It's not an OS thing, it's a toolchain thing.  getaddrinfo_a() is implemented
using standard C and POSIX threads, it doesn't need OS-specific support.

Linux has it because Linux uses libc whether you're compiling with gcc
or clang.  Any of those other platforms will have it *if* they have
(gcc || clang) && glibc.

There is at least one other implementation out there, in a GPL-licensed
plackage called "adns".
