Elizabeth Figura (@zfigura) commented about include/wine/dbt.h:
debugstr_w( data->event.handle.handle_file_path ), debugstr_guid( &data->event.handle.event_guid ), debugstr_w( data->event.handle.name ),
data->event.handle.data_size, data->event.handle.data );
(int)data->event.handle.data_size, data->event.handle.data );
These hunks should be fixed up to the commit that introduces them.
Note that if you're using DWORD (and you could just as easily use "unsigned int" instead) you probably want "%lu" rather than casting to int.
