Subject: configure: include stddef.h for NULL
From: Scott Wood <scottwood@freescale.com>
X-Patchwork-Id: 66742
Message-Id: <20101004211700.GA27097@udp111988uds.am.freescale.net>
To: QEMU Developers <qemu-devel@nongnu.org>
Date: Mon, 4 Oct 2010 16:17:00 -0500

This fixes an observed failure to detect madvise() on Linux.

To avoid similar issues, all other tests that use NULL but don't already
have stddef.h are also fixed.
