I did as asked, but now we need two casts:

 Input_merge_map *
  get_input_merge_map(unsigned int shndx) {
    return const_cast<Input_merge_map *>(static_cast<const Object_merge_map *>(
                                             this)->get_input_merge_map(shndx));
  }

Are you sure this is better?

Cheers,
