    Purpose   
    =======   

    ICOPY copies an integer vector x to an integer vector y.   
    Uses unrolled loops for increments equal to 1.   

    Arguments   
    =========   

    N       (input) INTEGER   
            The length of the vectors SX and SY.   

    SX      (input) INTEGER array, dimension (1+(N-1)*abs(INCX))   
            The vector X.   

    INCX    (input) INTEGER   
            The spacing between consecutive elements of SX.   

    SY      (output) INTEGER array, dimension (1+(N-1)*abs(INCY))   
            The vector Y.   

    INCY    (input) INTEGER   
            The spacing between consecutive elements of SY.
