	* exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
	accessibility check to an interface conversion, whose purpose
	is to perform a pointer adjustment in a dispatching call.
	* exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
	when the actual is a construct that involves a dereference of an
	expression that includes a formal of the enclosing subprogram,
	In such cases, the accessibility level of the actual is that of
	the corresponding formal, which is passed in as an additional
	actual in the outer call.
