+ 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.
