472 (scope_freelist): Move to more appropriate location.
473 (c_print_identifier): Update for changes to struct lang_identifier.
474 (objc_mark_locals_volatile): Update for new bindings structures.
475 (global_bindings_p): Honor c_override_global_bindings_to_false.
476 (pushlevel): Rename to push_scope; take no arguments; use the
477 scope_freelist; initialize scope->depth and check for overflow.
478 (poplevel): Rename to pop_scope; totally rewritten for new bindings
480 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
481 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
482 Improve some commentary. Adjust handling of forward parm decls.
483 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
484 Preserve C_DECL_IN_EXTERNAL_SCOPE.
485 (warn_if_shadowing): Correct indentation. Improve diagnostics.
486 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
487 decls. Rewrite for new bindings structures. Improve commentary.
488 Eliminate the copy_node call.
489 (implicit_decl_warning): Use the "diag" idiom (as seen in
490 locate_old_decl) to reduce code duplication; call locate_old_decl
491 if appropriate. Relocate to remove need for forward declaration.

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

508 for new data structures. Keep track of builtins that should be
509 made visible automatically.
510 (start_decl): Adjust diagnostics. Remove unnecessary call to
512 (grokparms): Return 0 if arg_types is error_mark_node.
513 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
514 reversed sense. Rewrite for new bindings structures. Do not
515 leave any decls in the scope, to prevent pop_scope from doing
516 contradictory things with them.
517 (finish_struct, finish_enum): Remove redundant diagnostics.
518 (build_enumerator): Don't cascade diagnostics for error_mark_node.
519 Mark location where -pedantic changes the meaning of the program.

553 IMA temporarily - an up-front error being preferable to a crash.)
554 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
555 (all actions): Adjust calls to pushlevel/poplevel.
556 (parsing_iso_function_signature): Delete.

568 finish_fname_decls here. Correct comment.
569 * c-typeck.c (same_translation_unit_p): Export.
