[Qemu-devel] [qemu-kvm] build fail on i386 RHEL5u4

[Hao, Xudong]

Hi, 
Recently I build qemu-kvm on 32bit RHEL5u4/RHEL5u5, it will fail on fuction 
"vhost_dev_sync_region". But RHEL5u1 system is fine to build.
Did anyone meet similar issue?

qemu-kvm commit: 59d71ddb432db04b57ee2658ce50a3e35d7db97e

build error:
