    * outfloat.C (__outfloat):  Interpret a precision of 999
    (e.g. %.999g) to mean "as many digits as are needed".

    * iostream.h (ios inline methods):  Restructure
    to avoid stupid cfront warnings.
    * iostream.h (istream::peek) moved to iostream.C:
    Make non-inline.  Never set failbit.  Set eofbit on EOF.
    * iostream.C (flush):  Just call ostream::flush,
    rather than poorly-defined overflow(EOF).
    * stream.h:  Define obsolete functions ::str and ::char
    here, rather than in builtin.h.
    * indstream.h (indirectbuf::lookup_stream):  Avoid cfront
    warning about unused parameter name.

Thu May  6 16:52:08 1993  Per Bothner  ([e-mail])

    * parsestream.h (parsebuf::seekoff):  Add argument default
    (seems to be needed for cfront).
    * sbufvscan.C (streambuf::vscan):  Use a new typedef (strtoulfn
    for strtoul()).  This avoids a cfront bug.
    * stdstreams.C:  Add support for cfront.

Tue Apr 27 20:31:18 1993  Per Bothner  ([e-mail])

    * iomanip.h (omanip):  Fix typo (friend operator>> to <<).

Thu Apr 22 18:42:37 1993  Per Bothner  ([e-mail])

    implementation to *before* #includes.

Tue Apr 20 19:17:55 1993  Per Bothner  ([e-mail])

    * filebuf.C (filebuf::open):  Fix for '+'-suffixed modes.
    * filebuf.C (filebuf::do_write):  Even if write fails,
    update the buffer the mark the data as out-of-here.
    * strstream.h (class strstreambuf):  A static stream is
    always frozen, and cannot be unfrozen.
    * strstream.C (strstreambuf::seekoff);  Remove dubious
    assignments to _allocate_buffer and _free_buffer.
    * stdstrbufs.C (vt_stdiobuf):  Fix mis-count.

Fri Apr 16 13:27:05 1993  Per Bothner  ([e-mail])

    * floatconv.C (dtoa):  Allocate more space for result.
    Seems to fix occasional memory smash.
    * floatconv.C:  If __386__, assume little-endian 8087-format.
    * stdiostream.C (stdiobuf::sys_write):  Fix thinko.
    * stdiostream.C (stdiobuf::sync):  Don't fseek.
    * sbufvscan.C (streambuf::vscan.C):  Format codes 'X',

Thu Jan 21 14:45:19 1993  Per Bothner  ([e-mail])

    * iostream.C (istream::operator>>(char*)):  Stop at
    width()-1 chars, not width() (to leave room for '\0').
    * iostream.C (write_int, ostream::operator<<(integral types)):
    Slight change in calling convention of write_int, to make
    sure we never print '+' for unsigned values.

Tue Jan 19 11:51:01 1993  Per Bothner  ([e-mail])

    * iomanip.h:  Minor syntax changes to enable compiling with
    cfront.  From [e-mail].

Sat Jan 16 17:27:05 1993  Per Bothner  ([e-mail])

    * iostream.C (istream::operator>>(char*)):  Don't set
    failbit is file ends in middle of non-empty string.
    * iostream.C (ostream::operator<<(char)):  Follow AT&T
    implementation (re use of width(), rather than their docs.
    * iostream (ostream::operator<<(double)):  Fix use of
    precision:  If it is 0 and not ios::fixed, use default (6).

Fri Jan 15 04:49:22 1993  Mike Stump  ([e-mail])

    * iostream.C (ends): Give 0 a char type, so as to be unambiguous.

Tue Dec 29 08:59:29 1992  Ian Lance Taylor  ([e-mail])

    * Makefile.in: pass $(FLAGS_TO_PASS) to all calls to make.

