  sys_time: allow too-wide tv_sec
  
  * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Allow struct
  timeval even if tv_sec is wider than time_t.  This allows
  OpenBSD 5.1 amd64 and fixes an Emacs porting glitch with utimens.c,
  as without this patch gnulib replaces struct timeval
  and OpenBSD futimes therefore has a type mismatch.
  * doc/posix-headers/sys_time.texi: Mention this.

  @item
  This header file is missing on some platforms:
  MSVC 9.

  @samp{struct timeval} is not defined on some platforms.

  @samp{struct timeval} is defined with a @code{tv_sec} type that is
  narrower than @code{time_t}
  on some native Windows platforms:
  mingw64 in 64-bit mode,
  mingw64 in 32-bit mode when @code{__MINGW_USE_VC2005_COMPAT} is defined,
  MSVC 9 in 64-bit mode,
  MSVC 9 in 32-bit mode when @code{_USE_32BIT_TIME_T} is not defined.
