Can someone clarify why the program included outputs 'AB000000' (as I
expect) on 32 bit systems and 'FFFFFFFFAB000000' on 64 bit systems?
where all those 1's came from? what's the portable way of doing this?
sorry for newbie questions like this.


       unsigned long l;
        unsigned char c;

        l = 0L;
        c = 0xAB;
        l |= c << 24;
        printf("%lX\n", l);