Tue Dec 22 14:12:52 1992  Per Bothner  ([e-mail])

    * streambuf.h: Don't define fpos_t (vulnerable to name clashes,
    as well as being non-standard); just use _G_pos_t.
    * streambuf.h, filebuf.C, parsestream.h, stdiostream.[hC]:
    Replace fpos_t -> _G_fpos_t.
    * Makefile.in (AR_FLAGS):  Use rc instead of non-standard qc.
    * Makefile.in (iostream.dvi):  New rule.
    * filebuf.C (filebuf::underflow):  Call switch_to_get_mode().
    * stdstrbufs.C:  Change type of _std_filebuf_[123] from
    _fake_filebuf[1] to plain _fake_filebuf, for compatibility
    with stdio/stdio.h.

Sun Dec 20 14:05:37 1992  Per Bothner  ([e-mail])

    * outfloat.C (__outfloat):  Handle cases like 10.0 correctly.
    (Fix from H.J. Lu.)

Wed Dec  9 14:48:38 1992  Per Bothner  ([e-mail])

    * streambuf.h:  #undef open and close, in case some header
    file defines these as macros.

Thu Dec  3 19:40:07 1992  Per Bothner  ([e-mail])

    * Makefile.in (distclean, realclean): Don't delete
    Makefile until *after* recursing.

Mon Nov 23 14:05:47 1992  Per Bothner  (bothner at cygnus.com)

    * filebuf.C (filebuf::open):  Fix typo ios::app -> ios::out.

Tue Nov 17 21:52:55 1992  Per Bothner  ([e-mail])

    * filebuf.C (filebuf::open):  ios::app implies ios::out.
    * igetline.C (istream::getline, istream::get):  Slightly more
    complicated to handle empty lines without setting error state.

Thu Nov  5 18:08:48 1992  Per Bothner  ([e-mail])

    * streambuf.h:  Add _S_IS_APPENDING flag.
    * filebuf.C:  Handle append mode better.  (Seek to end when
    opening. File position is unpredictable before and after a write.)
    * streambuf.h:  Fix semi-typo for value of ios:fixed.

Mon Nov  2 22:25:53 1992  Per Bothner  ([e-mail])

    * strstream.h (strstream):  Fix broken default constructor.
    * stdstrbufs.C:  Don't include unneeded <stdiostream.h>
    (which caused mips assembler to complain about a conflict).
    * stdiostream.C (stdiobuf::sync):  Don't call fflush()
    on read-only files.

Sun Nov  1 14:54:26 1992  Per Bothner  ([e-mail])

    * floatconv.C:  Renamed from dtoa.C, to avoid conflicts
    with ../src/dtoa.cc.
    * Makefile.in:  Update as appropriate.

    * filebuf.C, indstream.{h,C}, stdiostream.{h,C}, streambuf.{h,C}:
    Rename sputn/sgetn virtual methods to xsputn/xsgetn.
    Add sputn/sgetn inlined non-virtual that just call  xsputn/xsgetn.
    This change is to be compatible with ANSI and AT&T.
    * stdstrbufs.C:  Make sure all standard stdiobufs are unbuffered.

Wed Oct 21 17:48:03 1992  Per Bothner  (bothner at PersSony)

    * outfloat.C (__outfloat): If no error, return value is
    number of characters printed.
    * sbufvform.C (streambuf::vform):  Fix a number of buglets.

Tue Oct 20 15:20:17 1992  Per Bothner  ([e-mail])

    * streambuf.h, sbufvscan.C, sbufvform.C : Add streambuf::scan
    and streambuf::form.
    * sbufvform.C:  Fix handling of precision for integer formats.
    * iostream.texi: Document the various form & scan methods.

Fri Oct 16 15:42:15 1992  Per Bothner  ([e-mail])

    Many changes here and there, many to bring closer to ANSI draft.

    * streambuf.h:  Fill character is now wchar_t.
    Add some (unused) hooks for raising exceptions.
    * sbufvscan.C (streambuf::vscan):  Set error state using an
    to (ios*) parameter instead of an (ios::iostate*).
    * iostream.C:  Change usages of streambuf::vscan().
    * iostream.C:  Slightly changed interpretations of basefield.
    * iostream.h:  Add some missing methods (signed and
    unsigned char versions of put(), get(), and getline()).
    * streambuf.{ch], indstream.[Ch]:  Removed ungetfail virtual,
    following latest ANSI draft:  Use pbackfail virtual instead.
    * filebuf.C: Moved streambuf::_un_link and streambuf::_link_in
    to streambuf.C.
    * filebuf.C (filebuf::attach):  Do *not* set _S_DELETE_DONT_CLOSE
    flag, for compatibily with AT&T.
    * filebuf.C (filebuf::seekoff):  Don't move any pointers
    if mode is 0.
    * fstream.h:  Add fstreambase::setbuf() and fstreambase::is_open().
    * fstream.[Ch] (fstreambase::close):  Set failbit if close fails.
    * fstream.C (fstreambase constructors), strstream.C (various
    constructors):  Use new ios::init() method.
    * fstream.C (fstreambase::open):  Do a clear() first.

    * strstream.[hC]:  Add strsteambuf constructors with (const char*)
    buffer.  These call new method init_const(), which sets the
    _NO_WRITE flag.  New strstreambuf::pbackfail() method fails
    if _NO_WRITE flag is set.  Needed for ANSI.
    * strstream.[hC]:  Add support for user-supplied allocation
    and free routines (from ANSI).  (New methods init_static
    and init_dynamic now used by constructors.)
    * strstream.C (strstreambuf::init_static):  Try new mechanism
    for when the buffer is "assumed to continue indefinitely."

    * iostream.C, stdstrbufs.C:  Remove not_open_filebuf.
    * stdstrbufs.C: Rename _{cin,cout,cerr}_sbuf to
    __std_filebuf_{0,1,2}.  Also define __std{in,out,err}_stdiobuf
    as standard stdiobufs.  Chain all 6 standard streambufs together.
    * stdstreams.C:  Use the __std{in,out,err}_stdiobuf rather
    than __std_filebuf_{0,1,2} by default for {cin,cout,cerr}
    - unless _STDIO_USES_IOSTREAM or USE_FILEBUF are defined.
    * streambuf.h, stdstreams.C:  New function ios::sync_with_stdio
    to switch between using __std_filebuf_{0,1,2} and
    __std{in,out,err}_stdiobuf for standard streams.  This is
    normally not needed, but is provided for AT&T compatibility.

    * iomanip.h: Rename template classes to be lower-case (following
    ANSI).  Don't declare anything if _G_NO_TEMPLATES is defined in
    <_G_config.h>.  Rename DEFINE_IOMANIP_FN1 -> __DEFINE_IOMANIP_FN1.

    * stdiostream.[hC]:  Re-implement:  Make stdiobuf sub-class
    of filebuf, and use the virtual sys_ functions (e.g. sys_read)
    to call stdio function (e.g. fread).  This simpifies stdiobuf,
    and gives us filebuf features automatically.

Sun Oct 11 19:12:20 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

    * Makefile.in: make info files at 'info' time, not install-info

Thu Sep  3 16:23:00 1992  Per Bothner  ([e-mail])

    * filebuf.C:  Remove #include of <sys/file.h>.  It is not
    standard (not in Posix), and doesn't seem to be needed.

Tue Sep  1 13:10:20 1992  Per Bothner  ([e-mail])

    * filebuf.C (filebuf::sys_write):  Set error flag appropriately.
    * procbuf.C (procbuf::sys_close):  Add Posix support.
    * stdstrbufs.C: Make cerr be unbuffered.
    * iostream.h (ostream::opfx), streambuf.h (streambuf::sputc):
    Cosmetic changes; may help cfront to inline.
    * iostream.C (istream::ignore), streambuf.C (streambuf::seekmark),
    strstream.C (strstreambuf::overflow, strstreambuf::seekoff),
    parsestream.C (string_parsebuf::string_parsebuf), editbuf.C
    (edit_streambuf::seekoff), indstream.C (indirectbuf::overflow):
    Comment out default argument specifications that duplicate
    earlier definitions (to placate cfront).
    * streambuf.h, filebuf.C:  New static member filebuf::openprot
    (Non-ANSI AT&T-ism).
    * streambuf.h:  Add ios::bin enum flag, for binary I/O
    on non-Unix systems.  Unused so far.

