This isn't exactly what you were asking, but...
MzScheme provides CL-style "defmacro" in the "compat.ss" library.
Or if you don't need/want all of that particular library:
(define-macro defmacro
(lambda (name args . body)
`(define-macro ,name (lambda ,args ,@body))))
Just remember to use "." instead of "&rest". ;-} ;-}
[Confession: I never use R5RS macros myself, just "defmacro".]
