working snapshot

[DJ Delorie]

I did some hacking in the winsup sources to work around the gcc bug
that hasn't quite gotten fixed yet (they're working on it) and I've
manually produced a snapshot that actually runs.  It's labelled
"1999-Apr-30" so it will get overwritten tonight when the regular
snapshot cron runs, but if you have a pressing need to play with a
recent snapshot, there's one there that works now.
