+/* 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. */
