That sort of presupposes that someone is interested in walking people through
the debugging of the cygwin DLL. I know I'm not interested and I haven't
seen anyone else step in when people start asking debugging questions.
I guess the words in problems.html could be extended with a "You're basically
on your own"...
This is not a bad idea, especially since I thought of it myself long ago :-),
like I said, it just requires some time which I don't have right now.
