In both cases the temporary should get RVO'd (i.e. the copy should be elided) on all modern compilers. If you can find a modern compiler where Boost.Move does not RVO, then its design needs to be fixed.
Does Boost.Move support moveable-but-not-copyable types? Could this cause compile errors for such types when compiling with optimization turned off?
Yes in case of constructors but not with assigments:
clone_ptr<MyClass> p;
for(){ p = return_rvalue(); }
Although I guess that this missed optimization might not be so important. The same could be applied to containers
//With old approach, copied instead vector.push_back(return_rvalue());
