+
+	* src/orb/GIOP/giop-recv-buffer.c (giop_recv_buffer_get): 
+	1) Handle the LINK_TIMEOUT connection status. 
+	2) Added new function parameter to communicate the timeout 
+	   status to callers. 
+	(giop_timeout_add): New function to add a timeout thread.
+	(giop_timeout): Timeout thread function. Will wait using nanosleep 
+	until the timeout expires. Will change the link state 
+	to LINK_TIMEOUT and signal wait condition.
+
+	* src/orb/orb-core/corba-object.c (ORBit_try_connection_T): 
+	Handle a timed out link just like a disconnected link.
+
+	* src/orb/orb-core/corba-orb.c: The ORB command line option: 
+
+	   GIOPTimeoutLimit
+
+	is no more. It has been changed into:
+
+	   GIOPTimeoutMSEC - IPv4/6 timeout limit in milliseconds 
+
+	It defaults to 60 seconds. This options controls the timeout 
+	limit for GIOP connections, but only for IPv4 and IPv6 
+	connections. Setting it to zero will explicitly disable any 
+	timeout control.

+	* src/orb/util/orbit-options.c (ORBit_option_set): Support parsing

+
+	* src/orb/util/orbit-options.h (enum): Added support for 
+	unsigned long option values.
+
+	* Reverted previous GIOP timeout patch after having discussed
+	my flawed approach with Michael.
