necessary, because we can change the value of INCLUDES globally in one
place (configure.in).
Also add two defines in thread-safe mode
(_REENTRANT and POSIX_PTHREAD_SEMANTICS)
with libtool components
* SAPI targets can enable thread-safe mode and define
shared/static/program build target
* all configure scripts use the same config.cache
* phplibdir is $(top_builddir)/modules to avoid
permission problems
* sapi/*/Makefile.inc are gone
* runpath handling cleaned up
* top-level Makefile.in obsoleted through Makefile.am
* --enable-versioning uses libtool's cleaner and more
portable -export-symbols feature
PCRE library can be found at ftp://ftp.cus.cam.ac.uk/pub/software/programs/pcre/
config.m4 will be updated to be more robust later on.
perl_match() takes a regular expression, the source string, and the array
for subpattern matches.
perl_replace() takes a regular expression, the search string, and the replacement
string.
Regular expression is specified using delimiters and options. Example:
perl_match("/<[a-z]*>/i", $text, $tags);
More stuff is coming soon.
