+From: Jakub Jelinek <jakub at redhat dot com>
+Subject: [PATCH] Set TREE_READONLY const POD arrays with size determined from initializer (PR c++/21454)
+
+This is a fallout of the PR c++/20073 fix.
+For arrays like:
+const int a[] = { 0, 1, 2, 3 };
+when cp_apply_type_quals_to_decl is called, its type is not complete yet,
+so C++ frontend does not set TREE_READONLY flag.  But such variables
+aren't put into incomplete_vars chain either, so nothing sets the flag
+afterwards.
