No, that came later. I had one of the very original ones.

I'm pretty sure it was that Jensen platform, but I'm too lazy to go
back and look.

I ended up hacking something up which was enough to show the build
problems, and then some.

But your config shows _other_ errors with the IO functions, so I guess
I'll need to look at that one too.

There's clearly a reason that Jensen was marked BROKEN in the Kconfig,
the whole situation with the IO accessor functions on that platform is
a disaster.
