I don't think so, unless they come with two different `libc`s, in which case those applications using the newer `libc` might still work and those with the old `libc` won't, but even so users of such a system will presumably know that those programs using the old `libc` need to be run in a specialized environment with a bogus time or something like that. The argument is that whatever happens to Emacs will also happen to ll other programs using that same `libc`, so Emacs doesn't really need to say anything. Stefan
