Recent addition of C#8 features to mcs possibly broke this:

mcs -out:WidgetViewer.exe -r:../../glib/glib-sharp.dll -r:../../pango/pango-sharp.dll -r:../../atk/atk-sharp.dll -r:../../gdk/gdk-sharp.dll -r:../../gtk/gtk-sharp.dll ./TestCheckButton.cs ./TestColorSelection.cs ./TestRadioButton.cs ./TestRange.cs ./TestStatusbar.cs ./TestDialog.cs ./TestFlipping.cs ./TestSizeGroup.cs ./TestCombo.cs ./TestComboBox.cs ./WidgetViewer.cs
./TestCombo.cs(17,14): warning CS0612: `Gtk.Combo' is obsolete
./TestRange.cs(35,6): error CS0104: `Range' is an ambiguous reference between `System.Range' and `Gtk.Range'

./TestRange.cs(35,13): error CS0030: Cannot convert type `Gtk.HScale' to `System.Range'
./TestRange.cs(42,6): error CS0104: `Range' is an ambiguous reference between `System.Range' and `Gtk.Range'

./TestRange.cs(62,13): error CS0030: Cannot convert type `Gtk.VScale' to `System.Range'

This is because the compiler is resolving Range in the test as System.Range
instead of Gtk.Range, so we disambiguate it.

```

This is because the compiler is resolving `Range` in the test as `System.Range`
instead of `Gtk.Range`, so we disambiguate it.
