[libvirt] PATCH: 16/25: Fix GNULIB warnings on Mingw

The GNULIB Makefile.am doesn't set any particular compiler warning
flags in the belief that upstream GNULIB developers sort out all
warnings before committing their code. This is reasonable for builds
on mainstream Linux platforms, but MinGW builds of GNULIB don't
have nearly the same level of testing. So This patch adds the libvirt
$(WARN_CFLAGS) to the gnulib Makefile.am and then fixes the problems
this showed up. Nothing of consequence really. Leave it upto gnulib
developers whether its worth fixing these.
