--- Comment #5 from Bud Davis <bdavis at gcc dot gnu.org> ---
As the reporter of this enhancement request, I think it is something that
should be left open.

Low priority, but this was a 'feature' of some f77 compilers in the past.  

Even if no-one ever adds this functionality, those porting old f77 code that
encounter this will be able to see that it is not implemented and they can
infer why it was not added.
