[Cuis-dev] FYI: Cuis on Aarch64 and fixes for current on Amd64

[Eric Gade]

Hi Ken,

Do you have a specific set of instructions that you follow for compiling
the aarch64 cog? Are you cross-compiling or doing it on aarch64 hardware?
The last time I tried to get this to compile I ran into errors that I
couldn't understand (beyond my level).

I am asking, in part, because I was a backer of the MNT Reform laptop
<https://www.crowdsupply.com/mnt/reform>, and I'm really hoping to be able
to use Opensmalltalk based systems on it.
