d1dc9cf: stdint.h: use correct type for INT64_MAX (#11647)
int64_t is signed. Although it does not make a difference by itself, because
INT64_MAX is still a valid number for uint64_t (UL), the later INT64_MIN
declaration depends on INT64_MAX, and therefore got implicitly casted to
unsigned type.
This fixes the following program on a x86_64 system:
#include <stdint.h>
int main() {
int64_t test = 5;
if (test < INT64_MIN)
return 1;
return 0;
}
This is a regression since commit 1d13a609 ("stdint.h: define
[U]INT64[MAX|MIN]
with [U]L on x86_64").
