#5: This is the final patch for stream/tvi_dshow.c, also handling the VARIANT
    issue.

#6: A new patch, necessary after stream/tvi_dshow.c compiles now, because a
    new error arised:

    loader/dshow/DS_Filter.o:(.rodata+0x10): multiple definition of `IID_IClassFactory'
    stream/tvi_dshow.o:(.rodata+0x10): first defined here
    loader/dshow/DS_Filter.o:(.rodata+0x0): multiple definition of `IID_IUnknown'
    stream/tvi_dshow.o:(.rodata+0x0): first defined here

    The Wine header not only declares these IIDs, but defines them, so
    redefining must be avoided.
