Using the Autoconf version number makes better sense for upstream
Autoconf.  I chose a time stamp because I wanted a different
version number every time I created a Debian package.  It was
slightly easier to use a time stamp than to extract the Debian
package version.

These changes would be fine, of course.  I don't know whether
this is considered legally significant, or whether my actual code
to do this is of any interest, as opposed to the idea.  If you
want me to sign papers for Autoconf I'll do so.
RMS on DRM: "This ought to be a crime. And, if we had governments of the
people, by the people, for the people, then the executives of those companies
would be in prison.  But they're not in prison, and the reason is that we have
government of the people, by the sell-outs, for the corporations."
