+ 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/local.mk (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.
+
+2009-07-31 Alex Rozenman <rozenman@gmail.com>
+
+ Fix --enable-gcc-warnings problems.
+ * src/reader.c: Adjust variable names.
+ * src/scan-code.l: Fix prototypes and adjust names.
+ * src/named-ref.c: Remove redundant "if".
+
+2009-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix a --enable-gcc-warnings problem.
+ * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
+ variable.
+
+2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Warn about character literals not of length one.
+ * NEWS (2.5): Document.
+ * src/scan-gram.l (INITIAL): Remove comment that we don't check
+ the length.
+ (SC_ESCAPED_CHARACTER): Warn if length is wrong.
+ * tests/input.at (Bad character literals): New test group.
+
+2009-07-24 Alex Rozenman <rozenman@gmail.com>
+
+ Fix some memory leaks.
+ * src/named-ref.c: Add a pointer check (named_ref_free).
+ * src/scan-code.l: New function (variant_table_free). Called in
+ code_scanner_free.
+ * src/symlist.c: Call to named_ref_free (symbol_list_free).
+
+2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/lalr.c (state_lookahead_tokens_count): Correct comment.
+
+2009-07-22 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Some M4 cleanup in the testsuite.
+ Suggested by Eric Blake at
+ <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
+ * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
+ complicate the code by distinguishing between a missing value
+ and an empty string value for an optional argument. This fix is
+ allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
+ * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
+ (AT_TEST_TABLES_AND_PARSE): ... this now that the special
+ arguments are not needed because of the following changes.
+ Fix stale comments.
+ Bison developers should use GNU M4 and should not use
+ POSIXLY_CORRECT when building the test suite, so do not
+ complicate the code by avoiding $10 and above.
+ Do not quote an empty string value for an optional argument, and
+ do not distinguish between a missing value and an empty string
+ value.
+
+2009-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Revert unnecessary column realignment in --help output.
+ Reported by Akim Demaille at

+ * src/getargs.c (usage): Here.
+
+2009-07-04 Alex Rozenman <rozenman@gmail.com>
+
+ Alphabetical order in src/local.mk.
+ * src/local.mk: Adjust.

+
+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.
+
+2009-06-29 Akim Demaille <demaille@gostai.com>
+
+ parse.error: fix.
+ * data/bison.m4: Move code related to specific variables after the
+ definition of the variable-maintaining macros so that we don't
+ "invoke" b4_percent_define_check_values before it is defined.
+
+2009-06-29 Akim Demaille <demaille@gostai.com>
+
+ variables: parse.error
+
+ Implement, document, and test the replacement of %error-verbose
+ by %define parse.error "verbose".

+ values of the parse.error variable.
+ Make "simple" its default value.

+ Support it.
+ * src/scan-gram.l: Support %error-verbose.

+ * tests/actions.at, tests/calc.at: Use parse.error instead of
+ %error-verbose.
+
+2009-06-27 Alex Rozenman <rozenman@gmail.com>
+

+ * src/reader.c: Store named refs in symbol lists.
+ * src/reader.h: New argument for symbol_append and
+ action_append functions.
+ * src/scan-code.h: Add new field (named_ref) into

+ actions.
+ * src/scan-code.l: Support for named refs in semantic
+ action code. New function 'parse_named_ref'.
+ * src/scan-gram.l: Support bracketed id.
+ * src/symlist.c: Store named refs in symbol lists.
+ * src/symlist.h: New field in symbol list: named_ref.
+ * src/named-ref.h: New file, a struct for named_ref.
+ * src/named-ref.cp: New file, named_ref_new function.
+ * src/local.mk: Add two new files.
+ * tests/testsuite.at: Include new test group:
+ * tests/named-refs.at: this new file.
+

+ New.
+ (b4_percent_define_use): New.
+ Use it where applicable.
+ * data/c++.m4: Replace uses of the variable "namespace" by
+ "api.namespace".
+ Default the latter to the former.
+ * doc/bison.texinfo (Decl Summary): Document "namespace" as
+ obsolete.
+ Document api.namespace.
+ Use @samp to document %define uses, keep @code for identifiers.
+ * NEWS: Likewise.