Wed Aug 12 11:43:55 1992  Per Bothner  ([e-mail])

    * Makefile.in: 'install-info' should install iostream.info*.

Tue Aug 11 23:46:38 1992  Per Bothner  ([e-mail])

    * Makefile.in:  Bump to VERSION 0.85.

    * iostream.[hC], fstream.[hC], strstream.[hC]:  Convert to using
    multiple inheritance, with ios as a virtual base class.  I think
    this is slightly more cumbersome and inefficient, but it improves
    compatibility     with other implementation (such as AT&T), and
    will probably be required by ANSI.  (It also allows removing some
    duplicate methods.)  Also (for compatibilty), convert operator<<
    and operator>> binary functions to unary methods.
    * stdstreams.C:  Chaneg initialization using fake_?stream
    classes to match new use of virtual base classes.
    * streambuf.h:  Make ios::~ios be virtual.

    * iostream.C (ostream::operator<<(const char* S):  Allow S
    to be NULL (in which case print "(null)").
    * igetline.C:  Set eofbit when appropriate.
    * sbufvscan .C:  Remove silly optimzation that depends on
    size_t being unsigned.
    * streambuf.h (ios::ios):  Set ios::dec initially.
    * streambuf.h, filebuf.C:  Add filebuf::setbuf(), to make sure
    that get and put areas are set up (as empty start of reserve).
    * streambuf.C (streambuf::set_column):  Don't call overflow(EOF).
    * filebuf.C (filebuf::sputn):  Fix/optimizatian for
    line-buffered files.
    * Makefile.in:  Add stdiostream.?.
    Make sure 'check' makes libio.a (since 'make all' in .. does
    not), since some tests in ./test assume libio.a.
    * iostream.texi:  Add some notes on indirectbufs and
    the new stdiobufs.
    * stdiostream.[hC]:  New files.  Defines new class stdiobuf:
    A streambuf that forwards all requests to a stdio (FILE*)
    Concept follows AT&T man pages.
    * iomanip.[hC]:  Minor improvements.

Mon Jul 27 18:24:29 1992  Per Bothner  ([e-mail])

    * dtoa.C:  Rename strtod() -> _Xstrtod(), to avoid conflicts
    with strtod() versions in shared libraries.
    * ioprivate.h: #define strtod() as _Xstrtod() (for sbufvscan.C).

Wed Jul 15 21:21:38 1992  Heinrich G. Seidl  ([e-mail])

    * iomanip.h: added parametrized manipulators.
      iomanip.C: contains the functions, which are called by
      the manipulators.

Fri Jul 10 15:49:03 1992  Per Bothner  ([e-mail])

    * filebuf.C (filebuf::sys_write):  Don't use gcc-specific
    extension:  increment of a (void*) pointer.
    * igetline.C (_sb_readline):  Don't drop the last character
    of non-terminal chunks.
    * strstream.[hC]:  Remove _size, _buffer, and _frozen fields
    of a strstreambuf.  Instead, use the plethora of flags and
    fields already available in streambuf (blen(), base(), and
    _S_USER_BUF).  This makes things more consistent and simpler.
    * streambuf.h:  Add streambuf::blen() method.
    * outfloat.C (__outfloat):  Various fixes, including calculation
    of trailing_zeroes and whether to print decimal point.
    * iostream.C:  Various stylistic improvements to Mike's
    long long support:  Avoid code duplication by always using
    long long if __GNUG__ (only needed in a few places); remove
    global variable 'uppercase';  use loop to extract digits,
    rather than recursion; other optimization tweaks.

