See, e.g., how STRING_CST is handled in expand_expr_real_1.

protect_from_queue is no longer used. On the other hand, you didn't
mention which version you are using, and I don't see that comment in
the current sources. So if you are using a version which still uses
protect_from_queue, just grep for it in the source code.
