   [The Prime machines suffered from having too many versions of   
   everything.  Page 41 of that quick reference card has a 48 bit pointer   
   format with a bit number in the low 16 bits.  It seems unlikely that a   
   C compiler would use that as a general pointer format since it doesn't   
   fit in any sort of normal int, and it's not what you'd want to point   
   at an int or a function or anything bigger than a char. -John]
