well, I guess we'll have to agree to disagree, I've read a couple of
things that say it should be OK, but the other things indicate
otherwise...

class X
{
};

class Y
{
  Y(X &X) {}
};

class Z
{
  friend class F;
  Z(F &F) {}
};

class F
{
};

class Z2
{
  friend class F2;
  Z2(F2 &f) {}
};

class F2
{
};

class F3;

class Z3
{
  friend class F3;
  Z3(F3 &f) {}
};

class F3
{
};

I think the CVS at line 59 has a typo...

ImageChannel(Image &Image)
                    ^i
but it still won't make a difference.

P.S. Hope this is taken in the spirit intended :-)
