That's right.  As the license holder for cygwin we reserve the right to
distribute the code under a different licensing agreement.

We do allow our customers to distribute code linked with the DLL under
other terms than the GPL -- for a fee.

I don't believe that Suhaib is referring to our own products however, and
I don't believe that he is referring to a commercial customer of Cygnus.
