   The way we do this in glibc-land is to set VERSION=2.10.90.  This then
   becomes the first prerelease version number.  binutils doesn't have
   prereleases (well, we haven't yet) but the important thing is that
   someone looking at 2.10.90 should be aware that there's something
   funny about the release.

According to the ``GNU Maintenance Instructions'' (maintain.info),
this is the "official" GNU way to give version numbers.
