| The two sections below detail the extensions to standard Fortran that are |
| implemented in GNU Fortran, as well as some of the popular or |
| historically important extensions that are not (or not yet) implemented. |
| For the latter case, we explain the alternatives available to GNU Fortran |
| users, including replacement by standard-conforming code or GNU |
| extensions. |
