Pass a preprocessor define to identify us.

Needed so that <stdatomic.h> can identify when a <atomic> header is
available. We need to do this because including <atomic> after
<stdatomic.h> causes compilation to fail, and the cleanest way out of
that situation is to make <stdatomic.h> include <atomic> when it is
using in a C++ context.
