+Subject: [PATCH] qstat: fix build failure against gcc-10
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On gcc-10 (and gcc-9 -fno-common) build fails as:
+
+```
+gcc ... -o qstat ...
+ld: config.o:qstat/display_json.h:24:
+  multiple definition of `json_printed'; xform.o:qstat/display_json.h:24: first defined here
+ld: config.o:qstat/display_json.h:23:
+  multiple definition of `json_encoding'; xform.o:qstat/display_json.h:23: first defined here
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+https://gcc.gnu.org/PR85678.
+
+The error also happens if CFLAGS=-fno-common passed explicitly.
