I cheat when I do that.  I leave out the __declspec(dllexport) and
the __declspec(dllimport).  I use --export-all-symbols and just create the
dlls with that.  That means none of the functions are hidden, but it wasn't
something I've needed for my own purposes.  I have scripts that will take a
static library I've built on Windows and create the dll from it if needed.

I didn't check if I needed both -DIN_LIBXML and -DLIBXML_STATIC but that
seemed to solve the problem.  I'm assuming the issue was just because I
built statically and it sounded like a Windows only issue.  I should
investigate this further when I have time.

It's on my list of things to test.  Spent the weekend trying to build the
latest version of graphicsmagick.  Haven't updated in a few years and I'm
also on a different computer and compiling statically now, so I needed to
update my scripts.

Nice.
