    Hack to include glib/gdatasetprivate.h directly
    
    The gdatasetprivate.h header includes gatomic.h directly. It all works
    well in GLib, but inside GObject it will trigger the single inclusion
    guard.
    
    Since this is a private header, and it's kind of a special case, one way
    to fix it is to declare GLIB_COMPILATION around it and fool the single
    inclusion guard in gatomic.h into thinking we're compiling GLib and not
    GObject.
