mknetrel is, AFAIK, only used by myself for producing net release packages.  Egor
Duda has obviously been experimenting with it (possibly for use in building gcc)
but he doesn't use it for package maintenance yet, AFAIK.

Yes, I have never run this under cygwin, actually.  It was intended as a
cross-compilation environment.  I'm surprised that it works on cygwin
with so few changes.

Yep.

You should be able to say "mknetrel cygwin" to have it build the latest version.
Again, I'm surprised that it would actually work with explicit versions.

"That's the way it works" (tm)
