"
+
+       immediately before the configure command.

 NEWLINES
-       PCRE supports three different conventions for indicating line breaks in
-       strings: a single CR character, a single LF character, or the two-char-
-       acter  sequence  CRLF.  All  three  are used as "standard" by different
-       operating systems.  When PCRE is built, a default can be specified. The
-       default  default  is  LF, which is the Unix standard. When PCRE is run,
-       the default can be overridden, either when a pattern  is  compiled,  or
-       when it is matched.

+       PCRE  supports five different conventions for indicating line breaks in
+       strings: a single CR (carriage return) character, a  single  LF  (line-
+       feed) character, the two-character sequence CRLF, any of the three pre-
+       ceding, or any Unicode newline sequence. The Unicode newline  sequences
+       are  the  three just mentioned, plus the single characters VT (vertical
+       tab, U+000B), FF (formfeed, U+000C), NEL (next line, U+0085), LS  (line
+       separator, U+2028), and PS (paragraph separator, U+2029).
+
+       Each  of  the first three conventions is used by at least one operating
+       system as its standard newline sequence. When PCRE is built, a  default
+       can  be  specified.  The default default is LF, which is the Unix stan-
+       dard. When PCRE is run, the default can be overridden,  either  when  a
+       pattern is compiled, or when it is matched.
+
+       At compile time, the newline convention can be specified by the options
+       argument of pcre_compile(), or it can be specified by special  text  at
+       the start of the pattern itself; this overrides any other settings. See
+       the pcrepattern page for details of the special character sequences.

+
+       If this option is set, PCRE's behaviour is changed in some ways so that
+       it is compatible with JavaScript rather than Perl. The changes  are  as
+       follows:
+
+       (1)  A  lone  closing square bracket in a pattern causes a compile-time
+       error, because this is illegal in JavaScript (by default it is  treated
+       as a data character). Thus, the pattern AB]CD becomes illegal when this
+       option is set.
+
+       (2) At run time, a back reference to an unset subpattern group  matches
+       an  empty  string (by default this causes the current matching alterna-
+       tive to fail). A pattern such as (\1)(a) succeeds when this  option  is
+       set  (assuming  it can find an "a" in the subject), whereas it fails by
+       default, for Perl compatibility.

+
+       The newline setting in the  options  word  uses  three  bits  that  are

    How pcre_exec() returns captured substrings
 
-       In general, a pattern matches a certain portion of the subject, and  in
-       addition,  further  substrings  from  the  subject may be picked out by
-       parts of the pattern. Following the usage  in  Jeffrey  Friedl's  book,
-       this  is  called "capturing" in what follows, and the phrase "capturing
-       subpattern" is used for a fragment of a pattern that picks out  a  sub-
-       string.  PCRE  supports several other kinds of parenthesized subpattern
+       In  general, a pattern matches a certain portion of the subject, and in

+       subpattern"  is  used for a fragment of a pattern that picks out a sub-
+       string. PCRE supports several other kinds of  parenthesized  subpattern
        that do not cause substrings to be captured.
 
-       Captured substrings are returned to the caller via a vector of  integer
-       offsets  whose  address is passed in ovector. The number of elements in
-       the vector is passed in ovecsize, which must be a non-negative  number.
-       Note: this argument is NOT the size of ovector in bytes.
-
-       The  first  two-thirds of the vector is used to pass back captured sub-
-       strings, each substring using a pair of integers. The  remaining  third
-       of  the  vector is used as workspace by pcre_exec() while matching cap-
-       turing subpatterns, and is not available for passing back  information.
-       The  length passed in ovecsize should always be a multiple of three. If
+       Captured substrings are returned to the caller via a vector of integers
+       whose address is passed in ovector. The number of elements in the  vec-
+       tor  is  passed in ovecsize, which must be a non-negative number. Note:
+       this argument is NOT the size of ovector in bytes.
+
+       The first two-thirds of the vector is used to pass back  captured  sub-
+       strings,  each  substring using a pair of integers. The remaining third
+       of the vector is used as workspace by pcre_exec() while  matching  cap-
+       turing  subpatterns, and is not available for passing back information.
+       The number passed in ovecsize should always be a multiple of three.  If
        it is not, it is rounded down.
 
-       When a match is successful, information about  captured  substrings  is
-       returned  in  pairs  of integers, starting at the beginning of ovector,
-       and continuing up to two-thirds of its length at the  most.  The  first
-       element of a pair is set to the offset of the first character in a sub-
-       string, and the second is set to the  offset  of  the  first  character
-       after  the  end  of  a  substring. The first pair, ovector[0] and ovec-
-       tor[1], identify the portion of  the  subject  string  matched  by  the
-       entire  pattern.  The next pair is used for the first capturing subpat-
-       tern, and so on. The value returned by pcre_exec() is one more than the
-       highest numbered pair that has been set. For example, if two substrings
-       have been captured, the returned value is 3. If there are no  capturing
-       subpatterns,  the return value from a successful match is 1, indicating
-       that just the first pair of offsets has been set.
+       When  a  match  is successful, information about captured substrings is
+       returned in pairs of integers, starting at the  beginning  of  ovector,
+       and  continuing  up  to two-thirds of its length at the most. The first
+       element of each pair is set to the byte offset of the  first  character
+       in  a  substring, and the second is set to the byte offset of the first
+       character after the end of a substring. Note: these values  are  always
+       byte offsets, even in UTF-8 mode. They are not character counts.
+
+       The  first  pair  of  integers, ovector[0] and ovector[1], identify the
+       portion of the subject string matched by the entire pattern.  The  next
+       pair  is  used for the first capturing subpattern, and so on. The value
+       returned by pcre_exec() is one more than the highest numbered pair that
+       has  been  set.  For example, if two substrings have been captured, the
+       returned value is 3. If there are no capturing subpatterns, the  return
+       value from a successful match is 1, indicating that just the first pair
+       of offsets has been set.
 
