I agree, more conservative.

 From limits.h of MS Visual Studio:

/* minimum signed 64 bit value */
#define _I64_MIN (-9223372036854775807i64 - 1)
/* maximum signed 64 bit value */
#define _I64_MAX 9223372036854775807i64
/* maximum unsigned 64 bit value */
#define _UI64_MAX 0xffffffffffffffffui64

They use the "i64" suffix instead of "LL" .....

No comment .... :-(

So I will have:

typedef __int64 int64_t;
#define PRId64 "I64d"
#define INT64_MAX _I64_MAX

Regards

Guido
