title: How to use SGI STL hash_map?
body: <p>I am trying to use the SGI STL implementation I have downloaded from their site. I want to use a hashmap, because I have to store around 5.000.000 records, but it should be good: I need to be able to access it very quickly. I've tried <code>stedext::hash_map</code>, but it was very slow because I couldn't set the initial size. By the way, is it possible to do that? 
  If I add the additional path to my MS Visual Studio, I can't even compile the example from the SGI site. I get an error message: </p>
  
  <pre><code>error C2061: syntax error : identifier 'T'.
  </code></pre>
  
  <p>Has anyone else faced such problems?</p>
