Ah, brilliant! Now I see what you are doing.

To summarize:

There are no changes to platforms/Cross or platforms/unix, and there is a
new platforms/Plan9 directory needed for the development that you are doing
for the Plan9 port of the Squeak VM.

Aside from that, your changes are in VMMaker (in the change set that you
attached to the Mantis issue) and these changes are needed to resolve issues
detected by the compiler on Plan9.

Thanks,
Dave
