Thanks, your patch is already the third fix I am aware of.
That is one of the issues with build problems like this: once it is
upstream, too many people become affected, and write a patch.
And all of that could have been avoided if the buggy commit was not
included in a PR _after_ the breakage was reported...

Now back to bisecting other runtime breakage in next...
