   I think the result of subtracting two pointers can be wider than an int, 
   can't it?  If so, casting to an int is not right, and the format should 
   be changed to %ld.
   
   (Yes, this is nitpicking, but if we are to fix this warning, might as 
   well do it right ;-)
   
Aren't there standard printf format strings for ptrdiff_t, that is
what this thing is.
