codecvt_specializations_ieee_1003.1-200x.h: Initialize all data members in copy ctor.

Browse Source 
2002-01-31  Benjamin Kosnik  <bkoz@redhat.com>

	* config/locale/codecvt_specializations_ieee_1003.1-200x.h:
	Initialize all data members in copy ctor. Make ctors explicit.
	(__enc_traits::__enc_traits()): Default ctor does nothing.
	(__enc_traits::_M_init): Guard against multiple iconv_opens.
	* include/std/std_sstream.h (basic_stringbuf): Make data members
	protected.
	* include/std/std_fstream.h (basic_filebuf): Same.
	* include/std/std_streambuf.h: Tweak.
	* include/bits/streambuf.tcc: Same.
	* include/bits/sstream.tcc: Same.
	* include/bits/fstream.tcc: Same.
