That's not totally correct i'm afraid.

Should be

#if (__cplusplus > 199711L) || (defined(_MSC_VER) && _MSC_VER >= 1800)

Now, ideally we should define CYCLES_USE_CPP11 in util_types.h in order to avoid this rather obscure condition happening allover the place, but the issue with this is util_types.h is not guaranteed to be included before other includes.

We could introduce util_compiler.h and such checks/defines into there and include this header before checking for C++11.

Or for now we might just not bother and copy-paste longer ifdef :)
