        * Makefile.in (_G_config.h):  Set CC to $(CC) rather than to $(CXX),
        now that CXX defaults to g++ and CC default to gcc (when found).
        * config.shared:  Simplify CXX and CC, since they get overridden

Sun Mar 06 13:10:21 1994  H.J. Lu  (hjl@nynexst.com)

        * floatconv.c (_IO_dtoa ()): fix a small memory leak, set the
          "on_stack" field to be 0 if "result" is not NULL.

Sat Mar 05 13:18:20 1994  H.J. Lu  (hjl@nynexst.com)

        * floatconv.c (_IO_dtoa ()): if the number of digits of the
          floating point number is more than the previous one, free the
          old string and allocate a new one.
          [Minor optimization to avoid Bcopy. -PB]

Mon Jul 11 10:53:41 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * fileops.c (_IO_file_underflow):  'count' should be unsigned,
        since it contains the return value of read.  Reported by
        Teemu Torma <tot@trema.fi>.

Tue Dec 21 13:02:48 1993  H.J. Lu  (hjl@nynexst.com)

        * floatconv.c (_IO_strtod ()): make "+" and "-" as error.

Sat Jul  9 15:09:21 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        Make sure _IO_FILE::_flags is always initialized correctly, for the
        C functions (fopen, fdopen, popen), and not just the C++ functions.
        * fileops.c (_IO_file_init):  Set _flags to CLOSED_FILEBUF_FLAGS.
        * fileops.c (_IO_file_fopen):  Remove bogus assignment.
        * filebuf.cc (filebuf constructors):  Don't pass CLOSED_FILEBUF_FLAGS
        to streambuf constructor - _IO_file_init does it instead.
        * filebuf.cc (CLOSED_FILEBUF_FLAGS):  Removed.
        * iopopen.c (_IO_proc_open):  Use _IO_mask_flags.

Thu Jun 30 08:49:53 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * dbz/Makefile.in (mostlyclean): Add target.

Wed Jun 29 09:30:12 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * gen-params: Woops, can't run a C program to determine target
        characteristics.  Sigh.

Tue Jun 28 03:11:33 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * gen-params: Add _G_{,u}int{8,16,64}_t, use a short C program to
        determine what all these should be rather than trying to compare
        the MAX numbers in the shell.

Sun Jun 26 21:04:24 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * stdiostream.h, stdiostream.cc (stdiobuf::xsgetn):  Removed.
        Too hairy.  If we want to optimize it, we should do so in
        filebuf::xsgetn (or rather _IO_file_xsgetn).

        * stdiostream.h (class stdiobuf), stdiostream.cc:  Fix parameter
        and return types of virtual function to matcher base types (Oops!).
        * streamstream.cc (stdiobuf::xsgetn, stdiobuf::xsputn):
        Optimize to call fread.fwrite directly if !buffered.
        * fileops.c:  Fix comment.

Fri Jun 24 11:28:18 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * stdiostream.h (istdiostream, ostdiostream):  New classes.

        More robust final cleanup.
        * cleanup.c (_IO_register_cleanup):  Register _IO_cleanup,
        rather than _IO_flush_all.
        * filedoalloc.c: Update comment.
        * genops.c (_IO_unbuffer_all):  New.  Makes all files unbuffered.
        * genops.c (_IO_cleanup), libioP.h:  New function.  Call
        _IO_flush_all, and then _IO_unbuffer_all.  This is in case C++
        destructors try to do output *after* _IO_cleanup is called.

        Construct standard stdiobufs statically (using type punning).
        * stdstrbufs.c;  Unless _STDIO_USES_IOSTREAM declare standard
        stdiobufs (for stdin, stdout, and stderr), using type punning
        (struct _IO_fake_stdiobuf).  This avoids constructor-time problems.
        * stdstreams.cc:  Remove the declarations of the stdiobufs.
        Instead use the new (fake) ones in stdstrbufs.cc.  We no longer
        have to call ios::sync_with_stdio at constructor time.

