PHP will not #include <regex.h> in FC3 and later. If you file a bug against FC2 php I can probably fix it there for future updates.
(the fact that both httpd and PHP think it's a good idea to reimplement the POSIX regex interface in random different ways is an accident waiting to happen; I've fixed it in the httpd 2.1 branch but PHP is another matter)

Thanks. Yeah, it looks like anyone wanting to manage Apache from PHP has to keep the code carefully separated in separate modules right now to avoid the header collision.
