Well, I think there is probably some arch code that uses 16-bit
that might use a null pointer, or at least a struct that starts
at the 0 address, which would have problems. I think it would
be better to avoid that issue just in case, especially since
this optimization does not save anything in the case of properly
written code.
A warning might be nice though.
If we could turn off the optimization and add a warning, I
would support that. Even if we could only add the warning, then
at least people would know.
