[Bug other/126960] New: [16/17 Regression] extend.texi again causes a build failure for makeinfo 4.13 (and before)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=126960

            Bug ID: 126960
           Summary: [16/17 Regression] extend.texi again causes a build
                    failure for makeinfo 4.13 (and before)
           Product: gcc
           Version: 16.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jbeulich at suse dot com
  Target Milestone: ---

"again" because of e.g. the earlier bug 120544. As said there, Texinfo 4.7 is
supposedly sufficient. This time it is fallout from b6e894a6bf32 ("gcc/doc:
Move @anchor-s referring to top of node after their @node"):
