All the above it caused by you including <linux/i2c.h>. As explained
before, this is a kernel-only header file, which you must _not_ include
in user-space code. You are not the only one to blame though, as in
fact this header file should not be in /usr/include at all, this is a
mistake which should be fixed "soon".

And this one is because you forgot to add the following at the
beginning of your code:

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

(From "man open".)

So the key is to include the right header files. No kernel header,
i2c-dev.h from the lm_sensors project, and any standard header you need
for the functions you use (For example printf requires <stdio.h>, ioctl
requires <sys/ioctl.h>, etc... Use "man <function name>" to find out.)
