Free- and OpenBSD have it too.  For Solaris I've found a feature request
only.  Dunno about MacOS/Darwin.  Other un*xes which are important these
days?

I'd *really* hate it to have the same system call with different
argument ordering on different systems though.  Especially when swapping
two integer values, so gcc wouldn't error out on wrong usage.
