replacing FreeBSD's -lgnuregex with GNUlib's version

A recent discussion on the gm4 and gnulib mailing lists over the merits of 
gm4's bundling of its own regex implementation has produced the suggestion, 
that we replace our src/gnu/lib/libregex (which is currently obtained from 
fedora-glibc-2_3_4-21) with gnulib's implementation.

The latter is claimed to be more actively maintained and with more bug fixes, 
than glibc people have managed to incorporate.

Does anyone have a strong preference for fedora/glibc implementation currently 
in use, or should we follow this advice (source -- regex' maintainer for 
gnulib -- CC-ed) and switch over?

You can just do a diff between glibc and regex to find the list of
patches.  They aren't marshaled into a coherent set of small patches,
which is the bottleneck.  However, you _can_ just use the gnulib
version, which is a popular option.
