The POSIX recommendation was therefore that GNU should change its behavior to act like HP-UX, and consider identical timestamps as out-of-date, because the standard will be fixed to allow HP-UX behavior.
A change like this may result in some builds which never complete (or take much longer) because the timestamp rules require that something be rebuilt (tail chasing). This is particularly a problem for recursive builds which may enter the same directories multiple times.
