Right, thanks for the clarification, Dave. I forgot that chere needed to
be explicitly invoked to add the association (and thus explicitly invoked
to remove it as well). This also applies to other packages that need to
be explicitly configured (e.g., sshd, cron, etc).
In any case, the advice still applies -- any package that was installed
using Cygwin setup will need to be uninstalled using Cygwin setup to give
the preremove scripts a chance to run. Technically, the preremove scripts
should undo whatever the postinstall scripts did (if they don't, it's a
packaging bug).
