ostream_manip.cc (test02): Add tests.
2000-06-29 Benjamin Kosnik <bkoz@purist.soma.redhat.com> * testsuite/27_io/ostream_manip.cc (test02): Add tests. * bits/ostream.tcc: Tweak. * bits/std_fstream.h (basic_filebuf::setbuf): Reset _M_buf_size_opt too. * bits/std_streambuf.h (basic_streambuf::~basic_streambuf): Zero out _M_buf_size_opt. * bits/std_sstream.h (basic_stringbuf::_M_init_stringbuf): Set _M_buf_size_opt out here. * bits/char_traits.h (char_traits::eos): Non standard member function, uglify to __eos. Return char_type(). * bits/std_ostream.h: Change. * testsuite/27_io/ostream_seeks.cc: New file. * testsuite/27_io/ostream_seeks-1.tst: New file. * testsuite/27_io/istream_unformatted.cc (main): Move test04 and test05 to... * testsuite/27_io/istream_seeks.cc: New file.
