Obviously...

Ok, I tried more.
Apparently,

(define-syntax define-enumerate-type
  (syntax-rules ()
    ((_ name->int (name id) ...)
     (define-syntax name->int
       (syntax-rules (name ...)
	 ((_ name) id) ...)))))

works the same as

(define-syntax define-enumerate-type
  (syntax-rules ()
    ((_ name->int (name id) ...)
     (define-syntax name->int
       (lambda (x)
	 (syntax-case x ()
	   ((_ n) (free-identifier=? #'name #'n) #'id) ...))))))

. Now what about

(define-syntax define-enumerate-type
  (syntax-rules ()
    ((_ name->int (name id) ...)
     (define-syntax name->int
       (lambda (x)
	 (syntax-case x ()
	   ((_ n) (equal?
		   (syntax->datum #'name)
		   (syntax->datum #'n))
	    #'id) ...))))))

?
