	* exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
	"Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
	does not exist in the Ada RM.
	(Compatible_Int_Bounds): Determine whether two integer range bounds
	are of equal length and have the same start and end values.
	(Is_Int_Range_Bounds): Determine whether a node is an integer range.
	(Build_Record_Aggr_Code): Perform proper sliding of a nested array
	aggregate when it is part of an object declaration.
	(Build_Record_Aggr_Code)  If the aggregate ttype is a derived type that
	constrains discriminants of its parent, add explicitly the discriminant
	constraints of the ancestor by retrieving them from the
	stored_constraint of the parent.
