Wild guess - if you look in sqUnixMain.c (around line 900) you'll notice that the ARM related tests are ARM32 specific so the trick is probably to find the relevant defines. Another wild guess - __arm__ will stay, __arm32__ will be replaced by __arm64__ and ARM32 by ARM64.

Ken,

Thank you for the update to cmake/config.guess to add support for
building the interpreter VM on aarch64. I committed your updates to
the SVN repository.
