match macro problem

I'm having trouble with a macro that expands into a use of
 match from Andrew Wright's match-s48.scm:

A very simple example of the problem:

  > (define-syntax m
      (syntax-rules ()
        ((_) (match 1 (x 2)))))
  > (m)

  Error: syntax error in pattern
         #{Generated x 1455}

Since match is not implemented with define-syntax and syntax-rules,
 I assume I'm running into a problem mixing the two styles.
