It is possible...you just need a lot of bleeding edge tools.

I have recently build a m68k-coff compiler c/w stdc++ and newlib using:

Gnu-win32 beta 18 tools (the basic building blocks)
Sergey Okhapkin's Coolview cygwin.dll replacement
EGCS-1.0 binaries from Mumit Khan
a build and install of "bison-1.25" which seems to be needed for doing
builds of;
EGCS (version obtained via CVS at around 30/1/98)
binutils-2.8.1.0.18 obtained a while back from
ftp.yggdrasil.com/private/hjl (see the EGCS FAQ for details)
newlib-1.8.0(with Joel Sherril's RTEMS 4 patches)(which I think fix a few
build problems but I'm not sure)

There's a few hacks required along the way to get EGCS to build GCC/EGCS
properly(thanks to Mumit for helping with that one!) and the makefile needs
to be tweeked in a few places after configure....but it can be build
relatively cleanly.

Alternatively you could pick up my "gnu-win32 source" build aimed primarily
at the ColdFire from http://www.calm.hw.ac.uk/davidf/coldfire.htm or wait
around a week until I clean up my build/install tree and release the new
version which handles non coldfire targets neatly.

hmmm. I agree with you there...I test all "development" versions of EGCs on
Linux first to check that they build and compile code correctly before I
even think about win32...why? Complete toolchain rebuild takes 1hour 1 mins
under Linux on my P100 64MB SDRAM or 3-4hours on an AMD K6-200 under
NT....The resulting toolchain is just as good and almost as quick but any
errors in the build process are expensive!

P.S. I thought that the RTEMS list was rtems@oarcorp.com these days? My
