A patch cygwin1.dll is available at > Thanks Alexander, that looks good. Unfortunately I can't apply that patch if you haven't signed a copyright assignment form. Your patch isn't a `trivial' patch anymore which would allow us to include it w/o the assignment. Please have a look on http://cygwin.com/contrib.html. If you could send that assignment form via snail mail to Red Hat ASAP (the address is given on the form), I will be really glad to apply your patch.
