    This is a question that would best be asked in the programming forum, rather than as a blog post. But, since I'm a nice guy (this is on OpenBSD-CURRENT, but for Linux it should be quite similar):

    Code:
    $ cat test.c
    #include <stdio.h>
    
    /* stupid test program */
    int main()
    {
            int a,b;
            a = 7814;
            b = 5612;
            printf("a: %i, b: %i\n", a, b);
            a = a ^ b;
            printf("a: %i, b: %i\n", a, b);
            b = a ^ b;
            printf("a: %i, b: %i\n", a, b);
            a = a ^ b;
            printf("a: %i, b: %i\n", a, b);
            return 0;
    }
    
    # compile normally...
    $ gcc test.c         
    $ ls -lha a.out      
    -rwxr-xr-x  1 user  user   6.9K Aug  8 09:36 a.out
    $ ldd a.out  
    a.out:
