[plt-scheme] r6rs define-struct and gensym

Just in case other people are wondering as well.

Gensym can still be loaded (although you might not want to do that 
anymore; and Chongkai was right in my case

#!r6rs
(library
 (Test)
 (export gensym)
 (import (rnrs)
         (only (scheme) gensym)
         (rnrs io ports))
 (display (gensym)))
