// This is an overly complex test.  The purpose of this test is to
// demostrate and test the ability to serialize a hiarchy of class
// through a base class pointer even though those class might be
// implemente in different dlls and use different extended type info
// systems.
//
// polymorphic_ base is locally declared and defined.  It use the
// "no_rtti" extended type info system.

// polymorphic_derived1 is locally declared and defined.  It uses
// the default "type_id" extended type info system

// polymorphic_derived2 is declared in polymorphic_derived.hpp
// and defined in dll_polymorphic_derived2.  It uses the typeid
// system.
