(?.?): ... 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.

storage that was freed from the stack).
(xml_escape_n): Don't bother checking for subscript error.

when the calls are not intended to be translated.

(scan_skel): Remove decl, since scan-skel.h does this.
(output_skeleton):
Indent calls to "error" to pacify "make maintainer-distcheck".
* src/print_graph.c: Don't include <obstack.h>, as system.h does this.

"make maintainer-distcheck" complained about.
location that is not defined. This results in garbage, and that
affects Bison's own parser. Therefore we need (i) to extend Bison
to support a means to initialize this location, and (ii) to use
this CVS Bison to fix CVS Bison's parser.

with...
* src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.

stricter %token grammar.

action member.
Adjust callers.
(output_skeleton): Don't look for the skeleton location, let m4 do
that.
Create `/tmp/muscles.m4'. This is temporary, a proper temporary
file will be used.
Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
(prepare): Given that for the time being changesyntax is not
usable in M4, rename the muscles using `-' to `_'.
Define `defines_flag', `output_parser_name' and `output_header_name'.
* src/output.h (actions_output, guards_output)
(token_definitions_output): Adjust prototypes.

to date.
* tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
* data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
shamelessly stolen from CVS Autoconf.
* src/Makefile.am: Add parse-skel.c and scan-skel.c to BUILT_SOURCES, to ensure they are generated first.

(MUSCLE_INSERT_PREFIX): ...to there.
* src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
(MUSCLE_INSERT_PREFIX): Move from here...
* src/bison.hairy: Add a section directive. Put braces around muscle
names. This parser skeleton is still broken, but Bison should not
choke on a bad muscle 'syntax'.
* src/bison.simple: Add a section directive. Put braces around muscle
names.
* src/files.h (strsuffix, stringappend): Add declarations.
(tab_extension): Add declaration.
(short_base_name): Add declaration.
* src/files.c (strsuffix, stringappend): No longer static. These
functions are used in the skeleton parser.

to guess if the generated parsers should have '.tab' in their
names.
(short_base_name): No longer static.
* src/output.c (output_skeleton): New.
(output): Disable call to output_master_parser, and give a try to
a new skeleton handling system.

* src/conflicts, src/lalr.c, src/output.c, src/print.c,
* src/print_graph: Adjust.
(CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
Gettext doesn't compile cleanly, and dies with -Werror.
* src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
Include WARNING_CFLAGS here.

before being defined.
