non-GPL code in WinSCP

Hello,

I've cheked out HEAD revision form the CVS repository and found this

I think it is not possible link non GPL code with a GPL project. Would you please clarify this?

Isn't it vice versa?

It's both. GPLed apps can not link to closed source DLLs and vice versa (there is an exception for linking to files that are part of an operating system). The only instance you can link to closed DLLs is if you relicense the code (getting permission from all contributors).

No closed code can be hosted on Source Forge except for smaller runtime DLLs that normally ship with the operating system (Visual C++ runtimes are ok... .NET and Java aren't, for instance).

OK, thanks. I'll see what I can do about it.

Feel free to use my components.
