 Message        An unnamed member does not have a bitfield, struct,
                or union type.  Member is ignored.

 Description    An unnamed member of a struct or union type has no
                meaning unless it is a bitfield or a struct/union
                type.  The compiler will ignore this member.

 User Action    If the member is desired, give it a name.  Otherwise
                remove the unnamed member.
