  30         Because the TIB (thread information block) is not fully described in the
  31         MSDN, it might be possible that not all required TIB-parts are swapped. With
  32         compiler flag <code class="computeroutput"><span class="identifier">BOOST_USE_WINFIBERS</span></code>
  33         <code class="computeroutput"><span class="identifier">execution_context</span></code> uses internally
  34         the Windows Fiber API.
