+ * doc/bison.texinfo: here.
+
+2009-09-13 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: clean up push.at test group titles.
+ * tests/push.at: Remove "Push Parsing: " from test group titles

+
+ * NEWS (2.4.2): Add "Internationalization" item.

+ Avoid compiler warning.
+
+2009-08-27 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: use perl for printing special sequences to files.
+ And skip tests if perl is not available. This is better than
+ playing tricks with shell portability. Suggested by Akim
+ Demaille.
+ * tests/input.at (Bad character literals): Use it here for
+ omitting final newlines.
+ (Bad escapes in literals): Use it here for special characters.
+
+2009-08-21 Joel E. Denny <jdenny@clemson.edu>
+
+ Use locale when quoting.
+ * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
+ quote rather than implementing quoting here.
+
+2009-08-20 Eric Blake <ebb9@byu.net>
+
+ Make previous patch more robust.
+ * src/output.c (ARRAY_CARDINALITY): New macro, copied from
+ argmatch.h.
+ (output_skeleton): Use it.
+ Suggested by Akim Demaille.
+
+ Import latest m4/m4.m4.

+
+2009-08-19 Joel E. Denny <jdenny@clemson.edu>
+
+ Fix complaints about escape sequences.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
+ * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
+ For a \0 and similar escape sequences meaning the null
+ character, report an invalid escape sequence instead of an
+ invalid null character because the latter does not actually
+ appear in the user's input.
+ In all escape sequence complaints, don't escape the initial
+ backslash, and don't quote when the sequence appears at the end
+ of the complaint line unless there's whitespace that quotearg
+ won't escape.
+ Consistently say "invalid" not "unrecognized".
+ * tests/input.at (Bad escapes in literals): New.
+
+2009-08-19 Akim Demaille <demaille@gostai.com>
+
+ doc: %initial-action to initialize yylloc.

+ (Location Type): Document the use of %initial-action to initialize
+ yylloc.
+

+
+ maint: update for gnulib's recent update-copyright changes
+ * gnulib: Update.
+ * .x-update-copyright (COPYING): Add as it's no longer implied
+ when .x-update-copyright is present.
+ * cfg.mk (update-copyright-local): Remove, now ignored.
+ (update-copyright): Declare update-b4-copyright as a dependency.
+
+2009-08-17 Akim Demaille <demaille@gostai.com>
+
+ build: lower gettext requirements.
+
+ Bison was uselessly requiring the formatstring macros from
+ gettext, which resulted in mo files not being installed on systems
+ that perfectly supported Bison mo files. Lower the requirement.
+ http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
+
+ * configure.ac: Require need-ngettext instead of
+ need-formatstring-macros.
+ Reported by Martin Jabocs.
+ Suggested by Bruno Haible.
+ * INSTALL: Restructure.
+ (Internationalization): New.
+
+2009-08-14 Joel E. Denny <jdenny@clemson.edu>
+

+ * gnulib: Update.
+ * bootstrap.conf (gnulib_modules): Update getopt to getopt-gnu
+ as now recommended in gnulib/NEWS.

+ * cfg.mk (update-copyright-env): Configure update-copyright.
+
+2009-08-12 Akim Demaille <demaille@gostai.com>
+
+ distcheck: fix.

