|     {
|       _CharT _M_c;
|       _Char_traits_match(_CharT const& __c) : _M_c(__c) { }
| 
|       bool
|       operator()(_CharT const& __a) { return _Traits::eq(_M_c, __a); }
|     };
| 
| which, currently at least (I mean, 3.3, 3.4, and mainline), seems completely
| unused. I'm tempted to remove it from mainline: anyone objects?

OK with me.
