(Hmm - libvirt hasn't yet learned how to use tirpc on Linux, since 
rpc/rpc.h is directly in /usr/include on Fedora as part of 
glibc-headers; so I had to run 'make CFLAGS=-I/usr/include/tirpc 
LDFLAGS=-ltirpc', but that's an issue for the libvirt mailing list).

Meanwhile, this warning is a bit annoying; and did not happen with the 
older sunrpc headers.  Any chance you can silence them in a -2 release?

In file included from ././remote/qemu_protocol.h:9,
                  from remote/qemu_protocol.c:7:
/usr/include/tirpc/rpc/rpc.h:84: warning: redundant redeclaration of 
'bindresvport' [-Wredundant-decls]
/usr/include/netinet/in.h:21: warning: previous declaration of 
'bindresvport' was here
/usr/include/tirpc/rpc/rpc.h:95: warning: redundant redeclaration of 
'bindresvport_sa' [-Wredundant-decls]
/usr/include/netinet/in.h:22: warning: previous declaration of 
'bindresvport_sa' was here

But in spite of the warnings, I was still able to build libvirt on 
cygwin after today's upgrade, so good job on the release.
