[Qemu-devel] [Bug 1014823] Re: qemu-kvm-1.0.1 compilation error on Ubuntu 12.04

[Serge Hallyn]

Oh, actually I was about to mark this invalid, but in fact it is a valid
bug that it is trying to compile this bit of code when the AT* were not
defined.  There is a patch sent and acked upstream to fix this, so I'll
mark it confirmed for now.
