Description Paolo Carlini 2005-04-26 11:49:22 UTC 
The below doesn't compile with 4.0:

class KopeteAwayDialog { KopeteAwayDialog(); };
namespace Kopete
{
  class Away
  {
    friend class KopeteAwayDialog;
  };
}
using namespace Kopete;
KopeteAwayDialog::KopeteAwayDialog(){}

novell78625.cc:10: error: 'KopeteAwayDialog' has not been declared
novell78625.cc:10: error: ISO C++ forbids declaration of 'KopeteAwayDialog' with
no type

This is a regression from 3.3/3.4. Current mainline is ok, however, most
probably due to these patches from Kriang:

Note 3.x did not friend the right class, it should have friended Kopete::KopeteAwayDialog but instead 
friends ::KopeteAwayDialog.  In 4.0.0 we friend the wrong class bug declare the class which is where 
the problem comes from.  In 4.1.0 we do correct thing in that we friend the correct class and now the 
new class is not declared.

Anyways this is a dup of bug 19403.
