   It says that the class declaration may be placed in a separate header,
but that doesn't mean BOOST_CLASS_EXPORT_GUID must be placed
to that header too :)
   When you create a separate header for the class, usually you also create
a separate .cpp for it. Place BOOST_CLASS_EXPORT there and everything
will work fine.
