[plt-scheme] FFI error in 4.0

[Jakub Piotr Cłapa]

define-cpointer-type has not been ported to 4.0 and doesn't work with 
the new _ handling.

#lang scheme/base
(require scheme/foreign)

#;(define-cpointer-type _test #f #f #f) ; this works
(define-cpointer-type _test)            ; this doesn't and gives a
                                         ; really obscure error message
