macro aliases

Previously (and as per the manual) I could define a macro alias with
(define-macro new-name old-name)

This doesn't work any more---now, old-name is evaluated as a variable.
 Has this been changed?

Of course, one can still get the effect of an alias with
(define-macro (new-name . args) `(old-name ,@args))

so the problem is merely aesthetic.