        If a capturing subpattern is matched repeatedly, it is the last portion
        of the string that it matched that is returned.
 
        If  the vector is too small to hold all the captured substring offsets,
        it is used as far as possible (up to two-thirds of its length), and the
-       function  returns a value of zero. In particular, if the substring off-
-       sets are not of interest, pcre_exec() may be called with ovector passed
-       as  NULL  and  ovecsize  as zero. However, if the pattern contains back
-       references and the ovector is not big enough to  remember  the  related

 PCRE REGULAR EXPRESSION DETAILS
 
-       The  syntax  and semantics of the regular expressions supported by PCRE
-       are described below. Regular expressions are also described in the Perl
-       documentation  and  in  a  number  of books, some of which have copious
-       examples.  Jeffrey Friedl's "Mastering Regular Expressions",  published
-       by  O'Reilly, covers regular expressions in great detail. This descrip-

+       tax summary in the pcresyntax page. PCRE tries to match Perl syntax and
+       semantics as closely as it can. PCRE  also  supports  some  alternative
+       regular  expression  syntax (which does not conflict with the Perl syn-
+       tax) in order to provide some compatibility with regular expressions in

        The original operation of PCRE was on strings of  one-byte  characters.
        However,  there is now also support for UTF-8 character strings. To use
        this, you must build PCRE to  include  UTF-8  support,  and  then  call
-       pcre_compile()  with  the  PCRE_UTF8  option.  How this affects pattern
-       matching is mentioned in several places below. There is also a  summary
-       of  UTF-8  features  in  the  section on UTF-8 support in the main pcre
-       page.
+       pcre_compile()  with  the  PCRE_UTF8  option.  There  is also a special
+       sequence that can be given at the start of a pattern:
+
+         (*UTF8)
+
+       Starting a pattern with this sequence  is  equivalent  to  setting  the
+       PCRE_UTF8  option.  This  feature  is  not Perl-compatible. How setting
+       UTF-8 mode affects pattern matching  is  mentioned  in  several  places
+       below.  There  is  also  a  summary of UTF-8 features in the section on
+       UTF-8 support in the main pcre page.
 
        The remainder of this document discusses the  patterns  that  are  sup-
        ported  by  PCRE when its main matching function, pcre_exec(), is used.
        From  release  6.0,   PCRE   offers   a   second   matching   function,
        pcre_dfa_exec(),  which matches using a different algorithm that is not
-       Perl-compatible. The advantages and disadvantages  of  the  alternative
-       function, and how it differs from the normal function, are discussed in
-       the pcrematching page.

+       alternative function, and how it differs from the normal function,  are
+       discussed in the pcrematching page.
+
+
+NEWLINE CONVENTIONS
+
+       PCRE  supports five different conventions for indicating line breaks in
+       strings: a single CR (carriage return) character, a  single  LF  (line-
+       feed) character, the two-character sequence CRLF, any of the three pre-
+       ceding, or any Unicode newline sequence. The pcreapi page  has  further
+       discussion  about newlines, and shows how to set the newline convention
+       in the options arguments for the compiling and matching functions.
+
+       It is also possible to specify a newline convention by starting a  pat-
+       tern string with one of the following five sequences:
+
+         (*CR)        carriage return
+         (*LF)        linefeed
+         (*CRLF)      carriage return, followed by linefeed
+         (*ANYCRLF)   any of the three above
+         (*ANY)       all Unicode newline sequences
+
+       These override the default and the options given to pcre_compile(). For
+       example, on a Unix system where LF is the default newline sequence, the
+       pattern
+
+         (*CR)a.b
+
+       changes the convention to CR. That pattern matches "a\nb" because LF is
+       no longer a newline. Note that these special settings,  which  are  not
+       Perl-compatible,  are  recognized  only at the very start of a pattern,
+       and that they must be in upper case.  If  more  than  one  of  them  is
+       present, the last one is used.
+
+       The  newline  convention  does  not  affect what the \R escape sequence
+       matches. By default, this is any Unicode  newline  sequence,  for  Perl
+       compatibility.  However, this can be changed; see the description of \R
+       in the section entitled "Newline sequences" below. A change of \R  set-
+       ting can be combined with a change of newline convention.
+
+
+CHARACTERS AND METACHARACTERS
+
+       A  regular  expression  is  a pattern that is matched against a subject
+       string from left to right. Most characters stand for  themselves  in  a
+       pattern,  and  match  the corresponding characters in the subject. As a
        trivial example, the pattern
 
          The quick brown fox
 
        matches a portion of a subject string that is identical to itself. When
-       caseless matching is specified (the PCRE_CASELESS option), letters  are
-       matched  independently  of case. In UTF-8 mode, PCRE always understands
-       the concept of case for characters whose values are less than  128,  so
-       caseless  matching  is always possible. For characters with higher val-
-       ues, the concept of case is supported if PCRE is compiled with  Unicode
-       property  support,  but  not  otherwise.   If  you want to use caseless

+DUPLICATE SUBPATTERN NUMBERS
+
+       Perl 5.10 introduced a feature whereby each alternative in a subpattern
+       uses  the same numbers for its capturing parentheses. Such a subpattern
+       starts with (?| and is itself a non-capturing subpattern. For  example,
+       consider this pattern:
+
+         (?|(Sat)ur|(Sun))day
+
+       Because  the two alternatives are inside a (?| group, both sets of cap-
+       turing parentheses are numbered one. Thus, when  the  pattern  matches,
+       you  can  look  at captured substring number one, whichever alternative
+       matched. This construct is useful when you want to  capture  part,  but
+       not all, of one of a number of alternatives. Inside a (?| group, paren-
+       theses are numbered as usual, but the number is reset at the  start  of
+       each  branch. The numbers of any capturing buffers that follow the sub-
+       pattern start after the highest number used in any branch. The  follow-
+       ing  example  is taken from the Perl documentation.  The numbers under-
+       neath show in which buffer the captured content will be stored.

