+Subject: [PATCH] gdbm: fix link failure against gcc-10
+
+Before the change on gcc-10 link failed as:
+```
+  CCLD     gdbmtool
+ld: ./libgdbmapp.a(parseopt.o):(.bss+0x8): multiple definition of `parseopt_program_args';
+  gdbmtool.o:(.data.rel.local+0x260): first defined here
+ld: ./libgdbmapp.a(parseopt.o):(.bss+0x10): multiple definition of `parseopt_program_doc';
+  gdbmtool.o:(.data.rel.local+0x268): first defined here
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+    https://gcc.gnu.org/PR85678.
+
+The fix is to avoid multiple definition and rely on
+declarations only.
