    isysdep_work_time), work.c (fswork_file, fsysdep_get_work,
    zsysdep_jobid, bsgrade): Marc Unangst, Brian Murrell: Corrected
    support for SPOOLDIR_SVR4, since SVR4 doesn't use grades in file
    names.  Changed flocal argument to pseq argument in
    zsysdep_spool_file_name, and changed flocal argument to bgrade
    argument in zfind_file.  Added fxqt argument to
    zsysdep_data_file_name.  Added bsgrade function.  Added bgrade
    argument to zsfile_to_jobid, and pbgrade argument to
    zsjobid_to_file.

Sat Oct  3 11:03:13 1992  Ian Lance Taylor  ([e-mail])

    * MANIFEST, Makefile.in, lib/MANIFEST, lib/Makefile.in,
    lib/parse.c: moved parse.c from main directory to lib.

    * system.h, unix/size.c, unix/Makefile.in, unix/MANIFEST: moved

    not exist or -2 on other errors.
    uustat.c (fsworkfile_show): handle errors from csysdep_size.
    send.c (flocal_send_file_init): handle errors from csysdep_size,

    * trans.h, uucico.c (fdo_call, faccept_call), parse.c
    (fparse_cmd), send.c (flocal_send_request): Gert Doering: SVR4
    UUCP uses a dummy string between the notify field and the size,
    for some reason.

    * tstuu.c (main, uprepare_test): added -n switch to not destroy
    existing configuration files.

Fri Sep 25 00:16:35 1992  Ian Lance Taylor  ([e-mail])

    * protg.c (fgsenddata): T. William Wells: clear bytes correctly so
    that resending a packet doesn't get a completely incorrect size.

    * send.c (usadd_exec_line): Stephen J. Walick: don't send trailing
    spaces on the created execute file, because it confuses Waffle.

Thu Sep 24 00:25:18 1992  Ian Lance Taylor  ([e-mail])

    * unix/jobid.c (zsjobid_to_file): Franc,ois Pinard: if the job ID
    is too short, return NULL rather than dumping core.
    unix/statsb.c (fskill_or_rejuv, isysdep_work_time): handle a NULL
    return from zsjobid_to_file.

Mon Sep 21 09:01:02 1992  Ian Lance Taylor  ([e-mail])

    * uuconf/init.c, uuconf/syssub.c: Lele Gaifax: moved
    declaration of _uuconf_unset from syssub.c to addstr.c because
    NeXT linker does not pull in object files solely because of
    variable declarations.

    * sysh.unx: Lele Gaifax: typo in ftw declaration.

    * lib/Makefile.in, unix/Makefile.in: Lele Gaifax: bug in clean
    target.

    to make fewer system calls.

    * send.c (fsend_exec_file_init, fsend_exec_file): handle separate
    E file correctly, and make a good statistics file entry for it.

    * Makefile.in, unix/Makefile.in, uuconf/Makefile.in,
    lib/Makefile.in: use -I flags to permit compilation in a separate
    directory.  Set up clean targets per GNU standards.

Tue Sep 15 00:07:09 1992  Ian Lance Taylor  ([e-mail])

    * uucico.c (zget_uucp_cmd): can't set size_t variable to -1.

    (flocal_send_request), rec.c (flocal_rec_send_request) parse.c
    (fparse_cmd): send file size in hex for SVR4 compatibility.
    Required new FEATURE_V103 for 1.03 backward compatibility, since
    1.03 requires decimal size.

    * various: eliminated remaining calls to alloca.

    * tcp.c (ftcp_open), tli.c (ftli_open): set FD_CLOEXEC for sockets
    and TLI descriptors.

    * tcp.c (ftcp_open): switch to real user ID before binding the
    socket when running as a server.  This will permit uucico invoked
    by root to open privileged TCP ports.  Don't switch to real ID if
    effective ID is already root, to permit an suid root program to be
    invoked by anybody.

    * uuxqt.c (uqdo_xqt_file): removed special case for system which
    does not permit any commands: unnecessary and unusual.

    * uucico.c (fconn_call): Ed Carp: clear the SIGHUP signal
    indication before opening the modem.

    * trans.h, trans.c (fqueue, fcheck_queue, floop, fgot_data),
    send.c (fsend_await_confirm), rec.c (frec_file_send_confirm),
    uucico.c (fcall, faccept_call): recheck the work queue every 10
    minutes.  Honor CYM from the remote system.  Send CYM if we have
    something to do.

Sat Sep 12 15:47:52 1992  Ian Lance Taylor  ([e-mail])

    (main), uustat.c (main), cu.c (main), uuname.c (main), unix/init.c
    (usysdep_initialize): added INIT_SUID, for old systems which don't
    do setuid correctly for root.

    * cu.c, unix/cusub.c: various minor improvements.

Sun Sep  6 20:25:20 1992  Ian Lance Taylor  ([e-mail])

    (zsysdep_xqt_local_file): Jarmo Raiha: expand ~name in uuxqt.c.

    * send.c (fremote_rec_reply): SVR4 sends the size of the file with
    the RY string, so we do too.  We don't look for it, though.

    * uustat.c, uustat.1: Don Phillips: removed all printing of years
    and seconds.  Hope nobody complains.

    * uucico.c (fdo_call): don't set the status to TALKING until we
    see the Shere string.

    * configure.in, conf.h.in, unix/wldcrd.c: if the system has glob,
    use it for wildcards.  If it doesn't, quote special characters in
    the wildcard string.

    * uucico.c (fdo_call): Zacharias Beckman: don't report ``Login
    successful'' until we see the Shere string.

    * prot.c (fsend_data): Don Lewis: bug in crec calculation.

    scripts.

    * system.h, parse.c, trans.c (fqueue, flocal_poll_file), uustat.c
    (fsworkfiles_system, fsquery_system), unix/work.c
    (fsysdep_get_work, fsysdep_get_work_init): don't delete poll files
    immediately, but instead return a 'P' command and delete them when
    the command is passed to fsysdep_did_work.

    * tstuu.c (uprepare_test): change ``call-request'' to ``request''.

    * uuconf/iniglb.c (_uuconf_itimetable): return CMDTABRET_KEEP so
    we don't lose the timetable name and definition.

    specify the file base name in the TO argument.

    * uucico.c (main): Don Lewis: don't exit with success just because
    we were able to start uuxqt.

    * unix/serial.c (fsmodem_close, fsserial_read): always drop DTR
    when closing a modem connection.  Also, retry if we time out when
    setting MIN.

Sat Aug 22 22:31:34 1992  Ian Lance Taylor  ([e-mail])

    * uuconf/time.c: Stephen Walick: don't require a comma between
    time strings, since HDB doesn't seem to.

    * protg.c (fgcheck_errors): added "error-decay" protocol parameter
    to decay errors as packets are successfully received.

    * uustat.c (fsmachines), uustat.1: Chris Lewis: don't display the
    year or seconds for uustat -m.  Probably uustat -q should be
    changed as well.

    * tstuu.c: Larry Fahnoe: don't report EWOULDBLOCK errors when
    writing to a pty.  Also removed functions which are now in lib.

    * MANIFEST, Makefile.in, uusched.in: added a simple uusched shell
    script.

    * parse.c: Heiko Rupp: don't die if there is trailing garbage in

    * log.c (ustats): Scott Blachowicz: avoid overflow when reporting
    bytes per second.

    * unix/lock.c (fsdo_lock): Chip Salzenberg: sometimes other
    programs create lock files that uucp can't write.

    * trans.h, system.h, trans.c (floop, fgot_data, usent_receive_ack,
    uwindow_acked), send.c (flocal_send_await_reply,
    flocal_send_fail), rec.c (fremote_send_fail_send,

    * proti.c (firesend, fisenddata, ficheck_errors): made several
    changes to improve performance on a lossy line: can now shrink
    packet size using SYNC packets, avoids multiple bad header errors
    in a sequence of INTRO characters, avoids letting one side lock up
    if a NAK is lost.

    * configure.in: set HAVE_LONG_FILE_NAMES to 0 if
    cross-configuring.

    * tstuu.c: changed -p option to be mod 1000, not mod 100.

    * MANIFEST, Makefile.in, prot.h, uucico.c, protz.c, trans.c: Doug
    Evans: added Doug Evans's zmodem implementation as protocol 'a'.

Wed Aug  5 22:28:14 1992  Ian Lance Taylor  ([e-mail])

    * policy.h, uuconf.h, uucico.c (fcall), uuconf/tsinfo.c,
    uuconf/hsinfo.c, uuconf/syssub.c: added "max-retries" command for

    work directory.

