Also, why are endpwent, getpwent, setpwent, getpwnam_r, and getpwuid_r restricted to openbsd here? Only getpwuid_shadow and getpwnam_shadow are openbsd-specific, the rest are in POSIX

I'm guessing whoever added them only checked them for OpenBSD? std.c is full of little quirks like this.

But they obviously went through the trouble of looking at the layout of struct passwd for many unixes, for the function itself you only need to make sure it's in POSIX right?

Right. It was probably a sloppy contribution and then never properly reexamined (by me) during a non-functional code transformation.

i rebased because it looked like x86_64-linux-debug-llvm and x86_64-linux-release were stuck, can you approve CI again?
