I can't find a reference to ptrint_t anywhere on either my system,
and the 10 first hits on Google finds it on typedef lines, most
commonly like this:

	typedef unsigned long ptrint_t;


I think ptrdiff_t is more portable. Here's the relevant entry
about ptrdiff_t from /usr/include/obstack.h on my system:

---%<---%<---%<---
/* We need the type of a pointer subtraction.  If __PTRDIFF_TYPE__ is
   defined, as with GNU C, use that; that way we don't pollute the
   namespace with <stddef.h>'s symbols.  Otherwise, include <stddef.h>
   and use ptrdiff_t.  */

#ifdef __PTRDIFF_TYPE__
# define PTR_INT_TYPE __PTRDIFF_TYPE__
#else
# include <stddef.h>
# define PTR_INT_TYPE ptrdiff_t
#endif
---%<---%<---%<---

MySQL seems to have botched that one though. It has this instead:

	typedef long          my_ptrdiff_t;
