I still think that somehow you're building for kernel space. The reason 
for this is the following items in your output:

This module.h is only included (on my system) when __KERNEL__ is defined 
when compiling i2c.h
Which version of the kernel headers are you using? That warning message 
in list.h is on line 713 on my system.

On more thing to check is
 gcc -v -E -dM test-i2c.c > defines-test-i2c.lst
 gcc -v -E -dM test-i2c.c 2> defines-test-i2c2.lst

This list all the defines gcc uses when compiling test-i2c.c. Maybe we 
can find something there. Just send me the output for comparison.

I am going to update to the latest kernel version/headers, see what 
happens there.
Note: I am using linux-headers 2.6.8
       and kernel 2.6.10
Can any one explain why this is different :-\
