+Subject: [PATCH] The build fails when '-fno-common' is added to CFLAGS
+
+As reported by 'sbraz', the build stops with the error message:
+
+   (.bss+0x8): multiple definition of `program_name'
+   (.bss+0x0): multiple definition of `program_name_short'
+
+This flag will be apparently enabled by default in gcc 10.
+
+Fix this build problem by correctly referencing as extern both
+the variables in the header file.
+
