With a little fiddling, I think that this might be made to work.

#define BOOST_CLASS_EXPORT_GUID(T, K)                                \
namespace                                                            \
{                                                                    \
    template< typename U >                                           \
    class init_guid;                                                 \
    template<>                                                       \
    class init_guid<T>                                               \
    {                                                                \
        static ::boost::archive::detail::guid_initializer<T> const & \
        guid_initializer_;                                           \
    };                                                               \
    ::boost::archive::detail::guid_initializer<T> const &            \
        init_guid<T>::guid_initializer_ =                            \
            ::boost::serialization::singleton<                       \
                ::boost::archive::detail::guid_initializer<T>        \
            >::get_mutable_instance().export_guid(K);                \
}
