/**
* @fileoverview C11 Atomic Types
*
* We supoprt C++ and old C compilers. It's recommended you use macros
* like `_Atomic(int)` rather than `_Atomic int` or `atomic_int` since
* we only define a portability macro for the syntax `_Atomic(T)`.
*
* @see libc/integral/c.inc
* @see libc/bits/atomic.h
