Well, I don't know where you got this magic number 301-14265 from.

In my tests with version 2.69c,
  m4_version_prereq([2.70], NEW, OLD)
picked the OLD code, whereas
  m4_version_prereq([2.69c], NEW, OLD)
picked the NEW code.

The version comparison code (see m4sugar.m4, macro m4_version_unletter) seems
to handle prerelease version numbers fine.

In a git checkout of the Autoconf repository, when I run
  build-aux/git-version-gen .tarball-version
it prints

As far as I can see, versions of the form 2.69.xx-yyy will all be considered
smaller than even the first prerelease (2.69a); so that's probably not a
desirable way to designate intermediate versions between 2.69b and 2.69d.
