localename.cc (locale::_Imp): Remove typedefs.

Browse Source 
2000-09-19  Benjamin Kosnik  <bkoz@purist.soma.redhat.com>

	* src/localename.cc (locale::_Imp) : Remove typedefs.
	* bits/localefwd.h (locale::locale(const locale& __other, _Facet*
	__f): Consistency check,, call _Imp ctor with refererence argument
	of 1.
	* bits/localefwd.h: Change _S_num_categories to
	_S_categories_num. Add new data member, _S_facets_num, which is
	the number of standard facets.
