perf: Turn off compiler warnings for flex and bison generated files (09c0211c) · Commits · 戴 / test

We don't know what types of warnings different versions of flex and bison combined with different versions of gcc is going to generate, so just punt and don't warn about anything. This fixes the build of perf for me on an openSUSE 12.1 system. Signed-off-by:
