I disagree.  IMHO there is no reason why we should optimize these out at -O0.
We don't optimize out already unused global decls at -O0, I think we should
treat the local ones the same way.

Well, it doesn't even have a value assigned.  So I consider this a valid
"optimization" for -O0.  Does the variable have a location once you inintialize
it?
