Odd...  I don't get that warning on F12 or rawhide.
Which version of gcc are you using?
Any added options, beyond those provided by this:
./autogen.sh --enable-compile-warnings=maximum

ACK.  That's safe.
Confirmed: it's the change that would be produced by sed s/%-0/%-/,
and virsh.c is the only affected file.
