[Bug fortran/31162] New: missing warning for real do-loops with implicit typed variables

[manfred99 at gmx dot ch]

real r
      do r=1.0,2.0
        print*,r
      enddo
      end

gives
legacy.f:2.10:

      do r=1.0,2.0
         1
Warning: Obsolete: REAL DO loop iterator at (1)


which is ok, however
      do r=1.0,2.0
        print*,r
      enddo
      end
compiles without warning!

the same for
      implicit real(a-z)
      do r=1.0,2.0
        print*,r
      enddo
      end

Additionally: It seems this warning is tied to -std=legacy, perhaps
it would make more sense to tie it to -Wsurprising as it was the case for g77.

------- Comment #1 from jvdelisle at gcc dot gnu dot org  2007-06-12 00:22 -------
There are two different code paths in the compiler for implicit and implicit
none.  I will see if I can find the spot for this check to be added.  I came
across it once before.

Found the problem.  We are checking the iterator variable type but not the
start, end, and step value types.  Patch will come sometime in the next few
days.
