COMPLEX() and CMPLX() are not the same thing with gfortran.

% cat a.f90
program foo
  print *, kind(cmplx(1.d0,1.d0))
  print *, kind(complex(1.d0,1.d0))
end program foo

% gfortran11 -o z a.f90 && ./z
           4
           8

I have no standing with J3, but I certainly hope someone
who does would object to the needless duplication of an
intrinsic procedure that perpetuates the problem with 
the default kind for CMPLX() in the absence of the third
actual argument KIND=.
