  This function will remove from the console event queue, any key-up events
  that are pending. under Win95 key-up events will incorrectly be translated
  into real key presses by the OS ReadFile() API call, which scanf() uses.
  The WinNT version of ReadFile() correctly ignores them, of course. The
  problem can occur when getch() is called to get a key, then scanf() is
  called to obtain more input from stdin.  On Win95 the key-up event that is
  still left in the event queue will cause ReadFile() to think that the same
  key was pressed again.  Although, good programming practice dictates that
  one shouldn't use both getch() and scanf() near each other in the same
  program, the following function could help alleviate this key-up problem.
  cscanf() does NOT suffer from this problem since it gets its input via
  getch() and not ReadFile().  __flush_win95_keyup_events() should be called
  before scanf() is called. Keep in mind that you must allow sufficient time
  for the user to release the key so that the key-up event is inserted
  before flushing the key-up events.  Otherwise, the key-up event will occur
  after scanf() is blocked and waiting inside ReadFile().

  __flush_win95_keyup_events() returns the number of key-up events that it
  removed from the queue.
