Cannot bind to loopback address (127.0.0.1 or ::1) on Windows

[GoogleCodeExporter]

What steps will reproduce the problem?
Just bind to a loopback address.

What is the expected output? What do you see instead?
It failed with errno set to EADDRNOTAVAIL.

What version of the product are you using? On what operating system?
r9298, Windows 7 x64 (the library is compiled into x86)

Please provide any additional information below.

I think it failed because no interface could be found with a loopback address 
on Windows.
I took a look into the code and found that the function returns at 
sctp_pcb.c:3752.

Good export to github.
I just want to know whether this is solveavle, in the usrsctp stack.
If it is not, well, that's not a big problem. But I'll feel uncomfortable, as I must provide a different setting for Windows.
