g++ question

[James Cowan]

Hi

I am returning to some c++ programming and am puzzled by g++'s complaints
about conversion of rvalues to references.

I would expect the example below to generate a warning but not an error -
earlier version of g++ did this.

Is there a compiler flag that suppresses this problem?

class A
{
public:
 A() {}
};

class B
{
public:
 B() {}

 A returnA()
 {
 A a;

  return a;
 }
};

class C
{
public:
 C() {}

 void test()
 {
 B b;
 A &a = b.returnA();

 }
};

Test.cpp: In method `void C::test()':
Test.cpp:29: warning: initialization of non-const reference `class A &' from
