[svn r15] * Fixed a bunch problems with virtual calls. Seems I did some rather poor testing. * Now 50/51 tests compile. * Added a simple runalltests.d scripts that should be run with 'gdmd -run runalltests.d' - LLVMDC will not compile it yet.

class A
{
    int i;
    void f()
    {
        printf("A.f\n");
    }
}

class B : A
{
    long l;
    void f()
    {
        printf("B.f\n");
    }
}

void main()
{
    A a = new B;
    a.f();
}
