/* The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
   macros for each of the OS types we define below.  The definitions
   of those macros must use the following macros for underlying types.
   We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
   variants of each of the following integer types on this machine.

16		-- "natural" 16-bit type (always short)
	32		-- "natural" 32-bit type (always int)
	64		-- "natural" 64-bit type (long or long long)
	LONG32		-- 32-bit type, traditionally long
	QUAD		-- 64-bit type, traditionally long long
	WORD		-- natural type of __WORDSIZE bits (int or long)
	LONGWORD	-- type of __WORDSIZE bits, traditionally long

We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
   conventional uses of `long' or `long long' type modifiers match the
   types we define, even when a less-adorned type would be the same size.
   This matters for (somewhat) portably writing printf/scanf formats for
   these types, where using the appropriate l or ll format modifiers can
   make the typedefs and the formats match up across all GNU platforms.  If
   we used `long' when it's 64 bits where `long long' is expected, then the
   compiler would warn about the formats not matching the argument types,
   and the programmer changing them to shut up the compiler would break the
   program's portability.

Here we assume what is presently the case in all the GCC configurations
   we support: long long is always 64 bits, long is always word/address size,
   and int is always 32 bits.  */
