It turned out that an even dozen patches were required in order to get the selftests building cleanly, and all running, once again. I made it worse on myself by insisting on using clang, which seems to uncover a few more warnings than gcc these days.
So I still haven't gotten to my original goal of running a new HMM test that Alistair handed me (it's not here yet), but at least this fixes everything I ran into just now.
