Thank you Hans for this answer,
I know that this is the general way to do this but the lexer is in fact an
external module that I cant modify. I would like to avoid rewriting all the
token and their value in another file. If need to I will but I would to
avoid it in order to have more maintainable source code.
I just want to be sure that Bison do not support this kind of feature (Which
is actually the real purpose of my post here).
