Hi!  I'm a long-time user of g++ and of the g++ template system.  I was
quite surprised to find my template code responsible for many error
messages when I upgraded from gcc 2.2 to 2.3.3 (running on a Sun4
under SunOS 4.1.3).  I'm confident that the errors result from some
simple language spec change between the two versions of the compiler,
and I'm hoping to be able to modify my code accordingly.  I've
condensed the problem down to a minimal example.   

The problem concerns a report that there is no constructor present for
a template class in the visible scope.  It seems to occur when trying
to pass instances of the template class being complained about.
Here's the code:





template<class Contents> class A 
{
 public:
 A() {}
 A(A &t) {}
    
};


void    bar(A<int>);

int foo()
{
  A<int> foo;

  bar(foo);
 }



and here's the associatd compile
