Fixed and fixed.

I think the use of -Wall -Werror has been very good for us. It catches little
errors slip by because what is only a warning on one platform is actually an
error on another platform. 

I care about nearly all warnings. And I care about future types of warnings in
future compiler releases. I specifically exempt a few warnings (-Wno-long-long)
for ones that I don't care about it, but I want everything else watched.

So... what warning did you see? Have a patch yet?
