+
+	* TAO_IDL/be/be_interface.h: Added some helper methods to generate
+	additional code in the form of larger operation tables, and
+	skeletons. This situation arises when we have single/multiple
+	inheritance of interfaces.
+
+	* TAO_IDL/be_include/be.h: Included ace/Containers.h for the
+	ACE_Unbounded_Queue that uses the breadth-first strategy used in
+	be_interface.cpp
+
+	* TAO_IDL/be/{be_interface,be_operation,be_attribute}.cpp: Added code
+	to generate a new "virtual void dispatch" method on the skeleton
+	classes. The dispatch method enables us to access the most derived
+	type when invoking the skeleton for a method. The skeletons
+	instead of taking a CORBA::Object_ptr, now take void*. The
+	skeletons themselves cast this void* to the appropriate POA_*
+	type.
+
+	In addition to the above, for the case of inheritance of
+	interfaces, it is not appropriate to pass a pointer to the most
+	derived class as a void* to the skeleton of a base class and cast
+	that to the POA_* of the base class. So we generate inlined code
+	for skeletons of methods in the most derived class even if those
+	methods were defined in the base classes. These inlined skeletons
+	simply cast the object pointer to the right type and invoke the
+	corresponding skeleton of the base class method.
+
+	be_interface.cpp defines a template method to traverse the entire
+	inheritance graph. This traversal is done using a breadth-first
+	traversal. This traverse method takes a pointer to one of the
+	static helper methods defined on class be_interface. Each helper
+	achieves a different purpose such as generation of extended
+	operation tables, providing comparisons of repositoryIDs of base
+	classes in the _is_a methods of derived classes.
+
+	The client-side class now defines a virtual CORBA::Boolean _is_a
+	method. This uses local knowledge of repository ids thereby
+	preventing the expensive remote call in most cases. All changes
+	made in be_interface.cpp
+
+	* TAO/tao/corbacom.h: Changed the signature of TAO_Skeleton so that
+	it uses void*obj and a void *context.
+
+	* TAO/tao/object.h: Added a virtual dispatch method as explained
+	above.
+
+	* TAO/tao/orb.h: Redefinition of TAO_Skeleton removed.
+
+	* TAO/tao/poa.cpp: Changed the demultiplexing code to reflect the
+	change made with the dispatch method. The poa on finding the right
+	object corresponding to the key, now invokes the dispatch method
+	on that object which by dynamic binding invokes the dispatch
+	method of the POA_* class.
