+ * have_newstr - Determine if we have a system without ANSI C string functions
+ *
+ * usage:
+ *	have_newstr
+ *
+ * Not all systems support all ANSI C string functions, so this may not
+ * compile on your system.
+ *
+ * This prog outputs several defines:
+ *
+ *	HAVE_NEWSTR
+ *		defined ==> use memcpy(), memset(), strchr()
+ *		undefined ==> use bcopy() instead of memcpy(),
+ *			      use bfill() instead of memset(),
+ *			      use index() instead of strchr()
