Ups. eCos 2.0 is terribly old.

eCos 3.0 was carefully tested on Linux and cygwin. I'm sorry, I don't
use cygwin, but a lot of eCosers use it. I agree with that what cygwin
does add new (not eCos related) problems for developers.

Then use Linux. Just now I'm writing a success story for my vis-a-vis
friend about: eCos 3.0 + OpenOCD (today's SVN trunk) + a cheap parallel
JTAG wiggler from Olimex + arm-eabi-gdb + printf. But, I use Linux.
