| 	* libstdc++-v3/include/bits/std_ostream.h: Replaced usage of
| 	_Traits::_S_eos() with _CharT() as per section 17.2.2.1.3.  
| 	* libstdc++-v3/include/bits/char_traits.h: Removed non-standard
| 	methods that cannot be used elsewhere.  

This is fine for both branch and mainline.  Do you have a write access?
