Do we?  Do you know (of) someone using a recentish Emacs on Windows 9X?

Yes, he described the extra efforts that we should spend to try and
provide support for those hypothetical Windows 9X users out there.
I think that is very likely to be a waste, so I think we should first do
the easy thing and *if/when* someone comes complaining that it doesn't
work on Windows 9X then we can revisit this decision.
