If GCC winds up having to fix the bug in the compiler itself for PPC, then everyone could have the option of using a kernel fix or a compiler fix. But how are you going to do the kernel fix? What if the user did an integer divide and not a modulo? I suppose you could just say the result is undefined and patch up the quotient too.
