[racket] -S / --search doesn't work on Windows?

Mac OS X:

bash-3.2$ ./racket -S /Users/greg/.emacs.d/lisp/geiser/scheme/racket/
Welcome to Racket v5.0.
> (current-library-collection-paths)
'(#<path:/Users/greg/Library/Racket/5.0/collects>
  #<path:/Applications/Racket v5.0/collects>
  #<path:/Users/greg/.emacs.d/lisp/geiser/scheme/racket/>)
>

Notice that the -S path is included.


Windows 7:

c:> racket -S C:/Users/Greg/site/geiser/scheme/racket
Welcome to Racket v5.0.2
>(current-library-collection-paths)
'(#<path:C:\Program Files (x86)\Racket\collects>)
>

Notice that the -S path isn't included.

I'm pretty sure this was a problem in 5.0.0 on Windows, too.
