{noformat}
2008-06-03  Farid Zaripov  <farid_zaripov@epam.com>

	* include/fstream.cc (close): Zero out file pointer even when close() is
	called from detach() and all data flushed successfully.
	* tests/iostream/27.filebuf.cpp (test_ctors): Detach pfb from file pointer
	before delete because of the file is already closed in fb dtor.
	(test_attach): Close file descriptor before removing the file.
