I haven't tried Win95, but in NT the following works:
(win:winhelp (pc:window-handle *whatever*)
               filename
               win:help_context 
               (let ((u (ct:ccallocate (:void *))))	; ugly, but only
temporary
                 (setf (ct:cpointer-value u) context)
                 u)
               :static)

I don't know why I have the "temporary" comment.
