Actually, since I'm usually the one who does the FreeBSD ones anyway, here you go:
https://github.com/dlang/dmd/pull/16359 The declarations compile, and they should match the ones in C, since I copied them over and then tweaked them, but I haven't actually tested them. All that being said, even if they're merged immediately, they won't be available as part of druntime until dmd 2.109.0 is released (and 2.108.0 was released less than a week ago), so you'll probably need to copy them into your own install or use the development version of dmd to get the updated bindings if you want to use them now. - Jonathan M Davis
