oops! I see. The problem is the token_stream's next_token()

   inline int kdev_pg_token_stream::next_token() {
     return _M_token_buffer[_M_index++].kind;

see? _M_index points to the next token and not to the look-ahead.  
This is so unintuitive! I hate myself ;-) well, add a function (e.g.  
yytoken_index() or something like that) to kdev_pg_token_stream. The  
function should return `0' if _M_index is `0'  and _M_index - 1 when  
_M_index is valid.
