My point was that msys is just a fork of Cygwin.  If you incorporate it
into the project the you need to ship the DLL and you need to adhere to
the GPL, i.e., you need to provide the source code for any binary that
you ship, including msys.dll (or whatever it's called).

I don't want to start a typical Cygwin mailing list discussion here but,
as far as compatibility is concerned, with a couple of unimportant
exceptions, the Cygwin DLL maintains backwards compatibility.  Also,
Cygwin 1.7.x now allows coexistence of multiple versions of Cygwin.