    * configure.in, sysh.unx: don't run any programs in configure if
    we are cross-configuring; this applies to HAVE_FTIME and
    HAVE_RESTARTABLE_SYSCALLS.  The code can cope with the buggy
    ftime.  If we are cross-configuring, HAVE_RESTARTABLE_SYSCALLS is
    set to -1, and sysh.unx guesses that if the system has sigvec but
    not sigaction or SV_INTERRUPT it is on 4.2BSD and system calls are
    automatically restarted.

    * configure.in, conf.h.in, tstuu.c, unix/serial.c: removed
    COMBINED_UNBLOCK configuration parameter, and changed the code
    which sets O_NONBLOCK and O_NDELAY to drop back to using just
    O_NONBLOCK if it gets an EINVAL error.

    * configure.in, conf.h.in, uucp.h, protg.c (fgsenddata), cu.c
    (icutake), chat.c (icexpect), lib/MANIFEST: removed all calls to

    * uucp.h, uudefs.h, many other files: broke part of uucp.h out
    into uudefs.h, stopped including uuconf.h in uucp.h, fixed up .c
    files to include uudefs.h and uuconf.h as necessary.

    * uuconf/syshdr.unx, uuconf/callin.c, uuconf/diacod.c
    uuconf/hdial.c, uuconf/hdnams.c, uuconf/hport.c, uuconf/hsinfo.c,
    uuconf/hsnams.c uuconf/rdlocs.c, uuconf/tcalou.c, uuconf/tdial.c,
    uuconf/tdnams.c, uuconf/tport.c, uuconf/vport.c, uuconf/vsinfo.c,
    uuconf/vsnams.c: changed uuconf library to not return an error if
    a configuration file does not exist; it now acts as though
    whatever it is is not found.

    * tstuu.c (main): use perror if execl fails.

    * configure.in, conf.h.in, uucp.h, uuconf.h, sysh.unx, conn.h,
    MANIFEST, Makefile.in, tli.c, chat.c (ccescape), conn.c
    (fconn_init), tcp.c, uucico.c (faccept_call), uuconv.c, uuchk.c,
    lib/MANIFEST, lib/Makefile.in, lib/escape.c, unix/cusub.c,
    unix/serial.c, uuconf/hport.c, uuconf/tportc.c: added support for
    TLI connections.  Moved ccescape from chat.c to cescape in
    lib/escape.c.  Made all connections on Unix use the same
    system dependent structure.

Tue Jul 21 22:08:10 1992  Ian Lance Taylor  ([e-mail])

    * uucp.h, trans.h, uucico.c (fdo_call, faccept_call), uuxqt.c
    (uqdo_xqt_file), uucp.c (main), uux.c (main), uustat.c
    (fsworkfile_show), parse.c (fparse_cmd), trans.c (fqueue,
    fgot_data, ftadd_cmd), send.c, rec.c, xcmd.c, protf.c
    (ffprocess_data), proti.c (fiprocess_data), tstuu.c
    (uprepare_tests), unix/splcmd.c (zsysdep_spool_commands),
    unix/statsb.c (fskill_or_rejuv), unix/work.c (fsysdep_get_work):
    added E request to send file executions which only require reading
    from standard input.

    rec.c, xcmd.c, unix/opensr.c: added 'i' protocol.  Added local and
    remote channel arguments to protocol sendcmd and senddata entry
    points.  Cleaned up send and receive state machines.  Removed
    pfgone argument from esysdep_open_send.

Fri Jul 17 09:41:05 1992  Ian Lance Taylor  ([e-mail])

    * uuxqt.c (uqdo_xqt_file): only report base name of execution
    file, not full name.

    * lib/crc.c: unroll the loop a bit.

    * configure.in, conf.h.in, unix/init.c: updated to autoconf 0.120.

Wed Jul 15 14:45:32 1992  Ian Lance Taylor  ([e-mail])

    * uuconf.h, uuconv.c, uuconf/uucnfi.h, uuconf/reliab.c,
    uuconf/tportc.c, uuconf/tdialc.c, uuconf/diasub.c, uuconf/hport.c,
    uuconf/prtsub.c, uuconf/vsinfo.c: added UUCONF_RELIABLE_FULLDUPLEX

    confuses the NeXT, so instead we just call TIOCNOTTY on 0.  In
    fsserial_close we call TIOCNOTTY on the port before closing it, to
    make sure that we have ditched it under BSD.  Also added O_NOCTTY
    to every open call other than opening a port, although there are

    Chip Salzenberg: don't log a SIGHUP signal while we're closing
    down the connection, since the other side might hang up faster
    than we do (we still react to it correctly, we just don't put it
    in the log file).

    update the process ID we log after a fork.

    fsysdep_privileged function.

Thu May 21 13:30:21 1992  Ian Lance Taylor  ([e-mail])

    * uuxqt.c (uqdo_xqt_file): processing of execution file has to be
    case significant; this will change handling of "n" flag, which was
    not correctly handled before.

    expression.

    * chat.c (fcsend): simplified expression for old compilers.

    starts, perhaps because the file was too large, remember to remove
    the temporary file.

    fsserial_io): always block and unblock the read and write
    descriptors together.

    * uustat.c: allow multiple systems and users to be specified at
    once; likewise for kills and rejuvenates.  Allow old and young to
    be combined with systems and users.  As suggested by Niels
    Baggesen, make machine status output more columnar.

    * uucp.h, uucico.c, config.c, sys3.unx: Michael I Bushnell:
    renamed enum tstatus to tstatus_type to avoid conflict with
    <sys/ioctl.h> on some systems.

    strings correctly.

    * uucico.c (main, fcall): Petri Helenius: must dump controlling

    freed up.

    * uucp.h, uucico.c (fdo_call), sysinf.c (tialternate), uuchk.c
    (ukshow): Franc,ois Pinard: allow a name to be given to an
    alternate, and display the name when placing a call.

    * chat.c (fcprogram), port.c (fport_open, fport_close): David J.
    MacKenzie: send port device rather than port name to a chat
    program using \Y; make sure port device is reset if port open
    fails and when port is closed.

    * uucico.c (fuucp), log.c (ulog, ustats, ustats_close): close log
    and statistics file every time master and slave switch roles.

    Changed default newconfigdir definition.  Supported compilation in
    a different directory.  Used symbolic links if available.  Changed
    default infordir definition per Franc,ois Pinard.

    * policy.h: David J. MacKenzie: various cleanups.

Thu Mar 26 12:17:41 1992  Ian Lance Taylor  ([e-mail])

    * sys3.unx: reduced race condition in fsdo_lock.

    * sys1.unx: Gerben Wierda: various cleanups.  Also don't set
    sa_flags to SV_INTERRUPT per Chip Salzenberg.

Wed Mar 25 22:20:24 1992  Ian Lance Taylor  ([e-mail])

    * configure.in: Overhauled for readability and functionality as

    * sys1.unx (usysdep_detach): open the controlling terminal in non
    delay mode since it might be a modem.

Tue Mar 17 00:01:53 1992  Ian Lance Taylor  ([e-mail])

    * uucico.c (fdo_call, faccept_call): T. William Wells: set current
    time in status file when call completes.

    * sys1.unx (iswait), sys2.unx (fsserial_read, fsserial_write,
    fsserial_io): log signals when they occur, even if we continue
    some sort of loop, rather than waiting for the next ulog call.

    * sys2.unx (fsserial_lock, fsserial_open): don't block when
    opening the write descriptor.

Mon Mar 16 00:14:43 1992  Ian Lance Taylor  ([e-mail])

    * system.h, uuxqt.c (uqdo_xqt_file), sys5.unx (fsysdep_execute):

    * getopt.h, getopt.c: get new versions from glibc 1.01.

    * sys1.unx: don't declare sigemptyset.

    * version.c: updated to beta 1.03.

    * chat.c (fcsend): Scott Ballantyne: go ahead and send a character
    for an illegal escape sequence rather than failing out.

    * uuxqt.c (uqdo_xqt_file), sys5.unx (zsysdep_find_command): cast
    result of alloca.

    * protg.c (fgprocess_data): Niels Baggesen: improved debugging

    find the next DLE rather than searching for it by hand.

    * uucico.c (faccept_call, fuucp): accept SVR4 -U flag giving
    maximum file transfer size; accept and ignore SVR4 -R flag meaning
    that the system supports file restart.

Sun Mar 15 00:21:56 1992  Ian Lance Taylor  ([e-mail])

    * sysinf.c (titime, titimegrade): permit a retry time to be
    specified as an optional additional argument.

    script debugging.

