--- Comment #4 from Dave Love <fx at gnu dot org> ---
Apologies, I was misled by something else; that option does affect the result.

However, this change in behaviour isn't mentioned in release notes, the error
message doesn't point to that option, and documentation suggests the code is
supported and that option is for something else.
