You can pull from the libxml2 branch of 
<https://github.com/bgilbert/openslide>.  I also updated CMake.

In the long term, I think mingw is the way to go for Windows.  But for 
now we probably need to keep supporting MSVC, so sadly no C99 for us. 
(This also means OpenSlide's C needs to be valid C++, preventing e.g. 
implicit casts of void pointers.)
