	Use owner_before instead of pointer equality.
	(directory_iterator(std::shared_ptr<_Dir>, error_code*)): Remove.
	* include/experimental/fs_path.h (operator==, operator==):
	* include/experimental/fs_path.h [!_GLIBCXX_USE_WCHAR_T]
	(path::wstring, path::generic_wstring): Disable.
	* src/filesystem/path.cc (path::_S_convert_loc)
	[!_GLIBCXX_USE_WCHAR_T]: Skip conversion.
	* src/filesystem/Makefile.am: Add cxx11_abi_sources.

	* src/filesystem/dir.cc: Define macro for new ABI.
	(native_readdir): Remove.
	(_Dir::advance): Use readdir instead of native_readdir.
	(recursive_directory_iterator(const path&, directory_options,
	error_code*)): Use swap instead of reset.
	(ErrorCode): Remove.
	(_Dir::advance): Change ErrorCode parameter to error_code*, add
	directory_options parameter and check it on error.
	(opendir): Rename to open_dir to avoid clashing with macro. Change
	ErrorCode parameter to error_code*.
	(make_shared_dir): Remove.
	(native_readdir) [_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Don't set errno.
	(directory_iterator(std::shared_ptr<_Dir>, error_code*)): Remove.
	(directory_iterator(const path&, directory_options, error_code*)):
	Pass options to _Dir::advance and create non-end iterator on error.
	(recursive_directory_iterator(const path&, directory_options,
	error_code*)): Clear error_code on ignored error, create non-end
	iterator otherwise.
	(recursive_directory_iterator::increment): Pass _M_options to
	_Dir::advance.
	(recursive_directory_iterator::pop): Likewise.
	* src/filesystem/ops.cc: Define macro for new ABI.
	(canonical) [!_GLIBCXX_USE_REALPATH]: Add alternative implementation.
	(is_dot, is_dotdot): Define new helpers.
	(create_directories): Fix error handling.
	* src/filesystem/path.cc: Define macro for new ABI.
