 Message        The member alignment popped/restored with pragma
                <pragma name> was saved using pragma <pragma name>.
                The member alignment restored will take effect.

 Description    Compaq C supports two forms of the member alignment
                directives.  One begins with #pragma pack, the other
                with #pragma member_alignment.  A program has mixed
                the pack and the member_alignment form of the
                directives in a way that is not recommended.  This
                might indicate a programming error.

 User Action    If a member alignment has been saved by one form of
                the member-alignment directive, it should be restored
                by the same form of the directive.