+
+       A backreference or a recursive call to  a  numbered  subpattern  always
+       refers to the first one in the pattern with the given number.
+
+       An  alternative approach to using this "branch reset" feature is to use
+       duplicate named subpatterns, as described in the next section.

 NAMED SUBPATTERNS
 
        Identifying capturing parentheses by number is simple, but  it  can  be
        very  hard  to keep track of the numbers in complicated regular expres-
        sions. Furthermore, if an  expression  is  modified,  the  numbers  may
        change.  To help with this difficulty, PCRE supports the naming of sub-
-       patterns, something that Perl  does  not  provide.  The  Python  syntax
-       (?P<name>...)  is  used. References to capturing parentheses from other
-       parts of the pattern, such as  backreferences,  recursion,  and  condi-
-       tions, can be made by name as well as by number.
+       patterns. This feature was not added to Perl until release 5.10. Python
+       had  the  feature earlier, and PCRE introduced it at release 4.0, using
+       the Python syntax. PCRE now supports both the Perl and the Python  syn-
+       tax.
+
+       In  PCRE,  a subpattern can be named in one of three ways: (?<name>...)
+       or (?'name'...) as in Perl, or (?P<name>...) as in  Python.  References
+       to capturing parentheses from other parts of the pattern, such as back-
+       references, recursion, and conditions, can be made by name as  well  as
+       by number.
 
        Names  consist  of  up  to  32 alphanumeric characters and underscores.
        Named capturing parentheses are still  allocated  numbers  as  well  as
-       names. The PCRE API provides function calls for extracting the name-to-
-       number translation table from a compiled pattern. There is also a  con-

+       By default, a name must be unique within a pattern, but it is  possible
        to relax this constraint by setting the PCRE_DUPNAMES option at compile
-       time.  This  can  be useful for patterns where only one instance of the
-       named parentheses can match. Suppose you want to match the  name  of  a
-       weekday,  either as a 3-letter abbreviation or as the full name, and in
+       time. This can be useful for patterns where only one  instance  of  the
+       named  parentheses  can  match. Suppose you want to match the name of a
+       weekday, either as a 3-letter abbreviation or as the full name, and  in
        both cases you want to extract the abbreviation. This pattern (ignoring
        the line breaks) does the job:
 
-         (?P<DN>Mon|Fri|Sun)(?:day)?|
-         (?P<DN>Tue)(?:sday)?|
-         (?P<DN>Wed)(?:nesday)?|

-         (?P<DN>Sat)(?:urday)?

-       match.  The convenience  function  for  extracting  the  data  by  name
-       returns  the  substring  for  the first, and in this example, the only,
-       subpattern of that name that matched.  This  saves  searching  to  find

-       unique named subpattern from elsewhere in the  pattern,  the  one  that
-       corresponds  to  the  lowest number is used. For further details of the

+       unsigned  number  or  a negative number, optionally enclosed in braces.

+       An unsigned number specifies an absolute reference without the  ambigu-

+
+       the  condition is true if the most recent recursion is into the subpat-

+

+       there may be only one alternative  in  the  subpattern.  It  is  always
+       skipped  if  control  reaches  this  point  in the pattern; the idea of
+       DEFINE is that it can be used to define "subroutines" that can be  ref-
+       erenced  from elsewhere. (The use of "subroutines" is described below.)
+       For example, a pattern to match an IPv4 address could be  written  like
+       this (ignore whitespace and line breaks):
+
+         (?(DEFINE) (?<byte> 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+         \b (?&byte) (\.(?&byte)){3} \b
+
+       The  first part of the pattern is a DEFINE group inside which a another
+       group named "byte" is defined. This matches an individual component  of
+       an  IPv4  address  (a number less than 256). When matching takes place,
+       this part of the pattern is skipped because DEFINE acts  like  a  false
+       condition.
+
+       The rest of the pattern uses references to the named group to match the
+       four dot-separated components of an IPv4 address, insisting on  a  word
+       boundary at each end.

+       tricky.  This is made easier by the use of relative references. (A Perl
+       5.10 feature.)  Instead of (?1) in the  pattern  above  you  can  write
+       (?-2) to refer to the second most recently opened parentheses preceding
+       the recursion. In other  words,  a  negative  number  counts  capturing
+       parentheses leftwards from the point at which it is encountered.
+
+       It  is  also  possible  to refer to subsequently opened parentheses, by
+       writing references such as (?+2). However, these  cannot  be  recursive
+       because  the  reference  is  not inside the parentheses that are refer-
+       enced. They are always "subroutine" calls, as  described  in  the  next
+       section.
+
+       An  alternative  approach is to use named parentheses instead. The Perl
+       syntax for this is (?&name); PCRE's earlier syntax  (?P>name)  is  also
+       supported. We could rewrite the above example as follows:
+
+         (?<pn> \( ( (?>[^()]+) | (?&pn) )* \) )
+
+       If  there  is more than one subpattern with the same name, the earliest
+       one is used.
+
+       This particular example pattern that we have been looking  at  contains
+       nested  unlimited repeats, and so the use of atomic grouping for match-
+       ing strings of non-parentheses is important when applying  the  pattern
+       to strings that do not match. For example, when this pattern is applied
+       to
 
          (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
 
-       it  yields "no match" quickly. However, if atomic grouping is not used,

        have to be tested before failure can be reported.
 
