Hmm...  To answer your question definitively, I would have to know
what the g77-to-gcc calling conventions are -- and I don't.  On the
assumption that they are the same as the f2c-to-gcc calling conventions,
I suggest trying the following:

    1.  Go to the top-level source directory of the netCDF-3 package.

    2.  Execute the command "make distclean".

    3.  Ensure that the file "config.cache" has been removed.

    4.  Include "-Df2cFortran" in the setting of the environment variable
        CPPFLAGS, e.g.

            CPPFLAGS='-Df2cFortran -DNDEBUG'

    5.  Execute the configure script.

    6.  Execute the command "make".

Another value that you might try in step 4 above is "sunFortran".

Please let me know if this helps.
