Historically lib/regexp.[ch] tracked what was in the GNU C library,
which had diverged from Emacs but nobody had time or inclination to
merge them.  Now, however, the GNU C library has a new implementation
of regexp.[ch] -- it supports the POSIX i18n features that the older
one did not -- so the "track glibc" motivation is now absent.

I don't see why we need to have 3 versions of regexp.c -- 2 is enough
-- but perhaps Jim Meyering nows more about this and can say whether
we there is any reason to distinguish the Emacs version from the
gnulib version.

Ideally we could merge all 3 versions, but that'd be more work.
