As described in the manual section Version Numbers [0], we should use the
git-version procedure to create the package's version. As the most
recent Git tag before the specified commit is 1.4, it would be like
this:

(version (git-version "1.4" revision commit))

The license header of 'src/rdate.c' says "version 2 of the License, or
(at your option) any later version.", so the license is gpl2+.

Can you send a revised patch?
