So I made tests on trivial programs with GCC 4.3.2, and it turns out
that when you do
struct B : A
{
};
the inheritance is public, regardless of whether A is a struct or a class.
So it doesn't matter in our case that WithAlignedOperatorNew is a
struct; what matters is that ei_with_aligned_operator_new is.
I update the unalignedassert webpage because the users may use classes
not structs...
Cheers,
Benoit
