umm, the problems which occur are when your doing pointer arithmatic and 
storing differences between pointers in integer temp variables (instead of 
ptr_diff_t).  Or storing pointers in integers.  Maybe all the cases in the 
code are just ints being stored in pointers, but I thought I had seen some 
that were not.
