title: Using Qt Creator C++ 11, nullptr is keyworded?
body: <p>I'm using C++11 using Qt Creator.</p>
  
  <pre><code>"warning: identifier 'nullptr' is a keyword in C++11 [-Wc++0x-compat]"
  "error: 'nullptr' was not declared in this scope"
  </code></pre>
  
  <p>This is on code that works elsewhere, the relevant part being:</p>
  
  <pre><code>... = nullptr;
  </code></pre>
  
  <p>What might be the problem?</p>
  
  <p>Is this not already a keyword, isn't it's scope global?</p>
