Created an attachment (id=885)
patch mars.h for D2

Should be using ptrdiff_t rather than int struct Interface.

Do we really need to worry about supporting objects with vtables > 32bit?  I don't think so.   Or is the d frontend already offset with a size_t offset and this fixes the runtime to properly deal with this?

I agree with Brad. There's no way this will be larger than 32 bits.
