The problem was observed when building for acorn26, but that's
just because it's early in the alphabetical sorting; I guess at
least any arm port (and probably several others) would croak on
the code the way it was...

You probably also saw the printf format fix to
src/crypto/external/bsd/openpgpsdk/dist/src/lib/keyring.c that I
also committed.

OK, sounds good.
