+
+ Suppress signed/unsigned comparison warnings for yycheck.
+ * data/c.m4 (b4_safest_int_type): New macro.
+ * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
+ a signed int type, cast it to b4_safest_int_type first.
+ * data/yacc.c: Likewise.
+ (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
+ also overwritten.
+
+2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
+
+ * doc/bison.texinfo: Fix some typos.
+
+2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
+ po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
+
+ * bootstrap (gnulib_tool): Stop using --assume-autoconf;
+ the latest gnulib does this a different way.
+ (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
+ translation was patched, so stop omitting it.

+
+ Enable declaration of default %printer/%destructor. Make the parser
+ use these for all user-declared grammar symbols for which the user does
+ not declare a specific %printer/%destructor. Thus, the parser uses it
+ for token 0 if the user declares it but not if Bison generates it as
+ $end. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
+ * NEWS (2.3+): Mention.
+ * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
+ declare a %destructor for a mid-rule's semantic value. It's just
+ impossible to declare one specific to it.
+ (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
+ code. Describe default %destructor form.
+ * src/parse-gram.y (grammar_declaration): Parse default
+ %printer/%destructor declarations.
+ * src/output.c (symbol_destructors_output): Use symbol_destructor_get
+ and symbol_destructor_location_get rather than accessing the destructor
+ and destructor_location members of struct symbol.
+ (symbol_printers_output): Likewise but for %printer's.
+ * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
+ again.
+ * src/symtab.c (default_destructor, default_destructor_location,
+ default_printer, default_printer_location): New static global
+ variables to record the default %destructor and %printer.
+ (symbol_destructor_get, symbol_destructor_location_get,
+ symbol_printer_get, symbol_printer_location_get): New functions to
+ compute the appropriate %destructor and %printer for a symbol.
+ (default_destructor_set, default_printer_set): New functions to set the
+ default %destructor and %printer.
+ * src/symtab.h: Prototype all those new functions.
+ * tests/actions.at (Default %printer and %destructor): New test to
+ check that the right %printer and %destructor are called, that they're
+ not called for $end, and that $$ and @$ work correctly.
+ (Default %printer and %destructor for user-declared end token): New
+ test to check that the default %printer and %destructor are called for
+ a user-declared end token.
+ * tests/input.at (Default %printer and %destructor redeclared, Unused
+ values with default %destructor): New tests to check related grammar
+ warnings and errors.
+
+2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up handling of %destructor for the end token (token 0).
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
+ and
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
+
+ Make the skeletons consistent in how they pop the end token and invoke
+ its %destructor.
+ * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
+ state, which has token number 0, since this would invoke the
+ %destructor for the end token.
+ * data/lalr1.cc (yy::parser::parse): Don't check for the final state
+ until after shifting the end token, or else it won't be popped.
+ * data/yacc.c (yyparse): Likewise.
+
+ * data/glr.c (yyparse): Clear the lookahead after shifting it even when
+ it's the end token. Upon termination, destroy an unshifted lookahead
+ even when it's the end token.
+ * data/lalr1.cc (yy::parser::parse): Likewise.
+ * data/yacc.c (yyparse): Likewise.
+
+ * src/reader.c (packgram): Don't check rule 0. This suppresses unused
+ value warnings for the end token when the user gives the end token a
+ %destructor.
+
+ * tests/actions.at (Printers and Destructors): Test all the above.
+
+2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Update to latest gnulib and gettext versions.
+ * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
+ Add fopen-safer.
+ (gnulib_files): Add m4/warning.m4. Don't worry about files
+ overwritten by autopoint.
+ Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
+ Suppress "id", "ms", "tr" translations for now, since gettext 0.15
+ rejects them.
+ Don't use autoreconf; instead, invoke autopoint etc. by hand,
+ so that we can remove the intl files at a better time.
+ (intl_files_to_remove): Remove aclocal.m4, since it gets
+ rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
+ m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
+ m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
+ Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
+ Remove datarootdir hack; no longer needed.
+ * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
+ (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
+ * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
+ strdup.h.
+ * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
+ * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
+
+2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Adjust to today's change to gnulib-tool by invoking
+ it with --assume-autoconf='latest-stable'.
+
+2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
+ least 1.4.7 and 1.4.4) by putting a #line between `typedef union
+ YYSTYPE' and `{'.
+ * src/muscle_tab.h (muscle_grow): Replace the header comments with
+ those from muscle_tab.c since the old ones are misleading.
+
+2006-07-13 Akim Demaille <akim@epita.fr>
+
+ Support %define "KEY" {VALUE}.
+ * src/scan-code.h, src/scan-code.l (translate_action)
+ (translate_rule_action, translate_symbol_action, translate_code):
+ Return char *, not const char *.
+ * src/parse-gram.y (declaration): Rename as...
+ (prologue_declaration): this.
+ (string_content): Remove this nonterminal, use STRING.
+ (braceless, content, content.opt): New nonterminal.
+ Use them.
+ (%define): Now accept content.opt, i.e., accept also BRACED_CODE
+ as value.
+ * src/scan-gram.l (getargs.h): Don't include it.
+
+2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
+ rather than a for-loop that declares a local bool variable. This
+ should work around a compatibility problem with a Cray x1e C++
+ compiler reported by Hung Nguyen in
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
+ The for-loop was introduced in the 2004-11-17 change but I don't
+ know why it was needed.
+
+2006-07-12 Akim Demaille <akim@epita.fr>
+
+ * data/c.m4: Comment changes.
+
2006-07-10 Akim Demaille <akim@lrde.epita.fr>
* src/complain.c (error_message, ERROR_MESSAGE): New.
* data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
