+# The toplevel makefile overrides $(CC) (in EXTRA_HOST_FLAGS) by setting
+# it to whatever CC was in the toplevel configure.  This breaks in Gnulib with
+# older GCCs, because Gnulib's configure uses this variable to store the
+# standard-setting switch (e.g. -std=gnu99/-std=gnu11).  To fix this, we just
+# set MAKEOVERRIDES to empty here so that import/ uses the right $(CC).
