title: Get 32-bit hash value from boost::hash
body: <p>I am using <code>boost::hash</code> to get hash value for a string.
  But it is giving different hash values for same string on Windows 32-bit and Debian 64-bit systems.</p>
  
  <p>So how can I get same hash value (32-bit or 64-bit) using <code>boost::hash</code> irrespective of platform?</p>
