From 87751797c707092108700159b570e917bae346b9 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Fri, 16 Sep 2011 22:03:08 +0200 Subject: Fix and clean code which tests the gcc version The code which tests whether gcc supports warn_unused_result was wrong. Remove the wrong test from configure and replace it by code using macro QEMU_GNUC_PREREQ in compiler.h.