        Preliminary support for new ANSI streambuf::uflow virtual.
        * libioP.h (struct _IO_jump_t):  Add __uflow field.
        * genops.c (_IO_default_uflow), libioP.h:  New function.
        * fileops.c (_IO_file_jumps), iopopen.c (IO_proc_jumps),
        iovfprintf.c (_IO_helper_jumps), strops.c (_IO_str_jumps),
        streambuf.cc (_IO_streambuf_jumps):  Add _IO_default_uflow.
        * genops.c (__uflow):  New function.
        (save_for_backup):  New function.  Some code shared by
        __underflow and __uflow, moved out from the former.
        (_IO_default_uflow):  New function.
        * libio.h (_IO_getc):  Call __uflow, not __underflow.

Wed Jun 22 20:22:49 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        Make sure that the vtable of a streambuf is always valid,
        which makes ios::rdbuf simpler and faster.
        * gen-params:  Add code to determine _G_VTABLE_LABEL_HAS_LENGTH,
        _G_VTABLE_LABEL_PREFIX, _G_VTABLE_LABEL_PREFIX_ID, and
        _G_USING_THUNKS, which describe how virtual function tables are named.
        * stdfiles.c (FILEBUF_LITERAL):  Moved to libioP.h.
        * libioP.h (builtinbuf_vtable):  New (complicated) declaration.
        * filebuf.cc (filebuf::__new), strstream.cc (SET_STR_JUMPS):
        Initialize vtable to builtinbuf_vtable, not NULL.
        * stdstrbufs.cc:  New file.  Same as stdfiles.c, except that
        vtable is initialized to builtinbuf_vtable, not NULL.
        * streambuf.h (ios::rdbuf):  Can now simplify/optimize, due to
        above changes.  Always, just return _strbuf.
        * builtinbuf.h, builtinbuf.cc (builtinbuf::vtable,
        builtinbuf::get_builtin_vtable):  Removed.  No longer needed.
        * streambuf.h, builtinbuf.cc (ios::_IO_fix_vtable):  No longer needed.
        Only defined #ifdef _STREAM_COMPAT, for binary compatibility.
        * Makefile.in:  Move stdfiles.o from IO_OBJECTS to STDIO_WRAP_OBJECTS.
        (IOSTREAM_OBJECT):  Add stdstrbufs.o.
        * Makefile.in (_G_config.h):  Pass $(CXXFLAGS) as part of $(CXX).

Fri Feb 11 11:08:01 1994  SBPM Marc GINGOLD (marc@david.saclay.cea.fr)

        * iovfprintf.c (helper_vfprintf): add
          hp->_IO_file_flags = _IO_MAGIC|(_IO_IS_FILEBUF+_IO_NO_READS);
        [This is needed because _IO_vfprintf checks for _IO_UNBUFFERED. -PB]
        [Actually:  don't set _IO_IS_FILEBUF. -PB]

Wed Jun 22 13:49:22 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * stdiostream.cc, stdiostream.h (stdiobuf::buffered):  New methods.

        * iofdopen.c (_IO_fdopen):  Various minor improvements.

        * iovfscanf.c:  Don't return EOF on control_failure.

Tue Dec 21 13:02:48 1993  H.J. Lu  (hjl@nynexst.com)

        * iovfscanf.c:  Enforce the sequence of the conversion specifications.

Fri Jun 17 20:57:22 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * iofdopen.c:  Use fcntl to check that requested access mode is
        compatible with existing access mode, and to change the
        O_APPEND file status flag if need be.

Thu Jun 16 17:33:50 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * streambuf.h (ios::init):  Initialize all the fields.
        This may be overkill, but the current ANSI working paper requires it.
        * streambuf.h (ios::ios):  Reimplement in terms of ios::init.
        * iostream.cc (Non-default constructors istream::istream,
        ostream::ostream, iostream::iostream):  Cannot use a mem-initializer,
        because it is ignored if initializing a derived class.  Instead,
        call ios::init.

Wed Jun 15 13:35:37 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * stdstreams.cc (ISTREAM_DEF):  Fix typo (it's a _fake_istream, not
        a _fake_ostream).  Reported by Jason Shirk <jshirk@gomez.intel.com>.

        * stdiostream.h, stdiostream.cc (stdiobuf::~stdiobuf):  New.
        Call _IO_do_flush.
        * stdiostream.cc (stdiobuf::sync):  Call _IO_do_flush rather
        than filebuf::sync (to avoid bad seeks).

        * libioP.h (_IO_do_flush):  Add missing parentheses.

Fri Jun  3 19:16:57 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * config.shared (CXXFLAGS): Remove -fno-implicit-templates.

