Don't worry about it. There are enough people compiling with newer gcc where the warning is not disabled that you won't be introducing in problems. > I've send out a new version of the patch (in fact a new series) > disabling the warning with a pragma only in the affected file. But isn't the problem that the use of pragmas to silence broken warnings is specific to newer gcc, while you are trying to silence the warning on older gcc? I guess I'll have to look at what you did; and I still need to work up my patch for the warning avoidance at configure time anyway. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
