+Subject: [PATCH 2/3] Drop superfluous global variable definitions
+
+The only place where the EXTERN macro mechanism is used to define the
+global variables 'vt_outmap' and 'vt_inmap' is minicom.c (by defining
+an empty EXTERN macro and including the minicom.h header). The file
+vt100.c already defines these variables. The vt100.o object file is
+always linked to minicom.o. Thus it is safe not to define the
+variables in minicom.c and only declare them in the minicom.h header.
+
+This fixes linking with gcc 10 which uses -fno-common by default,
+disallowing multiple global variable definitions.
+
+Upstream-Status: Backport [https://salsa.debian.org/minicom-team/minicom/-/commit/c69cad5b5dda85d361a3a0c1fddc65e933f26d11]
