There is a more generic "fix" for the stack overflow.  Make the SS
selector have an expand down limit and be different from DS.  This
was the way it was done in DJGPP V1.x by the way, but breaks using
-fomit-frame-pointer since EBP can't be a generalize offset since
it is based on SS.

There are actually hooks/pieces in the V2 code to turn on an option
to do this (the entire DS_ALIAS stuff gets hacked).  Time to 
implement it completely ran out (as did interest).

This is the way that automatic stack expansion was also going to
be done (catch the signal, fix the arena, resume).