        At the end of a match, the values set for any capturing subpatterns are
        those from the outermost level of the recursion at which the subpattern
-       value is set.  If you want to obtain  intermediate  values,  a  callout

        tion.
 
        PCRE provides a similar feature, but of course it cannot obey arbitrary
        Perl code. The feature is called "callout". The caller of PCRE provides

-       external function is to be called. If you want  to  identify  different

+BACKTRACKING CONTROL
+
+       Perl 5.10 introduced a number of "Special Backtracking Control  Verbs",
+       which are described in the Perl documentation as "experimental and sub-
+       ject to change or removal in a future version of Perl". It goes  on  to
+       say:  "Their usage in production code should be noted to avoid problems
+       during upgrades." The same remarks apply to the PCRE features described
+       in this section.
+
+       Since  these  verbs  are  specifically related to backtracking, most of
+       them can be  used  only  when  the  pattern  is  to  be  matched  using
+       pcre_exec(), which uses a backtracking algorithm. With the exception of
+       (*FAIL), which behaves like a failing negative assertion, they cause an
+       error if encountered by pcre_dfa_exec().
+
+       The  new verbs make use of what was previously invalid syntax: an open-
+       ing parenthesis followed by an asterisk. In Perl, they are generally of
+       the form (*VERB:ARG) but PCRE does not support the use of arguments, so
+       its general form is just (*VERB). Any number of these verbs  may  occur
+       in a pattern. There are two kinds:
+
+   Verbs that act immediately
+
+       The following verbs act as soon as they are encountered:
+
+          (*ACCEPT)
+
+       This  verb causes the match to end successfully, skipping the remainder
+       of the pattern. When inside a recursion, only the innermost pattern  is
+       ended  immediately.  PCRE  differs  from  Perl  in  what happens if the
+       (*ACCEPT) is inside capturing parentheses. In Perl, the data so far  is
+       captured: in PCRE no data is captured. For example:
+
+         A(A|B(*ACCEPT)|C)D
+
+       This  matches  "AB", "AAD", or "ACD", but when it matches "AB", no data
+       is captured.
+
+         (*FAIL) or (*F)
+
+       This verb causes the match to fail, forcing backtracking to  occur.  It
+       is  equivalent to (?!) but easier to read. The Perl documentation notes
+       that it is probably useful only when combined  with  (?{})  or  (??{}).
+       Those  are,  of course, Perl features that are not present in PCRE. The
+       nearest equivalent is the callout feature, as for example in this  pat-
+       tern:
+
+         a+(?C)(*FAIL)
+
+       A  match  with the string "aaaa" always fails, but the callout is taken
+       before each backtrack happens (in this example, 10 times).
+
+   Verbs that act after backtracking
+
+       The following verbs do nothing when they are encountered. Matching con-
+       tinues  with what follows, but if there is no subsequent match, a fail-
+       ure is forced.  The verbs  differ  in  exactly  what  kind  of  failure
+       occurs.
+
+         (*COMMIT)
+
+       This  verb  causes  the whole match to fail outright if the rest of the
+       pattern does not match. Even if the pattern is unanchored,  no  further
+       attempts  to find a match by advancing the start point take place. Once
+       (*COMMIT) has been passed, pcre_exec() is committed to finding a  match
+       at the current starting point, or not at all. For example:
+
+         a+(*COMMIT)b
+
+       This  matches  "xxaab" but not "aacaab". It can be thought of as a kind
+       of dynamic anchor, or "I've started, so I must finish."
+
+         (*PRUNE)
+
+       This verb causes the match to fail at the current position if the  rest
+       of the pattern does not match. If the pattern is unanchored, the normal
+       "bumpalong" advance to the next starting character then happens.  Back-
+       tracking  can  occur as usual to the left of (*PRUNE), or when matching
+       to the right of (*PRUNE), but if there is no match to the right,  back-
+       tracking  cannot  cross (*PRUNE).  In simple cases, the use of (*PRUNE)
+       is just an alternative to an atomic group or possessive quantifier, but
+       there  are  some uses of (*PRUNE) that cannot be expressed in any other
+       way.
+
+         (*SKIP)
+
+       This verb is like (*PRUNE), except that if the pattern  is  unanchored,
+       the  "bumpalong" advance is not to the next character, but to the posi-
+       tion in the subject where (*SKIP) was  encountered.  (*SKIP)  signifies
+       that  whatever  text  was  matched leading up to it cannot be part of a
+       successful match. Consider:
+
+         a+(*SKIP)b
+
+       If the subject is "aaaac...",  after  the  first  match  attempt  fails
+       (starting  at  the  first  character in the string), the starting point
+       skips on to start the next attempt at "c". Note that a possessive quan-
+       tifer  does not have the same effect in this example; although it would
+       suppress backtracking  during  the  first  match  attempt,  the  second
+       attempt  would  start at the second character instead of skipping on to
+       "c".
+
+         (*THEN)
+
+       This verb causes a skip to the next alternation if the rest of the pat-
+       tern does not match. That is, it cancels pending backtracking, but only
+       within the current alternation. Its name  comes  from  the  observation
+       that it can be used for a pattern-based if-then-else block:
+
+         ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+
+       If  the COND1 pattern matches, FOO is tried (and possibly further items
+       after the end of the group if FOO succeeds);  on  failure  the  matcher
+       skips  to  the second alternative and tries COND2, without backtracking
+       into COND1. If (*THEN) is used outside  of  any  alternation,  it  acts
+       exactly like (*PRUNE).

