The FORTRAN API is tested in the fortran/ subdirectory by the FORTRAN
test program `ftest.f'.  This program is created from the file
`ftest.src' by the same process that creates the files `netcdf.inc' and
`jackets.c'.  The process didn't work for those files because of the
broken m4(1) utility, so it doesn't work for `ftest.f' either.

I'm sending you an appropriate `ftest.f' file in another message.  If
you put it in the fortran/ subdirectory, then the `make test' should
work.

Be very careful about executing the command `make clean'.  It will
remove all the files that I sent you.

This is good.

The above messages may be safely ignored.

This is also good.

It looks like you're almost done.  The remaining steps are

    1.  Testing the FORTRAN API using the file `ftest.f' that will come
        in another message.

    2.  Installing the netCDF package by executing the command `make
        install' from the top-level source directory.

    3.  Cleaning up by executing the command `make clean' from the
        top-level source directory.  NOTE: This command will remove
        the fortran/ subdirectory files that I sent you: `netcdf.inc',
        `jackets.c', and `ftest.f'.  You should probably save these
        files before executing the command.

Yes, I am.  Thanks.
