[bcc'ing everyone who reported problems with m4 1.4.12 or the previous
snapshot; thanks again for your previous feedback]

I obviously missed releasing GNU M4 1.4.13 by the end of 2008, but maybe
I'll make January.  Gnulib has had some improvements to fix bugs reported
on the last snapshot, but also introduced some new unit tests that align
with the new POSIX 2008 release.  To ensure as much portability as
possible in the next M4 release, I'd like some feedback on whether the
current snapshot works for you.  The snapshot is available at:
