  Gnulib module: readdir
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  MSVC 14.
  @item
  On platforms where @code{off_t} is a 32-bit type, this function may not
  work correctly on huge directories larger than 2 GB.  Also, on platforms
  where @code{ino_t} is a 32-bit type, this function may report inode numbers
  incorrectly.  (Cf. @code{AC_SYS_LARGEFILE}.)

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Although POSIX places no restrictions on @code{d_ino} values, some
  older systems are rumored to return @code{d_ino} values equal to zero
  for directory entries that do not really exist.  Although Gnulib
  formerly attempted to cater to these older systems, this caused
  misbehavior on standard systems and so Gnulib does not attempt to
  cater to them any more.  If you know of any problems caused by this,
  please send a bug report.
