Current cygwin fails to delete or create /dev, since it's always available as a virtual directory. rm fails because it's not empty and mkdir fails because it already exists. We could shell out to cmd.exe, but let's just continue to assume that /dev exists in the installer base. Also saves a useless mkdir call.
