 Message        <Context> the enumerator "<name>" is not unique.

 Description    An enumerator constant is declared more than once
                with the same value.  While this is accepted by
                Compaq C, it is not allowed by the C standard.

 User Action    Either use a different enumerator name or remove the
                previous declaration of the name.
