Looks fine.

Another option (just to avoid this particular #if/#endif) would
be to add "regexp" to the list of modules pulled in from gnulib.
Probably not worth it right now, though, since the code that would
use it has to remain #ifdef'd out.

Instead of adding the #if/else blocks above,
how about adding these in some header file?

#ifndef HAVE_GETGID
static inline gid_t getgid (void) { return 0; }
#endif

#ifndef HAVE_GETUID
static inline uid_t getuid (void) { return 0; }
#endif
