[ Apologies if duplicated.  Previously sent from non-subscriber address. ]

The SRFI document currently states:

(define-imported-c-binding string obj)
(lookup-exported-c-binding string)

     Define-imported-c-binding and lookup-exported-c-binding are Scheme
     versions of scheme_define_exported_binding and
     scheme_lookup_imported_binding.

But I don't see mention of scheme_lookup_imported_binding anywhere else.
