	* streambuf.[hC]:  Add streambuf::padn() whcih emits many
	copies of the same character.
	* streambuf.h, sbufvscan.C(streambuf::vscan):  Extra optional
	(ios::iostate*) parameter, so errors/EOF can be reported back.

	have it set the error state on syntax errors or EOF.
	* streambuf.h, filebuf.C:  New method filebuf::do_write
	with the common functionality of do_flush and sputn.
	* streambuf.C (streambuf::sputn), filebuf.C (filebuf::sputn):
	Return immediately if count is not positive.
	* filebuf.C:  For simplicity, always set _S_TIED_PUT_GET
	for a filebuf, 	not just when it is read+write.

	Restart on an EINTR.
	* filebuf.C: Various fixes to handle uncommon combinations
	of read, writes, and seeks.
	* Makefile.in:  Add dtoa.?, outfloat.?.  Fix *clean rules.
	Increase version to 0;80.

Thu Jun  4 12:03:15 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* streambuf:  ios::set() is a standard ANSI method (though
	it is not in the AT&T libraries).

Wed Jun  3 17:08:53 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* streambuf.h:  Moved ios::set to _STREAM_COMPAT section.
	Added streambuf::stossc(), for AT&T compatibility.
	Changed global fmtflags type to ios::fmttype.
	* TODO:  Remove some things that have been done!
	* README:  Re-write the notes on stdio (which were written
	assuming that installing stdio was the default; that
	is not the case).

Sun May 31 14:06:16 1992  Per Bothner  (bothner@rtl.cygnus.com)

Thu May 28 13:57:19 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* iostream.C:  Don't cast to _G_va_list, since that may
	not be possible.
	* iostream.h (ostream::put):  Move inline definition
	inside class body (avoids order-of-definition problems).
	* procbuf.C (procbuf::open):  Re-set read/write flags.
	* sbufvform.C (streambuf::vform), sbufvscan.C (streambuf::vscan):
	Don't try to cast _G_va_list to va_list (not possible if
	these are structs); just use the _G_va_list parameter as if
	it were a va_list.  (This should work, according to _G_config.h).
	* streambuf.h:  Define new fmtflags type (from ANSI), and use it.

	messy code.  This should be more consistent now.
	* iostream.C (istream::ignore):  Optimize to use new
	streambuf::ignore when delim==EOF.  Also, set _gcount.
	* streambuf.h, streambuf.C:  New methods streambuf::ignore,
	streambuf::free_backup_area, streambuf::switch_to_get_mode,
	and streambuf::unsave_markers. and __adjust_column function.
	Also, various tweaks and optimizations.

	* filebuf.C (filebuf::do_flush):  Set get area pointers
	to base() (new pptr()), not old value of pptr().
	* filebuf.C:  Consistently set _flags to _S_NO_READS+_S_NO_WRITES
	when closing, and re-set old values when opening.
	* streambuf.h (streambuf):  New 2-op xsetflags method with mask.
	* streambuf.h (ios::is_open):  New definition:  Assume open
	unless both _S_NO_READS and _S_NO_WRITES are set.

Thu Apr 30 16:50:47 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* Makefile.in:  Bump to version 0.72.
	* streambuf.h:  Change streamoff and streampos to be _G_off_t,

	* streambuf.h:  Add cast to avoid warning.
	* streambuf.h, various:  Replace _S_CAN_READ _S_CAN_WRITE by
	the inverses _S_NO_READS _S_NO_WRITES:  Because these flags
	are not part of the standard streambuf protocol, we should
	infer anything if they are not set.
	* filebuf.C:  filebuf::sys_write() does multiple writes if
	needed, and updates _fb._offset (that might be a mistake).
	* filebuf.C:  Work-in-progress, to clean up various things.
	* streambuf.[hC], filebuf.C, makebuf.C:  Move shortbuf from filebuf
	class to streambuf.  New methods streambuf::doallocbuf and
	allocbuf set base() to shortbuf if unbuffered().  This
	simplifies things, since it always sets up a buffer.
	* iostream.texi:  Various improvements.
	* streambuf.[Ch]:  New virtual methods streambuf::get_column()
	and streambuf::set_column for keeping track of column in output.

