        * exp_attr.adb: 
        (Expand_Access_To_Protected_Op): If the context indicates that an access
        to a local operation may be transfered outside of the object, create an
        access to the wrapper operation that must be used in an external call.
	(Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
	target, pass the Valid attribute applied to a floating-point prefix on
	to the back end without expansion.
	(Storage_Size): Use the new run-time function Storage_Size to retrieve
	the allocated storage when it is specified by a per-object expression.
	(Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
	Nothing to do here, the attribute has been rewritten during semantic
	analysis.
	(Expand_Attribute_Reference): Handle expansion of the new Priority
	attribute
	(Find_Fat_Info): Handle case of universal real
	(Expand_Access_To_Protected_Op): Fix use of access to protected
	subprogram from inside the body of a protected entry.
	(Expand_Access_To_Protected_Op): Common procedure for the expansion of
	'Access and 'Unrestricted_Access, to transform the attribute reference
	into a fat pointer.
	(Is_Constrained_Aliased_View): New predicate to help determine whether a
	subcomponent's enclosing variable is aliased with a constrained subtype.
	(Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
	test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
	an aliased prefix must be known to be constrained in order to use True
	for the attribute value, and now it's possible for some aliased views
	to be unconstrained.
