I thought I was forced to use AC_PROG_F77 since when I used AC_PROG_FC instead, I was

hoping AC_FC_SRCEXT([f]) would help, but I didn't get my hopes up and validated it didn't
work as hoped. Yes, it is technically Fortran 77 source, but why can't I use AC_PROG_FC
in lieu of AC_PROG_F77 without complaints?
Note that this is an automake problem, not an autoconf problem.
(I agree that AC_FC_SRCEXT(f) should be used by automake as an
indication to use FC for .f files rather than F77; I suggested this on
the automake list back in 2005, but perhaps the suggestion should be
repeated.)
