System: Linux jsberg1 2.4.9 #2 SMP Tue Aug 21 17:36:52 EDT 2001 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.0.2/configure --prefix=/opt/gcc-3.0.2
>Description:
	
This code:

template<class C> class S {
public:
  S();
private:
};

class T {
  friend S<int>::S<int>();
public:
  T();
private:
  void f() const;
};

template<class C> S<C>::S() {
  // T t; t.f();
}

S<int> s;

Compiled with this command line:

c++ -c test02.cxx

Gives this error

test02.cxx:8: no `void S<int>::S()' member function declared in class `S<int>'


>How-To-Repeat:
	
>Fix:
	Plenty of workarounds:
	friend class S<int>;
	or
	template<class C> friend S<C>::S();
