	* sprint.adb (Write_Id): If the parent node is an expanded name, check
	that its entity_or_associated_node is an entity before writing it out.
	* exp_disp.adb (Make_Tags); if a type is declared in C++ and has no
	constructors, there is no need for a dispatch table pointer because the
	table is fully inherited from the C++ code.
