Context Free Forums and Gallery

I am thinking of using some C++11 features, but I don't want to leave anyone behind. What compiler are you using? I want to use unique_ptr, shared_ptr, and STL containers with move semantics. Range-based for and auto type would be nice if nobody is using gcc 4.4 or clang 2.9. Visual studio 2010 users will be out luck. The free visual studio 2012 express is all I use on Windows.

I have clang/gcc/xcode, so all is fine with me.
But normally I just download ContextFree.app.

gcc version 4.7.2 variants on Ubuntu and Archlinux (64bit)
