Just so that you know, I asked the texinfo help list and it appears that the texinfo.tex file that I had was not good (although that's the one I checked out from the git repository).

Karl told me I should use the one on the ftp.gnu.org site, which I did, and all the missing index reappeared.

So there is maybe an issue with the emacs git repository file.

I just did a new checkout on emacs master, removed/reinstalled texinfo. But I have the same result.
There must be something trivial that I'm missing... :(

Looks like some problem with Texinfo you are installing, or with TeX
(a separate package), or maybe with Gawk (nowadays texindex is an Awk
script).

Ok, I'll check all that. But considering that I've recently had errors with the libxml2 headers when building emacs all this is probably strongly related.

I've reinstalled the whole mactex distribution and I still get the same result...

Still investigating...
