OK scrap that. Noone's going to modify MS headers. But it happens 
because you assume wchar.h is included which is not the case. So the 
solution is to include wchar.h in your file.

Much worse. It doesn't know INT8, INT16, UINT8, UINT16, int8_t, int16_t, 
uint8_t, uint16_t. So I think it's better to use char and short for these.

I attach a version working with VC++ Express (also VS2005) and VC6.
