I suspect that the move constructor is missing

   Dummy(BOOST_RV_REF(Dummy) other);

and this should be removed I guess

   Dummy& operator=(BOOST_RV_REF(Dummy) other);

The documentation covers all the versions up to version 4.0.0. But the 
default version is 2 as requested in this ML, as version 3 introduced 
some not desired breaking changes.
