 *         Original implementation as dprintf[_]ver_string
 *      05-Jul-1997 Dave Cuthbert (dacut@ece.cmu.edu)
 *         Fixed problem that caused bug with tools/make_debug -- renaming
 *         this function should fix the problem.
 *      15-Feb-1998 Dimitrie Paun (dimi@cs.toronto.edu)
 *         Modified it to make it print the message using only one
 *         dprintf[_]ver call.
