  MFC r317372:
  scandir(3): promote arraysz to size_t to match numitems.
  
  The internal array size goes through a loop and is compared with numitems
  which at its limits makes can be unreachably higher than arraysz.
  Prevent an hypothetical overflow, and signed/unsigned comparison, by
  matching the types.
