2007-01-18  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/basic_string.h (basic_string<>::_S_compare): Add.
	(compare(const basic_string&)): Use it.
	* include/bits/basic_string.tcc (compare(size_type, size_type,
	const basic_string&), compare(size_type, size_type,
	const basic_string&, size_type, size_type), compare(const _CharT*),
	compare(size_type, size_type, const _CharT*), compare(size_type,
	size_type, const _CharT*, size_type)): Likewise.
	* include/ext/vstring_util.h (__vstring_utility<>::_S_compare): Add.
	* include/ext/vstring.h (compare(const __versa_string&)): Use it.
	* include/ext/vstring.tcc (compare(size_type, size_type,
	const __versa_string&), compare(size_type, size_type,
	const __versa_string&, size_type, size_type), compare(const _CharT*),
	compare(size_type, size_type, const _CharT*), compare(size_type,
	size_type, const _CharT*, size_type)): Likewise.
