Comment (by viboes):

 I don't understand the warning


 {{{
 1>c:\program files\c++\boost\boost\thread\future.hpp(1624): warning C4702:
 unreachable code
 }}}

 given the following code

 {{{
         BOOST_THREAD_FUTURE<R> get_future()
         {
             if(!task)
             {
                 boost::throw_exception(task_moved());
             }
             else if(!future_obtained)
             {
                 future_obtained=true;
                 return BOOST_THREAD_FUTURE<R>(task);
             }
             else
             {
                 boost::throw_exception(future_already_retrieved());
             }
             return BOOST_THREAD_FUTURE<R>();

         }
 }}}

 Could you point me where is the problem?
