If a compiler doesn't support long long, it should fail to compile any
program that uses it. If you're getting a runtime error, something
else is going on. Perhaps the compiler supports long long but the
runtime library doesn't. We have no idea what "error code -1460"
might mean, and we can't guess what the problem is without seeing
actual code.
Try these programs:
========================================
#include <stdio.h>
#include <limits.h>
int main(void)
{
printf("long long is %d bits\n", (int)sizeof(long long) * CHAR_BIT);
return 0;
}
========================================
(output should be "long long is 64 bits")
========================================
#include <stdio.h>
int main(void)
{
long long x = 42;
printf("x = %d\n", (int)x);
return 0;
}
========================================
(output should be "x = 42")
========================================
#include <stdio.h>
#include <limits.h>
int main(void)
{
long long x = LLONG_MAX;
printf("x = %lld\n", x);
return 0;
}
========================================
(output should be "x = 9223372036854775807")
The correct output may vary in the unlikely event that long long is
bigger than 64 bits.

We must do something. This is something. Therefore, we must do this.
