9333 (grokparms): Return 0 if arg_types is error_mark_node.
9334 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
9335 reversed sense. Rewrite for new bindings structures. Do not

9338 (finish_struct, finish_enum): Remove redundant diagnostics.
9339 (build_enumerator): Don't cascade diagnostics for error_mark_node.
9340 Mark location where -pedantic changes the meaning of the program.

9371 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
9372 correct loop over multiple translation units; call fatal_error if
9373 requested to compile more than one file at once. (This disables
9374 IMA temporarily - an up-front error being preferable to a crash.)
9375 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
9376 (all actions): Adjust calls to pushlevel/poplevel.
9377 (parsing_iso_function_signature): Delete.

9387 to suppress -Wold-style-definition after this error.

14159 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
14160 (_cpp_lex_direct): Use linemap_position_for_column.
14161 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
14162 parameter. Instead get it from the line_table global. Adjust callers.
