I applied patches that prevented the x86 patches from even being built
on a modern system (i.e. my laptop).  I didn't add any new
functionality, I just wanted to verify that there were no regressions,
which is hard to do when the tests do not build.

As for what to run, yes, use the latest possible seems like the best
solution so far.