Thu Apr 30 09:09:06 1992  K. Richard Pixley  (rich@cygnus.com)

	* igetsb.C (istream& istream::get(streambuf&b, char)): New function.
	* iostream.texi:  The barest beginnings of a manual.
	* streambuf.h, streambuf.C, other places:  All standard

	useful for scanning/parsing (see iostream.texi).
	* filebuf.C: Numerous bug-fixes, many from Hongjiu Lu
	<hlu@eecs.wsu.edu>.
	* filebuf.C: filebuf::pbackfail is no longer needed, since
	the logic is now handled by streambufs (rather: backupbufs).
	* iostream.h:  Add proper (signed char) support (if the
	compiler can deal with it).
	* iostream.h:  Add istream::vscan and scan methods.
	* iostream.C:  No longer need closed_streambuf dummy class
	(for non-abstarct under-/overflow); use backupbuf instead.
	* iostream.C:  Add istream& operator>>(istream&, streambuf*).
	* Various places:  Use _G_-prefixed form of parameters
	from ../_G_config.h.
	* stream.C (itoa): Make sure minus sign comes first ...

	* streambuf.C (streambuf::sgetn):  Fix logic bug.
	* strstream.C (3-argument strstreambuf::strstreambuf):
	Set ititial _len correctly.
	* stdio/fclose.C (fclose):  Don't delete stdin/stdout/stderr.

	Generate ioconfig.h automatically in the Makefile.
	* ioconfig.h:  Deleted, now automatically generated.
	* Makefile.in:  New rule to generate ioconfig.h.  Add -I. to path.

	* ioprivate.h:  Use new/delete for buffers, not malloc/free.
	* stream.C:  Remove default argument duplication (makes
	cfont happier).
	* streambuf.h:  Added protected methods to access the privately
	inherited __streambuf fields.  This should remove most of
	visibility violations (reported by a cfront user).
	* filebuf.C, strstream.C:  Use these new protected methods.

	* SFile.C, SFile.h:  New files, based on old stream-based versions.
	* Makefile.in, depend, configure.in:  Move some make rules to
	../Make.defs.  Use 'make depend.'

	(that might not work on all compilers), instead of virtual bases.
	* fstream.[hC]:  Derive fstream from iostream.
	* iostream.[hc}, PlotFile.C: Changed all operator<< and operator>>
	unary member functions into binary non-member functions.
	* streambuf.[Ch], editbuf.[Ch], indstream.[Ch]: Correct return
	type of streamuf::seekoff and ::seekpos virtual methods
	to streampos (was streamoff).
	* filebuf.C (filebuf::seekoff):  Major changes.  Now
	it should work most of the time ...
	* iostream.[Ch]:  Add seek[pg] and tell[pg] methods.
	* iostream:  Made count value for read() and write() methods
	consistently have type 'int' (until ANSI changes it to size_t)!
	* streambuf.h, iostream.C:  Replace {i,o,io}stream::close()
	methods with a 	single ios::close method (that is only enabled
	if _STREAM_COMPAT).
	* __vsbprintf.C (__cvt_double):  Fixed bug in %g format.
	* __vsbscanf.C:  Fix casts to use fully prototyped types.
	* fstream.h, iostream.[Ch], streambuf.[Ch]: Add some
	more _STREAM_COMPAT compatibilty functions.
	* strtoul.C:  Change type of variable to avoid warnings.
	* streambuf.C (streambuf::sputn, streambuf::sgetn):  Made more
	robust (don't assume that _epptr >= _pptr -- which isn't true for
	line-buffered filebufs).

	is just a "forwarding pointer" to another streambuf.
	* Makefile.in:  Add new indstream.[Ch].

	streambuf::clear(rdstate()|XX) in various places.
	* streambuf.h, streambuf.C, iostream.h, iostream.C, editbuf.C:
	Rename streambuf::xsputn and streambuf::xsgetn back to sputn
	and sgetn.  I seem to have been misled by a typo in the ANSI draft.
	* streambuf.h, filebuf.C: Add filebuf::sputn and filebuf::sgetn
	as hooks for future optimization.
	* streambuf.C (streambuf::sputn and streambuf::sgetn):
	Re-write to be more efficient.
	* streambuf.C, iostream.C:  Define the _STREAM_COMPAT macro
	before 	including ioprivate.h to force compilation of out-lined
	functions that might be needed by libg++.
	* strtoul.C:  Use 'base' in place of 'radix' variable.
	Fix in various minor ways for ANSI compliance.
	* fstream.C (open methods and constructors):  Made sure to
	set(ios::badbit) if open failed.
	* ioprivate.h:  Remove declarations of removed functions.
	* filebuf.C (filebuf::~filebuf):  Fix '=' for '=='.

