| |
| <p>The GNU Fortran compiler is the successor to <code>g77</code>, the Fortran |
| 77 front end included in GCC prior to version 4. It is an entirely new |
| program that has been designed to provide Fortran 95 support and |
| extensibility for future Fortran language standards, as well as providing |
| backwards compatibility for Fortran 77 and nearly all of the GNU language |
| extensions supported by <code>g77</code>. |
