Having autoconf search for gfortran

[Ulf Lorenz]

Hi,

I had a look at the autoconf documentation, and there seems to be a
simple fix for the issue of spoon-feeding autoconf the fact that you
have gfortran installed. Actually, there are two:

1. In configure.ac, use the macro AC_PROG_FC to denote that you are not
interested in a Fortran-77, but any Fortran compiler. Has some
disadvantages, though (might not be what you want, and some other
macros need tweaking).

2. Add the gfortran compiler in the search list, i.e., change line 83
of configure.ac to

AC_PROG_F77([f77 gfortran])

I would vote for the second option. Since gfortran knows a superset of
Fortran-77 and is the default Fortran compiler at least for Debian
(probably other Linux distros as well), that should be in for
convenience.

I do not have gfortran around. Could you test it? If it works, we add it.

Well, I always had to supply the F77=gfortran flag, and this works
indeed fine.

Done!
