I encountered with an error"error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘typedef’" when I installed zklua on ubuntu.

```
I sloved the error at last.
In file zklua.c, line 28, there is a character "_",  I delete it,and installed it successful.
I want to know the "_" is useful in others platform, maybe you should delete "_" in zklua.c.
