I just built binutils 2.17 with these patches from WinAVR, gcc 4.2.0  
(without any patches so far) and avr-libc 1.4.6 and it was successful  
now. I guess I didn't use the actual new-devices-patch for binutils  
before. I didn't look in detail on WinAVR so far, because I don't use  
Windows. ;-)

It would be great to have the 4.2.0 patches in the WinAVR CVS, thanks  
for that in advance! :-)

Best regards,
