	* sem_ch3.adb (Analyze_Object_Declaration): Add a missing check
	for optimized aggregate arrays with qualified expressions.
	* exp_aggr.adb (Expand_Array_Aggregate): Fix block and
	conditional statement in charge of deciding whether to perform
	in-place expansion. Specifically, use Parent_Node to jump over
	the qualified expression to the object declaration node. Also,
	a check has been inserted to skip the optimization if SPARK 2005
	is being used in strict adherence to RM 4.3(5).

	* sem_prag.adb (Analyze_Pragma): Simplify code
	for Pragma_Priority.
