   This just works in a test program I'm compiling with:   
   - Borland/Turbo C/C++, large model   
   - Open Watcom, large model   
   - Smaller C, huge, unreal and DPMI models   
      
   The definition for Smaller C is:   
   #define MK_FP(s,o)   ((void*)(((unsigned long)(s) << 4) + (unsigned)(o)))
