Are you sure your compiling with Boost 1.53?
start_thread is defined in boost/thread/detail/thread.h lines 178-184 as

         void start_thread()
         {
           if (!start_thread_noexcept())
           {
             boost::throw_exception(thread_resource_error());
           }
         }

Please could you check this file and the contexts of this linenes

Best,
