I'm in South America for 3 weeks from Saturday, so will be unlikely to 
look at this myself until September.

However, PCRE has a posix-compatible API, so it could be as simple as 
replacing:

#include <regex.h>

...with:

#ifdef HAVE_PCREPOSIX_H
  #include <pcreposix.h>
#else
  #include <regex.h>
#endif

...and adding "-lpcreposix" to the link libs. I might have a quick go at 
that today.
