stderr of a release build

I've recently upgraded my GCC and it seems to have a new warning
-Wunused-but-set-variable

I promptly compiled ioq3 with it and it vomited a thousand of these everywhere.
Attached is the compile log. I realise it's a huge pain to deal with and
probably some of the warnings will be spurious, but I bet there's at least some
legitimate concerns in there.
