To summarize the situation for different versions, we have:

Emacs 23.0.0  (without multi-tty, with unicode-2) -> OK
Emacs 23.0.50 (with multi-tty, without unicode-2) -> NG
Emacs 23.0.60 (with multi-tty, with unicode-2)    -> NG

So, multi-tty seems to be suspicious.  Maybe multi-tty has never been
tested with any CANNOT_DUMP platforms?

Also, loadup.el was changed by multi-tty so as to preload
window-system-specific initialization files such as term/x-win.el for
some reason.  If this change was by necessity (i.e., to avoid some
problem that happens when they are not preloaded), not for efficiency,
then this might affect CANNOT_DUMP platforms.
