Portability question

[Paul Schauble]

Could people please comment on the portability of this structure?  If
it's not, why not and how does one set up a structure where one needs to
access the items both by pointer/subscript in a loop and by individual
name in inline code?

    struct x {something};
    struct x *ip;

    struct
      {
          struct x a;
          struct x b;
          struct x c;
          struct x d;
          struct x e;
      }
          index;

    y = index.a.whatever;
    z = index.c.whatever;

    ip = (struct x *)&index;
    ...
    w = ip[i].whatever;
