Andrey, the provided patch goes too far for what I was expecting. You have made a lot of changes, C++11 interface has not been preserved, and I'm not sure the algorithm is the same.
The algorithm is different for sure. What exactly do you mean by C++11 interface? Does C++11 have call_once? The only C++11 thing I saw was the once_flag definition which gave no apparent benefits.
C++11 defines the following interface. There is no STD_ONCE_INIT initializer. struct once_flag { constexpr once_flag() noexcept; once_flag(const once_flag&) = delete; once_flag& operator=(const once_flag&) = delete; }; template<class Callable, class ...Args> void call_once(once_flag& flag, Callable func, Args&&... args); Could this once_flag be implemented using the trick you used to mask the atomic dependency on the header file?
