Thanks, but there are still left-overs:

> +(defcustom cpp-message-min-time-interval 1.0
> +  "Indicate the minimum time interval in seconds that
> +`cpp-progress-message' should print messages.

This should be one line, so the sentence should be shorter to fit.  If
you drop the redundant "Indicate the" part, it will come close.

> -(defvar cpp-progress-time 0)
> -;; Last time we issued a progress message.
> +(defvar cpp-progress-time '(0 0 0 0)

You could leave it at 0, no need to have a list here.

> +  "Indicate the last time `cpp-progress-message' issued a
> +  progress message.")

This should be a single line.  Once again, please drop the uneeded
"Indicate" part.

>  (defun cpp-progress-message (&rest args)
> -  ;; Report progress at most once a second.  Take same ARGS as `message'.

> +  "Report progress by printing messages at most once every

The first sentence of the doc string should take only one line.
