Actually, better would be to make the old syntax simply cause a useful
warning message to be printed, _forcing_ people to update their
MAKEDEV scripts (or to use the right syntax, if they really are trying
to use the new numbers).

After a release, the special 'new number' flag operation could be made
the default, and left alone for compatibility.

After another release, it could be removed entirely.


I'll repeat again: i'd rather cause -current users slight
inconvenience -- upgrades should take care of /dev -- than be stuck
forever with an ugly and more expensive to handle dev_t format.
