The error is:

foo.cc:5: ANSI C++ forbids initialization of member `next'
foo.cc:5: making `next' static
foo.cc:5: ANSI C++ forbids in-class initialization of non-const static member `next'

So you can't initialize it like that.  Understandable, since it would
have to be done for every instance of BADGUY, many of which are
created on the fly.  The correct way, I believe, is to write a
constructor which does this initialization.

You can't return an array.  You must instead return a pointer.  Note
that the pointer can *point* to the array.  Example:

char *foo(void)
{
  static char str[] = "Hello world";
  return str;
}

Any good book on C++ should explain this.

Also note the static; be careful never to return pointers to auto
variables, since they disappear when the function returns!
