 Message        This typedef declaration is useless because it does
                not declare a typedef name.

 Description    This typedef declaration does not declare a typedef
                name.  This case can occur when a declaration tries
                to declare both a tag and a typedef, but the name of
                the typedef is not included.

 User Action    Either remove the typedef keyword or add a typedef
                name.
