> There's a problematic type cast in generated c_glib service code that treat the sign bit of gint8 as normal bit (i.e. 128).
> The problem is illustrated as follows.
> {code}
> int i = 0;
> users_handler_func((*gint8)&i);  // Suppose this function tries to set i to -100
> store_handler_result(i);         // This stores 156, not -100
> {code}
