2001-12-14  Benjamin Kosnik  <bkoz@redhat.com>

	Clean up initialization and simplfy caching of underlying "C"

	Unconditionally create __clocale object for all named locales,
	including "C" and "POSIX".
	* config/locale/c_locale_generic.cc
	(locale::facet::_S_create_c_locale): Always set __cloc to zero.
	* config/locale/c_locale_gnu.cc: Always delete.
	* include/bits/localefwd.h (locale::facet::_S_c_locale): New.
	* src/locale.cc (locale::classic()): Initialize
	locale::facet::_S_c_locale.
	(locale::facet::_S_c_locale): Define.

	* include/bits/locale_facets.h: Add ctype_byname<wchar_t> ctor
	specialization.
	* src/locale.cc: Add definition here.
	* config/os/gnu-linux/bits/ctype_inline.h: Tweak.
	* config/os/gnu-linux/bits/ctype_noninline.h: Adjust initializations.
	* include/bits/locale_facets.h (ctype<char>::_M_c_locale_ctype): Add.
	Adjust ctors, dtors.
	(ctype<char>::_M_toupper): Remove const&.
	(ctype<char>::_M_tolower): Remove const&.
	(ctype<char>::_M_ctable): Remove const&.

	* include/bits/locale_facets.h (collate): Clean up initialization
	of _M_c_locale_collate in ctors and dtors.
	* config/locale/collate_members_gnu.cc: Always use extended
	functions.

	* include/bits/locale_facets.h (messages): Clean up inits in ctor/dtor.
	(messages_byname): Same.
	* config/locale/messages_members_generic.h (messages::~messages):
	Remove.
	* config/locale/messages_members_gnu.h: Same.

	* include/bits/localefwd.h: Clean. Move dtor definitions to
	* src/locale.cc: Here.
	* testsuite/22_locale/facet.cc: Fix spelling.

	Named locale support for ctype<wchar_t>.
        * acinclude.m4 (GLIBCPP_ENABLE_CLOCALE): Add variable
        ctype_members_* bits.
        * aclocal.m4: Regenerate.
        * configure: Regenerate.
        * src/Makefile.am (sources): Add ctype.cc.
        * src/Makefile.in: Regenerate.
