  Gnulib module: chown

  Portability problems fixed by Gnulib:
  @itemize
  @item
  Some platforms fail to detect trailing slash on non-directories, as in
  @code{chown("link-to-file/",uid,gid)}:
  macOS 14, FreeBSD 7.2, AIX 7.3.1, Solaris 9.
  @item
  Some platforms fail to update the change time when at least one
  argument was not @minus{}1, but no ownership changes resulted:
  OpenBSD 7.2.
  @item
  When passed an argument of @minus{}1, some implementations really set the owner
  user/group id of the file to this value, rather than leaving that id of the
  file alone:
  some very old platforms.
  @item
  When applied to a symbolic link, some implementations don't dereference
  the symlink, i.e.@: they behave like @code{lchown}:
  some very old platforms.
  @item
  This function is missing on some platforms; however, the replacement
  always fails with @code{ENOSYS}:
  mingw, MSVC 14.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function sometimes fails with @code{EACCES} when the failure is
  due to lack of appropriate privileges (@code{EPERM}), not to
  search permission denied on the file name prefix (@code{EACCES}):
  Linux kernel 5.15 with glibc 2.35 and a CIFS v1 file system
  (see @url{https://bugs.gnu.org/65599}).
  @end itemize
