Hmm.  Good question.  We certainly are not going to waste bandwidth
discussing MSYS here.  The sources for setup are available (of course).
If you have questions, consult them.

We're not going to help design a new installer for a Cygwin fork.  Talk
to the vast and canny team of MSYS developers if that is required.
