This is largely a non-issue.

The GPL only applies if you distribute the source code and/or the 
resulting build that links to Cygwin.

The use case I am trying to improve is providing a development 
environment for people who deploy to Linux servers. Cygwin is not part 
of the resulting software.

See my email to Jose Valim for more details.
