Take out one of the close brackets and change the semicolon to a comma:
OUR_GUID_ENTRY(CLSID_Sourcefilter_AVI_WAV,
0xd3588ab0, 0x0781,0x11ce, 0xb0,0x3a, 0x00 ,0x20, 0xaf ,0x0b,0xa7,0x70);
x0b,0xa7,0x70);
Becomes:
OUR_GUID_ENTRY(CLSID_Sourcefilter_AVI_WAV,
0xd3588ab0, 0x0781,0x11ce, 0xb0,0x3a, 0x00 ,0x20, 0xaf ,0x0b,0xa7,0x70,
x0b,0xa7,0x70);
