Just to give an example in real life I stumbled over, which is qute
popular around here: Cygwin.

It is distributed under the GPL, but Red Hat sells you the Cygwin-DLL
under a different license if you want to. To quote
http://www.redhat.com/software/tools/cygwin/buycontract.html:
  
  The Cygwin libraries are covered by the GPL. The GPL requires the
  source to any application built with the Cygwin libraries must be
  distributed with the application. Red Hat sells a Cygwin Buy-Out
  License for customers who are unable to provide their application in
  open source code form.
