title: Does Unreal Engine 4 toolset support C++11 or C++14 on OS X / Clang?
body: <p>I have some interest on UE4. Currently, I am developing a mobile game, and have a pretty large existing codebase written in C++11/14 with Clang. </p>
  
  <p>AFAIK, UE4 is using a custom compiler (preprocessor? whatever), and that means C++ compatibility may differ on their own tools. How is the support for C++11/14 on UE4?</p>
