First, Can I download a beta of  3.4.8, or any other version with that
fix? It's pretty urgent

Secondly, how are fifos, other device nodes and mknod implemented? You
encode them as softlinks on ntfs? What about Windows native NFSv3
driver, do you use native mknod then to create a fifo? Where can I
find the code in cygwin for that?

Thanks,
Martin
