| In this implementation the <literal>-std=gnu++14</literal> or |
| <literal>-std=c++14</literal> flag must be used to enable language |
| and library |
| features. See <link linkend="manual.intro.using.flags">dialect</link> |
| options. The pre-defined symbol |
| <constant>__cplusplus</constant> is used to check for the |
| presence of the required flag. |
| GCC 6.1 was the first release with non-experimental C++14 support, |
| so the API and ABI of features added in C++14 is only stable |
| since that release. |

| This status table is based on the table of contents of ISO/IEC 14882:2014. |
| Some subclauses are not shown in the table where the content is unchanged |

| <para> |
| This section describes the C++14 and library TS support in mainline GCC, |

| <emphasis>2.1 POSIX conformance [fs.conform.9945]</emphasis> |
| The behavior of the filesystem library implementation will depend on |
| the target operating system. Some features will not be supported |
| on some targets. Symbolic links and file permissions |
| are not supported on Windows. |
| </para> |
| <para> |
| <emphasis>15.30 Rename [fs.op.rename]</emphasis> |
| On Windows, <code>experimental::filesystem::rename</code> |
| is implemented by calling <code>MoveFileExW</code> and so |
| does not meet the requirements of POSIX <code>rename</code> |
| when one or both of the paths resolves to an existing directory. |
| Specifically, it is possible to rename a directory so it replaces |
| a non-directory (POSIX requires an error in that case), |
| and it is not possible to rename a directory to replace another |
| directory (POSIX requires that to work if the directory being |
| replaced is empty). |
