I have not been able to reach Ken Dickey, author of this SRFI, for this or earlier issues.  Therefore, I've added a description of this issue, with a link to our discussion, to the errata document linked from SRFI 48.  I did apply the patches that Shiro Kawai and I prepared, though, since they are in the implementation itself, not the normative parts of the document.

If someone does fix the remaining issues, I'd be grateful if they contributed the patches.

Thanks.
