Tolua problems with struct

[Simon Frost <sdfrost@...>]

Dear Lua list,

I'm trying to bind the random number generation part of the GNU scientific 
library (GSL) to Lua using tolua. All the functions seem to wrap just fine, 
but tolua (v5) chokes on gsl_rng_type with a 405:parse error, associated 
with the pointers to functions within the struct. Any ideas on how to get 
round this?

Thanks!
Simon

typedef struct
  {
    const char *name;
    unsigned long int max;
    unsigned long int min;
    int size;
    void (*set) (void *state, unsigned long int seed);
    unsigned long int (*get) (void *state);
    double (*get_double) (void *state);
  }
gsl_rng_type;

typedef struct
  {
    const gsl_rng_type * type;
    void *state;
  }
gsl_rng;
