+Subject: [PATCH] ctkvdpau: Fix CFLAGS=-fno-common
+
+GCC 10 will enable -fno-common by default[0], which causes the linker to
+fail like this [1], even for older GCC versions for which it is
+explicitly enabled:
+
+```
+/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld:
+./gtk3/ctkvdpau.o:/home/jer/portage/x11-drivers/nvidia-drivers-440.44-r1/work/nvidia-settings-440.44/src/gtk+-2.x/ctkvdpau.h:70:
+multiple definition of `VDPAUDeviceFunctions';
+./gtk3/ctkwindow.o:/home/jer/portage/x11-drivers/nvidia-drivers-440.44-r1/work/nvidia-settings-440.44/src/gtk+-2.x/ctkvdpau.h:70:
+first defined here
+
+```
+
+Fix this by declaring VDPAUDeviceFunctions as extern and by defining it
+explicitly.
