[svn r231] Changed: warnings are no longer treated as an error. Added some comments and cleaned up CallExp::toElem a tiny bit. Fixed: struct literals always reported inplace assignment even if they allocated a temporary. Fixed: passing stuff to a D-style vararg which did inplace assignment was generated suboptimal code.

module multiarr1;

void main()
{
    int[16][16] a;
    a[10][13] = 42;
    //assert(a[0][0] == 0);
    //assert(a[10][13] == 42);
    {
        int* l = cast(int*)a;
        l += 10*16+13;
        assert(*l == 42);
    }
