1376 (implicit_decl_warning): Use the "diag" idiom (as seen in
1377 locate_old_decl) to reduce code duplication; call locate_old_decl
1378 if appropriate. Relocate to remove need for forward declaration.
1379 (implicitly_declare): Adjust for new bindings structures. Kludge
1380 around Objective-C not-really-builtin functions.
1381 (undeclared_variable): Improve diagnostics. If current_function_decl
1382 is nonnull but current_function_scope is null, use current_scope.
1384 (lookup_tag): Adjust for new bindings structures. Kludge around
1385 Objective-C's tag declarations that wind up in the external scope.

1387 c-common.c's pseudo-typedefs that wind up in the external scope.
1388 (lookup_name_current_level): Rename lookup_name_in_scope; take a
1389 second argument indicating the scope to examine; rewrite for
1390 new bindings structures.
1391 (c_init_decl_processing): Adjust for renamed functions. Do not
1392 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
1393 First scope pushed is the external scope, not the global scope.
1394 (builtin_function): Use bind, not pushdecl. Adjust other bits
1395 for new data structures. Keep track of builtins that should be
1396 made visible automatically.
1397 (start_decl): Adjust diagnostics. Remove unnecessary call to
1399 (grokparms): Return 0 if arg_types is error_mark_node.
1400 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
1401 reversed sense. Rewrite for new bindings structures. Do not
1402 leave any decls in the scope, to prevent pop_scope from doing
1403 contradictory things with them.
1404 (finish_struct, finish_enum): Remove redundant diagnostics.
1405 (build_enumerator): Don't cascade diagnostics for error_mark_node.
1406 Mark location where -pedantic changes the meaning of the program.

1414 the external scope. Split body of the loop to...

1436 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
1437 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1438 correct loop over multiple translation units; call fatal_error if
1439 requested to compile more than one file at once. (This disables
1440 IMA temporarily - an up-front error being preferable to a crash.)
1441 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1442 (all actions): Adjust calls to pushlevel/poplevel.
1443 (parsing_iso_function_signature): Delete.
1444 (extdef_1): Fold into extdef.
1445 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

1448 (parm_declarator_nostarttypename, notype_declarator): Remove
1449 commented-out productions.
1450 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
1451 an empty TREE_LIST node. Adjust calls to get_parm_info.
1452 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
1453 to suppress -Wold-style-definition after this error.
1454 (c_parse_file): Don't clear the binding stack or call
1455 finish_fname_decls here. Correct comment.
1456 * c-typeck.c (same_translation_unit_p): Export.
