I have also used gnuwin32 to use OLE & COM objects.  I think directx
uses a similar interface.  It's not easy, you must use C not C++ for
now.  C++ cleans up your code alot, but it doesn't compile the Microsoft
headers at all.  For some reason the g++ is more peticular about the
location of * in a function prototype that returns a pointer.

The directx sample doesn't have any problems since it uses C.

For instance,
int * __stdcall foo();

gives an error.  but

int __stdcall * foo();

does not.

Another thing is that if you declare the calling convention for a member
function of a class, the calling convention is ignored.  This may pose a
problem since OLE expects stdcall for member functions of COM objects.

Hope this helps.
