Hello,
I could find on this ML archives only a thread about this subject: to
consider the file checksum instead of the timestamp.
Other systems like scons already support this feature and it would be
great to have it for GNU Make too.
I attached a patch against the current CVS to add --use-checks

I sent a message to this mailing list some months ago but I still didn't
get an answer. Doesn't GNU Make want to consider files checksum in
addition to mtime?

Hi Philip,
it looks like a good idea. Do you think it worths to be discussed with
automake hackers?
Cheers,
Giuseppe