+
+PCRE REGULAR EXPRESSION SYNTAX SUMMARY
+
+       The  full syntax and semantics of the regular expressions that are sup-
+       ported by PCRE are described in  the  pcrepattern  documentation.  This
+       document contains just a quick-reference summary of the syntax.
+
+
+QUOTING
+
+         \x         where x is non-alphanumeric is a literal x
+         \Q...\E    treat enclosed characters as literal
+
+
+CHARACTERS
+
+         \a         alarm, that is, the BEL character (hex 07)
+         \cx        "control-x", where x is any character
+         \e         escape (hex 1B)
+         \f         formfeed (hex 0C)
+         \n         newline (hex 0A)
+         \r         carriage return (hex 0D)
+         \t         tab (hex 09)
+         \ddd       character with octal code ddd, or backreference
+         \xhh       character with hex code hh
+         \x{hhh..}  character with hex code hhh..
+
+
+CHARACTER TYPES
+
+         .          any character except newline;
+                      in dotall mode, any character whatsoever
+         \C         one byte, even in UTF-8 mode (best avoided)
+         \d         a decimal digit
+         \D         a character that is not a decimal digit
+         \h         a horizontal whitespace character
+         \H         a character that is not a horizontal whitespace character
+         \p{xx}     a character with the xx property
+         \P{xx}     a character without the xx property
+         \R         a newline sequence
+         \s         a whitespace character
+         \S         a character that is not a whitespace character
+         \v         a vertical whitespace character
+         \V         a character that is not a vertical whitespace character
+         \w         a "word" character
+         \W         a "non-word" character
+         \X         an extended Unicode sequence
+
+       In PCRE, \d, \D, \s, \S, \w, and \W recognize only ASCII characters.

 PCRE PERFORMANCE
 
-       Certain  items  that may appear in regular expression patterns are more
-       efficient than others. It is more efficient to use  a  character  class
-       like  [aeiou]  than  a set of alternatives such as (a|e|i|o|u). In gen-
-       eral, the simplest construction that provides the required behaviour is
-       usually  the  most  efficient.  Jeffrey Friedl's book contains a lot of
-       useful general discussion  about  optimizing  regular  expressions  for
-       efficient  performance. This document contains a few observations about
-       PCRE.
+       Two  aspects  of performance are discussed below: memory usage and pro-
+       cessing time. The way you express your pattern as a regular  expression
+       can affect both of them.
+
+
+MEMORY USAGE
+
+       Patterns are compiled by PCRE into a reasonably efficient byte code, so
+       that most simple patterns do not use much memory. However, there is one
+       case where memory usage can be unexpectedly large. When a parenthesized
+       subpattern has a quantifier with a minimum greater than 1 and/or a lim-
+       ited  maximum,  the  whole subpattern is repeated in the compiled code.
+       For example, the pattern
+
+         (abc|def){2,4}
+
+       is compiled as if it were
+
+         (abc|def)(abc|def)((abc|def)(abc|def)?)?
+
+       (Technical aside: It is done this way so that backtrack  points  within
+       each of the repetitions can be independently maintained.)
+
+       For  regular expressions whose quantifiers use only small numbers, this
+       is not usually a problem. However, if the numbers are large,  and  par-
+       ticularly  if  such repetitions are nested, the memory usage can become
+       an embarrassment. For example, the very simple pattern
+
+         ((ab){1,1000}c){1,3}
+
+       uses 51K bytes when compiled. When PCRE is compiled  with  its  default
+       internal  pointer  size of two bytes, the size limit on a compiled pat-
+       tern is 64K, and this is reached with the above pattern  if  the  outer
+       repetition is increased from 3 to 4. PCRE can be compiled to use larger
+       internal pointers and thus handle larger compiled patterns, but  it  is
+       better to try to rewrite your pattern to use less memory if you can.
+
+       One  way  of reducing the memory usage for such patterns is to make use
+       of PCRE's "subroutine" facility. Re-writing the above pattern as
+
+         ((ab)(?2){0,999}c)(?1){0,2}
+
+       reduces the memory requirements to 18K, and indeed it remains under 20K
+       even  with the outer repetition increased to 100. However, this pattern
+       is not exactly equivalent, because the "subroutine" calls  are  treated
+       as  atomic groups into which there can be no backtracking if there is a
+       subsequent matching failure. Therefore, PCRE cannot  do  this  kind  of
+       rewriting  automatically.   Furthermore,  there is a noticeable loss of
+       speed when executing the modified pattern. Nevertheless, if the  atomic
+       grouping  is  not  a  problem and the loss of speed is acceptable, this
+       kind of rewriting will allow you to process patterns that  PCRE  cannot
+       otherwise handle.
+
+
+PROCESSING TIME
+
+       Certain  items  in regular expression patterns are processed more effi-
+       ciently than others. It is more efficient to use a character class like
+       [aeiou]   than   a   set   of  single-character  alternatives  such  as
+       (a|e|i|o|u). In general, the simplest construction  that  provides  the
+       required behaviour is usually the most efficient. Jeffrey Friedl's book
+       contains a lot of useful general discussion  about  optimizing  regular
+       expressions  for  efficient  performance.  This document contains a few

+   Compiling PCRE to use heap instead of stack
+
        In environments where stack memory is constrained, you  might  want  to
        compile  PCRE to use heap memory instead of stack for remembering back-
        up points. This makes it run a lot more slowly, however. Details of how
-       to do this are given in the pcrebuild documentation.
+       to do this are given in the pcrebuild documentation. When built in this
+       way, instead of using the stack, PCRE obtains and frees memory by call-
+       ing  the  functions  that  are  pointed to by the pcre_stack_malloc and
+       pcre_stack_free variables. By default,  these  point  to  malloc()  and
+       free(),  but you can replace the pointers to cause PCRE to use your own
+       functions. Since the block sizes are always the same,  and  are  always
+       freed in reverse order, it may be possible to implement customized mem-
+       ory handlers that are more efficient than the standard functions.
 