    * sysh.unx, sys2.unx (fsserial_lock, fsserial_open,
    fsserial_write, fsserial_io, fsysdep_tcp_read, fsysdep_tcp_write,
    fsysdep_tcp_io): T. William Wells: some systems don't support
    unblocked writes, so don't use them.

    fport_write under DEBUG_PORT.

    * bnu.c (fbnu_find_port): Scott Ballantyne: accept "Any" as a
    Device speed.

Sat Mar 14 20:52:11 1992  Ian Lance Taylor  ([e-mail])

    uuxqt.c (main), uucp.c (main), uux.c (main, uxcopy_stdin), tcp.c
    (ftcp_open), log.c (ulog, ulog_close), sys1.unx (ussignal),
    sys2.unx (fsserial_close, fsysdep_modem_end_dial, fsserial_read,
    fsserial_write, fsserial_io, fsysdep_tcp_read, fsysdep_tcp_write,
    fsysdep_tcp_io): T. William Wells and Chip Salzenberg: keep an
    array of signals so that a new signal doesn't obliterate our
    knowledge of an old signal.  Johan Vromans: if we get SIGINT
    continue the current session but don't start any new ones.

    * sysh.unx, sys1.unx (isspawn, espopen, iswait, fsysdep_mail,
    fsysdep_run, getcwd, mkdir), sys2.unx (fsrun_chat), sys3.unx
    (fsysdep_wildcard_start), sys5.unx (fsysdep_execute), sys7.unx
    (fsysdep_lock_status), uuxqt.c (uqdo_xqt_file), tcp.c (ftcp_open),
    tstuu.c (uchild): added function isspawn, espopen and iswait and
    channeled all execs of new processes and waits through them.

Fri Mar 13 18:00:04 1992  Ian Lance Taylor  ([e-mail])

    * sysinf.c (uset_system_defaults): Chip Salzenberg: changed
    default login script timeout to 10 seconds.

    * prot.h, prot.c (freceive_data, breceive_char), protg.c, protf.c,
    prott.c, prote.c: changed breceive_char to go through
    freceive_data rather than calling fport_read directly.  Added an
    freport argument to freceive_data, and change all old calls to
    pass it in as FALSE.

Thu Mar 12 14:49:59 1992  Ian Lance Taylor  ([e-mail])

    * uucp.h: added a padding byte to scmd structure, since at least
    one compiler needs it.

    * uucp.c (main): use fake local name (from ``myname'' command)
    when generating an execution request intended for the local
    system.

    * sysh.unx: corrected readdir prototype.

    * sys2.unx: moved local header files ahead of sleep routine
    determination.

    * General overhaul to change debugging system.  Debugging is now
    done by type rather than by number.  iDebug is now interpreted as
    a bit sequence.  DEBUG may only be 0 (no checks or debugging), 1
    (checks, no debugging) or 2 (checks and debugging).  The debugging
    names are parsed by idebug_parse and tidebug_parse in config.c.
    The debugging types are additive.  Many source files changed.
    Inspired by Michael Richardson, Johan Vromans and Peter da Silva.

Wed Mar 11 12:01:03 1992  Ian Lance Taylor  ([e-mail])

    * policy.h, uuxqt.c (uqdo_xqt_file): Chip Salzenberg: support
    Internet mail addresses in uuxqt replies (added configuration
    parameter HAVE_INTERNET_MAIL to control this).

    * uucp.h, system.h, sysh.unx, config.c, uuxqt.c (main, uqabort),
    sys5.unx (isysdep_lock_uuxqt, fsysdep_unlock_uuxqt), bnu.c
    (ubnu_read_sysfiles): Marty Shannon: added max-uuxqts command,
    along with support for BNU Maxuuxqts, to limit number of
    concurrent uuxqt processes.

    * chat.c (icexpect, fcsend), uucico.c (zget_uucp_cmd,
    zget_typed_line): improved debugging by avoiding incredibly long
    lines.

    * system.h, sys5.unx (fsysdep_execute), uuxqt.c (uqdo_xqt_file):
    Jon Zeef: if a temporary failure occurs, retry the execution
    later.

Tue Mar 10 12:40:30 1992  Ian Lance Taylor  ([e-mail])

    * sysh.unx, sys1.unx (isfork), sys2.unx, sys5.unx, tcp.c:
    Franc,ois Pinard: retry fork several times before giving up.

    * uucp.h, prot.c (fploop, fgot_data), file.c (usendfile_error,
    urecfile_error, frecfile_rewind): Niels Baggesen: if we can't read
    or write a file, treat it as a temporary error rather than a
    permanent error; if we get an error on write, drop the connection
    rather they try to continue.

    * uucp.h, system.h, sysh.unx, uucico.c (fuucp), prot.c
    (fsend_file, freceive_file), file.c (fsent_file, usendfile_error,
    freceived_file, urecfile_error, fmail_transfer), sys1.unx
    (usmake_spool_dir), sys4.unx (zsysdep_save_temp_file): if a file
    send fails, save the file away rather than lose it forever.

    * uucico.c (main): don't run uuxqt if we got a SIGTERM.

    * tcp.c (ftcp_open): Petri Helenius: have server fork twice to
    avoid zombies.

    * port.h, prtinf.c, v2.c, bnu.c (fbnu_find_port), uucico.c
    (fdo_call, faccept_call), uuchk.c (fkshow_port): added protocol
    command for ports, mostly to support BNU.  Also modified uuchk to
    make the absence of any matching port or dialer more obvious.

    * sys3.unx (esysdep_open_receive): check size of destination file
    system as well as temporary file system; handle f_bsize field
    under FS_MNTENT.

    * configure.in, sysh.unx: test for including <termios.h> and
    <sys/ioctl.h> in the same file, setting new configuration
    parameter HAVE_TERMIOS_AND_SYS_IOCTL_H accordingly; handle it in
    sysh.unx.

Mon Mar  9 00:06:12 1992  Ian Lance Taylor  ([e-mail])

    * sys2.unx (fsserial_close): Franc,ois Pinard: sleep for a second
    after closing the serial port to give it a chance to settle.

    * sysh.unx (fsetterminfodrain), sys2.unx (fsserial_close,
    fsserial_reset, fsserial_set): wait for terminal output to drain
    before closing it, resetting it, or changing its parameters.

    * uucico.c (zget_uucp_cmd): Ted Lindgreen: strip parity bit from
    initial handshake strings.

    * system.h, sys3.unx (esysdep_open_send), uucico.c (fuucp): Ted
    Lindgreen: don't send a mail message if a file to send has been
    removed, since it might have been sent in a previous session.

    * uuchk.c (ukshow): Zacharias Beckman: put list of permitted
    programs and execution path on separate lines.

    * uucico.c (fdo_call, faccept_call): only look for hangup string
    in debugging mode, since there's nothing to be done with it
    anyhow.

    * uucico.c (faccept_call): Ted Lindgreen: report the minimum
    transfer grade requested during an incoming call in the log file.

    * uucp.h, uutime.h, config.c, uucico.c (fcall), time.c
    (ftimespan_match, btimegrade, cmax_size_now): added a new status
    type for ``wrong time to call''.  If a system can never be called,
    this status type is not used (if an attempt is made to call the
    system, the status is left unchanged).

Sun Mar  8 11:41:45 1992  Ian Lance Taylor  ([e-mail])

    * uucico.c (main, flogin_prompt, faccept_call): Ted Lindgreen: if
    we were asked to call a single system, or if a single system
    called in, then start uuxqt with -s for just that system.

    * uucico.c (main): Ted Lindgreen: ignore the -u option.

    * tstuu.c: Ted Lindgreen: don't include <sys/ioct.h> if it's not
    there.  Also removed the ``ignore this error'' message from the
    chat scripts since it's no longer marked as an error.

    * sys2.unx (fsserial_set): Ted Lindgreen: if CRTSCTS is defined
    and turned on, then don't turn on IXOFF.

    * uucp.h, log.c, uucico.c (fdo_call, faccept_call): Ted Lindgreen:
    report the port name and (for incoming calls) the login name in
    the log file.

Sat Mar  7 10:00:47 1992  Ian Lance Taylor  ([e-mail])

    * port.h, prtinf.c, sys2.unx (fsserial_lockfile, fsserial_lock):
    Peter da Silva: added ``lockname'' command to ports to permit
    specification of the file name to use when locking.

    * sys1.unx (usysdep_detach): let setpgrp fail silently.

    * sys2.unx: always include <sys/ioctl.h> if it's present on the
    system.

    * time.c (btimegrade, cmax_size_now): removed extraneous
    semicolons.

