title: Cannot use boost::threads in Visual Studio 2012
body: <p>I get the following error using boost::threads in visual studio 2012 (CTP Nov 2012). I'm using boost 1.53.</p>
  
  <pre><code>1&gt;boost/config/requires_threads.hpp(29): fatal error C1189: #error :  "Threading support unavaliable: it has been explicitly disabled with BOOST_DISABLE_THREADS"
  </code></pre>
  
  <p>I found advice on the interwebs, to use the multi-threaded c runtime. (I am, doesn't work.) And then there is a vast silence on what to do about this problem. Is boost dropping support for visual studio??</p>
