Sure.

I tried this solution before the one I posted.  I don't like it much
because it always causes extra work: when the stamp file is not the
one with the oldest time stamp, every 'make' invokes at least some
testing rule.  So you either have to either adjust stamps in the rule,
or have this as requirement for moopp, which looks messy to me.
(And for simplicity you should always remove the stamp file first, to
minimize chances of a parallel rebuild invoking two rules at the same
time.)

Probably ok, I guess.

Thanks for mentioning: yes, I do.  I'll propose a fix to Automake.
