bug#29240: new snapshot available: gzip-1.8.40-9dff

[Jim Meyering]

Here's another pre-release snapshot.
Please give it a whirl and report the results.
Thanks again for all the feedback on the last one.

The sole change to NEWS is this revamped paragraph:

  When converting from system-dependent time_t format to the 32-bit
  unsigned MTIME format used in gzip files, if a timestamp does not
  fit gzip now substitutes zero instead of the timestamp's low-order
  32 bits, as per Internet RFC 1952.  When converting from MTIME to
  time_t format, if a timestamp does not fit gzip now warns and
  substitutes the nearest in-range value instead of crashing or
  silently substituting an implementation-defined value (typically,
  the timestamp's low-order bits).  This affects timestamps before
  1970 and after 2106, and timestamps after 2038 on platforms with
  32-bit signed time_t.  [bug present since the beginning]
