* time.c (wdiv, wmod): wdivmod0() assumes the 3rd and the 4th arguments

  are valid pointers.
  maybe checking them in wdivmod0() is better manner, but I guess that
  passing real dummy pointers may be faster than checking and branching
  in wdivmod0().
  this commit fixes SEGV on 32bit and LLP64 platforms.
