locale.cc (locale::name()): Implement.

Browse Source 
2000-09-14  Benjamin Kosnik  <bkoz@purist.soma.redhat.com>

	* src/locale.cc (locale::name()): Implement.
	(_Impl(size_t __numfacets, size_t __refs, bool __namep = false,
	string __name = "*")): Change signature.
	(locale::classic): Initialize the "C" locale as a named locale.
	* bits/localefwd.h (locale): Change _M_num_references to
	_M_references. Eliminate _M_cached_name_ok. Rename _M_cached_name
	to _M_name.
	* bits/localefwd.h: Tweaks.
	* src/localename.cc: Tweaks.
	* testsuite/22_locale/ctor_copy_dtor.cc (test01): Add tests.
	(test01): Fix.

	* bits/basic_string.h: Consistency check, change _M_state ->
	_M_references.
