RE: gawk printf format problem with negative numbers

[Shaffer, Kenneth]

The stdint.h is broke:  needs LL on the end tacked on the end of several values:

line 74:
#define INT64_MIN (-9223372036854775808)

line 79:
#define INT64_MAX (9223372036854775807)

line 91:
#define INT_LEAST64_MIN (-9223372036854775808)

line 96:
#define INT_LEAST64_MAX (9223372036854775807)

line 108:
#define INT_FAST64_MIN (-9223372036854775808)

line 113:
#define INT_FAST64_MAX (9223372036854775807)

lines 128 and 129:
#define INTMAX_MIN (-9223372036854775808)
#define INTMAX_MAX (9223372036854775807)

Probably not a problem on normal unix flavors of this header file.  Thanks for helping me narrow this down. After making the above changes and recompiling gawk, it returns the correct result.

This compiler is buggy

#define INTMAX_MIN (-9223372036854775808)
#define INTMAX_MAX (9223372036854775807)
#define UINTMAX_MAX (18446744073709551615ULL)

The above must be 64-bit values. Does gcc handle such large values on a PC? If so, would you happen to know what compile options might make use of it?

What is the value of INTMAX_MIN on your host?  Can you reproduce the problem
with a small C program?  Something like this:

#include <stdio.h>
#include <inttypes.h>
double tmpval = -1234;
int main (void)
{
  if (tmpval < INTMAX_MIN)
    printf ("This compiler is buggy\n");
}
