So you did find a real bug.  But maybe it's gone in more recent
version of Bison.

Yep, GNU was attacked, and to make things worse, my ISP is bankrupt,
hence I have a miserable service: I'm not even sure I can upload the
tarball somewhere :(  Maybe you can try:

        http://goa.lrde.epita.fr/~akim/download/bison-1.49b.tar.bz2

but I wouldn't be surprised if it failed.

If you're brace enough, follow this file:

These notes intend to help people working on the CVS versions of
Bison.

* Requirements

Only the sources are installed in the CVS repository (to ease the
maintenance, merges etc.), therefore you will have to the maintainer
tools we depend upon:

- Automake 1.6.2

- Autoconf 2.53b
  (ftp://sources.redhat.com/pub/automake/autoconf-2.53b.tar.gz)

- Gettext 0.11.3

Only building the initial full source tree will be a bit painful,
later, a plain `cvs update -P & make' should be sufficient.

* First CVS checkout

Obviously, if you are reading these notes, you did manage to check out
Bison from CVS.  For the records, you will find all the relevant
information on:

        http://savannah.gnu.org/cvs/?group_id=56

The next step is asking the installation of all the missing files:

        $ ./bootstrap

And there you are!  Just

        $ ./configure && make && make check

At this point, there should be no difference between your local copy,
and the CVS master copy:

        $ cvs diff

should output no difference, except maybe the date in po/*.po files.

Enjoy!

* Troubleshooting

Unfortunately the current Gettext still does not include all the
needed tools so that the bootstrapping always perform successfully.

If you experiment problems, I suggest the following:

1. Do a regular CVS checkout

2. Fetch a recent tarball.
   http://www.lrde.epita.fr/~akim/download/bison-1.49b.tar.gz

3. Extract it

4. Override the content of your checkout with the content of this
   tarball, i.e.:
   cp -r bison-1.49b/* bison-cvs

5. Proceed on ./configure && make etc.

That would be terrific!
