[libvirt] Compiler warnings

Hi all, I meet the following compiler warnings today: ...... CC libvirt_util_la-buf.lo util/buf.c: In function 'virBufferEscape': util/buf.c:430: warning: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] CC libvirt_util_la-command.lo ...... CC libvirt_lxc-buf.o util/buf.c: In function 'virBufferEscape': util/buf.c:430: warning: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] CC libvirt_lxc-command.o ...... Has anybody the same experience? Thanks, Alex
