[help-texinfo] error building pdf docs, everything fine with info html dvi ps

[Marco Maggi]

Ciao,

  on a  i686-pc-linux-gnu with  GNU Automake 1.12.1  and GNU
Texinfo 4.13,  I can correctly build  documentation in info,
html, dvi and ps formats, but:

  $ make pdf
  TEXINPUTS="../../doc:$TEXINPUTS" \
          MAKEINFO='/bin/sh /home/marco/src/devel/scheme/vicare/missing --run 
makeinfo -I ../../doc' \
          texi2dvi --pdf --batch --clean ../../doc/vicare.texi
  This is pdfeTeXk, Version 3.141592-1.21a-2.2 (Web2C 7.5.4)
   file:line:error style messages enabled.

  l.249 @chapter Overview of Vicare Scheme

followed by a lot of similar errors (one for each heading in
the source file, it seems).  It appears that I have the same
problems with all my texi files; for example:

<http://raw.github.com/marcomaggi/cre2/master/doc/cre2.texi>
    <http://github.com/marcomaggi/cre2/tree/master/doc>

  It  is  my   understanding  that  the  "texinfo.tex"  file
installed by Automake is the very latest from:

             <http://ftp.gnu.org/gnu/texinfo/>

  I know nothing of Texinfo internals, any hints?

TIA
