The fact that they already have a -fno-delete-null-pointer-checks option
in the compiler seems to demonstrate that they know they are doing
this specifically because it is undefined and they can do whatever
they want (including checking a compiler option to choose a different
thing to do). I guess thinking that the best choice is always
to do what the source code says makes me a member of a looney
minority though :-).
