Paolo Carlini e3c0c0989b re PR libstdc++/13341 (ctype<wchar_t>::do_narrow(wchar_t, char) is slow) 
2003-12-12  Paolo Carlini  <pcarlini@suse.de>
	    Benjamin Kosnik  <bkoz@redhat.com>

	PR libstdc++/13341
	* include/bits/locale_facets.h (ctype<wchar_t>): Declare
	_M_initialize_ctype() and _M_narrow_ok, _M_narrow and _M_widen.
	* src/ctype.cc (ctype<wchar_t>::ctype(size_t),
	ctype<wchar_t>::ctype(__c_locale, size_t)): Use
	_M_initialize_ctype to fill _M_narrow and _M_widen.
	(ctype_byname<wchar_t>::ctype_byname(const char*, size_t)):
	Likewise.
	* config/locale/generic/ctype_members.cc (do_narrow, do_widen)
	Use _M_narrow and _M_widen when possible, instead of calling
	wctob and btowc, respectively.
	(_M_initialize_ctype): Define, it fills at construction time
	_M_narrow and _M_widen.
	* config/locale/gnu/ctype_members.cc: Likewise.
	* testsuite/performance/narrow_widen_wchar_t.cc: New.
