160 unused but set variables in QEMU

[Austin English]

I use gcc from SVN on my desktop:
austin@midna:~/gits/qemu$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.6.0/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ./configure --enable-languages=c,c++
Thread model: posix
gcc version 4.6.0 20100726 (experimental) (GCC)

which enables a new warning, 'unused-but-set'. Normally, this wouldn't be a big deal, just an annoyance, but since QEMU builds with -Werror, it causes problems.

Easy enough to workaround with 'make -k'. To make it a bit easier on you, I ran 'make -k ; make -k &> make.txt', and attached that here, so you can easily find the 160 cases that should be fixed in qemu without needing gcc 4.6.

Forgot to add, this is with git head, commit cc597832119dd1504f1c1536bb5f903d8970af2a.

We fixed all our unused-but-set compiler warnings some time before the release of qemu 1.0, so I'm closing this bug as fixed.
