That still doesn't work. The compiler will generate address references to
stack objects itself as will normal things like pointers into an array.

Faced with s = s + 1 for an auto variable the compiler is likely to
generate something like a word increment of &s, but it's not going to
magically put segments in.

The DOS folks spent a long time writing very good compilers - they never
figured out a hack for this; although in many other languages SS != DS
isn't a problem.
