Upstream updated the texinfo.tex file. From the changelog file of automake 1:1.16.1-4 :
2018-03-11 Mathieu Lirzin <m...@gnu.org> maint: Update files from upstream with 'make fetch' * lib/config.guess: Update. * lib/config.sub: Likewise. * lib/gendocs.sh: Likewise. * lib/gitlog-to-changelog: Likewise. * lib/gnupload: Likewise. * lib/texinfo.tex: Likewise. * lib/update-copyright: Likewise. So the texinfo.tex file is no longer outdated. But I could check that automake still installs the version it distributes, which could yield a similar issue in the future (having different versions in makeinfo and automake may also bring confusion). I also think that this bug could be merged with bug 882844, which is about the same issue. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
