        * c-warn.c (check_alignment_of_packed_member): Add a boolean parameter
        for rvalue context.  Handle rvalues correctly.  Use min_align_of_type
        instead of TYPE_ALIGN.
        (check_address_or_pointer_of_packed_member): Handle rvalues coorrectly.
        Use min_align_of_type instead of TYPE_ALIGN_UNIT.  Check for NULL
