| Gnulib module: fchownat |

| Portability problems fixed by Gnulib: |
| @itemize |
| @item |
| This function is missing on some platforms: |
| glibc 2.3.6, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, |
| AIX 5.1, HP-UX 11, IRIX 6.5, Cygwin 1.5.x, mingw, MSVC 14. |
| But the replacement function is not safe to be used in libraries and |
| is not multithread-safe. Also, the replacement may fail to change |
| symlinks if @code{lchown} is unsupported, or fail altogether if |
| @code{chown} is unsupported. |
| @item |
| This function is declared in @code{<sys/stat.h>}, not in @code{<unistd.h>}, |
| on some platforms: |
| Android 4.3. |
| @item |
| Some platforms fail to detect trailing slash on non-directories, as in |
| @code{fchown(dir,"link-to-file/",uid,gid,flag)}: |
| Solaris 9. |
| @item |
| Some platforms mistakenly dereference symlinks when using |
| @code{AT_SYMLINK_NOFOLLOW}: |
| Linux kernel 2.6.17. |
| @item |
| This function does not fail for an empty filename on some platforms: |
| Linux with glibc < 2.11. |