    * sys2.unx (fsserial_lock, fsserial_open, fsserial_close): support
    TIOCEXCL locking.

    * sys2.unx (fsserial_open): preserve unknown bits in c_cflag when
    using HAVE_SYSV_TERMIO or HAVE_POSIX_TERMIOS.

    * prot.h: never included more than once.

Fri Mar  6 21:53:28 1992  Ian Lance Taylor  ([e-mail])

    * uucp.h: Eric Ziegast: some systems don't define EXIT_SUCCESS or
    EXIT_FAILURE in stdlib.h.

    * uucp.h, uutime.h, uucico.c (fuucp), sysinf.c (uinittimetables,
    uaddtimetable), uuchk.c (main, ukshow_size, ukshow_time,
    qcompress_span), time.c (all new): rewrote time routines
    completely for consistency and simplicity.  Fixed bug causing
    incorrect maximum possible transfer size.  Added new file
    uutime.h.

Wed Mar  4 10:06:13 1992  Ian Lance Taylor  ([e-mail])

    * sys2.unx (fsserial_lockfile, fsserial_lock, fsysdep_modem_open,
    fsysdep_direct_open, fsysdep_modem_close, fsysdep_direct_close):
    Petri Helenius: if the open failed on a serial port, the lock
    files were not removed.

    * config.c (igradecmp): the local variables in igradecmp have to
    be integers; signed characters might not work correctly (although
    they would in all normal cases).

    * sys4.unx (fsysdep_has_work): Johan Vromans: set *pbgrade
    correctly if we still have work left over that we haven't looked
    at yet.

    * tstuu.c (main, uchoose, fwriteable): Roberto Biancardi: use poll
    if we haven't got select.

    * uucico.c (zget_uucp_cmd): Michael Haberler: some systems send \n
    after Shere, rather than a null byte.

Tue Mar  3 01:03:22 1992  Ian Lance Taylor  ([e-mail])

    * uuxqt.c (main, uqdo_xqt_file): permit local executions, don't
    get grade out of system dependent file name.

    * sys4.unx (fsysdep_get_work): Bob Denny: warn if we can't open a
    command file.

    * v2.c (uv2_read_systems): Jeff Putsch: infinite loop when reading
    time string.

    * uucp.h, sys1.unx, sys2.unx, sys3.unx, tstuu.c, configure.in:
    Thomas Fischer: some NeXT compatibility stuff: removed externs of
    sleep and alarm, included <libc.h> in uucp.h.

    * uucp.h, port.h, uucico.c (zget_uucp_cmd, zget_typed_line),
    port.c (cdebug_char, udebug_buffer), chat.c (icexpect, fcsend,
    fcphone), log.c (ulog): Michael Richardson: added LOG_DEBUG_START,
    LOG_DEBUG_CONTINUE and LOG_DEBUG_END to allow a debugging line in
    the log file to be built character by character.  Used this new
    feature in chat script debugging, rather than having each
    character appear on a separate line.  Added fPort_debug variable
    to control port debugging.

    * uustat.c (fsquery, fsquery_system, fsquery_show): handle
    execution files queued up for the local system correctly when
    using -q option (they still don't show up on any other option).

    * uucp.texi, protg.c (fgstart, fgshutdown): Aleksey P. Rudnev:
    added remote-window and remote-packet-size 'g' protocol
    parameters.  Reset the parameters to their default values in
    fgshutdown.

    * sysh.unx, sys2.unx (fsserial_read, usalarm), sys1.unx
    (usset_signal, usysdep_detach), uucico.c (main): overhauled
    fsserial_read yet again.  The timeout passed in is now an absolute
    bound.  A special SIGALRM handler does some wierd stuff to avoid
    any possible race.

    * config.c (uread_config), sysinf.c (uiread_systems,
    fcallout_login, fcheck_login), prtinf.c (ffind_port,
    fread_dialer_info), chat.c (fctranslate), uucico.c (faccept_call):
    T. William Wells: when using HAVE_TAYLOR_CONFIG in combination
    with V2 or BNU configuration files, don't complain if the
    HAVE_TAYLOR_CONFIG files are missing.

Mon Mar  2 10:21:36 1992  Ian Lance Taylor  ([e-mail])

    * sys2.unx (fsserial_read): T. William Wells: don't arbitrarily
    extend read timeout.

    * uux.c (main): check iSignal before entering fread, since the
    user may have hit ^C earlier in the program.

Sun Mar  1 23:39:33 1992  Ian Lance Taylor  ([e-mail])

    * policy.h, uucp.h, sysh.unx, sys2.unx (fsserial_lock,
    fsysdep_modem_close, fsysdep_direct_close), util.c (strlwr),
    configure.in: Marc Unangst: added HAVE_SCO_LOCKFILES configuration
    parameter to force lock file names to lower case.

Fri Feb 28 00:07:12 1992  Ian Lance Taylor  ([e-mail])

    * system.h, uucico.c (faccept_call, fdo_xcmd), uuxqt.c
    (uqdo_xqt_file), uux.c (main), uucp.c (main, ucspool_cmds),
    sys3.unx (zsysdep_spool_cmds), uux.1, uucp.1: added -j switch to
    uucp and uux to display the jobid of the spooled job.

    * uucp.h, system.h, sysh.unx, uucico.c (fuucp, fdo_xcmd,
    fok_to_send, fok_to_receive), uuxqt.c (uqdo_xqt_files), uux.c
    (main, uxcopy_stdin), uucp.c (main), file.c (freceived_file),
    config.c (fin_directory_list), sys1.unx (fsysdep_file_exists,
    fsuser_access, fsysdep_in_directory), sys3.unx (esysdep_open_send,
    fsysdep_move_file), sys5.unx (fsysdep_xqt_check_file): Chip
    Salzenberg: recheck file access permissions before sending, to try
    to avoid symbolic link games.  Check that the user has search
    access on all directories down to the file, and read or write
    access to the file or directory itself.  Check in uucp and uux as
    well as uucico, to provide early messages.  Check the standard
    input file in uuxqt.  Be more careful about creating files in the
    spool directory.  This eliminates all security problems I know of,
    except for a very short race in fsysdep_move_file.

    * sys3.unx (esysdep_open_send): give an error message if we try to
    send a directory (used to just fail silently).

    * system.h, sysh.unx, sys1.unx (usysdep_detach, ussignal,
    fsysdep_catch, usysdep_start_catch), sys2.unx
    (fsysdep_modem_end_dial, fsserial_read), uux.c (main): T. William
    Wells: fsysdep_catch obviously must be a macro, since it calls
    setjmp.  Also TIOCNOTTY sets the process group to 0, so we don't
    have to fork before calling it.

Thu Feb 27 00:08:09 1992  Ian Lance Taylor  ([e-mail])

    * sys1.unx, sys6.unx, sys7.unx: added some extern definitions.

    * configure.in, uucp.h, system.h, sysh.unx, uucico.c (main,
    ucatch, uabort, zget_typed_line, zget_uucp_cmd), uuxqt.c (main,
    uqcatch, uqabort), uux.c (main, uxcatch, uxrecord_file, uxabort),
    uucp.c (main, uccatch, ucrecord_file, ucabort), uustat.c (main,
    uscatch), uulog.c (main, ulcatch), uuname.c (main, uncatch),
    uucheck.c (main, ukcatch), log.c (ulog_fatal_fn, ulog,
    ulog_close), tstuu.c (main, uchild, uprepare_test), sys1.unx
    (usysdep_initialize, usysdep_detach, usysdep_signal,
    fsysdep_catch, usysdep_end_catch, ussignal, fsset_signal,
    fsysdep_run, raise), sys2.unx (usalarm, usysdep_pause,
    fsserial_lock, fsserial_open, fsysdep_stdin_close,
    fsysdep_modem_close, fsysdep_modem_end_dial, fsserial_read,
    fsserial_write, fsserial_io), sys5.unx (fsysdep_execute): T.
    William Wells: overhaul to support detaching from the terminal and
    completely reliable signals.  uucico now calls usysdep_detach at
    various points; new option -D prevents detaching.  The signal
    handling code all goes through usysdep_signal, fsysdep_catch and
    usysdep_end_catch.  A signal now just sets iSignal, which is
    checked at various points, notably in the port routines and in the
    main loops in uucico and uuxqt.

Tue Feb 25 10:59:23 1992  Ian Lance Taylor  ([e-mail])

    * protg.c (fgwait_for_packet): Bob Denny: reset the count of
    timeouts only when data is recognized, so that we aren't fooled by
    a sequence of imperfect echoes.

