+Subject: [PATCH] fix build on gcc-10 (-fno-common)
+
+gcc-10 changed the default from -fcommon to fno-common:
+  https://gcc.gnu.org/PR85678
+
+As a result build fails as:
+
+    ld: i3lock-unlock_indicator.o:(.bss+0xc): multiple definition of
+      `input_position'; i3lock-i3lock.o:(.bss+0x3c): first defined here
+
+The change turned one of definitions into declaration.
