--- Comment #15 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Confirming, as we might be able to support some subset of C++20 concurrency
primitives for the Win32 model. As
https://github.com/luncliff/latch/blob/master/latch_windows.cpp shows all
that's needed are atomic decrements and WaitOnAddress/WakeByAddressAll.
If our std::__atomic_wait_address and __atomic_impl::notify_all used those, we
could provide std::latch, and maybe others.
