(An implementation could, instead of >actually removing a file, simply change the name.) And POSIX is not ANSI and vice versa. There is no "standard C". Add to this that POSIX is not unix, just a subset (e.g. VMS also includes POSIX, which is really not unix, fortunately - for VMS). That makes it much more difficult for beginners.
