I think putting these annotations in the .c files does not make any
sense, since external code calling these functions will not see it.
Also, it's probably a good idea to define __printf() and make it no-op
in case GCC is not used.

Another thing: Please don't fix different unrelated things in the same
patch, send multiple patches instead.
