2008-05-28  Robert Dewar  <dewar@adacore.com>

	* restrict.ads:
	Add missing restrictions, and properly label all GNAT defined ones
	
	* rtsfind.ads:
	Add entry for Ada_Real_Time.Timing_Events.Timing_Event
	Add entry for Ada.Task_Termination.Set_Specific_Handler
	Add entry for Ada.Task_Termination.Specific_Handler
	
	* s-rident.ads:
	Add missing restrictions and properly mark all gnat defined ones
	
	* sem_ch3.adb:
	(Analyze_Object_Declaration): Check No_Local_Timing_Events restriction
	
	* sem_res.adb:
	(Resolve_Call): Check violation of No_Specific_Termination_Handlers

	* gnat_rm.texi: Add missing restrictions, and properly label all
	GNAT defined ones
