Purpose:

 IZMAX1 finds the index of the element whose real part has maximum
 absolute value.

 Based on IZAMAX from Level 1 BLAS.
 The change is to use the 'genuine' absolute value.

Parameters:

[in]	N	N is INTEGER The number of elements in the vector CX.
[in]	CX	CX is COMPLEX*16 array, dimension (N) The vector whose elements will be summed.
[in]	INCX	INCX is INTEGER The spacing between successive values of CX. INCX >= 1.
