Hi Michael,

Thank you but I find it odd that it's like that in your environment and I
have done nothing to either of these header files manually... anyway,
commenting out the entries in winbase.h worked to allow the compilation.
However, I have some interesting xvid.ax linking warnings that I wouldn't
mind your comment on since I believe it's related somehow:
