But m4_version_prereq can not know whether version 2.69.345 is before or
after the prerelease 2.69e.

I think the real fix is therefore to change the Autoconf build system
so that instead of 2.69.301-14265 it would produce 2.69b.67-14265.
Then m4_version_prereq would know that this was between 2.69b and 2.69c.

Most probably either 'git-version-gen' or some use of 'git describe'
can achieve this.
