Gnus/5.0808 (Gnus v5.8.8) XEmacs/21.4 (Honest Recruiter) |
| In LilyPond's parser.yy we have:
|
| #define YYPARSE_PARAM my_lily_parser
| #define YYLEX_PARAM my_lily_parser
|
| extern My_lily_parser * current_parser;
|
| int
| yylex (YYSTYPE *s, void * v)
| {
| My_lily_parser *pars = (My_lily_parser*) v;
| My_lily_lexer * lex = pars->lexer_;
|
| lex->lexval = (void*) s;
| lex->prepare_for_next_token();
| return lex->yylex ();
| }
|
| Which works with bison <= 1.35, but doesn't with 1.50a. Has anything
| changed wrt this? If it doesn't ring a bell, I'll investigate some
| further tomorrow or on Monday.
|
| Thanks.
| Greetings,

Actually what you probably hid is that yyerror is #defined. This will
be fixed in the forthcoming release. Thanks!
