First, understand that the gnulib regexp used glibc as its upstream
source. This URL to gnulib CVS:
contains a cross-reference of all the glibc bugzilla entries (search for
$LIBCSRC/posix/reg*, and the open bugs are listed as links above the
affected files) that were created to track differences between glibc and
gnulib. While some of the bugzilla entries have since been closed, there
are still some known differences, and by reading the bugzilla entries, you
will find instances where gnulib has a patch for POSIX compliance that
glibc has not picked up. Since m4 2.0 will use the gnulib regexp module
by default, you will be missing out on all these patches to deficiencies
in glibc if you insist on using the glibc regexp.

Then you can offer to help by speeding up the release of libtool 2.0, so
that the release of m4 2.0 can follow.
Life is short - so eat dessert first!
