   BIGGEST_ALIGNMENT <= POINTER_SIZE to trigger the warning, as

   otherwise the offset of 'a' (i.e. POINTER_SIZE) is split into a

   non-zero DECL_FIELD_OFFSET and a zero DECL_FIELD_BIT_OFFSET,

   and then there is no discrepancy between DECL_FIELD_OFFSET and

   byte_position to warn about.  */
