[platform-testers] new snapshot available: gzip-1.9.15-17f5c

[Jim Meyering]

I'm going to release gzip-1.10 this year.
Any testing would be most appreciated.
See the NEWS below.

      gzip: port better to mingw
      gzip: make the output more reproducible
      gzip: port better to mingw again
      Fix some theoretical races in signal handling
      gzip: fix bug in signal-handling fix
      * gzip.c (remove_output_file): Fix typo.
      gzip: fix use of uninitialized memory

====================================================
NEWS:

** Changes in behavior

  Compressed gzip output no longer contains the current time as a
  timestamp when the input is not a regular file.  Instead, the output
  contains a null (zero) timestamp.  This makes gzip's behavior more
  reproducible when used as part of a pipeline.  (As a reminder, even
  regular files will use null timestamps after the year 2106, due to a
  limitation in the gzip format.)

** Bug fixes

  A use of uninitialized memory on some malformed inputs has been fixed.
  [bug present since the beginning]

  A few theoretical race conditions in signal handers have been fixed.
  These bugs most likely do not happen on practical platforms.
