[libvirt] [PATCH] poll: don't return uninitialized

Daniel Berrange fixed this yesterday. http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=74e2d5b2fd5 It's in gnulib now, along with a change to make the cpp nesting a little more readable. This pulls the update poll.c into libvirt: Thu Jan 8 09:48:04 CET 2009 Daniel P.
