title: mingw update compile with -std=c++11
body: <p>I've noticed that with a new mingw version, I can't compile anymore with -std=c++11. It will outputs a bunch of errors, which can be "fixed" by using -std=gnu++11 ( <a href="https://stackoverflow.com/questions/38436542/mingw-cxxtest-bizarre-errors">MinGW / CxxTest bizarre errors</a> ).</p>
  
  <p>This quick hack works, but it doesn't fix the actual problem. How do I compile with c++11 flag? A lot of projects uses c++11, I don't want to change every makefiles to make it work, mingw should handle this ( in fact, It worked on my last version, before updating ).</p>
  
  <p>Example code ( g++ Main.cpp -std=c++11 ):</p>
  
  <pre><code>#include &lt;iostream&gt;
  int main()
  {
      std::cout &lt;&lt; "ok...." &lt;&lt; std::endl;
      return 0;
  }
  </code></pre>
