Neither mod_java nor any other module that uses C++ (eg. mod_python)
will currently link on MacOS, because on them maccies you apparently
have to link C++ code with g++ instead of ld like on every other
operating system in the world.

You can probably link it manually by using g++ instead of gcc in that
last command, and dropping the -std=c99.
