I don't like the duplication of the .def file. If our goal is to replace the visual studio project files with cmake, and you want to change the ABI, we should just change the ABI for all win32 builds.

Please also add some documentation about why the export list changed to the commit message, so anyone looking for the change has an easier time understanding the motivation.

I don't understand. You want from me also fixing Visual Studio solutions to use updated DEF file?

That's correct. If we're changing the vorbis.dll ABI I think we should change it for all the builds.
