It seems that the definition of BIO_reset() is the same in 1.0.1e as in

I was assuming that the value computed that is not being used is 'b' or some
internal state, but I can't see how that is the case. I think it's actually
the result of the function - which is being cast, otherwise your compiler
would just ignore it.

I presume you're using the RHEL-6 compiler?