Thu Jul  2 13:59:55 1992  Mike Stump  (mrs at cygnus.com)

    * iostream.[Ch]: Implement << and >> for long long and
    unsigned long long.

Fri Jun 26 12:10:45 1992  Per Bothner  ([e-mail])

    * Makefile.in:  Increase to version 0.81.  Add a .NOEXPORT.
    * dtoa.C:  Remove some grunge.
    * iostream.h:  Add appropriate const-ness to various casts.
    * sbufvform.C, sbufvscan.C:  More const-ness fixes.
    * outfloat.C:  Different algorithm for formatting exponent.
    * parsestream.C:  Kludge to avoid warning.
    * streambuf.h:  Fix ios::operator void * to avoid
    const-ness-removing cast.
    * streambuf.C:  Kludge for Linux.

Mon Jun 22 14:45:58 1992  Per Bothner  ([e-mail])

    * sbufvform.C:  If prec is -1, use DEFPREC.

Sun Jun 21 00:33:10 1992  Per Bothner  ([e-mail])

    * streambuf.h (ios::ios):  Fix thinko.

Fri Jun 19 23:27:27 1992  Per Bothner  ([e-mail])

    * streambuf.h, iostream.[Ch]:  Remove istream/ostream/iostream
    destructors, and do the cleanup in (new) ios::~ios instead.
    Make default constructor and destructors be inline.
    * iostream.C, fstream.C:  No longer set ios::dont_close flag
    on default constructors.  In addition to being more efficient,
    this also fixes an embarassing memory leak ...
    * procbuf.C:  Remove (union wait) kludge (for NeXT).

Wed Jun 17 17:05:37 1992  Per Bothner  ([e-mail])

    * dtoa.C:  New file, derived from dtoa.h by David M. Gay
    of AT&T.  This does guaranteed accurate conversion between
    floating-pointer numbers and their string representations.
    It exports strtod() (string->double) and dtoa (double->string).
    * outfloat.C:  New file.  Exports __outfloat(), a higher-level
    interface to dtoa().
    * ioprivate.h:  Declare these new functions.
    * sbufvscan.C:  Use new strtod() to convert floats.
    * iostream.C, sbufvform.C:  Use new __outfloat function.
    * editbuf.h:  Removed spurious "inline".
    * procbuf.C (procbuf::sys_close):: Handle systems where
    the wait() argument is (union wait*).
    * streambuf.h:  Clean up confusion vbetween ios::iostate
    and ios::fmtflags types.
    * iostream.C:  Use ios::fmtflags type and new streambuf::padn
    method as appropriate.
    * 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.
    * iostream.C:  Use 3rd parameter of streambuf::vform() to
    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.
    * filebuf.C (filebuf::sys_read, filebuf::sys_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.
    * iostream.texi:  Add some information about stdio.

Fri Jun  5 13:10:59 1992  Per Bothner  ([e-mail])

    * iostream.h:  Made istream::_gcount and istream::gcount(),
    signed (_G_ssize_t), following AT&T and ANSI.
    * iostream.C:  Make istream::read() set _gcount.

Thu Jun  4 12:03:15 1992  Per Bothner  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * Makefile.in:  Increase to version 0.76.
    Use CFLAGS, not MINUS_G.  Add FLAGS_TO_PASS macro to be more
    consistent about passing flags to sub-makes.
    * filebuf.C (filebuf::open - two methods:  Set _S_TIED_PUT_GET
    flag properly.
    * filebuf.C:  Always switch to read mode, if tied and reading,
    even if c==EOF.
    * procbuf.C:  Cosmetic change.

Thu May 28 13:57:19 1992  Per Bothner  ([e-mail])

    * 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.
    * streambuf.h: #include <stdarg.h> of needed.

