This brings the archive into synch with my harddisk... Everything in the lib directory should compile without problems (yes, even without warnings even if WARN=1). It is not well-tested, though, and there are some minor functions which must still be added. It is now almost usable. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@95 7894878c-1315-0410-8ee3-d5d059ff63e0
