That's a Windows API - the Linux equivalent is AF_VSOCK: please feel free to
submit support patches to cygwin-patches to support AF_VSOCK using AF_HYPERV or
newlib to support AF_VSOCK.

You could check to see if the Windows oriented mingw or msys projects support
AF_HYPERV yet.

These interfaces are fairly new and OS specific so there is not yet a facility
abstraction to support.