    * sys5.unx (zsysdep_get_xqt): Bob Denny: don't warn if opendir
    gets ENOENT.  I think POSIX requires ENOTDIR, but what can you do?

Mon Feb 24 14:37:10 1992  Ian Lance Taylor  ([e-mail])

    * uucico.c (main, uusage): don't treat an extra argument as a port
    name.

    * sys3.unx (esysdep_truncate): Roberto Biancardi: support F_CHSIZE
    and F_FREESP in esysdep_truncate.

    * configure.in, sys2.unx (fsserial_read, usysdep_pause): Roberto
    Biancardi: use poll to sleep less than a second if we haven't got
    anything else.

    * v2.c (uv2_read_systems, fv2_find_port), bnu.c
    (ubnu_read_systems, fbnu_find_port, fbnu_read_dialer_info),
    uustat.c (fsworkfile_show): Roberto Biancardi: skip spaces and
    tabs after doing a strtok ((char *) NULL, "").

    * copy.c (fcopy_file), sys1.unx (esysdep_fopen), sys2.unx,
    sys3.unx (esysdep_open_receive, esysdep_truncate, fsdo_lock,
    fscmd_seq), sys5.unx (fsysdep_execute), sys7.unx, tstuu.c: John
    Theus: some systems use <sys/file.h> instead of <fcntl.h>.  Also
    changed the code to call creat instead of open when appropriate.
    Should now work on V7, with the exception of O_NONBLOCK and
    O_NDELAY in sys2.unx and tstuu.c.

    * uucp.h: John Theus: if we don't have vprintf, ulog is defined
    without an ellipsis, so don't declare it with one.

Sun Feb 23 14:45:53 1992  Ian Lance Taylor  ([e-mail])

    * uucp.h, system.h, bnu.c (ubnu_read_systems), config.c
    (fin_directory_list), sys1.unx (fsysdep_in_directory), sys5.unx
    (fsysdep_xqt_check_file), uucp.c (main), uuxqt.c (uqdo_xqt_file),
    uucico.c (fdo_xcmd, fok_to_send, fok_to_receive), tstuu.c
    (uprepare_test): only permit files to be received into directories
    that are world writeable.  Check for this in fsysdep_in_directory,
    with a new argument.  Changed calls appropriately.  In tstuu
    create /usr/tmp/tstuu as world writeable.

    * bnu.c (ubadd_perm_alternate): Doug Evans: after all that, I got
    it wrong: WRITE only applies to remote requests.

    * uucp.h, uucico.c (fuucp, fdo_xcmd, fok_to_send, fok_to_receive),
    uuxqt.c (uqdo_xqt_file), uuchk.c (ukshow), sysinf.c
    (uset_system_defaults, tialternate), sys5.unx
    (fsysdep_xqt_check_file), bnu.c (ubadd_perm_alternate): fixed READ
    and WRITE handling to match BNU semantics.  Added
    zcalled_local_send, zcalled_local_receive, zcalled_remote_send and
    zcalled_remote_receive fields to ssysteminfo structure for this,
    and handled them in all the appropriate places.

Sat Feb 22 22:30:59 1992  Ian Lance Taylor  ([e-mail])

    * Complete overhaul of configuration to use automatic shell
    script.  Eliminated conf.h, now generated by configure.  Renamed
    Makefile to Makefile.in.  Added policy.h for administrative
    decisions and other choices which can not be made automatically.
    Many changes to many source files, none having to do with code.

Thu Feb 20 17:57:55 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (fdo_call): Chip Salzenberg: some systems truncate the
    Shere= machine name to 7 characters.

Wed Feb 19 14:36:31 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * sys7.unx (fskill_or_rejuv): make sure that only the submitter or
    the superuser is permitted to cancel (or rejuvenate) a request.

    * system.h, sysh.unx, sys3.unx (zsfile_to_jobid, zsjobid_to_file),
    sys4.unx (zsysdep_jobid), sys7.unx, uustat.c, Makefile, MANIFEST:
    wrote uustat.  Changed CSEQLEN in sys3.unx from 5 to 4.  Added
    several new system dependent functions, mostly in sys7.unx.

    * system.h, sys1.unx, log.c, file.c, chat.c, protg.c, uucico.c:
    rearranged the time functions for the convenience of uustat.  Made
    isysdep_time take an optional pimicros arguments.  Renamed
    usysdep_full_time to isysdep_process_time, and made clear that it
    need only work within a single process.  Changed usysdep_localtime
    to take a time returned by isysdep_time rather than always use the
    current time.  Changed the calls as appropriate.

Tue Feb 18 14:03:19 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uuxqt.c (main): pass fdaemon argument correctly to
    usysdep_initialize.

Mon Feb 17 17:09:16 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uuxqt.c (uqdo_xqt_file): T. William Wells: make sure sh uses
    absolute path of command, rather than relying on PATH.

    * sys5.unx (zsysdep_find_command): Michael Nolan: allow full
    command name to be specified by remote system, not just basename,
    if command is not in path.

    * log.c (ulog): don't use headers when outputting to terminal.

    * sys2.unx (fsrun_chat): Bob Denny: log chat program messages as
    LOG_NORMAL, not LOG_ERROR.

Fri Feb 14 00:17:57 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (ucatch), uuxqt.c (uqcatch): Neils Baggesen: under
    HAVE_BNU_LOGGING, don't lose the system name when dieing.

    * uulog.c, Makefile, MANIFEST: wrote uulog.

    * uuname.c, Makefile, MANIFEST: wrote uuname.

    * bnu.c (ubadd_perm_alternate): T. William Wells: must xstrdup the
    system name before calling uadd_validate.

    * log.c (ulog_close): Micheal Nolan: don't refer to eLdebug if the
    DEBUG configuration parameter is 0.

    * uucp.c (main): Niels Baggesen: abtname must be copied into
    memory, or it will be overwritten by the next file to be copied.

Sun Feb  9 00:12:58 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (fuucp), prot.c (fsend_file, freceive_file): Bob Denny:
    call fmail_transfer before calling fsysdep_did_work, because the
    latter frees up strings used by the former.

    * sysh.unx, sys1.unx (mkdir), uudir.c (new file), Makefile: added
    HAVE_MKDIR configuration parameter for systems without the mkdir
    system call.  The emulation function in sys1.unx invokes the new
    suid program uudir which sets its uid to uucp and invokes
    /bin/mkdir.  Added rules to create uudir to Makefile.

Sat Feb  8 14:25:50 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * sysh.unx, sys1.unx (opendir, readdir, closedir), sys4.unx,
    sys5.unx: added HAVE_OLD_DIRECTORIES configuration parameter to
    support systems without opendir/readdir/closedir which use
    original Unix directory format.

    * sysh.unx, sys1.unx (dup2): added HAVE_DUP2 configuration
    parameter and dup2 emulation function.

    * sys1.unx (zsysdep_local_name): put utsname structure on stack
    rather than making it static.

    * sysh.unx, sys1.unx (usysdep_initialize, getcwd): if we have
    neither getcwd nor getwd, fork /bin/pwd to get the current working
    directory.

    * system.h, uucico.c (main), uuxqt.c (main), uux.c (main), uucp.c
    (main), uuchk.c (main), sys1.unx (usysdep_initialize), sys6.unx
    (fsysdep_needs_cwd, zsysdep_add_cwd): because getting the current
    working directory can be expensive on Unix, since some
    implementation of getcwd fork a shell to execute pwd, only try to
    get the cwd if it is going to be needed by uux or uucp.

    * uucico.c (main), uuxqt.c (main), uux.c (main), uucp.c (main),
    uuchk.c (main), log.c (ulog): handle all possible signals raised
    by abort, namely SIGABRT, SIGILL and SIGIOT.  In ulog always call
    abort rather than raise (SIGABRT).

    * sys4.unx (usysdep_get_work_free): the qSwork_file information
    was freed up incorrectly if a file transfer failed.

    * sysh.unx, sys2.unx: Archaic Zilog System III computers use
    setret and longret rather than setjmp and longjmp, so I added a
    HAVE_SETRET configuration option.

    * prott.c (ftstart, ftsenddata): shifts of integers by more than
    15 are not portable.

    * prot.c (fsend_file, freceive_file, fploop, fgot_data): I ran
    into an old compiler which couldn't handle the calls to pffile, so
    I simplified them to use a variable.

    * port.c (fmodem_dial): cast result of alloca.

    * getopt.h, getopt.c: Jay Vassos-Libove: renamed getopt and
    related variables by macro defining them to gnu_*.  This avoids
    conflicts with system header files and system libraries.

