The powerpc emulator should work on Cygwin.

However, compared to other solutions these are somewhat limited.

You could use the bochs simulator, which will give you a richer
"hardware" environment. Or use vmware.

I would actually recommend you use Linux, even when there are ways you
can work on XP. Although Cygwin works, it can be a pain. Things work
easier on Linux, since most of the tools have a Unix/Linux history and
have later been made to work on Cygwin. Linux also allows you to run
eCos as a process, using the synthetic target.

This is a very flexible solution, since with a bit of work you can
emulate your peripherals of your real hardware. I've implemented a
complete network of devices by making an emulator for the physical
layer of our network device, over TCP/IP sockets with a server process
which does packet loss, corruption etc, and been able to debug the
protocol stacks running in eCos. The synth target is nice for quick
compile/run/crash/debug cycles since you don't have to wait 60 seconds
for JTAG to program your flash on your hardware etc, and you have the
full power of native GDB etc.
