        * c-decl.c (finish_struct):  Only set DECL_PACKED on a field
        when its natural alignment is > BITS_PER_UNIT.
        * stor-layout.c (finalize_type_size): Revert my patch of 2005-08-08.
        * c-common.c (handle_packed_attribute): Ignore packing on a field
        whose type is naturally char aligned.
