locale.cc (locale::locale(const char* __name)): Consolidate name setting.
2000-09-15 Benjamin Kosnik <bkoz@purist.soma.redhat.com>
* src/locale.cc (locale::locale(const char* __name)): Consolidate
name setting. Add checks for NULL __name pointers. Remove calls to
_S_initialize() as initial locale initialization can either be
assumed, or needs to be made consistent throughout locale
construtors.
(locale::locale(const locale& __other, const char* __name,
category __cat): Add checks for NULL name. Add checks for
assignment to self.
* src/localename.cc (locale::_Impl:: _Impl(const _Impl& __other,
const string& __name, category __cat, size_t __refs)): Set correct
name, has_name values.
* testsuite/22_locale/ctor_copy_dtor.cc (test01): More tests.
* docs/22_locale/locale.html: New file, more unfinished docs...
