The above indicates that the C compiler "/opt/ansic/bin/cc" couldn't
compile the following code (file "conftest.c"):

    void sub(values)
        signed char values[4];
    {
        exit(values[1] != -2 || values[2] != -3);
    }

The compiler choked on the "signed" keyword above.  This indicates
that the compiler is not a Standard C compiler (regardless of what the
pathname connotes).  The netCDF package is designed to be compiled with
a Standard C compiler.

Unfortunately, we no longer have an HP-UX B.10.20 system, so I can't
duplicate your problem to find a workaround.  (The /opt/ansic/bin/cc"
compiler that we have on our HP-UX B.11.00 system successfully compiled
the above code.)

You might try one of the following:

    1.  See if /opt/ansic/bin/cc has an option that will cause "signed"
        to be accepted and set that option in the CFLAGS environment
        variable.

    2.  Use the set of environment variables indicated in the INSTALL
        file for HP-UX B.10.20 (i.e. don't use /opt/ansic/bin/cc).

    3.  Use /opt/ansic/bin/c89 instead of /opt/ansic/bin/cc.

Each of the above options will require you to execute steps 2 through 6
near the end of the INSTALL file.

Please let me know if this helps.
