+       * data/glr.c (YYRHSLOC): Don't have two definitions, one for
+       the normal case and one for the error case.  Just use the
+       first one uniformly.  Problem reported by Frank Heckenbach.
+       (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
+       use exactly the same macro in both places.
+       (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
+       so that the normal-case YYRHSLOC works for the error case too.
+       All uses changed.
+       * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
+       (YYLLOC_DEFAULT): Use the same macro as glr.c.
+       * doc/bison.texinfo (Location Default Action): Don't claim that
+       we have an array of locations.  Use the same macro for both glr
+       and lalr parsers.  Mention YYRHSLOC.  Mention what happens when
+       the index is 0.
