	* sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
	not try to rewrite a renamed stream attribute, because the operations
	on the type may not have been generated.
	Handle properly a renaming_as_body generated for a stream operation
	whose default is abstract because the object type itself is abstract.
	(Find_Type): If the type is incomplete and appears as the prefix of a
	'Class reference, it is tagged, and its list of primitive operations
	must be initialized properly.
	(Chain_Use_Clauses): When chaining the use clauses that appear in the
	private declaration of a parent unit, prior to compiling the private
	part of a child unit, find on the scope stack the proper parent entity
	on which to link the use clause.
	(Note_Redundant_Use): Emit a warning when a redundant use clause is
	detected.
	(Analyze_Object_Renaming): An attribute reference is not a legal object
	if it is not a function call.
