	Named locale support for ctype<char>.
	* config/locale/c_locale_gnu.h (_GLIBCPP_C_LOCALE_GNU): New.
	* config/os/gnu-linux/bits/ctype_noninline.h (ctype<char>): Add
	definitions for alternate constructor.
	* config/os/solaris/solaris2.7/bits/ctype_noninline.h (ctype): Same.
	* config/os/solaris/solaris2.6/bits/ctype_noninline.h (ctype): Same.
	* config/os/solaris/solaris2.5/bits/ctype_noninline.h (ctype): Same.
	* config/os/newlib/bits/ctype_noninline.h (ctype): Same.
	* config/os/irix/irix6.5/bits/ctype_noninline.h (ctype): Same.
	* config/os/irix/irix5.2/bits/ctype_noninline.h (ctype): Same.
	* config/os/hpux/bits/ctype_noninline.h (ctype): Same.
	* config/os/generic/bits/ctype_noninline.h (ctype): Same.
	* config/os/djgpp/bits/ctype_noninline.h (ctype): Same.

	definitions for all virtual functions. These are now explicitly
	undefined for non-required factets, ie any non-char, non-wchar_t
	instantiations.
	* src/localename.cc (locale::_Impl::_Impl(string, size_t): Named
	locales use alternate constructor for ctype facet.
	* include/bits/locale_facets.h (ctype<char>::ctype(__c_locale, const
	mask*, bool, size_t): Add.
	(ctype<wchar_t>::ctype(__c_locale, size_t): Add.
	* src/locale.cc (ctype<wchar_t>::ctype(__c_locale, size_t)): Add
	definition.

	* testsuite/22_locale/ctype_members_char.cc (test02): Add, mark
	XFAIL for non-gnu locale models.
