By this reasoning, I would have to evaluate kernel implementations forever, for all the supported systems, just in case someone decides to change the semantics of a system call and while still claiming that link(2) is POSIX conformant. Likewise, I would have to evaluate ANSI C environments and ensure that some implementation does not introduce a change. That is obviously not practical. Wietse
