This patch properly fixes support for CGI in PHP. For backwards compatible
broken behaviour, cgi.fix_pathinfo can be set to zero in php.ini.
CGI failed to work under apache at all, either using the cgi-script directive
or as a ScriptAlias setup. Typicaly it would try to parse itself. This will
still happen if you dissable fix_pathinfo, and set DISCARD_PATH.
This also fixes PATH_INFO, and finally we can run pres2 under cgi or fastcgi.
This patch has been tested under Apache 1.3, 2.0, IIS, as both cgi and fastcgi,
on Windows and OSX. A followup patch with build stuff for linux will follow.
include fastcgi library for ease of windows builds
NOTE: included fastcgi library is modified for thread safety, but
fastcgi support in cgi_main.c is only written for single
threaded serving. This does not present any issue for using
fastcgi.
