window configurations no longer (since 21.5) include windows ! ?

The following code behaves differently in 21.4.21 and 21.5.28:
(let ((w (selected-window))
(c (current-window-configuration)))
(split-window)
(view-buffer-other-window "foo")
(delete-window w)
(set-window-configuration c)
(window-live-p w))
Paste the above into *scratch* and execute it -- value is t in 21.4.21
and nil in 21.5.28. Basically, window identity is not preserved in
configurations, or, therefore, by save-window-excursion. This
causes no end of trouble for ecb.
I'm pretty sure this is unintentional. Mike Sperber -- mike at xemacs
dot org -- did the work, if you don't see a reply from him shortly you
may want to ping him. He's definitely active at the moment.