Fri Feb  7 12:08:42 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * everything: added HAVE_STRING_H and HAVE_STRINGS_H.  Removed
    include of <string.h> in every source file and put it in uucp.h.
    Since I had to change everything anyhow, added 1992 to the
    copyright date.

    * uucico.c (fcall): Bob Denny: retry time not reached is not
    really an error, so just make a normal log entry for it.

Sun Feb  2 01:38:47 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uucp.c (main): Get the file name for the destination of a local
    copy using zsysdep_real_file_name rather than zsysdep_in_dir,
    since the latter doesn't get the basename of the argument.

    * sys3.unx (fsysdep_get_status): Niels Baggesen: cast enum to int
    before comparison.

    * system.h, uucp.c (main), uux.c (main), sys6.unx (fsysdep_access,
    fsysdep_daemon_access): Niels Baggesen: check user access to file
    since programs are running setuid.  Previously uucp and uux
    permitted a file readable only by uucp to be transferred to
    another system by user request!

    * chat.c (fchat): Michael Nolan: portions of a chat string might
    be separated by more than just a single space if they are read
    from a V2 or BNU configuration file.

Fri Jan 31 19:51:57 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * protg.c: Chip Salzenberg: change default window size to 7.

    * sys3.unx (fsdo_unlock): Michael Nolan: cast result of alloca to
    (char *), not that it really matters.

    * log.c (ulog): Michael Nolan: if SIGABRT is not defined, just
    call abort.

Thu Jan 30 18:19:33 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * bnu.c (ubadd_perm): Michael Nolan: debugging check was done
    wrong for entry with LOGNAME but no MACHINE.

Wed Jan 29 13:28:59 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (zget_uucp_cmd): Patrick Smith: only wait a short time
    for the hangup string.

    * sys4.unx (iswork_cmp): Patrick Smith: fixed casts to not cast
    away const.

Tue Jan 28 11:06:34 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * sys1.unx, sys3.unx, tstuu.c: Jay Vassos-Libove: removed some
    declarations of system functions that conflict with system header
    files on BSD/386 alpha.

    * Makefile: Jeff Ross: make sure the uninstall target restores the
    original file owner and mode.

    * protg.c (fgsendcmd): the previous patch wasn't really correct.

Mon Jan 27 22:30:47 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * log.c (ustats): Marty Shannon: don't report a failed transfer
    under USE_BNU_LOGGING.

    * sys3.unx (zsysdep_real_file_name): Marty Shannon: a trailing '/'
    on the name means that it is a directory, even if the directory
    does not already exist.

    * uucico.c (fuucp): Marty Shannon: the -f flag indicating that
    directories should not be created was not being handled correctly.

    * uucico.c (fcall): Chip Salzenberg: set .Status correctly if
    wrong time to call.

    * protg.c (fgsendcmd): John Antypas: didn't handle null byte at
    end of command which was exactly a power of two in length
    correctly.

Tue Jan 21 14:37:10 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * Released version 1.02.

    * system.h, uucico.c (main), uux.c (main), uucp.c (main,
    zcone_system), sys1.unx (fsysdep_run): Chip Salzenberg: have uucp
    and uux start up uucico -s system rather than uucico -r1.

Mon Jan 20 11:45:38 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * sys1.unx (fsysdep_make_dirs): don't try to create a directory
    with no name.

    * version.c: change version number to 1.02.

    * uucico.8, uuxqt.8, uucp.1, uux.1: change version number to 1.02.

    * MANIFEST: removed texinfo.tex; it's twice the size of any other
    file, so I think it's just to large to distribute.

    * uucico.c (fcall, fdo_call): Marty Shannon: update the time in
    the .Status file if it's the wrong time to call, and upon
    receiving a call.

Sun Jan 19 13:29:23 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * protg.c (fgsendcmd, fgsenddata): Dave Platt: if the remote UUCP
    accepts packets larger than 64 bytes, assume it can handle
    differing packet sizes, so if we have a small amount of data to
    send, use a small packet.  Besides the two routines mentioned,
    also made minor changes to other routines to get the packet length
    out of the packet data rather than always assuming the same packet
    size.

    * conf.h, uucp.h: Matthew Lyle: some systems don't declare errno
    in <errno.h>, so I added HAVE_ERRNO_DECLARATION.

    * conf.h, uucp.h, util.c (bsearch): added HAVE_BSEARCH
    configuration parameter.

Sat Jan 18 17:45:28 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * tstuu.c (utransfer): Mike Park: don't sleep when the input
    buffer is full; it's too slow.

    * Makefile: when making a distribution,change the mode of separate
    copies of the configuration files Makefile, conf.h and sysh.unx.

    * uucico.c (faccept_call): Marty Shannon: update .Status file on
    incoming calls.

    * uucp.h, prot.h, uucico.c (fuucp), prot.c (fsend_file,
    fpsendfile_confirm, freceive_file, fprecfile_confirm, fxcmd,
    ustats_failed), file.c (fsent_file, usendfile_error,
    freceived_file, urecfile_error, frecfile_rewind, fmail_transfer):
    reworked calls to fsydep_did_work and sending of mail messages to
    be more sensible.  Now sends mail to requestor if request fails
    permanently and does not remove file if request fails only
    temporarily.

Thu Jan 16 11:33:08 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * protg.c (fgsendcmd, fgsenddata): zero out unused bytes in short
    packets.

    * prot.c (zgetcmd), protf.c (ffsendcmd), prott.c (ftsendcmd),
    prote.c (fesendcmd): Niels Baggesen: added some debugging
    messages.

    * protg.c (fgsendcmd): corrected misspelling in debugging message.

    * log.c (ustats): Niels Baggesen: add FAILED to end of xferstats
    line if appropriate.

    * uuxqt.c (uqdo_xqt_file): Niels Baggesen: was checking strcmp
    return value incorrectly, so messages to other systems were not
    being sent.

    * sys2.unx, tstuu.c: Mike Park: ioctl is sometimes declared
    varadic, so we can't declare it.

Wed Jan 15 02:03:43 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * sys1.unx: put \n at end of fsysdep_run error message.

    * sysh.unx, sys1.unx, sys2.unx, tstuu.c: Mike Park: on some
    systems <sys/time.h> includes <time.h> but <time.h> can only be
    included once; added HAVE_SYS_TIME_AND_TIME_H to sysh.unx.

    * tstuu.c: Mike Park: removed prototype for times since some
    systems don't have clock_t.

    * conf.h, sys2.unx, util.c: Mike Park: some systems don't have
    <limits.h>.  Every macro used from it already had a check to make
    sure it was defined anyhow.

    * tstuu.c (uprepare_test): Mike Park: sh on NeXT interprets a
    leading ~, so we have to quote the argument to system(3).
    Incredible.

    * conf.h, uucp.h: Mike Park: if HAVE_ALLOCA is 0 when compiling
    with gcc, don't define alloca as a macro.  This will let the NeXT
    define it in some header file.

    * sysh.unx, sys2.unx, sys5.unx, tstuu.c: Mike Park: handle
    HAVE_UNION_WAIT completely.  Assume that system(3) returns an int
    which should be put into the w_status field.  Define macros for
    union wait if they are not already defined.  Move all this stuff
    into sysh.unx rather than duplicating it in three different files.

    * conf.h, uucp.h, sysh.unx, config.c, bnu.c, v2.c, uucico.c,
    uuxqt.c, uux.c, uucp.c, uuchk.c, Makefile: set directory to look
    for configuration files in in Makefile rather than in sysh.unx.
    This forced a number of changes, as now all new style
    configuration files are looked up using NEWCONFIGLIB.  Old style
    configuration files are looked up using OLDCONFIGLIB.

Mon Jan 13 00:35:43 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * sys3.unx: David Nugent: don't declare chmod, since it may be
    prototyped to take an argument that is smaller than an int.

    * uucico.c (faccept_call): Chip Salzenberg: only declare sportinfo
    if it will be used (if HAVE_TAYLOR_CONFIG is true).

    * sys3.unx (isysdep_get_sequence): Chip Salzenberg: avoid use
    before set warning from gcc.

    * protf.c (ffprocess_data): Chip Salzenberg: avoid use before set
    warning from gcc.

    * sysh.unx, sys2.unx (fsserial_read, usysdep_pause): Chip
    Salzenberg: added HAVE_USLEEP configuration parameter for the AIX
    usleep routine.

    * uuchk.c, prtinf.c, config.c: Chip Salzenberg: strcmp is a macro
    on AIX, so avoid declaring it and undef it in config.c where we
    want to declare it because we want to take its address.

