portmap is not IPv6-aware. There is a replacement, rpcbind, which does
support IPv6. I have a partially-ported version of that sitting on my
hard drive, but it doesn't seem to actually work. If any body is
interested in using it as a starting point for a portmapper replacement
on cygwin, I can make it available.
(I also have a simple rpc client and server package that can be used to
test rpcbind)
