title: Build boost with msvc 14.1 ( VS2017 RC)
body: <p>I am trying to build boost 1.63 with the lastest msvc 14.1 and VS2017 RC.
  So I did everything I do normally, I opened the Development Cmd and then I run the bootstrap.bat and run the command</p>
  
  <pre><code>b2 -link=static -threading=multi
  </code></pre>
  
  <p>For some reason I got those errors :</p>
