Yes, I thought about that too.  Or actually, to have the script
executed before the specific package is deleted.

I'm afraid that to solve this problem entirely, we would need
preremove *and* postremove; and maybe something like Debian's purge.

But as long as setup.exe does it's own package management, this is
probably overkill; and I'd rather make a big improvement with a simple
patch, than try to go all the way.

The problem I wanted to solve (most) was for a package not to leave
anything behind after uninstall.  That's why I would vote for
postremove rather than preremove, and have it act like purge.  Maybe
it would be acceptable for a package like ssh not to purge the host
keys, but to delegate those things to /etc/postremove/cygwin.sh

Ok, my patch has something like /etc/postremove/package.{sh ? sh : bat}
that would be ok then?

Jan.
