title: to_string(42) more than one instance matches the argument
body: <p>Exacly as in the subject I use VS2010:</p>
  
  <p>I have:</p>
  
  <p><code>std::string s = std::to_string(42);</code></p>
  
  <p>and the error</p>
  
  <pre><code>Error   4   error C2668: 'std::to_string' : ambiguous call to overloaded function
  </code></pre>
  
  <p>how to repair it?</p>
