Thanks for this patch, it looks pretty useful.  There are just two
things missing.  First, could you please create a matching ChangeLog
entry?  Second, worse, I don't see your name on the list of people
having a copyright assignment in place, which is definitely necessary
for a patch of this size.  We need a written copyright assignment from
you once, after that, you can create as many patches as you like.
Please see http://cygwin.com/contrib.html for the gory details about
the copyright assignment form and how to send it to Red Hat.


Thanks,
Corinna
