	* sem_aggr.adb (Resolve_Record_Aggregate): If
	Warn_On_Redundant_Constructs is enabled, report a redundant box
	association that does not cover any components, as it done for
	redundant others associations in case statements.

	* sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
	Analyze the generated Check pragma for an inherited condition so
	that it does not freeze the dispatching type of the primitive
	operation, because it is pre-analyzed at the point of the
	subprogram declaration (and not in the subprogram body, as is
	done during regular expansion).

	* ali.ads: Increase the range of all _Id types to 100 millions.

	* sem_warn.adb (Check_References): Change warning to suggest
	using pragma Export rather than saying "volatile has no effect".

	* exp_intr.ads (Add_Source_Info): Improve documentation.
	* sem_intr.adb (Check_Intrinsic_Subprogram): Recognize
