+Subject: [PATCH 3/3] Drop superfluous global variable definitions
+
+The only place where the EXTERN macro mechanism is used to define the
+global variables 'portfd_is_socket', 'portfd_is_connected' and
+'portfd_sock_addr' is minicom.c (by defining an empty EXTERN macro and
+including the minicom.h header). The source file sysdep1_s.c already
+defines these variables. The sysdep1_s.o object file is always linked
+to minicom.o. Thus it is safe to drop the definitions from minicom.c
+and only declare the variables in the minicom.h header.
+
+This fixes linking with gcc 10 which uses -fno-common by default,
+disallowing multiple global variable definitions.
