GTK-3.x: Fix builds against latest stable GLib with Visual Studio
Hi,
glib-2.68.x and later regard warnings C4715
(not all paths return a value) and C4098
('void' function returning a value) as errors, so this MR attempts to address these issues in the code, so that things will continue to build against the latest stable GLib with Visual Studio.
With blessings, thank you!