+ * examples/calc++/Makefile.am: (EXTRA_DIST): Ship calc.stamp.
+
+2009-08-06 Joel E. Denny <jdenny@clemson.edu>
+
+ maint: run "make update-copyright"
+ But first...
+ * .x-update-copyright (^data/m4sugar/): Add, because these
+ files are from Autoconf.
+
+2009-08-06 Joel E. Denny <jdenny@clemson.edu>
+
+ maint: make update-b4-copyright easier to use
+ * build-aux/update-b4-copyright: In warnings, report line
+ numbers rather than character positions.
+ * cfg.mk (update-copyright-local): Set to update-b4-copyright so
+ that update-copyright runs it.
+ * gnulib: Update.
+
+2009-08-05 Joel E. Denny <jdenny@clemson.edu>
+
+ maint: clean up update-b4-copyright code
+ * build-aux/update-b4-copyright: Do not accept 2-digit
+ UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
+ Don't accept a `[' in a b4_copyright argument.
+ Format code more consistently.
+ Don't assume b4*copyright never occurs.
+
+2009-08-04 Joel E. Denny <jdenny@clemson.edu>
+
+ maint: automate b4_copyright updates.
+ * Makefile.am (update-b4-copyright): New target rule.
+ * build-aux/Makefile.am (EXTRA_DIST): Add update-b4-copyright.
+ * build-aux/update-b4-copyright: New.
+ * data/yacc.c: Remove stray characters around b4_copyright
+ invocations.
+
+2009-08-04 Joel E. Denny <jdenny@clemson.edu>
+
+ maint: automate annual package-wide copyright-year update.
+ * .x-update-copyright: New.
+ * Makefile.am (EXTRA_DIST): Remove maint.mk.
+ * bootstrap.conf (gnulib_modules): Add maintainer-makefile and
+ update-copyright. Remove gnumakefile, which is implied by
+ maintainer-makefile.
+ * cfg.mk (bootstrap-tools): Copy from old maint.mk.
+ * gnulib: Update.
+ * maint.mk: Remove, now copied from gnulib.
+ * examples/extexi: Add missing "(C)" in copyright statement so
+ update-copyright can recognize it.
+ * src/LR0.h: Likewise.
+ * src/print.h: Likewise.
+ * src/print_graph.h: Likewise.
+ * src/gram.c: Add missing comma in copyright statement.
+ * src/gram.h: Likewise.
+
+2009-08-04 Joel E. Denny <jdenny@clemson.edu>
+
+ Fix "make distcheck".
+ * examples/calc++/Makefile.am: Say $(srcdir)/calc.stamp instead
+ of just calc.stamp.
+
+2009-08-01 Joel E. Denny <jdenny@clemson.edu>
+
+ Pacify "gcc -Wunused" for the input function from Flex.
+ Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
+ and later.
+ * src/scan-code.l: Add "%option noinput", which I cannot find in
+ the Flex manual, but which Flex has supported since at least as
+ far back as 2.5.4. However, if any of our developers still use
+ Flex 2.5.4, they'll need to stop configuring with
+ --enable-gcc-warnings because "%option noinput" didn't work
+ correctly until Flex 2.5.6.
+ * src/scan-gram.l: Likewise.
+ * src/scan-skel.l: Likewise.
+
+2009-06-29 Akim Demaille <demaille@gostai.com>
+
+ build: avoid concurrent extraction of calc++.
+ * examples/calc++/Makefile.am (calc.stamp): New.
+ Depend on it to create the sources of calc++ so that concurrent
+ builds don't launch several "extexi" in parallel.
+ Not only this is inefficient, this also builds incorrect sources
+ with several extractions mixed together.
+
+2009-06-25 Akim Demaille <demaille@gostai.com>
+
+ hash: check insertion for memory exhaustion.
+ * src/uniqstr.c (uniqstr_new): New.
+
+2009-06-11 Akim Demaille <demaille@gostai.com>
+
+ hash: check insertion for memory exhaustion.
+ * src/muscle-tab.c (muscle_insert, muscle_grow)
+ * src/state.c (state_hash_insert): Check the return value of
+ hash_insert.
+
+2009-06-10 Akim Demaille <demaille@gostai.com>
+
+ gnulib: update.
+ * gnulib: Update to latest.
+ * lib/.cvsignore, lib/.gitignore, m4/.cvsignore,
+ * m4/.gitignore: Regen.
+ * src/symtab.c (symbol_from_uniqstr, semantic_type_from_uniqstr):
+ Call xalloc_die on hash_insert failures.
+ Requested by the new __warn_unused_result__ attribute of
+ hash_insert.
+
+2009-05-22 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/c++.m4: Update copyright year.
+
+2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Handle a trailing `:' in a user-supplied C++ namespace better.
+ * data/c++.m4 (b4_namespace_close): Don't let it be printed
+ among the closing braces here. This fix might make the
+ generated code easier to debug, but otherwise it should be
+ insignificant because a trailing `:' is a C++ error already.
+
+2009-05-11 Akim Demaille <demaille@gostai.com>
+
+ doc: use C++ headers.
+ * doc/bison.texinfo (Calc++ Scanner): Prefer C++ headers to C
+ headers.
+
+2009-05-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Declare %code to be a permanent feature.
+ * NEWS (2.4.2): Here.
+ * doc/bison.texinfo (Prologue Alternatives): Don't say it's
+ experimental.
+ (Decl Summary): Likewise.
+
+2009-04-14 Akim Demaille <demaille@gostai.com>
+
+ doc: minor fixes.
+ * doc/bison.texinfo (Decl Summary): Fix entry about %debug.
+ (Table of Symbols): Remove duplicate entry for %debug.
+
+2009-04-06 Eric Blake <ebb9@byu.net>
+
+ Work around autoconf 2.63b bug in testsuite.
+ * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Avoid tripping
+ autoconf bug related to # in test.
+
+2009-04-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix options documentation.
+ * build-aux/cross-options.pl: As in --help output, write optional
+ arguments as [=ARG] not =[ARG].
+ * doc/bison.texinfo (Bison Options): Add -W/--warnings argument.
+
2008-11-07 Akim Demaille <demaille@gostai.com>
Fix --help.
2006-09-15 Bob Rossi <bob@brasko.net>
+ Add support for push parsing. Based on the original work of
+ Odd Arild Olsen <oao@fibula.no>.
* data/Makefile.am (dist_pkgdata_DATA): Add push.c.
* data/c.m4 (YYPUSH): New.
(b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
+ * data/push.c: New file.
* src/getargs.c (push_parser): New var.
* src/getargs.h (push_parser): New declaration.
* src/output.c (prepare): Add macro insertion of `push_flag'.