-       In Unix-like environments, there is not often a problem with the stack,
-       though the default limit on stack size varies from  system  to  system.
-       Values  from 8Mb to 64Mb are common. You can find your default limit by
-       running the command:
-
-         ulimit -s
-
-       The effect of running out of stack is often SIGSEGV,  though  sometimes
-       an error message is given. You can normally increase the limit on stack
-       size by code such as this:
-
-         struct rlimit rlim;
-         getrlimit(RLIMIT_STACK, &rlim);
-         rlim.rlim_cur = 100*1024*1024;
-         setrlimit(RLIMIT_STACK, &rlim);
-
-       This reads the current limits (soft and hard) using  getrlimit(),  then
-       attempts  to  increase  the  soft limit to 100Mb using setrlimit(). You
-       must do this before calling pcre_exec().

        -d action, --directories=action
                  If an input path is a directory, "action" specifies how it is
-                 to  be  processed.   Valid  values  are "read" (the default),

-       -e pattern, --regex=pattern,

-                 can  be  used multiple times in order to specify several pat-
-                 terns. It can also be used as a way of  specifying  a  single
-                 pattern  that starts with a hyphen. When -e is used, no argu-
-                 ment pattern is taken from the command  line;  all  arguments
-                 are treated as file names. There is an overall maximum of 100
-                 patterns. They are applied to each line in the order in which
-                 they  are  defined until one matches (or fails to match if -v
-                 is used). If -f is used with -e, the  command  line  patterns
-                 are  matched  first,  followed by the patterns from the file,
-                 independent of the order in which these  options  are  speci-
-                 fied.  Note that multiple use of -e is not the same as a sin-
-                 gle pattern with alternatives. For  example,  X|Y  finds  the
-                 first  character in a line that is X or Y, whereas if the two
-                 patterns are given separately, pcregrep  finds  X  if  it  is
-                 present, even if it follows Y in the line. It finds Y only if
-                 there is no X in the line. This really matters  only  if  you
-                 are using -o to show the portion of the line that matched.
+       -e pattern, --regex=pattern, --regexp=pattern
+                 Specify a pattern to be matched. This option can be used mul-
+                 tiple times in order to specify several patterns. It can also
+                 be  used  as a way of specifying a single pattern that starts
+                 with a hyphen. When -e is used, no argument pattern is  taken
+                 from  the  command  line;  all  arguments are treated as file
+                 names. There is an overall maximum of 100 patterns. They  are
+                 applied  to  each line in the order in which they are defined
+                 until one matches (or fails to match if -v is used). If -f is
+                 used  with  -e,  the command line patterns are matched first,
+                 followed by the patterns from the file,  independent  of  the
+                 order  in which these options are specified. Note that multi-
+                 ple use of -e is not the same as a single pattern with alter-
+                 natives. For example, X|Y finds the first character in a line
+                 that is X or Y, whereas if the two patterns are  given  sepa-
+                 rately, pcregrep finds X if it is present, even if it follows
+                 Y in the line. It finds Y only if there is no X in the  line.
+                 This  really  matters  only  if  you are using -o to show the
+                 part(s) of the line that matched.
 
        --exclude=pattern
                  When pcregrep is searching the files in a directory as a con-
-                 sequence of the -r (recursive search) option, any files whose
-                 names  match  the pattern are excluded. The pattern is a PCRE
-                 regular expression. If a file name matches both --include and
-                 --exclude,  it  is  excluded. There is no short form for this
+                 sequence  of  the  -r  (recursive search) option, any regular
+                 files whose names match the pattern are excluded. Subdirecto-
+                 ries  are  not  excluded  by  this  option; they are searched
+                 recursively, subject to the --exclude_dir  and  --include_dir
+                 options.  The  pattern  is  a PCRE regular expression, and is
+                 matched against the final component of the file name (not the
+                 entire  path).  If  a  file  name  matches both --include and
+                 --exclude, it is excluded.  There is no short form  for  this
                  option.
 
+       --exclude_dir=pattern
+                 When  pcregrep  is searching the contents of a directory as a
+                 consequence of the -r (recursive search) option,  any  subdi-
+                 rectories  whose  names match the pattern are excluded. (Note
+                 that the --exclude option does  not  affect  subdirectories.)
+                 The  pattern  is  a  PCRE  regular expression, and is matched
+                 against the final component  of  the  name  (not  the  entire
+                 path).  If a subdirectory name matches both --include_dir and
+                 --exclude_dir, it is excluded. There is  no  short  form  for
+                 this option.

                  used with -F. They apply to each of the fixed strings. A line
                  is selected if any of the fixed strings are found in it (sub-
                  ject to -w or -x, if present).
 
