I have heard Linus and Alan Cox say that they should not have to change
the kernel because it is GCC that is broken in this respect. It leaves
me wondering why the development kernels don't incur this problem, ie,
they "fixed" it there (or just did it right from the beginning), so why
not in .34 .
But, who knows.
