Ah, nevermind <220113.86v8yntxfb.gmgdl@evledraar.gmail.com>, so you meant *want[] :)
I can confirm that this works on the xlc version that errored on this before, the reftable tests even pass!

Would make sense to steal the compiler version etc. details from my <patch-1.1-7425b64c0a0-20220113T113821Z-avarab@gmail.com>. I.e. eventually we'll be able to change this & other code back, as nobody will care about that older compiler version. It worked before in the pre-image on a more recent xlc.
