cannot bootstrap bison from git

[Bruno Haible]

Hi,

I'm trying to bootstrap bison from its git repository (in order to test the
Solaris make fix), as explained in README-hacking.
  ./configure
  make
  make check
works, but
  make distcheck
fails in a TEXI2DVI invocation.

Here are the details:

$ make doc/bison.dvi V=1

? 

My texi2dvi is version 6.6.

I don't have a file txi-en.tex on my disk. A web search reveals that it is
available at
  ftp://ftp.dante.de/tex-archive/macros/texinfo/texinfo/doc/txi-en.tex
and storing this file in doc/ indeed makes "make doc/bison.dvi" and
"make doc/bison.pdf" work fine.

The question is: How should txi-en.tex be distributed?
  - Do you want to mention the requirement to do
      wget -o doc/txi-en.tex 
ftp://ftp.dante.de/tex-archive/macros/texinfo/texinfo/doc/txi-en.tex
    in README-hacking?
  - Do you want to make 'bootstrap' execute this command?
  - Should txi-en.tex be distributed through gnulib, like texinfo.tex?
