	* freeze.adb (Build_Inherited_Condition_Pragmas): New procedure,
	subsidiary of Check_Inherited_Conditions, to build pragmas for an
	operation whose ancestor has classwide pre/postconditions. This
	is used both to check the legality of the inheritance in Ada
	and in SPARK, and to determine whether a wrapper is needed for
	an inherited operation.
	* exp_util.adb (Build_Class_Wide_Expression, Replace_Entity):
	Improve placement of error message for inherited classwide
	conditions that become illegal on type derivation.

	* sem_ch12.adb (Analyze_Generic_Package_Declaration): Set
	SPARK_Mode from context on generic package.
	* sem_ch7.adb (Analyze_Package_Declaration): Simplify code to remove
	useless test.

	* a-cofuve.ads (Range_Shifted): Rewrite precondition to avoid
	overflows in computations.

	overflows in computations.
	(Insert): Rewrite precondition to avoid overflows in computations.
	* a-cfinve.ads (Capacity_Range): Rewrite last bound to avoid
