Hi Alaios, 

It's because you've misspelled the -D __KERNEL__ as -D __KERNEL when
you invoke gcc.

The printk declaration in kernel.h is protected by a #ifdef
__KERNEL__, and if you don't define that symbol at compile time, the
printk declaration won't get pulled in at compile time and the
compiler yells at you. But you knew that, right :-). It's just a bad
old typo.

Hope this helps :-)

Regards,
Karthik.
