It sounds like there is no perfect solution here, but I think it'd be
better to be consistent with GNU make.
The GNU Make convention is that FC and FFLAGS are a pair, and F77 and
F77FLAGS are a pair. By default they have the same meaning, since the
default value of F77 is "$(FC)", and the default value of F77FLAGS is
"$(FFLAGS)". The default value of FFLAGS is empty; the default value
of FC is "fortran" on VMS, "cf77" on Cray, "xlf" on _IBMR2, "fc" on
Convex, and "f77" otherwise.
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.
