[Qemu-devel] Compilation error on Ubuntu 6.06 and 7.10 with gcc-3.4

[Brad Campbell <brad@wasp.net.au>]

G'day all,

Getting this on my two development machines with up-to-date CVS as of now..

I did a complete directory removal and fresh CVS checkout just to be sure.

Configured with..

./configure --target-list=i386-softmmu --enable-alsa


gcc-3.4 -Wall -O2 -g -fno-strict-aliasing -fomit-frame-pointer -I. -I..
