basic_file.h (get_fileno): Remove. 

2001-03-26  Benjamin Kosnik  <bkoz@redhat.com>

	* include/bits/basic_file.h (get_fileno): Remove.
	(_M_fileno): Remove.
	(_M_cfile_created): Add.
	(basic_file::basic_file(__c_file_type*, openmode): Add.
	(basic_file::basic_file(int, const char*, openmode): Remove.
	* include/bits/fstream.tcc (basic_fstream::basic_filebuf(int __fd,
	const char*, ios_base::openmode): Don't allocate
	internal buffers. Turn off internal buffers.
	(basic_filebuf::overflow): Remove test for null buffer.
	(basic_filebuf::_M_really_overflow): Same. Allow unbuffered use.
	* include/bits/streambuf.cc: Tweak.
	* include/bits/std_ostream.h: Tweak.
	* config/basic_file_libio.h: Same.
	* config/basic_file_stdio.h: Same.
	* src/ios.cc (ios_base::Init::Init()): Unbuffer stdout by default.
	* testsuite/27_io/filebuf_members.cc: Tweaks.
	* testsuite/27_io/ios_base_members_static.cc: Tweaks.
