--- Comment #6 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The discussion has started at
https://gcc.gnu.org/ml/fortran/2013-02/msg00079.html and died at
https://gcc.gnu.org/ml/fortran/2013-03/msg00048.html.

Fritz Reese has offered to implement DEC Extensions at
https://gcc.gnu.org/ml/fortran/2014-09/msg00255.html, but the thread died at
https://gcc.gnu.org/ml/fortran/2014-10/msg00081.html.

IMO f77 extensions should be frozen: bugs being documented and not fixed,
extension
requests put under 6.2 Extensions not implemented in GNU Fortran.
