Aha. I'll do that.

You have to admit, the error message is not helpful :-). A suggestion for the future: when bumping the minimum bootstrap compiler, it would be possible (in the same commit) to fix configure to complain about too-early versions?

Anyway I'm now building with 9.6, and doubtless that will be fine. Thanks.

Upgrade your bootstrap compiler to >= 9.4. We have now bumped HEAD's
version to 9.8, which means that 9.4 is the earliest possible bootstrap
compiler (which `text` now takes advantage of, as you see here). I have
a patch bumping the `configure` check stewing in my 9.8 preparation
branch.
