title: Enable a single warning in Visual Studio
body: <p>Is there a compiler switch to enable a single warning in Visual Studio?</p>
  
  <p>The reason I ask is I want to enable warning C4265 which is off by default. My searching has only turned up ways to turn warnings off.</p>
  
  <p>Even Microsoft pages called <a href="http://msdn.microsoft.com/en-us/library/edzzzth4.aspx" rel="noreferrer">How to: Enable or Disable Compiler Warnings</a> still only mention disabling.</p>
