* NEWS: Remove notice of yytname change, since it was never in an official release. * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing diagnostic. * src/output.c (prepare): Likewise. * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro. (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE is not defined. This is an awful hack, but it's enough for now. All callers changed. * tests/glr-regression-at (make_value): Args are const pointers now, to avoid GCC warning. (Duplicated user destructor for lookahead): New test. Currently skipped. It fails on my host but I'm not sure it'll always fail.
