The link to the bugzilla appears to be broken, so I'm reporting this
here.

I've installed dm857c.zip on Windows 11.  The following program :

#include <stdio.h>
#include <stdint.h>
int main(void) {
    printf("UINT64_MAX       = %ju = 0x%jx\n", UINT64_MAX,       UINT64_MAX);
    printf("UINT_LEAST64_MAX = %ju = 0x%jx\n", UINT_LEAST64_MAX,
UINT_LEAST64_MAX);
    printf("UINT_FAST64_MAX  = %ju = 0x%jx\n", UINT_FAST64_MAX, 
UINT_FAST64_MAX);
    printf("UINTMAX_MAX      = %ju = 0x%jx\n", UINTMAX_MAX,      UINTMAX_MAX);
}

is rejected with the error "Lexical error: number is not representable"
on lines 4, 5, 6, and 7.  The correct output should be :

UINT64_MAX       = 18446744073709551615 = 0xffffffffffffffff
UINT_LEAST64_MAX = 18446744073709551615 = 0xffffffffffffffff
UINT_FAST64_MAX  = 18446744073709551615 = 0xffffffffffffffff
UINTMAX_MAX      = 18446744073709551615 = 0xffffffffffffffff

The problem is in the definitions of the 64-bit *_MAX macros in
C:\dm\include\stdint.h :

#define UINT64_MAX      18446744073709551615
#define UINT_LEAST64_MAX 18446744073709551615
#define UINT_FAST64_MAX 18446744073709551615
#define UINTMAX_MAX     18446744073709551615

Unsuffixed decimal integer constants are always of some signed type.
These constants exceed ULLONG_MAX, which results in the errors
when they're expanded.

Experiment shows that adding a "ULL" suffix to each of these
constants corrects the problem.
