title: Netbeans "__cplusplus" Defined Wrong
body: <p>In my Ubuntu Netbeans 7.3 installation, I have a C++ project with C++11 marked as the standard in the C++ Compiler Options. When I try to include <code>&lt;chrono&gt;</code> it does not seem to make the <code>std::chrono</code> namespace available. When I open up this file to see what's wrong, I see everything greyed out but his first section: </p>
  
  <pre><code>#ifndef _GLIBCXX_CHRONO
  #define _GLIBCXX_CHRONO 1
  
  #pragma GCC system_header
  
  #if __cplusplus &lt; 201103L
  # include &lt;bits/c++0x_warning.h&gt;
  #else
  </code></pre>
  
  <p>When I hover over the <code>__cplusplus</code> constant, to see how it was defined, it says it's defined as <code>199711L</code>. Why is this? I clearly set the project C++ Standard to C++11. </p>
