+ * Revision 1.99 2007/08/05 13:42:22 fabiankeil
+ * #1763173 from Stefan Huehner: declare some more functions static.
+ *
+ * Revision 1.98 2007/05/14 10:33:51 fabiankeil
+ * - Use strlcpy() and strlcat() instead of strcpy() and strcat().
+ *
+ * Revision 1.97 2007/04/09 18:11:35 fabiankeil
+ * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
+ *
+ * Revision 1.96 2007/03/08 17:41:05 fabiankeil
+ * Use sizeof() more often.
+ *
* Revision 1.95 2007/02/10 17:01:37 fabiankeil
* Don't overlook map result for the forwarding-type.
