+/* 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.  */
