That's probably the easiest and sanest approach.  If it makes you feel
better, SCSH itself also runs only on Unix-like systems, and relies on
cygwin to support Windows.

Thanks for explaining how this works.  Hopefully someone will attempt
this at some point in time, but for now we'll have to make do with
pointing people at cygwin.
