You are right! And I apologize for that.
But it is beyond my influence because our mailsverver add this crop.
I have talked to the admins and hope that they will fix it.

I guess your guess is wrong!

Because with a dll
         without the patch based on the issue eclipse/perl works
        with the patch applied don't

So whats so hard to understand ??

First of all if you deciede not to use Eclipse because of religious believes it is ok!

Second I know it is hard to fix things if the reports are unspecific. But I'm really
        not able to give more precise reports. Corinna send different dlls which
        I tested        according to her advice and give feedback. I suggest to do the
        same in your case.

Third If the same Programm works well with one Version of  Cygwin and not with
        a newer Version of Cygwin it is not the fault of the Programm

Forth if the Programm did not work with a patch applied dll but without the patch
         the reason has to do with the patch. Maybe not the patch itself but at least
        with its side effects.

At least if this problem is not fixed we will just use the old cywin version which runs
without any problems and not stop using Eclipse/perl.

Have fun
