--- Comment #7 from Manfred Schwarb <manfred99 at gmx dot ch> ---
Hopefully this rings some bells: The warnings happen
only for parameters:

      real b
      double precision a,c,d
      PARAMETER(a=3.1415927d0)

      DATA c /3.1415927d0/
      d=3.1415927d0

      b=REAL(a)
      b=REAL(a, kind=4)
      b=REAL(c)
      b=REAL(d)
      end


a.f:8:13:

    8 |       b=REAL(a)
      |             1
Warning: Change of value in conversion from 'REAL(8)' to 'REAL(4)' at (1)
[-Wconversion]
a.f:9:13:

    9 |       b=REAL(a, kind=4)
      |             1
Warning: Change of value in conversion from 'REAL(8)' to 'REAL(4)' at (1)

Thanks for your efforts!
