Code compiled fine under 2.8.1 but fails to compile under 2.95.1

[Thomas A Peterson <tap at htc dot honeywell dot com>]

We have some code that compiled fine under 2.8.1 but fails to compile
successfully under 2.95.1. I have included a sample of code below that
exhibits the problem.

If you replace the destructor with a different member (say a function named
fred), then there is no compiler error.  The error is not dependent on the
destructor being virtual.  The engineer who developed the code looked at (a
reasonably recent draft of) the ANSI C++ standard, and could find no
restriction on declaration of out of line functions in a template class.

CODE
----

// Start fo foo.cpp

typedef int KeyValueTYP;
class BalancedTreeBase
{
protected:
  BalancedTreeBase( KeyValueTYP _key );
  virtual ~BalancedTreeBase() { }
private:
  BalancedTreeBase();
};

template <class T>
class BalancedTreeNode : private BalancedTreeBase
{
public:
  BalancedTreeNode( KeyValueTYP _key ) : BalancedTreeBase( _key ) { }
  virtual ~BalancedTreeNode();
};

class Name;
typedef BalancedTreeNode<Name>            NameTreeNode;
// Adding this forward declaration eliminates the error.
//BalancedTreeNode<Name>::~BalancedTreeNode();

class Name 
{
public:
  Name( KeyValueTYP numericName) : aliasNamespaceNode( numericName) { }
  ~Name() { }
private:
  NameTreeNode              aliasNamespaceNode;
};

// Commenting out class Name, and declaring foo doesn't generate the error.
//NameTreeNode foo(37);

BalancedTreeNode<Name>::~BalancedTreeNode()
{
}

// end of foo.cpp
