its easy, e.g you want a special driver struct for a racing game, you could do it with this:
Code:
typedef struct DRIVER {
char name; //driver name
VECTOR position;
VECTOR angle
double mass;
int rank;
} DRIVER;
I dont know when its out, because its currently under development and beta testing.. so I guess "when its ready"

Though, send JCL an email with your qualifications to become a betatester - by this you are allowed to use the current liteC compiler.
