Why is there some C?/C++? code in that .y file?

It has the look of a production grammar with the reduction actions stripped out (but whatever they used didn't strip the %{ initializer block). I would say that, for starters, you want to strip or modify the %{ block, and possibly remove/replace the empty { } actions in the grammar.
