>Description:
The following code is being rejected. 
This is a regression wrt 3.0 and 3.1.

class A {
public:
    A(){}
    A( const A& a ){}
};

class B  : public A
{
public:
  B( int& s) : s_(s){}
  int& s_;
};

int main()
{
  int i;
  B x1( i );
  B x2( x1 );
}

$ /opt/bin/g++-32 x4.cc
x4.cc: In copy constructor `B::B(const B&)':
x4.cc:18: `const' qualifiers cannot be applied to `int&'
