I don't know about getting rid of the unnamed namespace but essentially we just need a unique name per type in a translation unit.. so how about:
#define BOOST_CLASS_EXPORT_GUID(T, K) \ namespace \ { \ template< typename U > \ class init_guid \ { \ static ::boost::archive::detail::guid_initializer<U> const & \ guid_initializer_; \ }; \ template<> ::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); \ }
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); \ }

That appears to work for me! Of course I've only tested it in my particular use-case. Can this fix be committed to trunk so that it's tested more thoroughly, and maybe included in a future release?
