| <p>The GNU Fortran compiler implements |
| ISO/IEC 1539:1997 (Fortran 95). As such, it can also compile essentially all |
| standard-compliant Fortran 90 and Fortran 77 programs. It also supports |
| the ISO/IEC TR-15581 enhancements to allocatable arrays. |
| |
| <p>GNU Fortran also have a partial support for ISO/IEC 1539-1:2004 (Fortran |
| 2003), ISO/IEC 1539-1:2010 (Fortran 2008), the Technical Specification |
| <code>Further Interoperability of Fortran with C</code> (ISO/IEC TS 29113:2012). |
| Full support of those standards and future Fortran standards is planned. |
| The current status of the support is can be found in the |
| <a href="Fortran-2003-status.html#Fortran-2003-status">Fortran 2003 status</a>, <a href="Fortran-2008-status.html#Fortran-2008-status">Fortran 2008 status</a> and |
| <a href="TS-29113-status.html#TS-29113-status">TS 29113 status</a> sections of the documentation. |
| |
| <p>Additionally, the GNU Fortran compilers supports the OpenMP specification |
| (version 3.1, <a href="http://openmp.org/wp/openmp-specifications/">http://openmp.org/wp/openmp-specifications/</a>). |
