   250  //    defines %a as a standalone format specifier that reads a floating-
   251  //    point number; moreover, POSIX.1-2008 provides the same feature
   252  //    using the modifier letter 'm' instead (%ms, %mS, %m[...]).

   254  //    We now follow C99 unless GNU extensions are active and the compiler

   719  //    of those macros must use the following macros for underlying types.
   720  //    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
   721  //    variants of each of the following integer types on this machine.
   722  //
   723  // 	16		-- "natural" 16-bit type (always short)
   724  // 	32		-- "natural" 32-bit type (always int)
   725  // 	64		-- "natural" 64-bit type (long or long long)
   726  // 	LONG32		-- 32-bit type, traditionally long
   727  // 	QUAD		-- 64-bit type, traditionally long long
   728  // 	WORD		-- natural type of __WORDSIZE bits (int or long)
   729  // 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
   730  //
   731  //    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
   732  //    conventional uses of `long' or `long long' type modifiers match the
   733  //    types we define, even when a less-adorned type would be the same size.
   734  //    This matters for (somewhat) portably writing printf/scanf formats for
   735  //    these types, where using the appropriate l or ll format modifiers can
   736  //    make the typedefs and the formats match up across all GNU platforms.  If
   737  //    we used `long' when it's 64 bits where `long long' is expected, then the
   738  //    compiler would warn about the formats not matching the argument types,
   739  //    and the programmer changing them to shut up the compiler would break the
   740  //    program's portability.
   741  //
   742  //    Here we assume what is presently the case in all the GCC configurations
   743  //    we support: long long is always 64 bits, long is always word/address size,
   744  //    and int is always 32 bits.
   745  
   746  // No need to mark the typedef with __extension__.
