getdents[64] have also signedness problems

ulimit.h should be used for both cases, but syscall2() is not in sync 
with the prototype, that's why I haven't corrected that.

better
extern __typeof(vfork) __vfork attribute_hidden;

changes in the header, and if we change anything in the header, we will 
get a warning/error here.
