+
+	* 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.
+	(symbol_list_n_type_name_get): Use symbol_list_n_get.
+	* src/scan-gram.l (handle_action_dollar): Flag used symbols.
+	* src/reader.c (grammar_current_rule_check): Check that values are
+	used.
+	* src/symtab.c (symbol_print): Accept 0.
+	* tests/existing.at: Remove the type information.
+	Empty the actions.
+	Remove useless actions (beware of mid-rule actions: perl -000
+	-pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
+	* tests/actions.at (Exotic Dollars): Use unused values.
+	* tests/calc.at: Likewise.
+	* tests/glr-regression.at (No users destructors if stack 0 deleted):
+	Likewise.
+
+	* src/gram.c (rule_useful_p, rule_never_reduced_p): Use
+	rule_useful_p.
+
+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.
+	* data/glr.cc: Likewise.
+	* data/lalr1.cc: Likewise.
+	* data/location.cc: Likewise.
+	* data/yacc.c: Likewise.
+
+	* NEWS: Reword %destructor vs YYABORT etc.
+	* data/glr.c: Use American spacing, for consistency.
+	* data/glr.cc: Likewise.
+	* data/lalr1.cc: Likewise.
+	* data/yacc.c: Likewise.
+	* data/yacc.c: Reformat comments slightly.
+	* doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
+	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.
+	(b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
+	yylvalp and yyllocp to &yylval and &yylloc.
+	(nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
+	namespace. Previously, nerrs and char were missing, but lval and lloc
+	weren't necessary.
+	(yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
+	yylvalp and yyllocp parameters since, if pure, these are now always
+	accessible through yystackp.  If not pure, they are still accessible
+	globally.
+	* data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
+	`if (YYID (N))' to pacify lint.
