I now stopped to include ecj.jar in the main compilation and will attend 
to that later when I'm finally able to compile a host=mingw target=mingw 
compiler. I think it's very likely that I'll just compile ecj.jar myself 
after the main compilation.
Shall I add a bugreport so that this won't be forgotten?
