This gives an error on g++-3.3 
and warnings on gcc-3.3 or g++ with -fpermissive.

I think the max value is correct because max + 1 --> negative max.

The program output:

jim@sun:/usr/local/645/sal$ ./type_test
max + 1  =      -9223372036854775808
max - 1  =       9223372036854775806
max      =       9223372036854775807, size = 8

The compiler messages:

jim@sun:/usr/local/645/sal$ g++  -o type_test type_test.c
type_test.c: In function 	nt main()':
type_test.c:7: error: integer constant is too large for "long" type

The code:

jim@sun:/usr/local/645/sal$ cat type_test.c
#include <stdio.h>
typedef long long sal_Int64;
sal_Int64 bit64;
#define SAL_MAX_INT64 ((sal_Int64) 0x7FFFFFFFFFFFFFFF)
int main(void)
{
        bit64 = SAL_MAX_INT64 ;
        printf("max + 1\t =\t%lld\n", SAL_MAX_INT64 + 1);
        printf("max - 1\t =\t %lld\n", SAL_MAX_INT64 - 1);
        printf("max\t =\t %lld, size = %d\n", bit64, sizeof(sal_Int64));
        return(0);
}
