I am by no means an expert here, but I am sure RTEMS 4.7 uses gcc-4.1.1 
so even though you have built tools from the RTEMS site, I don't think 
they will work with 4.7.

Can you provide more details here, we use the m68k tools, and have hand 
built both our Cygwin version and Mingw version (currently use).  I have 
both Cygwin and Mingw on my machine.

Have you considered using MSYS (mingw) as your build environment, it 
seems to co-exist better with windows tools than the cygwin environment. 
  I really only have Cygwin left, as we used to use Cygwin as our build 
environment and we have legacy products running on RTEMS4.5 and old 
tools which we have under Cygwin.  Everything new is done under MSYS.

I hope this helps.

regards,

Ian Caddy
