462 (implicit_decl_warning): Use the "diag" idiom (as seen in
463 locate_old_decl) to reduce code duplication; call locate_old_decl
464 if appropriate. Relocate to remove need for forward declaration.
465 (implicitly_declare): Adjust for new bindings structures. Kludge
466 around Objective-C not-really-builtin functions.
467 (undeclared_variable): Improve diagnostics. If current_function_decl
468 is nonnull but current_function_scope is null, use current_scope.
470 (lookup_tag): Adjust for new bindings structures. Kludge around
471 Objective-C's tag declarations that wind up in the external scope.
472 (lookup_name): Adjust for new bindings structures. Kludge around
473 c-common.c's pseudo-typedefs that wind up in the external scope.
474 (lookup_name_current_level): Rename lookup_name_in_scope; take a
475 second argument indicating the scope to examine; rewrite for
476 new bindings structures.
477 (c_init_decl_processing): Adjust for renamed functions. Do not
478 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
479 First scope pushed is the external scope, not the global scope.
480 (builtin_function): Use bind, not pushdecl. Adjust other bits
481 for new data structures. Keep track of builtins that should be
482 made visible automatically.
483 (start_decl): Adjust diagnostics. Remove unnecessary call to
485 (grokparms): Return 0 if arg_types is error_mark_node.
486 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
487 reversed sense. Rewrite for new bindings structures. Do not
488 leave any decls in the scope, to prevent pop_scope from doing
489 contradictory things with them.
490 (finish_struct, finish_enum): Remove redundant diagnostics.
491 (build_enumerator): Don't cascade diagnostics for error_mark_node.
492 Mark location where -pedantic changes the meaning of the program.

498 function was defined with a prototype.
499 (c_write_global_declarations): Operate on all file decls and on
500 the external scope. Split body of the loop to...

522 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
523 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
524 correct loop over multiple translation units; call fatal_error if
525 requested to compile more than one file at once. (This disables
526 IMA temporarily - an up-front error being preferable to a crash.)
527 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
528 (all actions): Adjust calls to pushlevel/poplevel.
529 (parsing_iso_function_signature): Delete.
530 (extdef_1): Fold into extdef.
531 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
532 warn here about function definitions in the wrong style.

534 (parm_declarator_nostarttypename, notype_declarator): Remove
535 commented-out productions.

537 an empty TREE_LIST node. Adjust calls to get_parm_info.
538 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
539 to suppress -Wold-style-definition after this error.
540 (c_parse_file): Don't clear the binding stack or call
541 finish_fname_decls here. Correct comment.
542 * c-typeck.c (same_translation_unit_p): Export.
543 (common_type): Use c_override_global_bindings_to_false, not
