On a recent mingw-users thread, a point was raised around the way headers are developed (public documentation, clean room, reverse engineering etc.) and it made me wonder about our directx patches. This:

*  File:       dinput.h
*  Content:    DirectInput include file

makes it seem like an unlicensed copy of Microsoft sources.

Any thoughts?
