Message        The declaration of a member that is an unnamed struct
                or union type is an extension and might not be
                portable.

 Description    VSI C allows a member of a struct or union to be an
                unnamed struct or union type.  This is an extension
                of VSI C that other compilers might not support.  In
                addition this behavior does not conform to the C
                standard.

 User Action    If portability is desired, provide a name for the
                struct/union member.
