Comment (by mark.r.buda@…):

 I took BOOST_CLASS_EXPORT_GUID and split it into two macros, removing the
 namespace bits:

 {{{#!cpp
 #define BOOST_CLASS_EXPORT_PROTECTED_1(T)                              \
   static ::boost::archive::detail::guid_initializer< T > const         \
   & guid_initializer;                                                  \

 #define BOOST_CLASS_EXPORT_PROTECTED_2(W, T, K)                        \
   ::boost::archive::detail::guid_initializer< W::T > const &           \
   W::guid_initializer =                                                \
            ::boost::serialization::singleton<                          \
                ::boost::archive::detail::guid_initializer< W::T >      \
     >::get_mutable_instance().export_guid(K)                           \
 /**/

 class foo {
   protected:
     class bar {
     // ...
     };
     BOOST_CLASS_EXPORT_PROTECTED_1(foo::bar)
 };

 BOOST_CLASS_EXPORT_PROTECTED_2(foo, bar, "foo::bar")
 }}}
