+Subject: [PATCH] src/headers/daemon.h: avoid redefinition of
+ 'last_selection_time'
+
+Noticed build failure on gcc-10 as:
+
+```
+gcc  -L/home/slyfox/dev/git/gpm/src  -o gpm mice.o ... report.o tools.o   -lm
+ld: twiddler.o:gpm/src/headers/daemon.h:183:
+  multiple definition of `last_selection_time'; mice.o:gpm/src/headers/daemon.h:183: first defined here
+ld: synaptics.o:git/gpm/src/headers/daemon.h:183:
+  multiple definition of `last_selection_time'; mice.o:git/gpm/src/headers/daemon.h:183: first defined here
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+https://gcc.gnu.org/PR85678.
+
+The error also happens if CFLAGS=-fno-common passed explicitly.
