I'm not holding this against the patch too much because it's ddraw,
but I think "if (flags & D3DLIGHT_NO_SPECULAR)" and then flipping the
branches reads a bit nicer. If the declaration of "zero_value" is
fixed you can avoid the cast as well.

There's something to be said for "sizeof(D3DLIGHT)" here, although I
don't think "sizeof(*data)" would have been worse.
