In order to build the FORTRAN interface to the netCDF library
using LAHEY FORTRAN 90, you must have a `.m4' file in the fortran/
subdirectory (e.g. lahey.m4) which details the conventions used by a
FORTRAN routine when it calls a C function (the conventions differ
from system to system).  This file is used by the `sed' utility in
fortran/Makefile to generate appropriate FORTRAN interface code.

Because I don't have access to your environment, you will have to
determine the FORTRAN-to-C conventions for your system.  We should then
be able to generate the necessary `.m4' file and FORTRAN code.

Would you please determine the following:

    1.  What are the FORTRAN types that correspond to the following C
        types:

            char
            short
            int
            long
            float
            double

    2.  Are your C `char's signed or unsigned?

    3.  How does a FORTRAN routine pass a CHARACTER variable to a C
        routine?  A very common way is for the FORTRAN routine to add an
        extra argument for every CHARACTER variable argument.  This
        extra argument contains the length of the associated CHARACTER
        variable.

You might be able to find this information in your LAHEY FORTRAN User's
Guide.
