	* sem_warn.adb (Warn_On_Unreferenced_Entity): If the entity is an
	Out_Parameter the front-end does not emit any warning on it, so
	do not suppress warnings on the entity because the backend might
	be able to determine an uninitialized path and warn accordingly.

	* exp_ch6.adb (Is_Build_In_Place_Function_Call):
	Test Expression (N) in N_Type_Conversion cases as well,

	(Make_Build_In_Place_Call_In_Anonymous_Context): Retrieve
	function call from Expression (Func_Call) when Nkind (Func_Call)
	is N_Type_Conversion, since conversions are allowed in "anonymous"
	contexts (specifically, as actual parameters).
