Sorry for the delay in replying. I'm not sure if you're aware, but when
you have an unregisterised 6.6 working, you can use that to build an
unregisterised 6.8 and later versions. Building the unregisterised 6.6
would just be a stepping stone to the latest version, and only needs to be
This may be moot if we get bootstrapping working again, but until then I'd
guess going via 6.6 is the easiest route.
For the registerised port, you really need a native code generator (the
mangler is on death row, yay). At a rough guess, I'd say porting the NCG
would take a couple of weeks or so for someone unfamiliar with the code.
Hopefully we'll improve that when we refactor the NCG as part of the
