...
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,
