Subject: [PATCH] Avoid unknown warning warnings and fix -Werror on macosx.
clang on macosx does not support -Wunused-but-set-variable; adding the flag
causes additional warnings about the flag. As a more generalized fix, use
-Werror when checking compiler flag support in order to avoid using
unsupported warning flags.
