scsum1

 NAME
      SCSUM1 - take the sum of the absolute values of a complex
      vector and returns a single precision result

 SYNOPSIS
      REAL FUNCTION SCSUM1( N, CX, INCX )

          INTEGER   INCX, N

          COMPLEX   CX( * )

 PURPOSE
      SCSUM1 takes the sum of the absolute values of a complex
      vector and returns a single precision result.

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

 ARGUMENTS
      N       (input) INTEGER
              The number of elements in the vector CX.

      CX      (input) COMPLEX array, dimension (N)
              The vector whose elements will be summed.

      INCX    (input) INTEGER
