[Jack Howarth]

Steve,
   For this patch there is only a single section which doesn't
apply cleanly to trans-expr.c...

+               /* Argument list functions %VAL, %LOC and %REF are signalled

              else
                {
                  gfc_conv_expr_reference (&parmse, e);

Other than that the backport looks to be trivial.
