[Live-devel] Problem receiving data on Windows XP (Volker Marks)

[Volker Marks]

D'oh!

After several days of heavy debugging I've found the reason for all the
network/multicast issues:

Somehow I had lost the define "WINNT" in my groupsock-project-file. 
This led to the inclusion of "winsock.h" instead of "ws2ipdef.h" and this
led to e.g. a wrong value for "IP_ADD_MEMBERSHIP".

Embarrassing...
