Thanks for the suggestion.  I think the fc Fortran compiler is long
dead, so I installed this patch.

2002-08-17  Paul Eggert  <address@hidden>

        * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
        default list of compilers to try, since it was long ago superseded
        by the ksh fc builtin.  Suggested by Steven G. Johnson.
