The issue still exists on Windows. The following pipeline fails because the TTL
option could not be set (Windows error code 10022 WSAEINVAL, i.e. "An invalid
argument was supplied"):
gst-launch-0.10 --gst-debug=*udp*:5 filesrc location=<some_small_file> !
udpsink port=5000

Output is:

******************

gstreamer version is 0.10.36, issue reproduced on Win Vista and Win 7.

In gstmultiudpsink.c at line 886, failure to set the TTL seems to be considered
as fatal, but it shouldn't on Windows. From the MSDN documentation, IP_TTL
support is not required and may not be supported.