        * iomanip.h: Add explicit external instantiations.

Wed Jun  1 14:14:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * libio.h (struct _IO_FILE_plus):  Move definition from here ...
        * libioP.h (struct _IO_FILE_plus):  ... to here.  Since this
        file is private to the implementation, we can rename the fields
        from the implementor's to the user's name anme space.
        (This avoids a lossage on SCO, whose stdio.h has a #define _file.)
        * iofdopen.c, iofopen.c, stdfiles.c:  Fix field references accordingly.
        * iopopen.c (struct_IO_proc_file):  Rename fields from
        implementor's name space to user's, and update usages.
        * streambuf.h (streambuf::_vtable):  Re-implement to not need
        struct _IO_FILE_plus.
        * strfile.h (struct _IO_strfile_): Likewise.

Wed Jun  1 13:57:48 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * config.shared (CXXFLAGS): Use -fno-implicit-templates instead of
        -fexternal-templates.

Tue May 31 08:49:28 1994  Mike Stump  (mrs@cygnus.com)

        * genops.c, iofclose.c, iofdopen.c, iofopen.c, iopopen.c: Be
        consistent about protecting #include <stdlib.h>.

        * ioputs.c: Add #include <string.h>, to avoid warning on alpha.

        * iofdopen.c: Add #include <stdlib.h>, so that malloc works on
        machines where sizeof(int) != sizeof(void *).

Mon May 30 17:26:49 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * pfstream.cc (ipfstream::ipfstream, opfstream::opfstream):
        Reverse sense of test of return value of procbuf::open.
        (It returns NULL on failure.)

        * filedoalloc.c (_IO_file_doallocate):  Remove dead code for
        USE_MALLOC_BUF.  Add code to return EOF if ALLOC_BUF fails.

Sat May 28 13:47:47 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * iomanip.cc: Explicitly instantiate smanip<int> and
        smanip<ios::fmtflags>.

Wed May 25 16:04:12 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * strfile.h:  Use __P instead of _PARAMS.

Fri May 20 11:42:17 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * libio.h: Rename _PARAMS macro to __P for better glibc and BSD
        compatibility.  (Also define _PARAMS for backwards compatibility.)
        * cleanup.c, iolibio.h, ioperror.c, iovfprintf.c, iovfscanf.c,
        libioP.h: Use __P instead of _PARAMS.
        * iostdio.h: Use __P instead of _ARGS.

        * fileops.c (_IO_file_read):  Minor stylistic tweak.  (It is
        preferable to test errno *after* the error return.)

Fri May 13 15:25:36 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * iostream.*: Add insertor and extractor for bool (just pretend
        it's an int).

Fri May 13 14:12:03 1994  Mike Stump  (mrs@cygnus.com)

        * gen-params: Check for builtin bool support.

Wed May 11 00:48:35 1994  Jason Merrill  (jason@deneb.cygnus.com)

        Make libg++ build with gcc -ansi -pedantic-errors
        * gen-params: #ifdef __STRICT_ANSI__, #define _G_NO_NRV.
        * pfstream.cc (ipfstream::ipfstream): Wrap use of variable-size
        array in #ifndef __STRICT_ANSI__.

Fri May  6 12:42:21 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * Makefile.in (VERSION):  Increase to 0.64.

        * isgetline.cc (istream::getline):  The delimiter should *not*
        be included in the gcount().

        * filedoalloc.c:  #include <stdlib.h> (If __STDC__) to get malloc.
        * iostream.h (ostream::put):  Remove overloaded versions, to match
        new working paper.  (Actually just put inside _STREAM_COMPAT, for now.)

Tue May  3 14:14:57 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * genops.c (_IO_default_finish):  Make robust when called
        multiple times on the same _IO_FILE*.  (One way this can
        happen is by the builtinbuf destructor being followed by the
        streambuf destructor.)

Mon May  2 13:55:26 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * gen-params: Actually determine wint_t rather than depending on
        cpp to provide it or defaulting to the underlying type for
        wchar_t.

Sat Apr 30 14:47:30 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * gen-params: Add _G_wint_t, allow __*_TYPE__ to override values
        at compile time, fix definition of _G_ARGS.

Fri Apr 29 16:55:37 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * libio.h: Remove #pragma interface.  (There is no implementation.)

Mon Mar 28 14:22:26 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * iostream.cc (ostream::operator<<(double)):  Add/fix support
        for printing '+' when ios::showpos is set.
        (Fixes bug reported by Doug Moore <dougm@cs.rice.edu>.)
        * iostream.cc (istream::read):  Set eofbit as well as failbit on eof.
        * iostream.cc (ostream::operator<<(int)):  Fix conversion
        to unsigned (used to lose on INT_MIN).
        * iostream.cc (ostream::operator<<(long)):  Use (unsigned long),
        rather than (unsigned) for temporary.

        * config.shared, Makefile.in:  Remove definitions and uses
        of XTRAFLAGS.  It is no longer needed, since it is
        now implied by the -B flag.

Fri Mar 25 00:31:22 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * builtinbuf.h: Add put /**/ around comment on trailing #endif.

        * Makefile.in (c++clean): Make clean in tests subdir, too.

Wed Mar 23 16:42:09 1994  Doug Evans  (dje@canuck.cygnus.com)

        * configure.in: Remove Makefile.tem before creating it.
        Needed when configuring from read-only source trees.

Wed Mar 16 14:06:42 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * stdstreams.cc:  Fix so that stdiobuf are used for cin/cout/cerr,
        unless _STDIO_USES_IOSTREAM is defined.
        * filebuf.cc (filebuf::setbuf):  Fix confusion about return
        value from _IO_file_setbuf.

Sun Mar 13 00:54:12 1994  Paul Eggert  (eggert@twinsun.com)

        * config.shared: Ensure that `all' precedes `.PHONY';
        BSDI 1.1 needs this.

Sat Mar 12 03:58:00 1994  Paul Eggert  (eggert@twinsun.com)

        * config.shared: Output a definition of INSTALL that uses
        $${rootme}, not ${rootme}.  Most `make's don't care, but BSDI
        1.1 `make' does.

Fri Mar  4 17:33:01 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * iopopen.c:  #define _POSIX_SOURCE.
        * isgetline.c (istream::getline):  Various fixes.

Thu Mar  3 17:58:20 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * iostream.cc (write_int):  Fix test for when to add initial '0'
        when ios::oct and ios::showbase are set.
        For hex, showbase adds initial 0x (or 0X) regardless of val==0.
        Bugs reported by Phil Roth <proth@cs.uiuc.edu>.

Mon Feb 21 13:18:20 1994  H.J. Lu  (hjl@nynexst.com)

        * libio.h (_IO_PENDING_OUTPUT_COUNT(_fp)): return the
        pending output count in _fp.

Fri Feb 25 09:26:57 1994  Ian Lance Taylor  (ian@cygnus.com)

        * gen-params: For HAVE_SYS_WAIT, compile dummy.c, not dummy.C.

Tue Feb 22 11:19:09 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * streambuf.h, genops.c, libioP.h:  Rename references to
        _IO_FILE fields other_gbase => _IO_save_base,
        _aux_limit => _IO_backup_base, and _other_egptr => _IO_save_end.
        * libio.h:  Remove no-longer needed macros _other_gbase,
        _aux_limit, and _other_egptr.
        * genops.c (__underflow, _IO_default_finishh, _IO_unsave_markers):
        Check _IO_save_base for NULL before FREEing it or calling
        _IO_free_backup_area.

Thu Feb 17 15:26:59 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * gen-params:  Improve deduction of _G_uint32 and _G_int32.
        Should now work for 16-bit, 32-bit, or 64-bit targets.
        * gen-params:  Check for sys/wait.h using ${CC}, since it's
        now used in a C file, not a C++ file.
        * floatconv.c:  Typedef _G_uint32_t as unsigned32, and use
        unsigned32 in place of unsigned long.  (Needed for Alpha.)

Tue Feb  8 13:40:15 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * fileops.c (_IO_file_close_it):  Simplify by using _IO_do_flush.
        * fileops.c (_IO_file_finish):  Don't call _IO_file_close_it -
        do it inline.  Call _IO_do_flush even if _IO_DELETE_DONT_CLOSE.
        * fileops.c (_IO_file_attach):  Set _IO_DELETE_DONT_CLOSE.
        * genops.c (_IO_flush_all):  Only call overflow if there is
        something to write.
        * iofclose.c (_IO_fclose):  Check that magic number is correct,
        and clear it when done.  Avoids crashing some buggy applications.
        * iogetline.c (_IO_getline):  Don't gratuitously increment old_len.
        * iogets.c (_IO_gets):  Take care to get required ANSi semantics.

