   I found a problem.

   This is the declaration of gl_list_iterator_t,

   typedef struct
   {
     /* For fast dispatch of gl_list_iterator_next.  */
     const struct gl_list_implementation *vtable;
     /* For detecting whether the last returned element was removed.  */
     gl_list_t list;
     size_t count;
     /* Other, implementation-private fields.  */
     void *p; void *q;
     size_t i; size_t j;
   } gl_list_iterator_t;


   I think we can't convert that to (void*).
   One solution would be to paste that right on pdf-list.h but it's not an
   alternative, since we won't gain anything after all if we mix detailed
   structures with (void*) pointer structures.

   I'm stuck here.

What is the problem? You can cast a void* pointer to a
gl_list_iterator_t* pointer. Am I missing something?
