If you generated such a wrapper and distributed it under the GPL, you're right back where you belong - even if it's your source originally. Once the user has that GPL'd dll, you have certain obligations to them that include giving them the source to the rest of the program. However, if you're building such a chain of dlls just to subvert the GPL, it won't work. Cygwin is still part of your program, and you still have to provide the sources to everything. -- Want to unsubscribe from this list?
