  cygnus: warn when it's used (flagged as 'obsolete' now)
  
  Support for "Cygnus-style" tree as enabled by the 'cygnus'
  option is now reported as obsolete when the warnings in the
  'obsolete' category are enabled.
  
  See automake bug#11034.
  
  * automake.in (check_cygnus): Report the use of 'cygnus' mode as
  obsolete.
  * NEWS: Update.
  * docs/automake.texi: Minor adjustments.
  * t/cygnus-deprecation.sh: New test.
  * t/list-of-tests.mk: Add it.
  * tests/cygnus-check-without-all.sh: Adjust by calling automake
  with the warnings in the 'obsolete' category disabled.
  * t/cygnus-requires-maintainer-mode.sh: Likewise.
  * t/cygnus-dependency-tracking.sh: Likewise.
  * t/cygnus-imply-foreign.sh: Likewise.
  * t/cygnus-no-installinfo.sh: Likewise.
  * t/cygnus-no-dist.sh: Likewise.
  * t/clean2.sh: Likewise.
  * t/flavor.sh: Likewise.
  * t/txinfo5.sh: Likewise.
  * t/txinfo5b.sh: Likewise.
  * t/library.sh: Remove use of 'cygnus' and 'dejagnu' options,
  and of AM_MAINTAINER_MODE macro.
