+
+       Change the handling of @s so that they behave exactly like $s.
+       There is now a pseudo variable @$ (readble and writable), location
+       of the lhs of the rule (by default ranging from the location of
+       the first symbol of the rhs, to the location of the last symbol,
+       or, if the rhs is empty, YYLLOC).
+
+       * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
+       yyval.
+       (yyparse): When providing a default semantic action, provide a
+       default location action.
+       (after the $): No longer change `*YYLSP', just stack YYLOC the
+       same way you stack YYVAL.
+       * src/reader.c (read_declarations): Use warns.
+       (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
+       (copy_action, case '@'): Likewise.
+       Use a standard error message, to save useless work from
+       translators.
