Yes, I guess that would work just as well nowadays.

I suppose I was reflexively worried about older systems that had
"#define chown __something...." in their unistd.h, with no
implementation of chown.  These had something to do with changing
uid_t width or with converting from non-prototypes to prototypes or
something like that (sorry, I don't remember the details).  You can
get a glimpse of these old practices (though it's not exactly what I
remember) in:
