[Bug c++/28820] sizeof == 0 for empty class

class A
{
public:
        int a[0];
};


This class is not empty, it contains a (GNU) variable sized array so the size
of zero is correct for this extension.  The reason why it is zero is because
the array size is zero, this allows for the correct caculation when doing
sizeof(A)+sizeof(int)*n for malloc and/or new.
