[Nice] libnice always crashes under FreeBSD AMD64

[Igor Serikov]

   Youness,

Thanks you! I renamed the function & recompiled. It works. Somehow, I 
had this idea to just did not check it further.
Just make the change permanent, so all future versions will have it.

Another one. I believe it is a known thing. AMSN->WLM2009 is OK now but 
not the other way around. When I try to "call computer", the Windows 
says: "Messenger is not available right now." What could it be? Again, 
both PCs are on the same local network with NAT (another FreeBSD box 
acts as a router. I use PF (http://www.openbsd.org/faq/pf/) on it. No 
UPNP, of course).

   Thanks,
     Igor.
