fstream.tcc (filebuf::_M_init_filebuf): Don't set _M_buf_size based on macro, instead use _M_buf_size_opt.

2000-05-08  Benjamin Kosnik  <bkoz@cygnus.com>

	* bits/fstream.tcc (filebuf::_M_init_filebuf): Don't set
	_M_buf_size based on macro, instead use _M_buf_size_opt.
	* bits/std_streambuf.h (basic_streambuf): Add _M_buf_size_opt.
	(basic_streambuf()): Set _M_buf_size_opt.
	* testsuite/27_io/filebuf.cc (filebuf): Use _M_buf_size_opt
	instead of _M_buf_size.
