/* 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).

	76	original intent was that I32 be exactly 32 bits.
	77
	78	Currently, we only guarantee that I32 is at least 32 bits.
	79	Specifically, if int is 64 bits, then so is I32. (This is the case
	80	for the Cray.) This has the advantage of meshing nicely with
	81	standard library calls (where we pass an I32 and the library is
	82	expecting an int), but the disadvantage that an I32 is not 32 bits.

	382	XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96	383	safemalloc() in the source, so LEAKTEST won't pick them up.
	384	Further, if you try LEAKTEST, you'll also end up calling
	385	Safefree, which might call safexfree() on some things that weren't
	386	malloced with safexmalloc. The correct "fix" to this, if anyone
	387	is interested, is to ensure that all calls go through the New and
	388	Renew macros.
