I considered this, but then recalled that maybe the C standard doesn't
guarantee binary compatibility between different pointer types so it
wouldn't be guaranteed to be better.  (Even if this isn't the case,
the GNUTLS types aren't guaranteed to be pointers at all, but we
already cheat during initialization, so...)

But I guess in practice it works, so I changed it, thanks.
