+       * 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.

+
+       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.
+
+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.

        * Makefile.am: DJGPP specific files added to EXTRA_DIST.
