Install Visual Studio 2015 with only the Windows 8.1 SDK selected, open a Visual Studio command line prompt, clone gst-build and build it with Meson. You'll get the following error:

This error is confusing to me because I have no idea where those symbols are coming from. Probably a header? But we guard all our header includes.
