Andrew, I see that you've asked on gcc@gcc on June 1 about
Copyright forms.  Has anyone responded?

I ask because my patch for PR fortran/68544 walks the
gfc_derived_types list.

https://gcc.gnu.org/ml/fortran/2018-06/msg00054.html

and Thomas has approved the patch.  In my patch, I
have

+static bool
+is_dt_name (const char *name)
+{
+  gfc_dt_list *dt_list;
+
+  for (dt_list = gfc_derived_types; dt_list; dt_list = dt_list->next)
+    if (strcmp(dt_list->derived->name, name) == 0)
+      return true;
+  return false;
+}

we'll need to update this to deal with your change for a
circular linked list.
