* NEWS (2.5): Add entry for LAC, and mention LAC in entry for
other corrections to verbose syntax error messages.
* doc/bison.texinfo (Decl Summary): Rewrite entries for
lr.default-reductions and lr.type to be clearer, to mention
%nonassoc's effect on canonical LR, and to mention LAC. Add entry

* bootstrap: Copy from gnulib's latest for the fix to
automatically anchor entries it constructs.
* gnulib: Update to latest just so it has the same bootstrap.
* .gitignore, build-aux/.gitignore, doc/.gitignore:
* lib/.gitignore, m4/.gitignore, po/.gitignore:
* runtime-po/.gitignore: Re-anchor all entries.

these files, they can resurrect them.
* .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
* m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
Omit leading '/', since bootstrap omits it.
Adjust file names to match current contents better.
* bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
installed just for us.
* bootstrap.conf (excluded_files): Don't exclude codeset.m4,
glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
needed somehow. Don't have time to look into why.
(gnulib_modules): Change malloc to malloc-gnu. Do we really assume
the GNU malloc behavior, where malloc (0) != NULL unless we're
out of storage? If not, we can omit malloc-gnu; but for now I left
it in to be safe.
(vc_ignore): Remove.
* README-hacking: Renamed from HACKING, since gnulib bootstrap now
uses that convention.

uses of tr so far, command-line arguments can be involved, and
getargs.h is already included.

(Option Cross Key): Implement FIXME: listing directives also.

unusual anyway.

(Doxyfile): Don't define Id, and thus don't depend on ChangeLog.

revision.

(EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
.prev-version, and .version.
* NEWS (2.3b+): Rename to...
(?.?): ... this because we're dropping the "+" version naming scheme,
but, in general, we still can't be sure of our next release name.
* bootstrap: Add a quick hack to remove from .gitignore the
GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
entry. This should really be fixed in gnulib instead.

* m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
(/setenv.m4): Add.
* src/output.c (output_skeleton): For the m4 invocation, pass -dV as
the first argument because it may become position-dependent, and unset
POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
Add comments explaining these issues in more detail.
* doc/bison.texinfo (Bison Options): Reword -W entry a little for
consistency. Update the -g and -x entries now that they take
arguments. Use brackets to indicate optional arguments.

long and short options more completely. Document --defines and -d
separately since the former takes an argument but, for POSIX Yacc, the
latter does not.

(getargs): Sort cases.
