6339 (grokparms): Return 0 if arg_types is error_mark_node.
6340 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with

6344 (finish_struct, finish_enum): Remove redundant diagnostics.
6345 (build_enumerator): Don't cascade diagnostics for error_mark_node.
6346 Mark location where -pedantic changes the meaning of the program.

6377 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
6378 correct loop over multiple translation units; call fatal_error if
6379 requested to compile more than one file at once. (This disables
6380 IMA temporarily - an up-front error being preferable to a crash.)
6381 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
6382 (all actions): Adjust calls to pushlevel/poplevel.
6383 (parsing_iso_function_signature): Delete.

6393 to suppress -Wold-style-definition after this error.

11166 (_cpp_lex_direct): Use linemap_position_for_column.
11167 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
