[Freeswitch-users] configure fails to find libpq

[Steven Ayre]

To answer your question of what the test is doing, it'll take the required
flags/libs from pg_config (which it looks like it found) and then try
compiling a tiny program linking to it to check if the library exists and
when testing functions if that function is exported by that version of the
library. Any compile error means 'no'. That ac_ variable is checking if its
'set' which'd mean the test passed. Config.log will show all the tests
being run and any error output for them.
