All, I'm cleaning up configure.ac a bit and I came across this: FC=$F77 AC_SUBST(FC) which makes FC an alias for F77 in Makefiles. However, all of the Makefile rules I see use $F77. Is there something I'm missing or can we delete this as cruft?
Not sure. My only guess would be maybe autoconf wants FC to be defined. According to this:
http://www.hep.by/gnu/autoconf/Fortran-Compiler.htmlFC can be Fortran 77, 90 or 95. But also the way to make the definition seems slightly different than saying FC=$F77. Perhaps the documentation at the above link makes more sense to you since you are working on the make files right now.
