Not at the moment, but Tiger has a completely different design than
the SHA hashes, who are basically based on MD4/5. Thus, Tiger might
be able to withstand attacks that SHA-x is vulnerable to.

I understand that SHA-512 also has a completely different design, but that's
will still be readonly in most 1.4 setups (I assume that in 1.4 I still only
have to comment out that if(...) return statement in md.c to enable

Probably. But it still has no proven weaknesses I know of.
