Hello, just notifying you about two changes in the Autotools build system targeted for PHP 8.6. Updating the minimum required Autoconf from 2.68 to 2.71: https://github.com/php/php-src/pull/21159 Updating the bundled Libtool to current version 2.5.4 (or if there will be stable 2.6.0 in the very near future): https://github.com/php/php-src/pull/21067

I'm bumping this topic again just in case it got lost back then as there were some issues with the mailing list. The libtool update has been merged to master branch for the upcoming PHP-8.6 and the Autoconf update is just around the corner of being merged. More info in the pull requests.
