+       * 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++.
+

+
+       * 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.

+
+       * 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.
+

+
+       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.
