[Python-Dev] C9X information

  This contains a summary of changes.
  Of particular note regarding today's discussion is item #38.  GCC
(at least recent versions) include the required header.  The types are
actually defined in <stdint.h> for GCC; take a look there for the
actual type names.  In my installation, it includes things like this:

/* Exact integral types.  */

/* Signed.  */

/* There is some amount of overlap with <sys/types.h> as known by inet code */
#ifndef __int8_t_defined
# define __int8_t_defined
typedef signed char		int8_t;
typedef short int		int16_t;
typedef int			int32_t;
# if __WORDSIZE == 64
typedef long int		int64_t;
# else
__extension__
typedef long long int		int64_t;
# endif
#endif

/* Unsigned.  */
typedef unsigned char		uint8_t;
typedef unsigned short int	uint16_t;
typedef unsigned int		uint32_t;
#if __WORDSIZE == 64
typedef unsigned long int	uint64_t;
#else
__extension__
typedef unsigned long long int	uint64_t;
#endif


/* Small types.  */

/* Signed.  */
typedef signed char		int_least8_t;
typedef short int		int_least16_t;
typedef int			int_least32_t;
#if __WORDSIZE == 64
typedef long int		int_least64_t;
#else
__extension__
typedef long long int		int_least64_t;
#endif

/* Unsigned.  */
typedef unsigned char		uint_least8_t;
typedef unsigned short int	uint_least16_t;
typedef unsigned int		uint_least32_t;
#if __WORDSIZE == 64
typedef unsigned long int	uint_least64_t;
#else
__extension__
typedef unsigned long long int	uint_least64_t;
#endif


/* Fast types.  */

/* Signed.  */
typedef signed char		int_fast8_t;
#if __WORDSIZE == 64
typedef long int		int_fast16_t;
typedef long int		int_fast32_t;
typedef long int		int_fast64_t;
#else
typedef int			int_fast16_t;
typedef int			int_fast32_t;
__extension__
typedef long long int		int_fast64_t;
#endif

/* Unsigned.  */
typedef unsigned char		uint_fast8_t;
#if __WORDSIZE == 64
typedef unsigned long int	uint_fast16_t;
typedef unsigned long int	uint_fast32_t;
typedef unsigned long int	uint_fast64_t;
#else
typedef unsigned int		uint_fast16_t;
typedef unsigned int		uint_fast32_t;
__extension__
typedef unsigned long long int	uint_fast64_t;
#endif
