Feature-request: Possibility of transparent unions in structs

[Martin v. Loewis]

Thanks for your bug report. Please note that, in C++, you can write

struct foo {
  int type;
  union {
    int id;
    int *data;
    char *string;
  };
};

and then access the union fields transparently. I've added a
change-request to GNATS. Please also have a look at
