Have 10.1/Darwin, vacpp/AIX and gcc 4.3.4/FreeBSD rvalue references when running on C++098 mode?
I don't undesrtand how this test can work with your move semantics emulation?

boost::thread make_thread_return_local(boost::thread::id* the_id)
{
    boost::thread t(do_nothing,the_id);
    return t;
}
