* gcc-2.95.3 Released.
2000-12-10 Bernd Schmidt <bernds@redhat.com>
2000-10-16 Jakub Jelinek <jakub@redhat.com>
* iostream.cc (ostream::operator<<(double n)) [__GLIBC_MINOR__ >= 2]:
Initialize new fields wide and i18n of struct printf_info.
(ostream::operator<<(long double n)) [__GLIBC_MINOR__ >= 2]:
Likewise.
2000-09-23 Franz Sirl <Franz.Sirl-kernel@lauterbach.com>
* stdstreams.cc: Include <libio.h>, not "libio.h".
* iolibio.h: Likewise.
(_IO_pos_BAD): Use _IO_off_t instead of _IO_fpos_t.
* libio.h (_IO_USER_LOCK): Define.
1999-12-22 Jakub Jelinek <jakub@redhat.com>
* libio.h (_IO_cookie_io_functions_t): Use _IO_off_t instead of
_IO_fpos_t.
(_IO_seekoff, _IO_seekpos): Likewise. Use _IO_off64_t instead of
_IO_fpos64_t.
* libioP.h (_IO_seekoff_t, _IO_seekpos_t, _IO_seek_t): Likewise.
(_IO_seekoff, _IO_seekpos): Likewise.
(_IO_default_seekoff, _IO_default_seekpos): Likewise.
(_IO_default_seek): Likewise.
(_IO_file_seekoff, _IO_file_seek, _IO_str_seekoff): Likewise.
* streambuf.h (streampos): Typedef to _IO_off_t resp. _IO_off64_t.
* parsestream.h (class parsebuf::pos_at_line_start): Change type
to _IO_off_t.
2000-01-28 Martin v. Löwis <loewis@informatik.hu-berlin.de>
* fstream.h (ifstream::ifstream): Add ios::in to mode.
