32 * followed by the address of teststring and the string it contains if
33 * teststring is non-null or "(null)" otherwise, and then the epilogue

36 * Revision history
37 * 30-May-1997 Dave Cuthbert (dacut@ece.cmu.edu)
38 * Original implementation as dprintf[_]ver_string
39 * 05-Jul-1997 Dave Cuthbert (dacut@ece.cmu.edu)
40 * Fixed problem that caused bug with tools/make_debug -- renaming
41 * this function should fix the problem.
42 * 15-Feb-1998 Dimitrie Paun (dimi@cs.toronto.edu)
43 * Modified it to make it print the message using only one
44 * dprintf[_]ver call.
