+       * data/yacc.c (YY_LOCATION_PRINT): New.
+       Define when we know YYLTYPE's structure, i.e., when the default
+       YYLLOC_DEFAULT is used.
+       * data/c.m4 (b4_yysymprint_generate): Use it.
+       * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
+       value of the result.
+       (error_start_): Replace with...
+       (error_range_): this location array.
+       This allows to replace code relying on the implementation of
+       locations by portable code.
+       * data/yacc.c (yylerrsp): Replace with...
+       (yyerror_range): this.
+       Every time a token is popped, update yyerror_range[0], to have an
+       accurate location for the error token.
+       * data/glr.c (YY_LOCATION_PRINT): New.
+       (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
+       deference a pointer.
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
+       report the location in %printers.
+
+       * src/scan-skel.l: Instead of abort, report error messages to ease
+       understanding skeleton scanning failures.