    * uucp.h, sys3.unx (fsysdep_get_status, fsysdep_set_status): Chip
    Salzenberg: handle out of range status codes in status files.

    * Makefile, sysh.unx: defined LIBDIR in the Makefile, rather than
    forcing the user to define it in two different places.

    * sys.unx, tstuu.c: Chip Salzenberg: can't declare execl, since it
    is varadic.

    * sys1.unx, sys2.unx, sys3.unx, sys5.unx, tstuu.c: David Nugent:
    can't declare open or fcntl, since they may use ... in header file
    prototype; added declaration for popen; added casts of first mkdir
    argument to char *.

    * sysh.unx, tstuu.c (uchild): Mike Park: added HAVE_WAITPID and
    HAVE_WAIT4 configuration parameters to allow the use of wait4 as
    found on the NeXT.

    * tstuu.c (uprepare_test): Mike Park: use IPUBLIC_DIRECTORY_MODE
    rather than S_IRWXU | S_IRWXG | S_IRWXO.

    * sysinf.c (tisystem): Mike Park: ulog was being passed the wrong
    number of arguments.

Sun Jan 12 14:32:47 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * Eliminated CONFIG, INSTALL and THANKS.  They are now included in
    uucp.texi.  Changed README and MANIFEST accordingly.  Added
    uucp.info* and texinfo.tex to MANIFEST.

    * Makefile, uucp.texi: renamed taylor.texi to uucp.texi.

    * uucico.c (fcall, fdo_call): John Antypas: pass in sportinfo
    structure for fdo_call to use for an unknown port.

    * log.c (ulog): allocate enough bytes to name file if
    HAVE_BNU_LOGGING is in use but zLogfile has no %s.

Sat Jan 11 12:11:56 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * Makefile: changed to correspond to GNU standards, according to
    standards.text of 24 Nov 91.

    * Makefile: Franc,ois Pinard: use $(INSTALL_PROGRAM) and
    $(INSTALL) rather than cp to install the programs.

    * time.c (ftime_now), sys1.unx (usysdep_localtime): John Antypas:
    use memcpy to get the result of localtime rather than relying on
    structure assignment.

    * sysh.unx, prtinf.c: Hannu Strang: changed definition of
    SYSDEP_STDIN_CMDS to pass structure instead of address of
    structure to avoid bug in AIX compiler which causes it to fail to
    recognize an address constant containing the -> operator.

Tue Jan  7 10:22:43 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * Released beta 1.02.

    * protg.c (fgcheck_errors): discount out of order packets in the
    total error count, and allow a negative error count to mean that
    any number of errors are accepted.

    * sysinf.c (tadd_proto_param): Niels Baggesen: allocate number of
    protocol parameters based on *pc, not sIhold.cproto_params.

Sat Jan  4 16:42:21 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * log.c (ulog): tweaked HAVE_V2_LOGGING slightly.

    * v2.c (uv2_read_systems): set chat script correctly.

    * uucp.h, sys3.unx: avoid redefining SEEK_SET if it appears in
    <unistd.h> but not <stdio.h>.

    * chat.c (fcsend): made fcsend into a static function.

    * uucp.h, uucico.c, uuxqt.c, uux.c, uucp.c, uuchk.c, version.c:
    changed abProgram and abVersion from const char [] to char []
    because the Microsoft compiler on SCO can't handle const char []
    arrays correctly.

    * uux.c (main): allocate enough space for log message.

    * sys1.unx (usysdep_localtime): to get the current time, we can't
    call usysdep_full_time if the latter uses times.

    * sys1.unx, sys3.unx: added a couple more extern definitions for
    SCO 3.2.2.

    * uucico.c (main): start uuxqt even if a call fails.

    * sysh.unx, system.h, uuxqt.c (uqdo_xqt_file), sys5.unx
    (fsysdep_xqt_check_file): Chip Salzenberg: added configuration
    option ALLOW_FILENAME_ARGUMENTS to permit arguments that look like
    filenames, to allow undoing the patch I just made.

Fri Jan  3 00:44:59 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * system.h, uuxqt.c (uqdo_xqt_file), sys5.unx
    (fsysdep_xqt_check_file): David J. Fiander: make sure that if an
    argument looks like a filename we are permitted to access it.

    * sys3.unx (fsdo_lock): remove temporary file if link fails in
    fsdo_lock.

Thu Jan  2 00:01:53 1992  Ian Lance Taylor  (ian at comton.airs.com)

    * protg.c (fgstart, fgshutdown, fgprocess_data): count remote
    rejections separately from resent packets when counting errors.

Tue Dec 31 14:31:38 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * protg.c (fgstart): Franc,ois Pinard: forgot to initialize
    cGdelayed_packets.

    * prot.h, uucico.c, prote.c: added the 'e' protocol, creating the
    new file prote.c

    * prot.c (freceive_data), protf.c (fffile), prott.c (ftfile):
    changed pffile protocol entry point to pass number of bytes being
    sent; fixed bug in freceive_data which caused to ask for the wrong
    number of bytes when the buffer was empty.

Mon Dec 30 23:16:48 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * sys2.unx (fsserial_open): Chip Salzenberg: don't turn on IXON
    and IXOFF initially; after all, the initialization packets might
    contain an XOFF character.

Sun Dec 29 00:00:42 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucp.h, prot.c (fploop): John Theus: check for EOF before
    reading from file to work around bug in Tektronix library.

    * protg.c (fprocess_data): don't send RR packets when an error
    occurs; the other side will probably ignore them, and it may
    confuse some Telebit modems.

    * sys1.unx (usysdep_localtime): don't take the address of a cast
    value.

    * log.c (zldate_and_time): wasn't allocating enough buffer space.

Sat Dec 28 01:09:58 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uuxqt.c (uqdo_xqt_file): forgot to initialize zmail.

    * uucp.h, time.c, copy.c, sys1.unx, sys2.unx, sys3.unx, sys4.unx,
    sys5.unx, config.c, log.c, uuxqt.c, uux.c, tstuu.c: added a bunch
    of externs to decrease the number of implicit function
    definitions.

    * system.h, sys1.unx (usysdep_localtime), log.c (zldate_and_time):
    Lele Gaifax: put the full year in the log file, using the format
    YYYY-MM-DD HH:MM:SS.HH (ending in hundredths of seconds).

    * config.c (uprocesscmds): Terry Gardner: allow a # to be quoted
    in a configuration file.  Also made uprocesscmds reentrant.

    * sysh.unx, sys2.unx (fsrun_chat), sys5.unx (fsysdep_execute),
    tstuu.c (uchild): Monty Solomon: added HAVE_UNION_WAIT
    configuration option to pass a variable of type union wait to the
    wait and waitpid system calls.

    * sysh.unx, sys1.unx (usysdep_initialize): John Theus: added
    HAVE_GETWD to use getwd instead of getcwd.

    * sysh.unx, sys1.unx (usysdep_full_time): added HAVE_FTIME
    configuration option.

    * tstuu.c (uchild): use TIMES_TICK from sysh.unx rather than
    CLK_TCK.

    * conf.h, uucp.h, util.c, getopt.c, tstuu.c: added HAVE_STRCHR and
    HAVE_INDEX to conf.h.

Fri Dec 27 01:00:41 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (fuucp): set fmasterdone correctly when running as a
    slave.

    * port.c (cpshow, upshow, fport_read, fport_write, fport_io):
    cleaned up debugging code by isolating out upshow and by making
    cpshow handle backslash.

    * tstuu.c (uprepare_test): create spool directories by hand, to
    make sure test 6 can be done and to test creating needed
    directories.

    * conf.h, uucp.h, bnu.c, v2.c, chat.c, protg.c, prott.c, sysinf.c,
    tcp.c, getopt.c, tstuu.c, util.c: added HAVE_MEMFNS and HAVE_BFNS
    to conf.h.  Changed memset calls to use bzero.

    * protg.c (fgcheck_errors, fgprocess_data): added protocol
    parameter ``errors'' to set maximum number of errors permitted.
    Also made fgprocess_data only reply once per batch of data.

Thu Dec 26 17:54:54 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * tcp.c (ftcp_dial, itcp_port_number): Monty Solomon: cast
    arguments to avoid prototype errors on NeXT.

Mon Dec 23 00:16:19 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucp.h, sysinf.c, uucico.c (main, flogin_prompt, faccept_call),
    uuchk.c (main): David Nugent: allow debugging level to be set for
    a specific system.

