+       doc: %initial-action to initialize yylloc.
+       Reported by Bill Allombert.

+       yylloc.

+

+
+       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.

+
+       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.

+       maint: update for gnulib's recent update-copyright changes
+       * gnulib: Update.
+       * .x-update-copyright (COPYING): Add as it's no longer implied
+       when .x-update-copyright is present.
+       * cfg.mk (update-copyright-local): Remove, now ignored.
+       (update-copyright): Declare update-b4-copyright as a dependency.
