You could try to bind
(defun my-cpp-comment-region (beg end &optional arg)
(interactive "*r\nP")
(let ((comment-start "/* ")
(comment-end " */"))
(comment-region beg end arg)))
to a key.
BTW with comment-styles box / box-multi and newline terminated comment
syntax `comment-region' comments out the entire text from the beginning
of the region till EOL. The attached patch should cure that.
