 Message        An additional <number> bytes of padding have been
                implicitly inserted prior to this member for proper
                alignment of this member.

 Description    The compiler has added pad bytes before a member so
                that it will be accessed efficiently.  This might not
                have been what you intended.

 User Action    Consider rearranging the order of member
                declarations.
