+       Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
+       error recovery loops.  This patch is based on
+       <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
+       Also, augment the similarity between lalr1.cc and yacc.c.
+       Note: the locations of error recovery rules are not correct yet.
+
+       * data/lalr1.cc: Comment changes to augment the similarity between
+       lalr1.cc and yacc.c.
+       (YYERROR): Goto to yyerrorlab, not yyerrlab1.
+       (yyerrlab1): Remove, but where it used to be (now the bottom part of
+       yyerrlab), when hitting EOF, pop the whole stack here instead of
+       merely falling thru the default error handling mechanism.
+       (yyerrorlab): New label, with the old contents of YYERROR,
+       plus the following change: pop the stack of rhs corresponding
+       to the production that invoked YYERROR.  That is how Yacc
+       behaves (required by POSIX).
+       * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
+       fail.
