1380 (warn_if_shadowing): Correct indentation. Improve diagnostics.
1381 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
1382 decls. Rewrite for new bindings structures. Improve commentary.
1383 Eliminate the copy_node call.
1384 (implicit_decl_warning): Use the "diag" idiom (as seen in
1385 locate_old_decl) to reduce code duplication; call locate_old_decl
1386 if appropriate. Relocate to remove need for forward declaration.
1387 (implicitly_declare): Adjust for new bindings structures. Kludge
1388 around Objective-C not-really-builtin functions.
1389 (undeclared_variable): Improve diagnostics. If current_function_decl
1390 is nonnull but current_function_scope is null, use current_scope.
1392 (lookup_tag): Adjust for new bindings structures. Kludge around
1393 Objective-C's tag declarations that wind up in the external scope.

1395 c-common.c's pseudo-typedefs that wind up in the external scope.
1396 (lookup_name_current_level): Rename lookup_name_in_scope; take a
1397 second argument indicating the scope to examine; rewrite for
1398 new bindings structures.
1399 (c_init_decl_processing): Adjust for renamed functions. Do not
1400 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
1401 First scope pushed is the external scope, not the global scope.
1402 (builtin_function): Use bind, not pushdecl. Adjust other bits
1403 for new data structures. Keep track of builtins that should be
1404 made visible automatically.
1405 (start_decl): Adjust diagnostics. Remove unnecessary call to
1407 (grokparms): Return 0 if arg_types is error_mark_node.
1408 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
1409 reversed sense. Rewrite for new bindings structures. Do not
1410 leave any decls in the scope, to prevent pop_scope from doing
1411 contradictory things with them.
1412 (finish_struct, finish_enum): Remove redundant diagnostics.
1413 (build_enumerator): Don't cascade diagnostics for error_mark_node.
1414 Mark location where -pedantic changes the meaning of the program.

1444 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
1445 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1446 correct loop over multiple translation units; call fatal_error if
1447 requested to compile more than one file at once. (This disables
1448 IMA temporarily - an up-front error being preferable to a crash.)
1449 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1450 (all actions): Adjust calls to pushlevel/poplevel.
1451 (parsing_iso_function_signature): Delete.
1452 (extdef_1): Fold into extdef.

1457 commented-out productions.

1459 an empty TREE_LIST node. Adjust calls to get_parm_info.
1460 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
1461 to suppress -Wold-style-definition after this error.
1462 (c_parse_file): Don't clear the binding stack or call
1463 finish_fname_decls here. Correct comment.
1464 * c-typeck.c (same_translation_unit_p): Export.
