I was taking a look at this issue before this patch, and it seems that
of these errors with acpica are the same as one that has happened
before for mips64, as in fixed by:
https://patchwork.ozlabs.org/patch/521624/
I'm trying a similar patch to that to fix this error in acpica.
In case you can wait a bit for that, maybe fixing it in the same way
as micropython would be a patch easier to upstream.
Thanks,
?rico

-Werror is a *development* opiton; it should not be used in a *release*.
Fact is, warnings are added with new versions of the compiler, so when
we update to a newer version and keep -Wall -Werror, and the code hits
such a new warning, we'd still get build issues for code that might even
be correct with an overly pessimistic compiler.

Even if you manage to fix those very warnings, I still believe this
patch to be valid and applied.
Granted, we could turn it into something that is acceptable upstream, to
only enable (or disable) use of -Werror at will.
Regards,
Yann E. MORIN.
