 boost::serialization will not compile code that serializes a class that
 has non-public base classes.  It complains about an inaccessible base --
 despite the friend definition for serialization::access.

 There is a workaround for private base classes, since those can be
 emulated by private member variables, but I can't think of any way to work
 around the protected inheritance problem.

 I am using g++ 4.3.3
 Running on Ubuntu 9.04

 I have attached two source files that cause the problem, one minimal and
 one slightly less minimal (with some preprocessor macros I used to trace
 down the problem).

 I have also included the compiler output for the minimal code and the
 Makefile I use to build them.
