	* c-common.h (enum rid): Add RID_AT_PACKAGE.
	(objc_ivar_visibility_kind): New enum.
	(objc_set_visibility): Adjust prototype to use visibility enum.
	* stub-objc.c (objc_set_visibility): Adjust stub to use 
	visibility enum.

gcc/objc:

	* objc-act.c: Rename 'objc_public_flag' to  objc_ivar_visibility and
	make its type 'objc_ivar_visibility_kind'.  
	(objc_start_class_interface): Update to use visibility enum.
	(objc_start_class_implementation): Likewise.
	(objc_set_visibility): Update to use visibility enum, warn that 
	@package is handle as per @public.
	(add_instance_variable): Handle OBJC_IVAR_VIS_PACKAGE.
	* objc-act.h: Rename 'objc_public_flag' to  objc_ivar_visibility and
	make its type 'objc_ivar_visibility_kind'.

gcc/cp:

	* parser.c (cp_parser_objc_visibility_spec): Update to use visibility 
	enum, and handle @package.

gcc:

	* c-parser.c (c_parser_objc_class_instance_variables): Update to use
