Chicken's bit-set? is not from SRFI-60.  It has a swapped argument order.
See the manual:
http://api.call-cc.org/doc/library/bit-set%3F

If you want, you can use the SRFI-60 egg to get compatible behaviour:
http://wiki.call-cc.org/eggref/4/srfi-60

(by the way, it would be nice if its author could put the docs in a wiki
 page so that api.call-cc.org can pick up on it)

Cheers,
Peter
