title: How do I stop an IntelliSense PCH Warning?
body: <p>A few of my header files have no includes, so I receive this message in Visual Studio 2010:</p>
  
  <pre><code>IntelliSense: PCH warning: cannot find a suitable header stop location.  An intellisense PCH file was not generated.
  </code></pre>
  
  <p>If I add a single header, for instance:</p>
  
  <pre><code>#include &lt;iostream&gt;
  </code></pre>
  
  <p>It disappears. How can I stop this error from showing without adding (potentially unused) include></p>
