Thanks a lot for this hint. I indeed had not patched binutils. Doing so solved a lot of problems. However, the gcc build still does not go through completely. It stops in one avr subdir:

Running configure in multilib subdir avrtiny10

configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1
make: *** [all] Error 2

When I move avrtiny10 away

	mv avrtiny10 avrtiny10_

the gcc build succeeds. But this gets me into trouble when building avr-libc! :-( So I guess I have to figure out what the problem is with this avrtiny10 subdir! The config.log says

...

configure: exit 1

I have no idea what this means and how this can be fixed. I applied all 20 gcc patches one after the other and all went through without error messages (see below). Still the tree does not build. I am rather clueless here! :-(

Hints still greatly appreciated!!

Thanks a lot,

 Andreas
