title: How to get rid of g++ hash_map deprecation warning?
body: <p>When I compile a c++ application I'm writing that makes use of hash_map, I get this warning on g++ 4.3.2:</p>
  
  <p>You are using the deprecated header . To eliminate this warning, use an ANSI-standard header file or use hte -Wno-deprecated compiler flag.</p>
  
  <pre><code>9&gt; #include &lt;ext/hash_map&gt;
  </code></pre>
  
  <p>What include replaces this?  I've searched for a while on google, and can't find anything except for people having similar problems, but no solution.</p>
