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.)
