This appears to work and makes more conceptual sense to me as well 
(sorry if the formatting gets mangled, but you get the idea):

replace:

#define BOOST_CLASS_EXPORT_GUID(T, K) 
             \
namespace 
             \
{ 
             \
     ::boost::archive::detail::guid_initializer< T > const & 
              \
         BOOST_PP_CAT(boost_serialization_guid_initializer_, __LINE__) 
                     \
         = ::boost::serialization::singleton< 
              \
             ::boost::archive::detail::guid_initializer< T > 
              \
           >::get_mutable_instance().export_guid(K); 
              \
}

with:

#define BOOST_CLASS_EXPORT_GUID(T, K) 
             \
namespace 
             \
{ 
             \
     ::boost::archive::detail::guid_initializer< T > const & 
              \
         BOOST_PP_CAT(boost_serialization_guid_initializer_, T) 
              \
         = ::boost::serialization::singleton< 
              \
             ::boost::archive::detail::guid_initializer< T > 
              \
           >::get_mutable_instance().export_guid(K); 
              \
}
