Re: [libvirt] [PATCHv2] build: avoid warnings on older gcc

The previous patch pulled in a newer version of stat-time.h from

a feature of newer gcc.  But we still aim to compile on RHEL 6.3,
with gcc 4.4.6 (not to mention even older devel platforms like
RHEL 5), which fails to build thanks to our development -Werror.

It took me a while to figure out how to make our set of warnings
smaller on older gcc without losing the benefit of the warnings
when using newer gcc (such as the one on Fedora 17), but this
should do the trick.

* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Avoid
warnings that gnulib can't silence on older gcc.
