patch

This patch fixes the problem in the PR and addresses a few
niggles I found as I poked gfortran.  Some of those errors
don't occur without this patch.

program p
   complex, parameter :: x(0) =3D 2
!   complex :: x(0) =3D 2            ! { dg-error "more values than variabl=
es" }
!   complex :: x(1) =3D 2            ! { dg-error "already is initialized" }
!   complex :: x =3D 2               ! { dg-error "already is initialized" }
!   complex :: x(1)                ! Works (as expected?)
!   complex :: x(0)                ! { dg-error "more values than variables=
" }
   data x%re /3.0/
   print *, x%re
end=
