 Message        A bad use_linkage pragma was specified.  Pragma is
                ignored.

 Description    The compiler encountered a bad #pragma use_linkage
                directive.  The error message should point to the
                place in the pragma that the compiler considers bad.
                The compiler will ignore the entire pragma.

 User Action    Correct the directive.
