        * cp-tree.h (NON_DEFAULT_TEMPLATE_ARGS_COUNT,
        SET_NON_DEFAULT_TEMPLATE_ARGS_COUNT,
        GET_NON_DEFAULT_TEMPLATE_ARGS_COUNT): New accessor macros.
        * pt.c (coerce_template_parms, type_unification_real,
        expand_template_argument_pack, coerce_template_parameter_pack):
        Set the non default template args count.
        (current_template_args): Always set non defaulted
        template args count when compiled with --enable-checking
        (tsubst_template_args, type_unification_real): Propagate the non
        defaulted template args count.
        * error.c (get_non_default_template_args_count): Renamed
        count_non_default_template_args into this. Don't calculate the
        non default template argument count anymore. Use the new
        accessor macros above to get it.
        (dump_template_argument_list, dump_type, dump_decl,
        dump_template_parms): Adjust.
        * parser.c (cp_parser_template_argument_list): Always set defaulted
        template args count when compiled with --enable-checking.
