LGPL allows you to create commercial application linked against this library as long as you provide a way to replace LGPLed library (for example application links to library dynamically). In some cases it's still possible to use some GPLed libraries in commerce application, if application is not "derived work" in terms of GPL (for example you can use GPLed plugins as long as you distribute plugin apart from you application and you distribute plugin in open source under GPL). Additionally, there is a lot of difference "freeware" licenses and "public domain" code, not covered by any license. As for Cygwin: yes, according to GPL all derived work must be GPLed. Copyright question is not so simple as you may think, but it primary depends on the contracts between you and your employer. -- ~/ZARAZA Ибо факты есть факты, и изложены они лишь для того, чтобы их поняли и в них поверили.
