There is yet another possibility ;)
The ccc-analyzer could simply be buggy in this case. Would be
interesting to look at the optimized intermediate code whether this gets
optimized out. I think it probably doesn't, but who knows.
The dangling else warnings could also be resolved by simply adding
braces. It doesn't add to the code size, and the times when developers
where paid by LoC are long over (I hope).
