/* XXX A note on the perl source internal type system.  The
   original intent was that I32 be *exactly* 32 bits.

   Currently, we only guarantee that I32 is *at least* 32 bits.
   Specifically, if int is 64 bits, then so is I32.  (This is the case
   for the Cray.)  This has the advantage of meshing nicely with
   standard library calls (where we pass an I32 and the library is
   expecting an int), but the disadvantage that an I32 is not 32 bits.
   Andy Dougherty	August 1996

   In the future, we may perhaps want to think about something like
    #if INTSIZE == 4
	typedef I32 int;
    #else
    #  if LONGSIZE == 4
	    typedef I32 long;
    #  else
    #    if SHORTSIZE == 4
	    typedef I32 short;
    #    else
	    typedef I32 int;
    #    endif
    #  endif
    #endif

   except that still won't work if a system has no integral type
   with a size that is 32 bytes.

   Further, we need to know about PTRSIZE == sizeof(void *) and
   DOUBLESIZE == sizeof(double) if we really want to try to handle
   32/64-bit combinations.  Finally, we might also need to know
   HAS_LONG_DOUBLE and LONG_DOUBLESIZE.

   For the moment, these are only mentioned here so metaconfig will
   construct Configure to figure out the various sizes.

	261	Further, if you try LEAKTEST, you'll also end up calling
