[Bug c++/21235] New: [4.0 Regression] Trouble with friend and using namespace

[pcarlini at suse dot de]

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:
