POSIX regex isn't available on all platforms, on some it is slower than PCRE, and on others (like Solaris 2.5 and earlier) it is just broken. We chose to use it by default in 2.0 because there weren't any platforms for which PCRE was slower than the system regex and we were tired of dealing with misdirected bug reports. ....Roy
