No, no, there are no problems. First, I don't see how changing the
internals of a function like an hashing function would change the Binary
Interface. Second, in general, we make no guarantees as far as the tr1
bits are concerned, this is also *explicitely* stated in the release
notes. Really, please reconsider the issue, there are no problems.
