I agree that consistency with GNU Make is a good thing, but I shudder at
the thought of the howls of protest that might arise from all the existing
Fortran users.
Moreover, I suspect that consistency with automake (which uses $F77 and
$FFLAGS) should take priority over consistency with the implicit rules in
GNU Make.

I agree.
