Some compilers support r-value reference while not providing implicitly-defined move ctor/assign (e.g. VC10), is there a way to detect this defect?

Macro like BOOST_NO_IMPLICITLY_MOVABLE would be helpful.

Is "defined(BOOST_NO_CXX11_RVALUE_REFERENCES) || defined(BOOST_NO_CXX11_DELETED_FUNCTIONS)" good enough?

Thanks,
