Recent Autoconf has m4_version_compare for a comparison at autoconf run
time, and AS_VERSION_COMPARE for one at configure run time.  gnulib has
a module strverscmp for C comparison code.

IIRC there were slight, probably unintended differences in the
comparison algorithms; or at least, some bugs have been fixed in the not
too distant past.
