A feature, obviously.  But I don't see the need for dependency-name in
the first place.  I think it won't work in practice -- actual
dependencies are too messy and too informal.

If you're going to have new names only, you should put the priority
as the first arg, since it's shorter.

As long as we're being more general, perhaps the general facility should
be something like this:

AC_ATEXIT(priority, action)

That will let you do whatever you like at the end, including futz with
the exit status I suppose.  Then we wouldn't need AC_MSG_END.

Also -- a small point -- priorities should all be positive.  (This
allows for future extension.)
