It appears that the configure script thinks that it's impossible
to build the Fortran interface *at all*.

I think some questions are in order:

    1.  Do you need the Fortran interface?

    2.  If so, then
    
        A.  What are the Fortran types that are equivalent to the
            following C types:

                signed char
                short
                int
                long
                float
                double

        B.  Would you please send me a copy of the file "config.log" 
            in the top-level source directory.
