I didn't see anything in "config.log" that would indicate a problem.

Whoa!  The Fortran "byte" type doesn't correspond to any C type!?

And the same goes for "integer*2", "integer", "real", and
"doubleprecision"?!

Needless to say, your Fortran interface will be useless because there
will be no way to convert between Fortran data types and the C data
types used in the underlying library.  This is probably the cause of the
segmentation fault during execution of the "make test" in the nf_test/
subdirectory.

This doesn't happen on our system:

    $ uname -a
    Linux sunshine.unidata.ucar.edu 2.2.13 #5 SMP Mon Nov 29 12:41:02 MST 1999 
i686 unknown

We'll need to discover why it happens on yours.

On our system, the "fort77" compiler's pathname is "/opt/bin/fort77"
while on your system it's "/usr/bin/fort77".  I wonder if they're the
same compiler.  Here's our version:

    $ fort77 -v
    /opt/bin/fort77: fort77 Version 1.14a
    /opt/bin/fort77: No input files specified

What's your version?
