	Okay, here's a patch which adds a LIBVIRT_COMPILE_WARNINGS autoconf
macro from GNOME which I've always found very, very useful.

	I've changed it to include all the flags we were using.

	The brilliant thing about this is that you can choose, while hacking,
to build with --enable-compile-warnings=error if you want to use -Werror
to catch any warnings you've introduced.
