  I have a patch prepared on my disk.
The problem was that if started with
        m4_define([gnumeric_version_epoch], [1])
then the m4_define disappeared after an autoupdate run.

The fix happen to be quite a big change, but I'm quite sure it makes
things more consistent.  Please see the attached patch.

IIRC, I tested the patch back then, so the only step remaining is to
write an autotest check for this.  I even have an impression that it
existed on my disk at certain moment, but it not there now. :-(

Then we shall test whether the bugs below survive this patch.

Good night for now,
        Stepan Kasal
