struct NS_GFX nsRect {
    nscoord x, y;
    nscoord width, height;

    // Constructors
    nsRect() : x(0), y(0), width(0), height(0) {}
    nsRect(const nsRect& aRect) {*this = aRect;}
    nsRect(const nsPoint& aOrigin, const nsSize &aSize) {x = aOrigin.x; y = aOrigin.y;

This seems to be bug of compiler...
