Subject: [PATCH] ctype_noninline.h [...]: Remove using _C_legacy::__ctype_*.

	* config/os/gnu-linux/ctype_noninline.h
	[_GLIBCPP_USE_SHADOW_HEADERS]: Remove using _C_legacy::__ctype_*.
	(ctype<char>::classic_table): If _GLIBCPP_C_LOCALE_GNU, return
	_S_c_locale->__ctype_b, otherwise temporarily switch to "C" locale
	and return __ctype_b.
	(ctype<char>::ctype(__c_locale, const mask*, bool, size_t)): If not
	_GLIBCPP_C_LOCALE_GNU, temporarily switch to "C" locale and
	initialize using __ctype_{b,tolower,toupper}.
	(ctype<char>::ctype(const mask*, bool, size_t)): If
	_GLIBCPP_C_LOCALE_GNU, initialize using
	_S_c_locale->__ctype_{b,tolower,toupper}, otherwise temporarily
	switch to "C" locale and initialize using __ctype_{b,tolower,toupper}.
