There have been various attempts at allowing to extend Automake more
freely.  I can't remember any proposed patch that didn't need a lot
of work (documentation, regression tests, and/or just portability
fixes), and I also can't remember if any dealt with generic dependency
tracking support.  But that doesn't mean they don't exist, just that
neither you nor me have searched the mail archives yet.  ;-)

Since you seem to already have a suitable non-Automake mechanism in
place, would you be willing to point us to it?  Does it clash with
Automake in any way (note that you can override many rules and variables
that Automake otherwise controls)?

Cheers,
Ralf
