Details:

I am using the latest Kawa from CVS.

I wrote a file named p1.scm which contains:

(define numbers ())

Then in macros.scm I have:

(define-macro (push! value where)
  (let ((val-name (gentemp))
        (loc-name (gentemp)))
    `(let ((,val-name ,value)
           (,loc-name (location ,where)))
       (set! (,loc-name) (cons ,val-name (,loc-name))))))

Then I have another file p2.scm with:

(require <p1>)

(push! 10 numbers)

And I use these commands to compile them:

kawa -C p1.scm
kawa -f macros.scm -C p2.scm

And I get this error:

(compiling p2.scm)
