I get errors like this related to %lld in format strings:

virsh.c: In function 'cmdDomblkstat':
virsh.c:990:9: warning: unknown conversion type character 'l' in
format [-Wformat]

The problem goes away when I replace the define for vshPrint

#define vshPrint(ctl, ...) fprintf(stdout, __VA_ARGS__)

by this function

static void
vshPrint(vshControl *ctl ATTRIBUTE_UNUSED, const char *format, ...)
{
    va_list ap;

    va_start(ap, format);
    vfprintf(stdout, format, ap);
    va_end(ap);
}

I'm not sure why this became a problem now, as vshPrint is a define
since 2006 and virsh used to compile before. Maybe this is an issue
with gnulib in the current libvirt-0.8.8-rc1 tarball, as I'm testing
based on this tarball it.

Are you compiling this from a git checkout or a tarball?
