There are a number of places where FC appears, so you'll need to fix 
those if you eliminate the substitution.

Maybe it would be best to use FC consistently instead of F77, including 
using the AC_PROG_FC macro instead of F77?  I'm not sure of the 
implications though.

So another option is to leave things alone as they seem to be working.
