Could I at least define by the default (even for BOOST_THREAD_VERSION 2) BOOST_THREAD_USES_MOVE for Boost 1.57?

I think that would be good. We have to compile with BOOST_THREAD_USES_MOVE as some of our code doesn't work without it on some of our platforms. We're using BOOST_THREAD_VERSION 4 now, but BOOST_THREAD_VERSION 2 + BOOST_THREAD_USES_MOVE would also work.
