$NetBSD: patch-prnt_hpijs_hjzjscolor.cpp,v 1.1 2012/06/23 04:50:07 schnoebe Exp $

use strlen(3) instead of strnlen(3), for use on NetBSD 4.0 and earlier
as well as other systems that don't have strnlen.

Ideally, the configure script would check for strnlen, and include a
replacement  implementation if required.
