  54         with an interesting thread to report the status for, instead of
  55         always reporting the status of the first thread.

  83         (win32_wait): If CACHED_STATUS was set, return that instead
  84         of doing a real wait.  Remove the code resuming the execution
  85         of the inferior after receiving a TARGET_WAITKIND_LOADED event
  86         during the initial phase.  Also remove the code changing
  87         OURSTATUS->KIND from TARGET_WAITKIND_LOADED to
