+# Circumvent GCC-10 FTBFS
+### A common mistake in C is omitting extern when declaring a global variable in
+### a header file. If the header is included by several files it results in
+### multiple definitions of the same variable. In previous GCC versions this
+### error is ignored. GCC 10 defaults to -fno-common, which means a linker error
+### will now be reported.
