IllegalAccessError in latest cvs version

[Thomas Kirk <tk at research dot att dot com>]

the latest cvs version of Kawa produces an error in the MS JVM under some
circumstances when binding a lambda expression. The first two forms
produce an IllegalAccessError; the third, in which a variable from an
enclosing let is referenced within the lambda, works fine.

This error does _not_ occur with the Sun JVM, so it's not clear that this
isn't a microsoft bug, but it wasn't a problem with 1.6.70.



;;; error
(define foo (lambda () ()))

;;; error
(define foo1 (let ((n 0)) (lambda () ())))

;;; ok
(define foo2 (let ((n 0)) (lambda () n ())))
