The platform specific behavior is in library.scm, buried as a primitive:


(define ##sys#pathname-directory-separator
 (let ([st (software-type)])
   (if (and (eq? 'windows st) (not (eq? (build-platform) 'cygwin)))
   #\\
   #\/) ) )


This is wrong for a URL.  I haven't exactly figured it out, but it 
appears that make-pathname is being used for URL construction, which 
ultimately ends up with system-specific behavior when it shouldn't.  I 
am still jobhunting / trying to keep a roof over my head / avoid 
eviction 2 weeks hence.  I don't have the time to decide what the proper 
design should be.  Additional eyeballing appreciated.