        -f filename, --file=filename
-                 Read  a  number  of patterns from the file, one per line, and

+                 Read a number of patterns from the file, one  per  line,  and
+                 match  them against each line of input. A data line is output
                  if any of the patterns match it. The filename can be given as
                  "-" to refer to the standard input. When -f is used, patterns
-                 specified  on  the command line using -e may also be present;
+                 specified on the command line using -e may also  be  present;
                  they are tested before the file's patterns. However, no other
-                 pattern  is  taken  from  the command line; all arguments are

        -N newline-type, --newline=newline-type
-                 The PCRE library supports three different character sequences
-                 for indicating the ends of lines. They are the single-charac-
-                 ter sequences CR (carriage return) and LF (linefeed), and the
-                 two-character sequence CR, LF. When the library is  built,  a
-                 default  line-ending  sequence is specified. This is normally
-                 the standard sequence for the operating system. Unless other-
-                 wise specified by this option, pcregrep uses the default. The
-                 possible values for this option are CR,  LF,  or  CRLF.  This
-                 makes  it  possible  to  use pcregrep on files that have come
-                 from other environments without having to modify  their  line
-                 endings.   If  the  data that is being scanned does not agree
-                 with the convention set by this option, pcregrep  may  behave

 The original operation of PCRE was on strings of one-byte characters. However,
 there is now also support for UTF-8 character strings. To use this, you must
 build PCRE to include UTF-8 support, and then call \fBpcre_compile()\fP with

+PCRE supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The

+about newlines, and shows how to set the newline convention in the
+\fIoptions\fP arguments for the compiling and matching functions.
 .P
+It is also possible to specify a newline convention by starting a pattern
+string with one of the following five sequences:
+.sp
+  (*CR)        carriage return
+  (*LF)        linefeed
+  (*CRLF)      carriage return, followed by linefeed
+  (*ANYCRLF)   any of the three above
+  (*ANY)       all Unicode newline sequences
+.sp
+These override the default and the options given to \fBpcre_compile()\fP. For
+example, on a Unix system where LF is the default newline sequence, the pattern
+.sp
+  (*CR)a.b
+.sp
+changes the convention to CR. That pattern matches "a\enb" because LF is no
+longer a newline. Note that these special settings, which are not
+Perl-compatible, are recognized only at the very start of a pattern, and that
+they must be in upper case. If more than one of them is present, the last one
+is used.

+The newline convention does not affect what the \eR escape sequence matches. By

+Perl 5.10 introduced a feature whereby each alternative in a subpattern uses
+the same numbers for its capturing parentheses. Such a subpattern starts with
+(?| and is itself a non-capturing subpattern. For example, consider this
+pattern:
+.sp
+  (?|(Sat)ur|(Sun))day
+.sp
+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+buffers that follow the subpattern start after the highest number used in any
+branch. The following example is taken from the Perl documentation.

+The new verbs make use of what was previously invalid syntax: an opening
+parenthesis followed by an asterisk. In Perl, they are generally of the form
+(*VERB:ARG) but PCRE does not support the use of arguments, so its general
+form is just (*VERB). Any number of these verbs may occur in a pattern. There
+are two kinds:
+.
+.SS "Verbs that act immediately"
+.rs
+.sp
+The following verbs act as soon as they are encountered:
+.sp
+   (*ACCEPT)
+.sp
+This verb causes the match to end successfully, skipping the remainder of the
+pattern. When inside a recursion, only the innermost pattern is ended
+immediately. PCRE differs from Perl in what happens if the (*ACCEPT) is inside
+capturing parentheses. In Perl, the data so far is captured: in PCRE no data is
+captured. For example:
+.sp
+  A(A|B(*ACCEPT)|C)D
+.sp
+This matches "AB", "AAD", or "ACD", but when it matches "AB", no data is
+captured.
+.sp
+  (*FAIL) or (*F)
+.sp
+This verb causes the match to fail, forcing backtracking to occur. It is
+equivalent to (?!) but easier to read. The Perl documentation notes that it is
+probably useful only when combined with (?{}) or (??{}). Those are, of course,
+Perl features that are not present in PCRE. The nearest equivalent is the
+callout feature, as for example in this pattern:
+.sp
+  a+(?C)(*FAIL)
+.sp
+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+.
+.SS "Verbs that act after backtracking"
+.rs
+.sp
+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is no subsequent match, a failure is forced.
+The verbs differ in exactly what kind of failure occurs.
+.sp
+  (*COMMIT)
+.sp
+This verb causes the whole match to fail outright if the rest of the pattern
+does not match. Even if the pattern is unanchored, no further attempts to find
+a match by advancing the start point take place. Once (*COMMIT) has been
+passed, \fBpcre_exec()\fP is committed to finding a match at the current
+starting point, or not at all. For example:
+.sp
+  a+(*COMMIT)b
+.sp
+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish."
+.sp
+  (*PRUNE)
+.sp
+This verb causes the match to fail at the current position if the rest of the
+pattern does not match. If the pattern is unanchored, the normal "bumpalong"
+advance to the next starting character then happens. Backtracking can occur as
+usual to the left of (*PRUNE), or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE).
+In simple cases, the use of (*PRUNE) is just an alternative to an atomic
+group or possessive quantifier, but there are some uses of (*PRUNE) that cannot
+be expressed in any other way.
+.sp
+  (*SKIP)
+.sp
+This verb is like (*PRUNE), except that if the pattern is unanchored, the
+"bumpalong" advance is not to the next character, but to the position in the
+subject where (*SKIP) was encountered. (*SKIP) signifies that whatever text
+was matched leading up to it cannot be part of a successful match. Consider:
+.sp
+  a+(*SKIP)b
+.sp
+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifer does not have the same
+effect in this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+.sp
+  (*THEN)
+.sp
+This verb causes a skip to the next alternation if the rest of the pattern does
+not match. That is, it cancels pending backtracking, but only within the
+current alternation. Its name comes from the observation that it can be used
+for a pattern-based if-then-else block:
+.sp
+  ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+.sp
+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If (*THEN)
+is used outside of any alternation, it acts exactly like (*PRUNE).

