Another solution to all these far-memory tricks (and hacks) would be
real far-pointers. How difficult would it be to implement this in
GCC ? This is a FSF issue I presume, but the djgpp community has lot
of pull there.
 
far-pointers are one of the nice things of e.g. Metaware HighC, and the
lack of it in GCC is one of the things that holds me back from
switching. Does anybody know if Metaware C (for Unix) is compatible with
GCC. Could it be used to develop djgpp programs.
