It appears that Gerald's patch
<http://gcc.gnu.org/ml/gcc-patches/2002-12/msg00370.html> hasn't yet been
reviewed.

This file shouldn't be in CVS as a Bison-generated file, except that the
release script adds Bison-generated files to the source directory by doing
a bootstrap and this won't work for the intl directory because that
directory doesn't get built at all on systems with GNU libintl in libc.

The normal rule for what goes in CVS remains that it should be exactly the
files not removed by "make maintainer-clean", which should be all files
needed to configure and build plus some files created by more specialised
tools (e.g. autogen) or tools with tight version dependencies, plus
generated Texinfo files for update_web_docs.
