Thanks, I installed the following patch.  I'm CC:ing this to Wendy
Palm, who submitted Cray-related patches earlier this year, in case
there's some reason to still keep trying to use those ancient
compilers.

        * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
        from the default list of compilers to try.  Suggested by
        Kate Hedstrom.
        * NEWS: Document the above.
        * autoconf.texi: Don't suggest cf77.
