Unfortunately, if I remove importlib("stdole2.tlb"), generated .tlb seems
rejected to register into Windows COM+ Catalog.

Wine has stdole2.tlb in its fakedlls directory, but widl does not accept
this by

  error: Wrong or unsupported typelib magic 405a4d

Even if I copied native stdole2.tlb, widl fails with the same error.

Do you have any idea about this error?
