+       * lib/argp-help.c (hol_entry_cmp): Option sorting algorithm
+       assumes the sorting is stable, while most qsort implementations
+       are not.  Use argument addresses to ensure they never compare as
+       equal.
+
+       * tests/test-argp-2.sh (usage-indent test): Fix output
+       (func_compare): Restore diff options
+       * tests/test-argp.c: Restore #include "progname.h"
