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.
