	* adabkend.adb (Call_Back_End): Fix wording of "front-end" and
	"back-end" in comments.

	* exp_ch6.adb (Expand_Call_Helper): The extra accessibility check in a
	call that appears in a classwide precondition and that mentions an
	access formal of the subprogram, must use the accessibility level of
	the actual in the call. This is one case in which a reference to a
	formal parameter appears outside of the body of the subprogram.