Sun Jan  5 01:18:06 1992  Per Bothner  (bothner at cygnus.com)

	* Makefile.in (install_include_files):  Various fixes.

Sat Jan  4 23:44:55 1992  Per Bothner  (bothner at cygnus.com)

	* Makefile.in:  Add install-include-files rule,
	and tweak the *clean rules.
	* fstream.h, fstream.C:  Make filename parameter (in constructors
	and open() methods) be const, following ANSI,
	* streambuf.h, streambuf.C, iostream.h, iostream.C, editbuf.C,
	__vsbprintf.C, __vsbscanf.C: Rename  streambuf::xsput() -> xsputn()
	and sgetn() to xsgetn(), and make them virtual, following ANSI draft.
	* streambuf.h, streambuf.C: Add streambuf::ungetfail() (from ANSI).
	* PlotFile.h, PlotFile.C:  Quickie translations of old
	stream-based version of PlotFile class.	

Fri Jan  3 16:14:07 1992  Per Bothner  (bothner at cygnus.com)

	* Makefile.in:  List include files in three categories:
	INTERNAL_INCLUDES (private to the implementation),
	COMPAT_INCLUDES (to improve compatibility with olf stream
	library), and USER_INCLUDES (new public interface files).
	These, and the new put_io_files rule will help to a libg++
	that incorporates the iostream library.
	* stream.h:  Add _STREAM_COMPAT flag to request
	maximum compatility with old libg++ stream library.
	Add WS as a synonym for ws.
	* streambuf.h, iostream.h: Add extra junk if _STREAM_COMPAT
	flag is set (presumably by stream.h).
	* istream.h, ostream.h:  Added for compatibility with old
	libg++ stream library.
	* streambuf.h, streambuf.C, iostream.h: Add streambuf::sungetc()
	and istream::unget() (recently added to ANSI C+ library draft).

Thu Jan  2 22:51:25 1992  John Gilmore  (gnu at cygnus.com)

	* Makefile.in:  Set .SUFFIXES, and make "clean" recurse.  Ordinary
	builds do not recurse yet, FIXME, since I don't know what is
	intended here.

Tue Dec 31 16:48:38 1991  Per Bothner  (bothner at cygnus.com)

	Accumulated bug-fixes, many sugested by various net-people.
	* streambuf.h, streambuf.C:  Push data fields of ios into a new
	super-class _ios_fields.  This makes it cleaner to define
	cin/cout/cerr without duplication.
	* streambuf.h, filebuf.C, parsestream.h, parsestream.C,
	editbuf.h, editbuf.C, stdio/fseek.C:  Change use of seek_dir
	type to _seek_dir typedef, because while the correct type is
	ios::seek_dir, some compilers (including g++ version 1.xx)
	can't hack that.
	* streambuf.h (ios::setf):  Fix semantics to return complete
	old value, not just the masked part.
	* ioprivate.h, streambuf.C, filebuf.C, strstream.C, parsestream.C,
	makebuf.C:  Use new USE_MALLOC_BUF/ALLOC_BUF/FREE_BUF macros to
	control if streambuf buffers should use malloc/free or new/delete.
	For now the default is to use malloc/free, but that will change.
	* streambuf.C, filebuf.C, fstream.C, strstream.C, igetline.C,
	parsestream.C;  Removed duplicate default parameter values
	(to make cfront happy).
	* iostream.C (ios::basefield, ios::floatfield, ios::adjustfield):
	Remove duplicate (and technically illegal) static prefix.
	* iostream.C (read_int):  Fix test for when none of the
	dec/oct/hex flags are set.
	* iosteam.C (write_int):  Fix bugs.
	* iosteam.C (ws):  Set eofbit on EOF.
	* ioconfig.h, streambuf.C:  Provide more portable hook to filebuf
	vtable. (Now handles both cfront and g++.)
	* sgetline.C (streambuf::sgetline), __vsbprintf.C, __vsbscanf.C:
	Add/fix casts.
	* local.h:  Remove obsolete file.
	* editbuf.h, editbuf.C:  Change edit_mark::new_mark method to
	be edit_mark::edit_mark constructor.
	* __vsbscanf.C:  Add missing *p++ = c.
	* makebuf.C:  Re-formatted.
	* Makefile.in, configure.in:  New files, to fit into
	general libg++ configuration.
