No, my bad -- this particular warning was caused by -Wwrite-strings,
which I noticed in the manpage, but didn't see it in the -Wall or
-Wextra lists, and forgot that I added it myself.  Sooooo, we can leave
-Wignored-qualifiers and ditch -Wwrite-strings, which is potentially
useful, but I think expendable.
