mingw-w64 ddraw.h already has them, though they're inlined, gcc doesn't
like inlined data. DEFINE_GUID may need fixing, or at least instanced in
libuuid or libddraw.

I'll need to talk to to the Jacek from Wine to get a solution.

These may also need cooperation from Jacek.

The header details are actually scrapped from MSDN.
