Description: (newer) Debian log4cxx needs C++17 and used smart pointers.
  This patch just enables C++17 for the build and using smart pointers
  where needed.
Author: Tobias Frost <tobi@debian.org>
Forwarded: not yet. log4cxx 0.14 will come with some preprocessor macros that will enable properly gating the new code.
