	(c_print_identifier): Update for changes to struct lang_identifier.
	(objc_mark_locals_volatile): Update for new bindings structures.
	(global_bindings_p): Honor c_override_global_bindings_to_false.

	scope_freelist; initialize scope->depth and check for overflow.
	(poplevel): Rename to pop_scope; totally rewritten for new bindings
	structures.
	(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
	C_DECL_INVISIBLE, for certain decisions.  Adjust some diagnostics.
	Improve some commentary.  Adjust handling of forward parm decls.
	(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
	Preserve C_DECL_IN_EXTERNAL_SCOPE.

	decls.  Rewrite for new bindings structures.  Improve commentary.
	Eliminate the copy_node call.
	(implicit_decl_warning): Use the "diag" idiom (as seen in
	locate_old_decl) to reduce code duplication; call locate_old_decl
	if appropriate.  Relocate to remove need for forward declaration.
	(implicitly_declare): Adjust for new bindings structures.  Kludge
	around Objective-C not-really-builtin functions.
	(undeclared_variable): Improve diagnostics.  If current_function_decl
	is nonnull but current_function_scope is null, use current_scope.
	Use bind.
	(lookup_tag): Adjust for new bindings structures.  Kludge around
	Objective-C's tag declarations that wind up in the external scope.
	(lookup_name): Adjust for new bindings structures.  Kludge around
	c-common.c's pseudo-typedefs that wind up in the external scope.

	(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
	reversed sense.  Rewrite for new bindings structures.  Do not
	leave any decls in the scope, to prevent pop_scope from doing
	contradictory things with them.

	(mark_forward_parm_decls, build_compound_literal)
	(grokdeclarator, start_function, check_for_loop_decls)
	(identifier_global_value, record_builtin_type): Minor adjustments
	for new bindings structures.  Improve diagnostics and commentary.
	* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
	pushlevel/poplevel respectively.
	(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
	* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
	Warn about YYDEBUG not being defined only if -dy.  Remove no-longer-
	correct loop over multiple translation units; call fatal_error if
	requested to compile more than one file at once.  (This disables
	IMA temporarily - an up-front error being preferable to a crash.)
	* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.

	commented-out productions.
	(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
