Subject: [Qemu-devel] [PATCH] configure: avoid compiler warning in pipe2 detection
Date: Mon, 20 Aug 2012 12:45:08 -0600 [thread overview]
Message-ID: <1345488308-10410-1-git-send-email-brogers@suse.com> (raw)
When building qemu-kvm for openSUSE:Factory, I am getting a
warning in the pipe2 detection performed by configure, which
prevents using --enable-werror.
Change detection code to use return value of pipe2.
