error: no matching function for call to `Anton::Anton(Anton)`

["e.karge" <e dot karge at struction dot de>]

The following code snippet will generate the compiler message quoted in
the subject line. However, things worked fine with gcc 2.95.3. What's the
reason for this and is there any general solution to work around this?

regards,

eric

class Anton

  public:

    Anton(Anton &a)
    {
      // some code wich _needs_ to modify a

};

int main (int, char **)

  Anton a[] = {
    Anton(),
    // ...
