// This is the implementation of Python atomic operations for MSVC if the
// compiler does not support C11 or C++11 atomics.
//
// MSVC intrinsics are defined on char, short, long, __int64, and pointer
// types. Note that long and int are both 32-bits even on 64-bit Windows,
// so operations on int are cast to long.
//
// The volatile keyword has additional memory ordering semantics on MSVC. On
// x86 and x86-64, volatile accesses have acquire-release semantics. On ARM64,
// volatile accesses behave like C11's memory_order_relaxed.
