* Version 5.0.90.
+ * tests/priv-check: Use `id -u' to see if we're running as root,
+ rather than trying go write to an write-protected file.
+ When running as root, ensure $NON_ROOT_USERNAME is valid.
+ When running as root with `require-non-root', ensure that `.'
+ is writable by $NON_ROOT_USERNAME, then reinvoke $0 set-user-ID
+ to $NON_ROOT_USERNAME. If `.' is not writable, then skip the test.
+
* src/printenv.c: Include "exitfail.h".
(main): Set exit_failure rather than calling close_stdout_set_status.
* src/date.c: Likewise.
