Subject: Re: [OMPI users] Problem with MPI_Comm_accept in a dynamic client/server application

Hi Kalin,

These warning messages are harmless, some of the IPv6 feature is not yet
supported on Windows, but it can still run with IPv4. If you want to get
rid of these messages, just disable the IPv6 support in CMake.
