 Message        The register "<register>" is specified more than once
                in the linkage pragma.  Pragma is ignored.

 Description    The same register was specified more than once in the
                same register list in a #pragma linkage directive.
                The compiler will ignore the entire pragma.

 User Action    Correct the directive.
