Thank you for this quick answer ! Including the file solved the problem, it was indeed an undefined macro. By the way, sorry to be on the wrong mailing list, but unless I misunderstand the following autoconf-archive mailing lists topics, none on them is suitable for my question : * autoconf-archive-announce (Receive announcments of new releases.) * autoconf-archive-commits (E-mail notifications for the Autoconf Archive git repository.) * autoconf-archive-maintainers (Autoconf Archive Shop Talk) --- Anyway, thank you for your help and improvement recommandations.
