system, apache, or php's regex library by using the --with-regex option.
"php" is the default; if you use --with-apache in combination with
Apache 1.3.x, the default is "apache".
and php_regex.h figures out which regex header files to include and
defines symbols that prevents other stuff from including the wrong versions
of regex header files.
* There are now -I directives for the absolute path of php4, php4/libzend and the builddir for
the Apache module, so we can #include any php/Zend header.
* Rename config.h to php_config.h
