        * typeck.c (check_return_expr): If there are bare parameter packs
        in the return value, set it to error_mark_node.
        * tree.c (cp_walk_subtrees): Walk USING_DECL nodes.
        * pt.c (find_parameter_packs_r): Look at the type of
        IDENTIFIER_NODEs (e.g., for user-defined conversions).
        (check_for_bare_parameter_packs): Flip the result: now returns
        TRUE when there were bare parameter packs, FALSE otherwise.
        (push_template_decl_real): Deal with flipped result of
        check_for_bare_parameter_packs.
        * semantics.c (finish_cond): If there are bare parameter packs in
        the conditional, set it to error_mark_node.
        (finish_expr_stmt): If there are bare parameter packs in the
        expression, set it to error_mark_node.
        (finish_for_expr): Ditto.
        (finish_switch_cond): If there are bare parameter packs in
        the conditional, set it to error_mark_node.
        (finish_mem_initializers): If there are bare parameter packs in
        the member initializer, set it to error_mark_node.
        (finish_member_declaration): Check the attributes of the
        declaration for bare parameter packs, and remove the attributes if
        any have bare parameter packs.
        * parser.c (cp_parser_using_declaration): Check the using
        declaration for bare parameter packs.
        (cp_parser_base_clause): If there are bare parameter packs in a
        base specifier, don't add it to the chain.
