I once set up gcc for crossing from cygwin to 68HC1x for a customer. It
worked pretty well, except for small problems in shell scripts here and
I would expect gcc to configure successfully for cygwin-to-NetBSD. Try
asking for help on the Cygnus "crossgcc" mailing list. Being able to build
a kernel might be a bit more challenging, due to minor differences between
BSD and GNU utilities.

Yes, embedded developers, for some reason, guard one of the last bastions of
the Windows empire.
But also important is that a well-conceived cross-build system would be able
to cross from other OS's such as Linux. (For example, I have a customer
that has finally embraced Linux for embedded development. At this stage,
they would rather cross from Linux to NetBSD than have to dual-boot Linux
NetBSD supports crossing from port to port quite well, once you know how to
do it. I've set up a simplified mechanism for cross-building the NetBSD
tree from port to port, which allows non-root builds. If you'd like to try
it, I'd be interested in your comments.

I'm pedalling as fast as I can. I'm also in the market for someone who
wants mpc8xx bad enough to pay to get it into my main work queue.

The general case of *nix (including cygwin) to NetBSD is interesting, yes.
