Deleting Emacs support for obsolete platforms

[Richard Stallman <rms@gnu.org>]

In Emacs 23 we are thinking of deleting Emacs support for the systems
and computers listed below, because we think they are obsolete and
not useful.

If you know of a reason to keep support for any of those platforms,
please send an explanation to emacs-obsolete-poll@gnu.org.  We will
try to keep the support for platforms that people actually want.
