[Devel] udp_server.c patch

[Federico Giannici]

I just installed OpenSER 1.0.0 on OpenBSD 3.7 amd64. Previously I was 
using SER 0.9.4.

When I launched OpenSER it give the following error:

  0(0) ERROR: udp_init: setsockopt(IP_MULTICAST_LOOP): Invalid argument


Comparing your source with the SER one, I tryed the attached patch and 
it solved the problem.


Bye.
