51 The following code, when linked with libnotmuch.a and libutil.a does a
\r
52 passable imitation of sha1sum on amd64 (and I guess also i386) but
\r
53 computes a different digest on powerpc and probably sparc and s390x.
\r
55 In the long run we should maybe outsource hash computations to
\r
56 e.g. librhash, but I'd like a simpler fix for 0.17, if possible
\r
58 P.S. I blame Austin for adding the "missing-headers" test which found
