Package: emacs
Version: 25.0.94

Trying to make the pdf versions of the manuals on RHEL 7.2 fails for
some of them (lispintro, bovine, semantic, srecode, tramp, wisent).
It works if one uses the texinfo.tex from emacs-24. (I have often
wondered if commits like 9c2a1a264cf418 are a good idea during
pretesting.)

The errors are of the form:

This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013)

[...]

Reverting to the previous texinfo.tex does fix the bug, so I did that. 
I'll send a bug report to Karl Berry about the texinfo.tex bug.

As I understand it, changes to texinfo.tex are fair game since it's just 
documentation. At this point, though, it may be wise to stop updating 
texinfo.tex from Gnulib unless the update fixes a known bug in the Emacs 
documentation and does not cause problems like this one.
