[Bug fortran/33439] OpenMP: Incorrect error message for chunksize variable

[jakub at gcc dot gnu dot org]

I think the standard is very vague here.
First consider:
!$omp parallel default(none)
  call something
!$omp do schedule(static, chunksize)
  do i=1,100
    call somethingelse
  done
!$omp end do
!$omp end parallel

Do you agree that this must issue an error?  Here page 36 only says that
if there was say !$omp do schedule(static, chunksize) private(chunksize), then
schedule would use the outer chunksize, while inside of the loop would be a
different, privatized, variable.  I can't see how chunksize wouldn't count here
as a reference of that variable inside of the parallel.

Now, consider:
!$omp parallel default(none)
!$omp do schedule(static, chunksize)
  do i=1,100
    call somethingelse
  done
!$omp end do
!$omp end parallel

I believe this falls to the same category as the previous one.
Now, for the combined parallel it is very unclear, but doesn't section 2.6
say they have the same semantics as the above?
