	* exp_attr.adb (May_Be_External_Call): Remove this. There is no need
	for the compiler to guess whether the call is internal or external --
	it is always external.
	(Expand_Access_To_Protected_Op): For P'Access, where P
	is a protected subprogram, always create a pointer to the
	External_Subprogram.
