Subject: License question about Cygwin


> As the Cygwin.dll is licensed under GPL, any "Program" that links to it
must
> be released under GPL as well.
>
> My question is, what if the "Program" also links to proprietary .dlls that
> are authored by someone else. That source can not be published (I don't
even
> have access to it). Furthermore these .dlls are not freely available.
>
> Does that mean that even if I publish all of my source code, I would still
> be violating the GPL because I couldn't publish the source code to the
> proprietary libraries.
>
> Thanks for any help.
