没有 C++11 支持的原子？

Question

For backwards compatibility reasons, we need to support versions of C++ prior to C++11, so we cannot use std::atomic<...> . However, we still need atomics.

Is there an alternative to std::atomic<...> that's possible in previous versions of C++?

Preferably without including any new dependencies, but I realize this might be impossible.

EDIT: we need this specifically for Unix and Xbox360. We have considered Boost but don't want such a large depeundency for one platform that we will upgrade to C++11 in a few years.

GCC 具有对原子http://gcc.gnu.org/onlinedocs/gcc-4.6.2/gcc/Atomic-Builtins.html 的内置支持
