[libvirt] Build failure on RHEL-5

[Chris Lalancette]

Hello,
     My autobuild of libvirt on RHEL-5 failed last night because of:

if gcc -DHAVE_CONFIG_H -I. -I. -I..    -I../gnulib/lib -I../gnulib/lib -I../include -I../include -I../src -I../src/util -I../src/conf -I../src/remote -I/usr/include/libxml2      -Wall -Wformat -Wformat-security -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wextra -Wshadow -Wcast-align -Wwrite-strings -Waggregate-return -Wstrict-prototypes -Winline -Wredundant-decls -Wno-sign-compare -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fasynchronous-unwind-tables -fdiagnostics-show-option -Werror  -DLOCAL_STATE_DIR="\"/usr/local/var\""  -DSYSCONF_DIR="\"/usr/local/etc\"" -DQEMUD_PID_FILE="\"\"" -DREMOTE_PID_FILE="\"/usr/local/var/run/libvirtd.pid\"" -DGETTEXT_PACKAGE=\"libvirt\" -D_REENTRANT   -g -O2 -MT libvirtd-dispatch.o -MD -MP -MF ".deps/libvirtd-dispatch.Tpo" -c -o libvirtd-dispatch.o `test -f 'dispatch.c' || echo './'`dispatch.c; \

>From a quick look, I can't quite see what it is complaining about; args is clearly
used later in the function, so it's kind of weird.  Anyway, if anyone has time to
look, it's probably something we should fix.
