patch 9.0.1823: Autoconf 2.69 too old Commit: https://github.com/vim/vim/commit/a96d544bc355b1a6021feccf5fa2bd5659bc5269 Author: Illia Bobyr <illia.bobyr@gmail.com> Date: Wed Aug 30 16:30:15 2023 +0200 patch 9.0.1823: Autoconf 2.69 too old Problem: Autoconf 2.69 too old Solution: Migrate to Autoconf 2.71 Autoconf 2.69 is almost 10 years old. And 2.71 is also a few years old as well. Should be pretty well tested by now. It brings a lot of improvements and there seems to be an ongoing work on autoconf 2.72 already. This change just addresses two minor changes `autoupdate` suggested, and then `src/auto/configure` is regenerated by running cd src make AUTOCONF=autoconf2.71 autoconf closes: #12958 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Illia Bobyr <illia.bobyr@gmail.com>
