It may be a different problem, but even with that official build, I
see something strange.

I've attached two screenshots:
* "1.png" shows the info node "(dir)Top" versus the file "info/dir".
* "2.png" shows the info node "(emacs)Top" versus the file "info/emacs-1".

In the second case, subtitles like "Indexes (each index contains a
large menu)" or "Important General Concepts" that appear in the
"info/emacs-1" file are also shown in the info buffer.

But in the first case, the subtitles ("Emacs", "GNU Emacs Lisp",
"Emacs editing modes", ...) that appear in the "info/dir" file,
doesn't appear in the corresponding info buffer.  Why?
