try unsigned and you'll see:

        pushl   %ebp
        movl    %esp, %ebp
        movl    8(%ebp), %edx
        movl    %edx, %eax
        sall    $2, %eax
        addl    %edx, %eax
        leal    0(,%eax,4), %edx
        addl    %edx, %eax
        leal    0(,%eax,4), %edx
        addl    %edx, %eax
        leal    0(,%eax,8), %edx
        movl    $274877907, %eax
        mull    %edx
        movl    %edx, %eax
        shrl    $6, %eax
        leave
        ret
