 	* nscd/nscd_helper.c (open_socket): Now takes request type and key
 	as parameter.  Construct request record.  Try sending request
 	before the first poll use, it usually succeeds.  Adjust all
 	callers.
 	* nscd/nscd-client.h: Define MAXKEYLEN.
+	* nscd/connections.c (nscd_run): Don't define MAXKEYLEN here.
