--- Comment #1 from Andrew Waterman <andrew at sifive dot com> ---
It turns out there is no such thing as the B extension; it was a working name
for a draft proposal a few years ago but wasn't (and presumably won't be)
ratified. The correct behavior is to reject B but accept zba, zbb, zbc, and
zbs.
