For dynamic-wind, yes.  There is still eval and interaction-environment
missing (which means also REPL semantics, specifically the replacement of
top-level definitions by new ones) and the broken model of the undefined
order of evaluation (it shuffles the order, but only once per lexical
instance of a procedure call, not per call).

It would be so in a system that allows definitions and expressions directly
in libraries (a non-portable extension) and allows library declarations
intermingled with code (another non-portable extension).

Fixed, thanks.  I added to the rationale that the port can always be
set using the current-output-port parameter.
