Is it possible to transform a regex pattern that uses this feature into a
POSIX Extended Regex, that doesn't use it? If yes, you could parse the
regex - this is not the most difficult thing to do, and you can also take
the code from grep's dfa.c - and pass the transformed pattern to the system's
regex facility.
