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.
