+        avoid a sign-extension bug in crypto_hash_function
+        * fns.c (to_uchar): Define.
+        (crypto_hash_function): Use it to convert some newly-signed
+        variables to unsigned, to avoid sign-extension bugs.  For example,
+        without this change, (md5 "truc") would evaluate to
+        45723a2aff78ff4fff7fff1114760e62 rather than the expected
+        45723a2af3788c4ff17f8d1114760e62.  Reported by Antoine Levitt in
