We want the better optimizations that "new C" enables more than we
want the semantics of "traditional C". Thus, anything that depends on
"traditional C" should be fixed.

I also think that very little of the kernel is sufficently low-level
that the "traditional C" argument is even remotely plausable; most of
it is written with higher-level language concepts and data structures,
and if it were practical, it would be better to write it in some
higher-level language.
