What about a few POSIX-violating fringe operating systems (Windows and DJGPP come to mind)? :) For Windows we can write our own stat function in cygwin, but for DJGPP I think we're in a bad situation...
The attribute tests fix it in practice, but since this is not an optimization, perhaps gnulib's SAME_INODE module should provide an indicator of the reliability of the macro.
