Hi Danny,

I will try to answer both mails in one.

So I will do so, though I havenīt done yet.

Iīve noticed that now, too.

This is not much of a problem. I provide a windows-installer, put the 
dll there and leave system-dlls alone.

I interpret this as this: I will have to provide the sourcecode of 
libstdc++ if I change it. Using this lib in proprietary software is allowed:

Fine.

Zum Donnerwetter!

I would sure like to test gcc 4.2.0 as I see that this issue will 
probably be hard to fix with 3.4.5. So I could just have a look with 
4.2.0 and see if the issue is gone.

Thanks for your help. I hope that my problems will in the end help to 
improve gcc/mingw.

Regards,

Andreas
