There's a bug in the 1.7 handling of macros like this one:

(define-syntax one
  (syntax-rules ()
    ((one var)
     (begin
       (define extra 1)
       (define var extra)))))

invalid define syntax.  This is due to the (define extra 1) part, as the
following macro works:


I checked in a fix for this, as well as your testcase.  Thanks.
