	c-common.c's pseudo-typedefs that wind up in the external scope.
	(lookup_name_current_level): Rename lookup_name_in_scope; take a
	second argument indicating the scope to examine; rewrite for
	new bindings structures.
	(c_init_decl_processing): Adjust for renamed functions.  Do not
	initialize current_file_decl, first_builtin_decl, last_builtin_decl.
	First scope pushed is the external scope, not the global scope.
	(builtin_function): Use bind, not pushdecl.  Adjust other bits
	for new data structures.  Keep track of builtins that should be
	made visible automatically.
	(start_decl): Adjust diagnostics.  Remove unnecessary call to
	expand_decl.
	(grokparms): Return 0 if arg_types is error_mark_node.
	(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.
	(finish_struct, finish_enum): Remove redundant diagnostics.
	(build_enumerator): Don't cascade diagnostics for error_mark_node.
	Mark location where -pedantic changes the meaning of the program.
	(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
	parameter decls into the function's scope structure using bind.
	Warn here about function definitions in the wrong style.
	Adjust diagnostics.
	(store_parm_decls): Correct the determination of whether a
	function was defined with a prototype.
	(c_write_global_declarations): Operate on all file decls and on
	the external scope.  Split body of the loop to...

	* 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.
	(all actions): Adjust calls to pushlevel/poplevel.
	(parsing_iso_function_signature): Delete.
	(extdef_1): Fold into extdef.
	(old_style_parm_decls_1): Fold into old_style_parm_decls.  Don't
	warn here about function definitions in the wrong style.
	(after_tyle_declarator, parm_declarator_starttypename)
	(parm_declarator_nostarttypename, notype_declarator): Remove
	commented-out productions.
	(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
	an empty TREE_LIST node.  Adjust calls to get_parm_info.
	(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
	to suppress -Wold-style-definition after this error.
	(c_parse_file): Don't clear the binding stack or call
	finish_fname_decls here.  Correct comment.
	* c-typeck.c (same_translation_unit_p): Export.
	(common_type): Use c_override_global_bindings_to_false, not
	pushlevel/poplevel/declare_parm_level.
	* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
	LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,

	(generate_forward_declaration_to_string_table): Delete.
	* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.

	* langhooks.c (lhd_clear_binding_stack): Call
	lang_hooks.decls.poplevel, not poplevel.
	* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
