+       Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
+       * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
+       void, not int.
+       * tests/glr-regression.at (Badly Collapsed GLR States):
+       Likewise.
+       (Improper handling of embedded actions and dollar(-N) in GLR parsers):
+       yylex should return 0 at EOF rather than aborting.
+
        Improve tests for stack overflow in GLR parser.
        Problem reported by twlevo@xs4all.nl.
        * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
