This is because it doesn't distinguish between Gio, GioUnix and 
GioWin32, and in particular assumes that the former Gio.DesktopAppInfo 
(which now only exists in GioUnix) will exist in the Gio library on 
non-Windows platforms (search for new_from_filename in 
src/APILookupGio.txt).

UnixMountEntry and UnixSocketAddress likely have the same problem.

The Unix-specifics in src/APILookupGLib.txt (unix_error_quark, etc.) 
probably also have this (search for !Windows).