Thu May 14 13:13:18 1992  Per Bothner  ([e-mail])

    * Makefile.in:  Fix handling of SUBDIRS, including passing
    of working values of CC.
    * makebuf.C, filebuf.C:  Use Posix macros S_ISCHR, S_ISREG.
    * streambuf.h, streambuf.C:  Replace _FRIEND_BUG #ifdefby
    _G_FRIEND_BUG, set in _G_config.h.
    * iostream.C (write_int):  Fix thinko: && -> &.
    * iostream.h, iostream.C:  Clean up handling of skipping of
    initial white space by ipfx(0) (e.g. setting flags correctly).


Sat May  9 13:51:12 1992  Per Bothner  ([e-mail])

    * Makefile.in:  Bump version to 0.75.

    * iostream.C (ws manipulator): Set failbit on EOF.
    Also, use skip_ws function.

Wed May  6 15:48:51 1992  Per Bothner  ([e-mail])

    * streambuf.C (streambuf::setb):  Reverse test for
    when to delete _base (oops).
    * streambuf.C (__adjust_colummn):  Add missing const.

    * filebuf.C:  Clean up a number of minor bugs and
    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.

Sat May  2 16:37:27 1992  Per Bothner  ([e-mail])

    * streambuf.h, streambuf.C, filebuf.C:  Get working initial
    rough support for keep track of current column in output.
    * streambuf.C:  New function __adjust_column() used for
    the above-mentioned column support.

Fri May  1 16:57:14 1992  Per Bothner  ([e-mail])

    * 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.
    * stdstrbufs.C:  Set _S_NO_READS+_S_NO_WRITES for not_open_filebuf.

Thu Apr 30 16:50:47 1992  Per Bothner  ([e-mail])

    * Makefile.in:  Bump to version 0.72.
    * streambuf.h:  Change streamoff and streampos to be _G_off_t,
    which seems to make more sense.

    * strtoul.C:  Removed.  Not needed, now that we use libiberty.
    * filebuf.C:  Fix (and turn on) filebuf::sputn.
    * procbuf.C:  New streambuf sub-class, provides popen/pclose
    functionality for streambufs.
    * Makefile.in:  Update appropriately.
    * 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  ([e-mail])

    * Makefile.in: make CFLAGS work when passed from the command line
      to make.

Fri Apr 17 09:18:40 1992  Per Bothner  (bothner at PersSony)

    * 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
    streambuf classes inherit from backupbuf; the classes (will)
    follow a protocol allowing guaranteed backing up, which is
    useful for scanning/parsing (see iostream.texi).
    * filebuf.C: Numerous bug-fixes, many from Hongjiu Lu
    <[e-mail]>.
    * 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 ...

    * iostream.h: Add << and >> operators for manipulator
    functions that take ios arguments.
    * filebuf.C:  #include <sys/types> *before* <sys/file>.
    * filebuf.C (filebuf::close):  NULL out buffer pointers.
    indstream.C ioconfif.h iostream.C iostream.h
    * streambuf.h, streambuf.C:  Make streambuf an abstract class by
    making underflow and overflow pure virtual functions.
    * parsestream.h, sbufvform.C:  Define dummy underflow and overflow
    methods, now that streambuf is an abstract class.
    * sbufvscan.C:  Fix logic bug introduced when converting from C.
    * 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.
    * dummy.C, statdummy.c:  Small test programs used when
    generating ioconfig.h.

    take/return ints, not longs.
    * makebuf.C:  Replace test for VMS by generic NO_ST_BLKSIZE.

    * stdio/Makefile, test/Makefile:  Use new IO_RELPATH and
    IO_SRCDIR macros (useful for standalone distributions of
    iostreams without the rest of libg++).

    Add various methods to enable compilation of InterViews.
    * iostream.h, iostream.C:  Add istream::ignore method
    and iostream::iostream(streambuf* sb, ostream* tied).

