Jonathan Wakely 4e2d1a1c36 libstdc++: Use 32-bit platform wait type for OpenBSD and DragonFly [PR120527] 
This defines __platform_wait_t as unsigned int for OpenBSD and
DragonFly. This means that std::semaphore will use unsigned int by
default, and so will benefit from more efficient wait/notify ops if we
start to use the OpenBSD futex(2) syscall or the DragonFly umtx(2)
syscalls. We don't currently use them, but if we start to in future, it
would be an ABI break to change __platform_wait_t later.

libstdc++-v3/ChangeLog:

	PR libstdc++/120527
	* include/bits/atomic_wait.h [__OpenBSD__ || __DragonFly]: Use
	unsigned int for __platform_wait_t.
