+       variables: simplify the upgrade of namespace into api.namespace.
+
+       This patch simplifies "variables: rename namespace as
+       api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.
+       Suggested by Joel E. Denny in
+       http://lists.gnu.org/archive/html/bison-patches/2009-07/msg00006.html
+
+       * src/muscle-tab.c (muscle_percent_variable_update): New.
+       (muscle_percent_define_insert): Use it in replacement of the
+       previous tr invocation.
+       Remove variable_tr, no longer needed.
+       * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
+       Remove.
+       * data/c++.m4: No longer handle namespace -> api.namespace.

+       Reported by Bill Allombert.

+       lalr1.cc: use state_type.
+       * data/lalr1.cc (yysyntax_error_): Use state_type.
+       Move argument names into yy*.
+
+2009-08-19  Akim Demaille  <demaille@gostai.com>
+
+       lalr1.cc: get rid of yyparse's yystate.
+       yystate and yystack_[0].state are equal, keep only the latter.
+       The former was also used as a temporary variable to compute the
+       post-reduction state.  Move this computation into an auxiliary
+       function.
+
+       * data/glr.c (yyLRgotoState): Fuse variable definition and first
+       assignment.
+       * data/lalr1.cc (yy_lr_goto_state_): New.
+       (yyparse): Use it.
+       Replace remaining uses of yystate by yystate_[0].state.
+       Remove the former.
+
+2009-08-19  Akim Demaille  <demaille@gostai.com>
+
+       lalr1.cc: destroy $$ when YYERROR is called.
+       * data/lalr1.cc (yyreduce): Compute the resulting state before
+       running the user action so that yylhs is a valid symbol.
+       (yyerrorlab): Since yylhs is complete (it knows its type), we can
+       simply call yy_destroy_ to destroy $$ on YYERROR invocations.
+       * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.
