title: intrin.h mingw error : No such file or directory
body: <p>I know that <code>#include&lt;intrin.h&gt;"</code> is windows specific (and runs in MSVS) but generates an error when I try to compile using MINGW: <code>fatal error: intrin.h: No such file or directory</code>
  How do I address this issue and get it to compile in MINGW?</p>
  
  <p>FYI, this is what I have in my .cpp where it is complaining and pointing to:</p>
  
  <pre><code>...
  #elif defined(WIN32)
      #include &lt;intrin.h&gt;
  ...
  </code></pre>
