  Fix per-Makefile.am setting of -Werror.
  
  Before this patch, 'AUTOMAKE_OPTIONS = -Werror' in one
  Makefile.am would carry over to other Makefile.am files
  treated afterwards by the same thread, causing inconsistent
  and unstable exit status values.
  
  * lib/Automake/Channels.pm (dup_channel_setup)
  (drop_channel_setup): Save and restore the setting of
  $warnings_are_errors.
  * tests/werror3.test: New test.
  * tests/Makefile.am: Adjust.
  * NEWS: Update.
