If you go to the top-level info node, you will see that there is no direct menu entry for the "g++" command. I think we should have one, which means adding an @direntry for it. (See gcc/java/gcj.texi for an example of per-command @direntry use)
More generally I think we should have an @direntry for each program we install in $bindir. I haven't looked to see what other ones might be missing. -- Summary: gcc.texi missing @direntry for g++ Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tromey at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25701
