+
+ 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.
+

+ Continues Akim's work from his 2009-06-10 commits.
+ * src/reader.c (check_and_convert_grammar): Don't add any
+ symbols after the first symbols_do invocation.
+ * src/symtab.c (symbols_sorted): New static global.
+ (user_token_number_redeclaration): Update comments.
+ (symbol_from_uniqstr): If a new symbol is being created, assert
+ that symbols_sorted hasn't been allocated yet.

+
+ build: fix the generation of the documentation.
+ Some of our targets use "bison --help", but they can't depend on
+ "bison" itself (to avoid additional requirements on the user), so
+ they used to call "make src/bison" in the commands. Then
+ concurrent builds may fail: one make might be aiming one of its
+ jobs at compiling src/bison, and another job at generating the man
+ page. If the latter is faster than the former, then we have two
+ makes that concurrently try to compile src/bison.
+
+ This might also be a more convincing explanation for the failure
+ described in the patch "build: fix paths".
+
+ * Makefile.am (SUFFIXES): Initialize.
+ * build-aux/move-if-change: New, symlink to gnulib's.
+ * build-aux/local.mk: Ship it.
+ * doc/common.x: Remove, merged into...
+ * doc/bison.x: here.
+ * doc/local.mk (doc/bison.help): New.
+ ($(CROSS_OPTIONS_TEXI)): Depend on it.
+ Use src/bison.
+ (.x.1): Replace with...
+ (doc/bison.1): this explicit, simpler, target.
+ (common_dep): Remove, inlined where appropriate.
+ (SUFFIXES, PREPATH): Remove, unused.
+
+2009-08-12 Akim Demaille <demaille@gostai.com>
+
+ gnulib: improve prefixing.
+ * configure.ac (gl_PREFIXED_LIBOBJS): Don't rename it, rather,
+ change the value of...
+ (gl_LIBOBJS): this.
+ Adjust more variables.
+ * etc/prefix-gnulib-mk (prefix_assignment): Don't rename
+ gl_LIBOBJS.
+ (prefix): Also transform rules whose targets have slashes.
+ Use $prefix liberally.
+ Map @MKDIR_P@ to $(MKDIR_P).
+ Prefix directories that are mkdir'd.

+
+ build: fix paths.
+ When using $(top_builddir) inconsistently, Make (including GNU
+ Make) is sometimes confused. As a result it may want to build
+ lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
+ file, different names) concurrently, which, amusingly enough,
+ might end with:
+
+ ranlib lib/libbison.a
+ ranlib lib/libbison.a
+ make[2]: *** [lib/libbison.a] Segmentation fault
+
+ on OS X.
+
+ * doc/local.mk, src/local.mk: Do not use $(top_builddir) when not
+ needed.
+
+2009-08-12 Akim Demaille <demaille@gostai.com>
+
+ distcheck: fix.
+
+ * examples/calc++/Makefile.am: (EXTRA_DIST): Ship calc.stamp.
+
+2009-08-10 Joel E. Denny <jdenny@clemson.edu>
+
+ * tests/local.mk (TESTSUITE_AT): Add named-refs.at.
+
+2009-08-10 Joel E. Denny <jdenny@clemson.edu>
+
+ Miscellaneous code readability improvements.
+
+ * src/reader.c (reader): Move %define front-end variable
+ defaults and checking into...
+ (prepare_percent_define_front_end_variables): ... this new
+ function.
+
+ * src/scan-gram.l (INITIAL): For consistency with string
+ literals, don't store open quote on character literal. It's
+ discarded before returning anyway.
+ (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
+ Make length test more readable, and make the character stored
+ for an empty literal more obvious while consistent with the
+ previous behavior.
+
+ * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
+ USER_NUMBER_HAS_STRING_ALIAS throughout.
+ * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
+ that is repeated in symtab.h. Improve argument names to make it
+ clear which side of the symbol-string alias pair is which.
+ (symbol_check_alias_consistency): Improve local variable names
+ for the same purpose.
+ * src/symtab.h (struct symbol): Make comments about aliases
+ clearer.
+ (symbol_make_alias): Improve comments and argument name.
+ * src/output.c (token_definitions_output): Update for rename to
+ USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
+
+2009-08-08 Alex Rozenman <rozenman@gmail.com>
+
+ Convert "misleading reference" messages to warnings.
+ * src/scan-code.l: New function 'show_sub_messages', more
+ factoring.
+ * tests/named-ref.at: Adjust tests.

+
+ 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.

+
+ maint: clean up update-b4-copyright code
+ * build-aux/update-b4-copyright: Do not accept 2-digit

+ Don't accept a `[' in a b4_copyright argument.
+ Format code more consistently.
+ Don't assume b4*copyright never occurs.

+ * .x-update-copyright: New.

+ * 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.

+
+ 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.
