Hi; this failed to build on my s390 box:

/home/linux1/qemu/block/ssh.c: In function ‘check_host_key_knownhosts’:
/home/linux1/qemu/block/ssh.c:367:27: error: implicit declaration of
function ‘ssh_get_fingerprint_hash’
[-Werror=implicit-function-declaration]
             fingerprint = ssh_get_fingerprint_hash(SSH_PUBLICKEY_HASH_SHA1,
                           ^
/home/linux1/qemu/block/ssh.c:367:13: error: nested extern declaration
of ‘ssh_get_fingerprint_hash’ [-Werror=nested-externs]
             fingerprint = ssh_get_fingerprint_hash(SSH_PUBLICKEY_HASH_SHA1,
             ^
/home/linux1/qemu/block/ssh.c:367:25: error: assignment makes pointer
from integer without a cast [-Werror=int-conversion]
             fingerprint = ssh_get_fingerprint_hash(SSH_PUBLICKEY_HASH_SHA1,
                         ^

It looks like that function was introduced in libssh 0.8.3, and this box
has 0.6.3. (configure has correctly not defined HAVE_LIBSSH_0_8
but this usage is inside a bit of code that's compiled even when
that is not defined.)

thanks
