No, but you can read the thread containing this message:

http://lists.gnu.org/archive/html/bug-gnulib/2004-10/msg00171.html

to see some of the issues here, and why gnulib getopt.m4 rejects BSD's
emulation of GNU getopt.

There we have quite a few more tests; see
<http://cvs.savannah.gnu.org/viewcvs/*checkout*/gnulib/m4/regex.m4?root=gnulib>.
Even glibc doesn't satisfy the current tests, so there's no shame in
your failing them too.  I'm working on getting glibc fixed, but these
things take time.  (To some extent its an arms-race problem as we can
add tests faster than the libc maintainers can fix the regex
bugs.... :-)

You can try them out by downloading, say
<ftp://alpha.gnu.org/gnu/coreutils/coreutils-6.2.tar.bz2>, configuring
with LIBS=-lgnuregex or whatever magic you like, and then seeing
whether 'configure' decides to use your regex implementation.

If it works, I suppose we can try to automate adding the linker magic
and put that into regex.m4.  But I can't resist asking: why can't the
BSD folks just make a gnulib-compatible regex be the default?  That
would make life easier for lots of people.
