You can use PCRE instead, but make sure to wrap it in #ifdef 
HAVE_LIBPCRE (which requires having #ifdef HAVE_CONFIG_H /
#include "config.h" at the top).  However, the configure script will 
prefer GRegex over PCRE (see configure.in).  I didn't look carefully at 
how GRegex was added to Wireshark as someone else committed it, but it 
sounds like GRegex is preferred and pcre *may* go away some day 
(probably not anytime soon though).
