FYI, there was just something on the GCC mailing list about some 
-Wunreachable-code bug fix. I can't guarantee that it will apply to 
your problem (I haven't looked into the specific GCC Problem Report). 


If you can build your GCC from source then I would suggest trying out 
next week's snapshot to see if that solved your issue. If you're only 
using WinAVR, then check it out on the next WinAVR release, which 
unfortunately probably won't be for another 4-6 weeks.

HTH,
