An initializer-list constructor taking a non-const lvalue cannot be
called with a temporary, so the array's lifetime probably doesn't end

case.

gcc/cp/ChangeLog:

        * init.c (maybe_warn_list_ctor): Do not warn for a reference to
        a non-const std::initializer_list.

        * g++.dg/warn/Winit-list5.C: New test.



Tested x86_64-linux. OK for trunk?

OK, thanks.
