-/* 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, always 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. */
