        * parser.c (declarator_can_be_parameter_pack): New.
        (cp_parser_template_parameter): Only parse the `...' if the
        declarator can be a parameter pack.
        (cp_parser_parameter_declaration): Ditto. Also, handle when TYPE
        is NULL.
        * pt.c (find_parameter_packs_r): Look into the bounds on integer
        types (they could be used as array bounds). 
        (check_for_bare_parameter_packs): Deal with TEMPLATE_PARM_INDEX.
        (tsubst_pack_expansion): Handle failure to expand parameter
        packs.