Sun Feb  6 19:50:39 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * iomanip.cc: Explicitly instantiate operator<< and >>.

Fri Feb  4 12:28:22 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * config.shared (CXXFLAGS): Use -fexternal-templates.

        * iomanip.h: Uncomment #pragma interface.

Thu Jan 20 13:48:40 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        If no characters are read by fgets, ANSI C doesn't allow '\0' to
        be written to the buffer, but it is required by ANSI C++
        for istream::get and istream::getline.  Both use _IO_getline ...
        * iogetline.c (_IO_getline):  Don't write a '\0' at the end
        of the read data.  The input buffer length does not include
        space for a '\0'.
        * iofgets.c, iogets.c:  Change appropriately.
        Also check for _IO_ERR_SEEN, as required by ANSI.
        * isgetline.cc:  Update accordingly.

Mon Jan 17 13:24:26 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * Makefile.in (c++clean): Added target for compiler testing
        (i.e. make c++clean all).

Mon Jan 10 11:20:42 1994  Per Bothner  (bothner@kalessin.cygnus.com)

        * libio.h (_IO_putc):  Add parentheses.
        Patch from Rik Faith <faith@cs.unc.edu>.

Tue Jan  4 01:32:28 1993  Hongjiu Lu (hjl@nynexst.com)

        * genops.c (_IO_default_xsputn):
          (_IO_default_xsgetn):
        * ioignore.c: change "_IO_size_t count" to
          "_IO_ssize_t count".
        * iogetline.c: change "_IO_size_t len" to

        * iofwrite.c (_IO_fwrite):  Return 0 if either size or count is 0.
        (This is consistent with fread, and most implementations, but not

        * iostreamP.h (convert_to_seekflags): Use _IO_seek_set instead of

        * filedoalloc.c (_IO_file_doallocate):  Change type of couldbetty
        to int, and type of size to _IO_size_t, instead of size_t.
        (Change needed for Ultrix, which incorrectly deliberately doesn't

        as this is counter to Posix.2.
        * iopopen.c:  Chain open proc_files, and have the child close
        the ones that are open (as required by Posix.2).

        * fstream.h (fstreambase::rdbuf), strstream.h (strstreambase
        ::rdbuf):  Call ios::rdbuf() instead of getting _strbuf directly.

        * Makefile.in (_G_config.h): explicitly use $(SHELL) to run
        gen-params, since we know it is a script (we're explicitly looking
        in ${srcdir} for it) and /bin/sh might not be good enough.

Mon Nov 15 13:26:22 1993  Per Bothner  (bothner@kalessin.cygnus.com)

        * builtinbuf.cc:  Don't depend on initialization of static
        variable builtinbuf::vtable, since that might happen after
        we need it (for a static constructor).  Instead, initialize
        it when needed by inlining the code from get_builtin_vtable
        into ios::_IO_fix_vtable().

        * floatconv.c:  Avoid using #elif, which some C compilers lack.
        * iogetline.c, libioP.h:  Make char parameter be int, to avoid

        * filebuf.cc (filebuf:): Use sseekoff rather than seekoff
        (which loses if vtable pointer is NULL).

        * Makefile.in (VERSION):  Increase to 0.60.
        * Makefile.in (IO_OBJECTS):  Added iopopen.o.

        _IO_vfscanf to pass an extra NULL.
        * sbscan.cc (streambuf::vscan):  If passed an extra stream,
        set its error state (using new _IO_vfscanf parameter.

        * filedoalloc.c, fileops.c, genops.c, iogetline.c, ioignore.c,
        libio.h, libioP.h, streambuf.cc streambuf.h, strfile.h, strops.c,
        strstream.cc:  Replace macros (_base, _ebuf, _eback, _gptr, _egptr,

        * iostream.cc:  Use _IO_sputn instead of sputn.  _IO_sputn does
        not require a vtable pointer, and is also slightly faster.

        * builtinbuf.{h,cc} (builtinbuf::setbuf):  Fix return and
        parameter types.

Mon Oct 25 12:56:33 1993  Per Bothner  (bothner@kalessin.cygnus.com)
