New Revision: 5440

Modified:
   mpich2/trunk/src/mpid/ch3/channels/nemesis/nemesis/netmod/wintcp/wintcp_utility.c
Log:
Removing REUSEADDR option in windows tcp network module. In winsock REUSEADDR literally hijacks the port resulting in multiple processes listening on the same port when MPICH_PORT_RANGE is specified. This should fix ticket #894
