I think one reason that there are (and were) that many warnings is that 
only recently texinfo gained support for diagnosing these issues. (Or 
maybe not that recent but distributions were slow in adapting newer 
texinfo versions.)

Attached is a warning-removal patch.
OK for the trunk?

Regarding invoke.texi: It had (nearly) the same @menu twice, once under 
@chapter where it belongs to and once under a @section where it doesn't.