 .SH "PCRE PERFORMANCE"
 .rs
 .sp
-Certain items that may appear in regular expression patterns are more efficient
+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+.
+.SH "MEMORY USAGE"
+.rs
+.sp
+Patterns are compiled by PCRE into a reasonably efficient byte code, so that
+most simple patterns do not use much memory. However, there is one case where
+memory usage can be unexpectedly large. When a parenthesized subpattern has a
+quantifier with a minimum greater than 1 and/or a limited maximum, the whole
+subpattern is repeated in the compiled code. For example, the pattern
+.sp
+  (abc|def){2,4}
+.sp
+is compiled as if it were
+.sp
+  (abc|def)(abc|def)((abc|def)(abc|def)?)?
+.sp
+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+.P
+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+.sp
+  ((ab){1,1000}c){1,3}
+.sp
+uses 51K bytes when compiled. When PCRE is compiled with its default internal
+pointer size of two bytes, the size limit on a compiled pattern is 64K, and
+this is reached with the above pattern if the outer repetition is increased
+from 3 to 4. PCRE can be compiled to use larger internal pointers and thus
+handle larger compiled patterns, but it is better to try to rewrite your
+pattern to use less memory if you can.
+.P
+One way of reducing the memory usage for such patterns is to make use of PCRE's
+.\" HTML <a href="pcrepattern.html#subpatternsassubroutines">
+.\" </a>
+"subroutine"
+.\"
+facility. Re-writing the above pattern as
+.sp
+  ((ab)(?2){0,999}c)(?1){0,2}
+.sp
+reduces the memory requirements to 18K, and indeed it remains under 20K even
+with the outer repetition increased to 100. However, this pattern is not
+exactly equivalent, because the "subroutine" calls are treated as
+.\" HTML <a href="pcrepattern.html#atomicgroup">
+.\" </a>
+atomic groups
+.\"
+into which there can be no backtracking if there is a subsequent matching
+failure. Therefore, PCRE cannot do this kind of rewriting automatically.
+Furthermore, there is a noticeable loss of speed when executing the modified
+pattern. Nevertheless, if the atomic grouping is not a problem and the loss of
+speed is acceptable, this kind of rewriting will allow you to process patterns
+that PCRE cannot otherwise handle.
+.
+.SH "PROCESSING TIME"

+Certain items in regular expression patterns are processed more efficiently

+/* This file contains character tables that are used when no external tables
+are passed to PCRE by the application that calls it. The tables are used only
+for characters whose code values are less than 256.
+
+This is a default version of the tables that assumes ASCII encoding. A program
+called dftables (which is distributed with PCRE) can be used to build
+alternative versions of this file. This is necessary if you are running in an
+EBCDIC environment, or if you want to default to a different encoding, for
+example ISO-8859-1. When dftables is run, it creates these tables in the
+current locale. If PCRE is configured with --enable-rebuild-chartables, this
+happens automatically.
+
+The following #includes are present because without the gcc 4.x may remove the
+array definition from the final binary if PCRE is built into a static library
+and dead code stripping is activated. This leads to link errors. Pulling in the
+header ensures that the array gets flagged as "someone outside this compilation
+unit might reference this" and so it will always be supplied to the linker. */

+encountered in a character class. It checks whether this is followed by a
+sequence of characters terminated by a matching ":]" or ".]" or "=]". If we
+reach an unescaped ']' without the special preceding character, return FALSE.
+
+Originally, this function only recognized a sequence of letters between the
+terminators, but it seems that Perl recognizes any sequence of characters,
+though of course unknown POSIX names are subsequently rejected. Perl gives an
+"Unknown POSIX class" error for [:f\oo:] for example, where previously PCRE
+didn't consider this to be a POSIX class. Likewise for [:1234:].
+
+The problem in trying to be exactly like Perl is in the handling of escapes. We
+have to be sure that [abc[:x\]pqr] is *not* treated as containing a POSIX
+class, but [abc[:x\]pqr:]] is (so that an error can be generated). The code
+below handles the special case of \], but does not try to do any other escape
+processing. This makes it different from Perl for cases such as [:l\ower:]
+where Perl recognizes it as the POSIX class "lower" but PCRE does not recognize
+"l\ower". This is a lesser evil that not diagnosing bad classes when Perl does,
+I think.

 obtained from malloc() instead instead of on the stack. Macros are used to
 achieve this so that the actual code doesn't look very different to what it
 always used to.
+
+The original heap-recursive code used longjmp(). However, it seems that this
+can be very slow on some operating systems. Following a suggestion from Stan
+Switzer, the use of longjmp() has been abolished, at the cost of having to
+provide a unique number for each call to RMATCH. There is no way of generating
+a sequence of numbers at compile time in C. I have given them names, to make
+them stand out more clearly.
+
+Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
+FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
+tests. Furthermore, not using longjmp() means that local dynamic variables
+don't have indeterminate values; this has meant that the frame size can be
+reduced because the result can be "passed back" by straight setting of the
+variable instead of being passed in the frame.

+/* When compiling a DLL for Windows, the exported symbols have to be declared
+using some MS magic. I found some useful information on this web page:
+http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
+information there, using __declspec(dllexport) without "extern" we have a
+definition; with "extern" we have a declaration. The settings here override the
+setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
+which is all that is needed for applications (they just import the symbols). We
+use:
+
+  PCRE_EXP_DECL       for declarations
+  PCRE_EXP_DEFN       for definitions of exported functions
+  PCRE_EXP_DATA_DEFN  for definitions of exported variables
+
+The reason for the two DEFN macros is that in non-Windows environments, one
+does not want to have "extern" before variable definitions because it leads to
+compiler warnings. So we distinguish between functions and variables. In
+Windows, the two should always be the same.
+
+The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
+which is an application, but needs to import this file in order to "peek" at
+internals, can #include pcre.h first to get an application's-eye view.
+
+In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
+special-purpose environments) might want to stick other stuff in front of
+exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
+PCRE_EXP_DATA_DEFN only if they are not already set. */
