[Qemu-devel] [PATCH 2/2] configure: Fix errors in test for__sync_fetch_a

From: Stefan Weil
Subject: [Qemu-devel] [PATCH 2/2] configure: Fix errors in test for__sync_fetch_and_and
Date: Sun, 15 Jul 2012 20:34:32 +0200

The old test code raises two compiler warnings which are errors since
commit 417c9d72d48275d19c60861896efd4962d21aca2.

These errors could result in compilations with compiler flag
-march486 (so all nice features of newer processors got lost).
