Yup, that's what I figured.  But this compiler doesn't have std::move().

test_thread_return_local.cpp(17): error: namespace "std" has no member  
"move"
     return std::move(t);
                 ^

Any other ideas on how to get these Darwin / Intel tests running  
Anthony?  Would the Boost.Move library currently under review work here?