    * Makefile.in:  Bump to version 0.61.
    * stream.[Ch]:  Change format arg from (char*) to (const char*).

    * fstream.h:  Fix typo __GNU_G__ -> __GNUG__.

Sat Feb  8 13:39:04 1992  Per Bothner  (bothner at cygnus.com)

    * iostream.C (ws):  This time it should work!

Fri Feb  7 11:27:13 1992  Per Bothner  (bothner at cygnus.com)

    * Makefile.in:  Bumped version number to 0.60.
    Re-write 'dist' rule to work better within libg++ source tree
    (e.g. use $(srcdir); add configure).
    * iostream.h (istream::ipfx()):  Set ios::failbit if !good().
    * iostream.C (ws):  Re-write to use ipfx1().

Tue Feb  4 16:42:15 1992  Per Bothner  (bothner at cygnus.com)

    * iostream.C (read_int):  If eof and no values,
    set eofbit as well as failbit.
    * iostream.C (ws):  On eof, set failbit as well as eofbit.

    * editbuf.[Ch]: New method edit_streambuf::set_current().
    * streambuf.h, iostream.[Ch], __vsbscanf.C, __vsbprintf.C:
    Define and use _IO_VA_LIST instead of va_list.
    (Using va_list causes namespace problems.)
    * streambuf.[Ch]:  Make streambuf::flush_all() return an int
    (for the benefit of stdio/fflush()).
    * Makefile.in:  Also make stdio.

Sat Feb  1 12:44:36 1992  Per Bothner  (bothner at cygnus.com)

    * igetline.C (istream::gets):  Set failbit if eof and no data.

    * iostream.{h,C}:  Add istream::read(void*,int) and
    ostream::write(const void*,int).  Flesh out
    istream::read(char*, int) and ostream::write(const char*,int)
    a bit, move them to iostream.C, and make the other
    overloaded variants be inline functions with casts.

Fri Jan 31 17:02:53 1992  Per Bothner  (bothner at cygnus.com)

    * filebuf.C (filebuf::close()):  _un_link() a file
    when closing it.

    * streambuf.C:  Move #pragma implementation earlier in the file.
    * Makefile.in (install-include-files):  Re-write;
    the previous form broke for some reason under Ultrix..

Wed Jan 29 12:01:58 1992  Per Bothner  (bothner at cygnus.com)

    * fvwrite.[hC]:  Removed.
    * __vsbprintf.C:  Removed __sbvwrite, __sbprint, and all
    of the struct __suio junk (from the BSD stdio implementation).
    * 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.
    * streambuf.[Ch]:  Make flush_all a static member of
    streambuf, and added streambuf::flush_all_linebuffered().
    * iostream.h:  Add struct Iostream_init for AT&T compatibility.
    * strstream.C (strstreambuf::overflow):  Minor tweaking.
    * iostream.[hC], strstream.[Ch], parsestream.[Ch], editbuf.[Ch]:

Fri Jan 24 23:53:24 1992  Per Bothner  (bothner at cygnus.com)

    * 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.'
    * iostream.[hC]:  Define an iostream class.  This uses coercions
    (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).

Thu Jan 16 17:07:46 1992  Per Bothner  (bothner at cygnus.com)

    * __vsbprintf.C, streambuf.h, iostream.C, stream.C: Change
    __vsbprintf to streambuf::vform method.
    * __vsbscanf.C, streambuf.h, iostream.C: Change __vsbscanf to
    streambuf::vscan method.
    * __vsbprintf.C, iostream.C:  Added helper class help_streambuf,
    used by new function help_vform.  This is used to give a
    temporary buffer to an unbuffered file.
    * instream.h, indstream.C:  New indirectbuf subclass of streambuf
    is just a "forwarding pointer" to another streambuf.
    * Makefile.in:  Add new indstream.[Ch].
    * iostream.C:  Use streambuf::set(XX) instead of
    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.

    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):
