  largefile: sync from Autoconf master
  
  * modules/largefile-required, modules/year2038-required: New modules.
  * MODULES.html.sh, doc/largefile.texi, doc/posix-headers/time.texi:
  * doc/year2038.texi: Document this.
  * m4/largefile.m4: Sync from Autoconf master.
  Conditionalize the workaround on AC_SYS_LARGEFILE_REQUIRED rather
  than on AC_SYS_YEAR2038 so that we replace older but still
  unreleased Autoconf.
  (AC_SYS_LARGEFILE_REQUIRED, AC_SYS_YEAR2038_REQUIRED): New macros.

  @section Large File Support
  
  The Gnulib @samp{largefile-required} module provides support for files
  2 GiB and larger, or with device or inode numbers exceeding 32 bits.
  To this effect, it ensures that types like @code{off_t} and
  @code{ino_t} are 64-bit,
  at least on the following platforms:
  glibc, Mac OS X, FreeBSD, NetBSD, OpenBSD, AIX, HP-UX, IRIX, Solaris,
  Cygwin, mingw, MSVC.
  
  The Gnulib @samp{largefile} module is similar, except that it gives
  @command{configure} an option @samp{--disable-largefile} that
  suppresses support for large files.  This may be useful if the package
  links to other libraries whose user-facing ABIs still require
  @code{off_t} or most other file-related types to be 32-bit on your
  platform.
  
  Both modules also add to @command{configure} an option
  @code{--enable-year2038}, needed on some platforms to access files
  with timestamps past the year 2038.  @xref{Avoiding the year 2038
  problem}.
