I guess so. Is there a tool like `nm` we can use to extract that information on windows? I guess mingw has something very similar, probably even `nm` itself, but I'm not aware of an equivalent for MSVC.

I've uploaded a new version which should hopefully fix the issue. I don't have a windows environment available, so it's not easy to test for me.
