So far, that's a statement about the future, since the Darwin kernel
(at least) doesn't support more than 2G (or is it 4G?) of RAM. No
doubt, when such a kernel is created, it'll enhance the sysctl
interface to be able to return larger values, and we'll need to
enhance GCC to keep up; but there's no point doing that until we know
what the new interface is.
