Discussion:

I'm looking at 31 [atomics] and can't really make sense of a couple of things.

Firstly, there appears to be a typo in the `<cstdatomic>` synopsis:

> The `atomic_exchange` overload taking an `atomic_address` is missing the second parameter:

> >     void* atomic_exchange(volatile atomic_address*);

> should be

> >     void* atomic_exchange(volatile atomic_address*, void*);

> Note, that this is not covered by 880 "Missing atomic exchange parameter", which only talks about the `atomic_bool`.

Proposed resolution:

Change the synopsis in 31 [atomics]/2:

>     void* atomic_exchange(volatile atomic_address*, void*);
