We seem to get this every year or so... just upgrade your compiler and
it will be smart enough to prove that it's wrong here.

I really *don't* want to shut up the compiler forcefully since it will
cause modern compilers to *not* warn if it actually *is* unused - and 0
is not a useful value - this code is tricky enough and we want compiler
help in case we need to modify it in the future.
