You are not supposed to include i2c.h from user-space. You should only
include i2c-dev.h, and this should be the one that is shipped in the
i2c-tools [1] package, NOT the one in the kernel tree.

I know that this is error-prone (although it _is_ explained in the
document you mentioned) and that's one thing I intend to fix in the
course of year 2008.
