You can see that some nodes appear to be inaccessible in the file at
the link you sent.  Everything from "make -k Status" onwards is
inaccessible, including the index nodes.

This is very likely an issue with Tags Table at the end of the file.

I downloaded autoconf.texi and associated files from gnu.org and rebuilt
with a development version of texi2any and I didn't reproduce the problem.

I downloaded autoconf-2.71.tar.xz from ftp.gnu.org and could open the
contained autoconf.info file with no problems (it also had the curly
quotes).

Diffing this working file (with the curly quotes) with your failing
file reveals the only difference appears to be the use of "-2.71"
suffixes throughout the file.  I am attaching the result of

diff autoconf-2.71/doc/autoconf.info autoconf-2.71.info
 
Is there any chance than any Gentoo build process has modified the files
to add this string in?  This is incorrect as it makes Tag Table offsets
incorrect.
