! Function: psb_znrm2_weight_vect
! Computes the weighted norm2 of a distributed vector with respect to a mask
! contained in the vector id.
!
! norm2 := sqrt ( (w(id > 0).*X(id > 0))**C * (w(id > 0).*X(id > 0)))
!
! Arguments:
! x - type(psb_z_vect_type) The input vector containing the entries of X.
! w - type(psb_z_vect_type) The input vector containing the entries of W.
! id - type(psb_z_vect_type) The inpute vector containing the mask
! desc_a - type(psb_desc_type). The communication descriptor.
! info - integer. Return code
! global - logical(optional) Whether to perform the global reduction, default: .true.
