1375 around Objective-C not-really-builtin functions.
1376 (undeclared_variable): Improve diagnostics. If current_function_decl
1377 is nonnull but current_function_scope is null, use current_scope.
1379 (lookup_tag): Adjust for new bindings structures. Kludge around
1380 Objective-C's tag declarations that wind up in the external scope.

1382 c-common.c's pseudo-typedefs that wind up in the external scope.
1383 (lookup_name_current_level): Rename lookup_name_in_scope; take a
1384 second argument indicating the scope to examine; rewrite for
1385 new bindings structures.
1386 (c_init_decl_processing): Adjust for renamed functions. Do not
1387 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
1388 First scope pushed is the external scope, not the global scope.
1389 (builtin_function): Use bind, not pushdecl. Adjust other bits
1390 for new data structures. Keep track of builtins that should be
1391 made visible automatically.
1392 (start_decl): Adjust diagnostics. Remove unnecessary call to
1394 (grokparms): Return 0 if arg_types is error_mark_node.
1395 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
1396 reversed sense. Rewrite for new bindings structures. Do not
1397 leave any decls in the scope, to prevent pop_scope from doing
1398 contradictory things with them.
1399 (finish_struct, finish_enum): Remove redundant diagnostics.
1400 (build_enumerator): Don't cascade diagnostics for error_mark_node.
1401 Mark location where -pedantic changes the meaning of the program.

1431 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
1432 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1433 correct loop over multiple translation units; call fatal_error if
1434 requested to compile more than one file at once. (This disables
1435 IMA temporarily - an up-front error being preferable to a crash.)
1436 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1437 (all actions): Adjust calls to pushlevel/poplevel.
1438 (parsing_iso_function_signature): Delete.
1439 (extdef_1): Fold into extdef.

1444 commented-out productions.

1446 an empty TREE_LIST node. Adjust calls to get_parm_info.
1447 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
1448 to suppress -Wold-style-definition after this error.
1449 (c_parse_file): Don't clear the binding stack or call
1450 finish_fname_decls here. Correct comment.
1451 * c-typeck.c (same_translation_unit_p): Export.
