[Ccrtp-devel] WSAENOPROTOOPT when instantiated RTPSession

On Windows XP with ccRTP 1.7.1 and Common C++ 1.7.3

I have a subclass of RTPSession for a client. It is throwing the
pointer to ost::Socket * as an exception when trying to open the
socket, the exact error is occuring in address@hidden

The bind fails, and then it calls the error handling routing, and
WSAGetLastError is returning 10042, which is WSAENOPROTOOPT. This is
defined as
"Bad protocol option. An unknown, invalid or unsupported option or
level was specified in a getsockopt or setsockopt call."
It seems that SO_REUSEADDR works fine on one of my Windows XP
machines, and not at all on this other machine, which always throws
the error.

Any ideas what might be going on here?

This has happened on 3 test machines, two with Windows XP SP2 and 1
with Windows XP SP3 (all but my development machine)
