/* 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

   There is no guarantee that there is *any* integral type with
   exactly 32 bits.  It is perfectly legal for a system to have
   sizeof(short) == sizeof(int) == sizeof(long) == 8.

   Similarly, there is no guarantee that I16 and U16 have exactly 16
   bits.

   For dealing with issues that may arise from various 32/64-bit 
   systems, we will ask Configure to check out 
   	SHORTSIZE == sizeof(short)
   	INTSIZE == sizeof(int)
   	LONGSIZE == sizeof(long)
	LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG)
   	PTRSIZE == sizeof(void *)
	DOUBLESIZE == sizeof(double)
	LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE).
    Most of these are currently unused, but they are mentioned here so
    metaconfig will include the appropriate tests in Configure and
    we can then start to consider how best to deal with long long
    variables.

	257	Further, if you try LEAKTEST, you'll also end up calling
	258	Safefree, which might call safexfree() on some things that weren't
