Most of those macros are not needed and can be just part the 
struct definition:

i.e. you want something like

struct kh_hashtable(K,V,bool _is_map, alias hash_func, alias 
hash_eq = (K a, K b)=> a == b) {
     khint_t n_buckets, size, n_occupied, upper_bound;
     khint32_t *flags;
      K *keys;
      V *vals;
     //No need for __KHASH_PROTOTYPES / __KHASH_IMPL just declare 
the function as methods of the struct
     this() { ... } // in place of kh_init_##name
     ~this() { ... } // for destroy
     resize(khint_t new_size){ ... }  //kh_resize_##name
     // and so on for each method in __KHASH_IMPL

}
