32 bits is een overflow op veel machines, en dan:

       unless the orig�-
       inal (non-negated) value would  overflow;  in  the  latter
       case,  strtoul()  returns  ULONG_MAX  and  sets the global
       variable errno to ERANGE.  Precisely the  same  holds  for
       strtoull() (with ULLONG_MAX instead of ULONG_MAX).
