Please review: https://cygwin.com/licensing.html

Cygwin's license contains a linking exception for software licensed 
under terms which satisfy the Open Source Definition 
<https://opensource.org/osd>.  For our purposes, a good reference is 
<https://fedoraproject.org/wiki/Licensing:Main>.

True, but it is Open Source and therefore would be acceptable.
