I could reproduce the bug. (Sorry for the delay) Does it compile fine with old avr-gcc but the new avr-libc? I will also try with avr-gcc-4.5.2. Hmm, yes it seem to depend only on avr-gcc. The new release 4.5.2 does not fix the problem. I am quite busy these days. I will try and file a bug against gcc. If you have time to do so, please do.
