(char *)0 vs 0 vs (int *)0

[DSullivan.CSC_SDO%hi-multics at sri-unix.UUCP]

 On your Honeywell Level-6 GCOS system, there are a few interesting
 sizeof values:
 sizeof(int) == 2
 sizeof(char *) == 6
 sizeof(parm *) == 6
 sizeof(int *)  == 4   /* withing structures */ Now what size of 0 do
you want this time!  It takes Lint to figure out why it dumped core on
well defined and working PDP-11 or VAX code.  Bleck.
