  16     Nothing particularly special happens here.
  17
  18     Back in the days of Windows 3.1, we would do something more useful here,
  19     as this is effectively the old-style equivalent of NT's "DriverEntry",
  20     though far more primitive.
  21
  22     In summary, we just implement to satisfy the MME API (winmm) requirements.
