Re: License question about Cygwin


RedHat has granted a special exception that allows any open source to link
to Cygwin.dll.

As the legal copyright holder, RedHat may grant any sort of exception to the
GPL they want, and are not bound to the GPL.   (This only applies to
Cygwin.dll and other components that RedHat can claim ownership for.)
