...
checking for stdint.h... yes
...
checking whether stdint.h conforms to C99... yes
...
so, it seems there is a substandard system stdint.h that isn't defining the
macros directly...
>From inttypes.h (which is included by stdint.h):
#define INT8_C(__c) (__c)
#define UINT8_C(__c) __CONCAT_U__(__c)
#define INT16_C(__c) (__c)
#define UINT16_C(__c) __CONCAT_U__(__c)
#ifdef __LP64__
#define INT32_C(__c) (__c)
#define UINT32_C(__c) __CONCAT_U__(__c)
#else /* __LP64 */
#define INT32_C(__c) __CONCAT__(__c,l)
#define UINT32_C(__c) __CONCAT__(__c,ul)
#endif /* __LP64 */
#define INT64_C(__c) __CONCAT_L__(__c,l)
#define UINT64_C(__c) __CONCAT_L__(__c,ul)
#define INTMAX_C(__c) __CONCAT_L__(__c,l)
#define UINTMAX_C(__c) __CONCAT_L__(__c,ul)
#define INT8_MAX INT8_C(127)
#define INT16_MAX INT16_C(32767)
#define INT32_MAX INT32_C(2147483647)
#define INT64_MAX INT64_C(9223372036854775807)
#define INT8_MIN (-INT8_MAX - 1)
#define INT16_MIN (-INT16_MAX - 1)
#define INT32_MIN (-INT32_MAX - 1)
#define INT64_MIN (-INT64_MAX - 1)
Not sure where to go from here though :(
Cheers,
Gary
