9327 c-common.c's pseudo-typedefs that wind up in the external scope.
9328 (lookup_name_current_level): Rename lookup_name_in_scope; take a
9329 second argument indicating the scope to examine; rewrite for
9330 new bindings structures.
9331 (c_init_decl_processing): Adjust for renamed functions. Do not
9332 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
9333 First scope pushed is the external scope, not the global scope.

9344 (finish_struct, finish_enum): Remove redundant diagnostics.
9345 (build_enumerator): Don't cascade diagnostics for error_mark_node.
9346 Mark location where -pedantic changes the meaning of the program.

9377 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
9378 correct loop over multiple translation units; call fatal_error if
9379 requested to compile more than one file at once. (This disables
9380 IMA temporarily - an up-front error being preferable to a crash.)
9381 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
9382 (all actions): Adjust calls to pushlevel/poplevel.
9383 (parsing_iso_function_signature): Delete.

9392 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
9393 to suppress -Wold-style-definition after this error.
9394 (c_parse_file): Don't clear the binding stack or call
9395 finish_fname_decls here. Correct comment.
9396 * c-typeck.c (same_translation_unit_p): Export.

14165 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
14166 (_cpp_lex_direct): Use linemap_position_for_column.
14167 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
