Thanks for all the answers! Seems like rdmd did the trick.
I don't see why this isn't built in to dmd though, or does it cause
overhead when you are using rdmd? Benefits, Drawbacks?
I've also stumbled upon an additional error with the win32 DirectX
bindings, but this seems D related actually.

Everyone we'll keep asking that question forever until the D compiler does this

Maybe you are able to wrap that memcpy in a templated D function (named
copyMemory) that does what you want in a bit safer way,
