I found '4D 53 46 54' at offset 0x300 of stdole2.tlb.
Wine's stdole2.tlb also have the signature at offset 0x738.

(might have an additional header before the main part?)

Widl accepted the wine's stdole2.tlb when I removed the header,
but still, the generated qga-provider.tlb was not accepted by Windows...:(
