+
+	* src/reader.c (grammar_midrule_action, grammar_symbol_append):
+	Remove unnecessary forward static decls.
+
+2005-12-27  Akim Demaille  <akim@epita.fr>
+
+	* src/reader.c (grammar_current_rule_check): Also check that $$
+	is used.
+	Take the rule to check as argument, hence rename as...
+	(grammar_rule_check): this.
+	* src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
+	Rename as...
+	(grammar_rule_begin, grammar_rule_end): these, for consistency.
+	(grammar_midrule_action, grammar_symbol_append): Now static.
+	* tests/torture.at (input): Don't rely on the default action
+	being always performed.
+	* tests/calc.at: "Set" $$ even when the action is "cut" with
+	YYERROR or other.
+	* tests/actions.at (Exotic Dollars): Instead of using unused
+	values, check that the warning is issued.
+
+2005-12-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Improve wording for unused-value warnings.
+
+2005-12-22  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4
+	(b4_yysymprint_generate): Rename as...
+	(b4_yy_symbol_print_generate): this.
+	Generate yy_symbol_print instead of yysymprint.
+	Generate also yy_symbol_value_print, and use it.
+
+2005-12-22  Akim Demaille  <akim@epita.fr>
+
+	* NEWS: Warn about unused values.
+	* src/symlist.h, src/symlist.c (symbol_list, symbol_list_new): Add
+	a `used' member.
+	(symbol_list_n_get, symbol_list_n_used_set): New.

+	* src/reader.c (grammar_current_rule_check): Check that values are
+	used.
+	* src/symtab.c (symbol_print): Accept 0.

+
+2005-12-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Undo 2005-12-01 tentative license wording change.  The wording is
+	still being reviewed by the lawyers, and we don't want to wait for
+	them before publishing a test release.  For now, revert to the
+	previous wording.
+	* NEWS: Undo 2005-12-01 change.
+	* data/glr.c: Revert to previous license wording.

+	for consistency.  Fix some spelling errors and reword recently-included
+	text slightly.
+	* tests/cxx-type.at: Cast results of malloc, for C++.
+
+2005-12-21  Joel E. Denny  <address@hidden>
+
+	* tests/cxx-type.at: Construct a tree, count the parents of shared
+	nodes, and free each node once and only once.  Previously, the memory
+	for semantic values was leaked instead.
+
+2005-12-21  Joel E. Denny  <address@hidden>
+
+	* data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
+	(yylval, yylloc): If pure, #define to yystackp->yyval and
+	yystackp->yyloc similar to yychar and yynerrs.
+	(yyparse): If pure, remove local yylval and yylloc. Add local
+	yystackp to accommodate pure definitions of yylval and yylloc.

+	yylvalp and yyllocp to &yylval and &yylloc.

+	yylvalp and yyllocp parameters since, if pure, these are now always
+	accessible through yystackp.  If not pure, they are still accessible
+	globally.

+	`if (YYID (N))' to pacify lint.
+
+2005-12-21  Akim Demaille  <akim@epita.fr>
+
+	YYACCEPT, YYERROR, and YYABORT, as user actions, should not
+	destroy the RHS symbols of a rule.
+	* data/yacc.c (yylen): Initialize to 0.
+	Keep its value to the number of items to possibly shift.
+	In particular, a regular successful parse that ends on YYFINAL by
+	a (internal) YYACCEPT must not have yylen != 0.
+	(yyerrorlab, yyreturn): Pop the RHS.
+	Reorder a bit to emphasize the `shifting' bits of code.
+	(YYPOPSTACK): Now accept a number of items to pop.
+	* data/lalr1.cc: Likewise.
+	* data/glr.c: Formatting changes.
+	Use goto instead of fall through.
+	* doc/bison.texinfo (Destructor Decl): Complete.
+
+2005-12-20  Juan Manuel Guerrero  <juan.guerrero@gmx.de>
+
+	* Makefile.am: DJGPP specific files added to EXTRA_DIST.
+	* djgpp/Makefile.maint: Fix PACKAGE variable computation.
+	* djgpp/config.bat: Replace every occurence of the file name
+	scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
+	c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
+	* djgpp/config.sed: Replace every occurence of the file name
+	scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
+	c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
+	* djgpp/djunpack.bat: DJGPP specific file.
+	* djgpp/fnchange.lst: DJGPP specific file.
+	* djgpp/README.in: Add new information about how to unpack the bison
+	source on MSDOS and other systems which have 8.3 file name restrictions
+	using djunpack.bat and fnchange.lst.

+	consistency.
+	(yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
+	(yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
+	(yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
+	lint.
+
+2005-12-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/sets.at (Accept): Fix typos in regular expression used to
+	sed out the final state number.
+
+	Work around portability problem on Solaris 10: flex-generated
+	files include <stdio.h> before <config.h>, which messes up
+	because the latter defines __EXTENSIONS__.  Address the problem
+	by creating two new little files that include <config.h> first,
+	then include the flex-generated files.  Rewrite everyone else
+	to include <config.h> first, as well.
+	* lib/timevar.c: Always include "config.h".

+	* data/glr.c (YYUSE): Properly parenthesize, and use an alternate
+	definition if 'lint' is defined.

+	(yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
+	* data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
+	is C++ only.
+	* data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
+	* data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
+	Use YYID(0) rather than 0, for lint.
+	(yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
+	(yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
+
+2005-12-07  Paul Eggert  <eggert@cs.ucla.edu>

+
+	* NEWS: Document the following change.
+	* data/yacc.c: Say "parser skeleton" rather than "file", since
+	it's no longer just a file.

+	* data/glr.cc: Likewise.
+	* data/lalr1.cc: Likewise.
+	* data/location.cc: Likewise.
+	* data/yacc.c: Reword the "written by" statement to clarify that

+	* data/glr.c: Written by Paul Hilfinger.
+	* data/glr.cc: Written by Akim Demaille.
+	* data/lalr1.cc: Likewise.
+
+2005-11-18  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
+	Fix typos in previous change that broke 'make check'.

+
+2005-11-14  Akim Demaille  <akim@epita.fr>
+

+
+	* data/lalr1.cc: Move the body of the ctor and dtor into the
+	parser file (instead of the header).

+
+2005-11-12  Akim Demaille  <akim@epita.fr>
+
+	Have glr.c include its header file when created.
+	* data/glr.c (b4_shared_declarations): New.

+
+	* data/glr.c: Comment changes.

+
+	* data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at

+
+	Use unlocked I/O for a minor performance improvement on hosts like
+	GNU/Linux and Solaris that support unlocked I/O.  The basic idea
