Sorry, still catching up on this.  The R5RS description
of `eqv?' is completely unambiguous in requiring the
"different" semantics.

R6RS loosened the semantics slightly to make NaN
`eqv?' comparisons unspecified.

Neither the "same" semantics (used only by SCM) nor
the "same*" semantics are described by any standard.

Pending a re-vote I'll change the draft to the unspecified
(R6RS) semantics, and urge people to vote for this.  As
I stated in my rationale, this is the de facto standard
anyway.
