gcc 4.6.0 causes build of kernel26-lts-ck to fail [SOLVED]

Ever since the bump to gcc 4.6.0, I have been unable to build my kernel26-lts-ck package. It worked fine under the previous version of gcc. Here are the last few lines (note that that "warning: variable ‘xxx’ set but not used [-Wunused-but-set-variable]" is EVERYWHERE since 4.6.0.

Note: this happens at the "make modules" step of the process; the "make bzImage" completes without indecent.

In file included from /dev/shm/kernel26-lts-ck/src/linux-2.6.35/arch/x86/include/asm/hardirq.h:5:0,
                 from include/linux/hardirq.h:10,

Thoughts and suggestion are appreciated.

The actual halting build error occurs before this. Warnings don't stop a kernel build.

I don't think the warning are relevant is what I meant to say... I have no idea what is halting the build though...

Can someone else confirm this behavior? In the mean time, I opened a flyspray task. In this in upstream or something in the Arch packages?

And just to keep all the information here too... I guess this is the patch you need:

To echo what I put in the bugreport, acknowledgment to Allan for solving this problem: the aforementioned patch did the trick/AUR package updated and all is well again.
