   It is possible if you manipulate the segment.   
      
   C compilers, even in the large memory model,   
   will not do that for you, because it is inefficient.   
      
   They wrap back to 0 when you increment   
   past ffff   
      
   Only a huge pointer will get the compiler to   
   manipulate the segment when you attempt to   
   go past ffff (effectively).   
      
   As soon as a decision is made to manipulate   
   a segment, you have a problem.   
      
   That's the point at which software is   
   typically tied down to a 4 bit segment shift.   
      
   It doesn't need to be like that though.   
      
   A flexible segment manipulation method   
   could be implemented.   
      
   Yes, there's a cost, but huge pointers are   
   rare in the first place.
