 Message        Invalid register "<register>" for linkage pragma.
                Pragma is ignored.

 Description    The compiler encountered bad register specifier in a
                #pragma linkage directive.  The message should point
                at the offending specifier.  The compiler will ignore
                the entire pragma.

 User Action    Correct the directive.
