Yes, in the sense that all the APIs introduced by multi-tty do work in
the MS-DOS port if they make sense on DOS.

For example, make-frame-on-tty does make sense on MS-DOS when its
first arg is "/dev/tty" or "CON", so I didn't want it to fail just
because it assumed that on a tty, the value of window-system _must_ be
nil.
