+From 5791564dd934d193df771a0a7c52013e9f456aa1 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] fg_gl2: fix build failure against gcc-10
+
+On gcc-10 (and gcc-9 -fno-common) build fails as:
+
+```
+[ 31%] Linking C executable bin/Lorenz_static
+/usr/bin/cmake -E cmake_link_script CMakeFiles/Lorenz_static.dir/link.txt --verbose=1
+/usr/lib/ccache/bin/cc  -Wall -pedantic  -rdynamic CMakeFiles/Lorenz_static.dir/progs/demos/Lorenz/lorenz.c.o \
+   -o bin/Lorenz_static  -lGLU -lGL -lm -lX11 -lXrandr -lXxf86vm -lXi -lm lib/libglut.a -lGL -lm -lX11 -lXrandr -lXxf86vm -lXi
+ld: lib/libglut.a(fg_gl2.c.o):(.bss+0x0):
+  multiple definition of `fghGenBuffers'; lib/libglut.a(fg_window.c.o):(.bss+0x0): first defined here
+ld: lib/libglut.a(fg_gl2.c.o):(.bss+0x8):
+  multiple definition of `fghDeleteBuffers'; lib/libglut.a(fg_window.c.o):(.bss+0x8): first defined here
+```
+
+Note: duplicate definition comes here from 'fg_gl2.h'.
+The fix is to move declaration to a 'fg_gl2.c' file.
+
+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.
