 2004-09-26 Hasso Tepper <hasso at quagga.net>
 
+	* *.[c|h]: Fix a lot of compiler warnings.
+	* isis_events.c: Remove isis_event_int_reach_change() function, as it
+	  doesn't make sense for now. Call lsp_regenerate_schedule() directly
+	  where needed.
+
+2004-09-26 Hasso Tepper <hasso at quagga.net>
+
 	* isis_lsp.h: Cast-as-lvalue extension is deprecated and is not
 	  accpted any more in gcc-4.0.
