What an arrogant statement. I was trying to distill this down to simple, clear sentences. There is a lot more that can be said about this but, if you really don't understand if you are affected then you need to consult both technical and legal help. >It would be better to say something like this: If you distribute a >program linked to the cygwin DLL without making that program available >under the GPL (or an equivalent allowable license) you are in violation >of the license under which you received the cygwin DLL in the first >place. > >It is possible, but unlikely, that a court could order a remedy that >would force you to distribute your program under the GPL.

That is entirely debatable and you have no basis for making such an authoritative statement. >Fears that programs might somehow be automatically forced under the GPL >may help propagate the (false) perception that the GPL is "viral". When you use the cygwin DLL in your program and distribute it, you are implicitly agreeing to the license terms of the cygwin DLL. That means that you must adhere to the GPL, ergo your program is GPLed. It is Red Hat's intent that the only acceptable use of the cygwin DLL should be in accordance with the GPL as described on the cygwin licensing page. If you are distributing your program without checking on the licensing of the software that it uses, then you get what you deserve. If you want to debate the fine points of the law, then either contact Red Hat directly or find another mailing list. Until then, my poorly worded statements will have to serve as the definitive answer for this topic. -- Christopher Faylor spammer? -> [EMAIL PROTECTED] Cygwin Co-Project Leader [EMAIL PROTECTED] TimeSys, Inc. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
