Comment:

 OK _ looked at this more carefully.

 There is more going on here than meets the eye.

 test_private_base.cpp demonstrates that one can serialize a private base
 class with no problem.

 test_private_base.cpp demonstrates the problem which occurs when one tries
 to serialized through a pointer to a private base class.  The program
 fails to compile at line 90.  Basically one cannot do this in C++.  I've
 searched in vain for a way to do this but haven't found any.  The
 BOOST_CLASS_EXPORT uses the same functionality to implement this facility
 so it has the same problem.

 Bottom line - serializatiion of private/protected base classes is fine -
 but one cannot serialize such classes through a base class pointer.
