You can safely set SS := DS, but you lose the stack overflow
protection.  The two selectors map to the same linear starting
address.  In fact, this "enhancement" does break -fomit-frame-pointer
mode in gcc, which assumes that you can use SS to point to non-stack
things, so it may go away and then SS==DS always.
