The error happened when compiler tried to build restorer.c which happens a way
earlier than "normal" .c files. And in restorer we use own syscall table with
headers so the compiler knows the function declaration.

I'm trying to say that if headers are indeed too old, we will have an error in
compilation anyway but it'll be related to getpriority libc implementation
rather than PRIO_PROCESS definition.

Need to think...
