Corinna +1'ed my suggestion that it was time to remove cygwin 1.5 support so I'm wondering if anyone has any objections to removing 1.5 from cygwin.com.
I was going to suggest this a few months ago and mention that the Cygwin Time Machine was an alternative but it looks like that service is no longer available. So, as an alternative, we could advertise that the directory is going away on the main web page for a month before nuking it. cgf
