How to raise an error

[BradDaBug]

My parser basically works by calling various functions that build a big parse
tree. Something like this:

identifier:
   LOCALIDENTIFIER { $$ = CreateIdentifierNode(yytext); }

The problem is that I need to be able to detect errors within those
functions (for example, is the identifier name too long) and propagate them
back to Bison. But I don't know how. I don't have access to the YYERROR
macro in those functions, and I can't manually "goto yyerrorlab;" since I'm
in a different function.

How can I do it?