Sun Dec 22 15:51:10 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * conf.h, uucp.c, sysh.unx, tcp.c, sys1.unx, sys2.unx, sys3.unx,
    sys5.unx, sys6.unx, tstuu.c: Monty Solomon: added HAVE_UNISTD_H to
    conf.h for systems which don't have <unistd.h>.  Also added
    externs for all functions from <unistd.h>, which required adding
    definitions for pid_t, uid_t and off_t to sysh.unx.

    * config.c, prtinf.c, time.c, uuchk.c: added externs for
    strcasecmp or strncasecmp, to avoid implicit function definitions
    now that I took the prototypes out of uucp.h.

    * sys3.unx (fsysdep_get_status): Franc,ois Pinard: the code added
    to avoid scanf had a stupid bug.

    * uucp.h: Monty Solomon: removed prototypes for strcasecmp and
    strncasecmp from uucp.h, since they may be in string.h.

Sat Dec 21 16:04:58 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucp.h, uucico.c (ucatch), prot.c (fpsendfile_confirm,
    fprecfile_confirm, ustats_failed), file.c (fsent_file,
    freceived_file), log.c (ustats): Terry Gardner: record failed file
    transfers in the statistics file.

    * uucico.c: change protocol ordering to 't', 'g', 'f'.

    * uucico.c (faccept_call), tstuu.c (uprepare_test): John Theus:
    don't warn if the port file doesn't exist when the slave mode
    uucico looks up the port.

    * sys1.unx, sys5.unx: moved fsysdep_file_exists from sys5.unx to
    sys1.unx so that uucico can call it.

    * uux.c: Fran,cois Pinard: remove parentheses from ZSHELLSEPS so
    that they may be used to quote arguments as documented.  This
    means that may not be used to start subshell, but that is no great
    loss.

    * uux.c (main): use ulog to report illegal grade error message.

    * sys1.unx (fsysdep_run): use the real program name from abProgram
    in the error messages in fsysdep_run.

Thu Dec 19 19:02:28 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (fdo_call, faccept_call): Terry Gardner: put the length
    of the conversation in the ``Call complete'' log file message.

    * uux.c: added space and tab to ZSHELLSEPS, because otherwise the
    command was parsed to include whitespace.

    * protg.c, protf.c: Oleg Tabarovsky: added statistical logging
    messages to the 'g' and 'f' protocols.  These go to the main log
    file right now, but I'm not sure if that's appropriate.

    * sys2.unx (fsserial_set): don't change terminal settings if we
    don't have to.

    * port.c (fport_io): add complete diagnostics for fport_io so we
    can see every byte that goes in or out.

    * uucico.c (fuucp): don't give user name in errors produced by
    getting the next command.

    * uuxqt.c (main): don't process execute files for unknown systems.
    This is not unreasonable, I hope, and it avoids errors caused by
    an uninitialized sUnknown structure.

    * sys4.unx (fsysdep_get_work_init): sort the previously found
    files all together so we can correctly check new files using
    bsearch.

    * protf.c (pfprocess, pfprocess_data, pfwait): Franc,ois Pinard:
    don't kill 'f' protocol because of an illegal byte.  Also slightly
    optimized the protocol to wait for up to seven characters at a
    time rather than just one.

Wed Dec 18 00:12:42 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * sysh.unx, sys2.unx, tstuu.c: Terry Gardner: added
    USE_FOR_UNBLOCKED configuration parameter to support systems that
    don't permit O_NONBLOCK and O_NDELAY to both be set.

    * tstuu.c (uchild): give the uucico processes a chance to die on
    their own rather than killing them immediately.

    * uuxqt.c (main, uqdo_xqt_file): David Nugent: keep rescanning the
    list of execute files until nothing can be done.  Also, don't
    remove the execute file if we get some sort of internal error.

    * sys4.unx (fsysdep_get_work, usysdep_get_work_free): David
    Nugent: after we've processed all the work files we found
    initially, rescan the work directory to pick up any that may have
    come in in the meantime.  Also, reset iSwork_file to 0 in
    usysdep_get_work_free so that we can handle more than one system.

    * tstuu.c, uucico.c (main, fwait_for_calls, flogin_prompt): added
    -l option to uucico to prompt for the login name and password once
    and then exit.

Tue Dec 17 00:24:41 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucp.h, uucico.c, uuxqt.c, uux.c, uucp.c, config.c
    (uread_config), log.c (ulog): eliminated ulog_program and added
    abProgram and ulog_to_file.  Made log messages output to stderr
    more Unix like.

    * log.c (ulog): use a fixed number of fields in a log file message
    by replacing a missing system or user with '-'.

    * port.h, chat.c (renamed fchat_send to fcsend), bnu.c
    (fbnu_read_dialer_info), prtinf.c (tpcomplete), sys2.unx
    (fsysdep_modem_close), uuchk.c (ukshow_dialer): T. William Wells:
    change the modem complete and abort strings into chat scripts.

    * sys2.unx (fsserial_open): on BSD start in RAW mode to avoid
    dropping characters when we switch over.  I originally thought
    being able to use XON/XOFF was worth the risk; I no longer think
    so.

    * tstuu.c (uprepare_test): have shell script sleep before printing
    the login name to make sure the second system has finished
    flushing its input buffer.

    * protg.c (fginit_sendbuffers), prott.c (ftsendcmd): David Nugent:
    avoid sending confidential information by zeroing out memory
    buffers before using them.

    * sysinf.c (tirequest, titransfer), prtinf.c (tpseven_bit,
    tpreliable, tpdtr_toggle): Marc Unangst: several functions did not
    accept true and false as boolean strings, contradicting the
    documentation.

    * uucp.h, system.h, sysh.unx, sys1.unx (usysdep_full_time), file.c
    (fstore_sendfile, fsent_file, fstore_recfile, freceived_file),
    log.c (ustats): generate statistics in microseconds instead of
    seconds for more accurate time keeping.

    * sys2.unx (fsserial_open): David Nugent: flush pending input
    when a serial port is opened.  This will clear out a
    NO\sCARRIER string left by a previous dropped connection.

Mon Dec 16 11:26:17 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * uucico.c (main), uuxqt.c (main), tstuu.c (main, uchild): David
    Nugent: ignore SIGHUP in uucico and uuxqt, so that they are
    unaffected by the parent shell closing down and by the remote
    terminal dropping the connection.

    * bnu.c (ubnu_read_sysfiles, ubnu_read_systems, fbnu_find_port,
    fbnu_read_dialer_info): Mike Bernson: ignore lines that begin with
    whitespace, fix compilation error.

Sat Dec 14 20:59:10 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * sys2.unx (fsserial_open): don't turn on ISTRIP initially.

    * uucp.h, sysinf.c, chat.c (icexpect), uuchk.c (ukshow_chat):
    added chat-seven-bit command to allow control over whether
    parity bits are stripped out of chat scripts.

    * uucp.h, port.h, chat.c (fchat, fcprogram),
    config.c (tprocess_one_cmd), prtinf.c,
    sysinf.c (tichat, tprocess_chat_cmd),
    bnu.c (fbnu_read_dialer_info), port.c (fpdo_dial),
    uucico.c (fdo_call, faccept_call) uuchk.c (ukshow_chat):
    changed processing of chat commands to go through
    tprocess_chat_cmd, avoiding repetition.  All chat script
    information is now held in an schat_info structure.
    Eliminated the fchat_program function, renaming it fcprogram
    and making it static to chat.c (it is now called via fchat).
    Added CMDTABTYPE_PREFIX.  Added INIT_CHAT macro to initialize
    chat script information.  Added TTYPE_CMDTABTYPE and
    CARGS_CMDTABTYPE to eliminate hex constants in
    tprocess_one_cmd.

    * sys5.unx (zsysdep_get_xqt): Oleg Tabarovsky: don't stop
    processing files just because opendir failed on one; it could just
    be because we don't have read permission.

Fri Dec 13 17:43:52 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * config.c (uprocesscmds): don't continually allocate and free the
    array of arguments.

Thu Dec 12 12:46:01 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * prot.c (fgetcmd): Franc,ois Pinard: don't bother to give an
    error if the final HY doesn't come in; apparently the MtXinu UUCP
    doesn't send it.

    * chat.c (icexpect, fchat_send): Franc,ois Pinard: add some chat
    script debugging messages.

    * log.c (ulog): David Nugent: move ERROR: from the start of the
    line to after the date and time; this makes it easier to use awk
    on log files.

    * sys3.unx (fsdo_lock), sys1.unx (usysdep_initialize): do locking
    using link rather than O_CREAT | O_EXCL to avoid race conditions
    and to safely run as the superuser.

    * sys3.unx (fsysdep_move_file): fcopyfile now creates the
    destination file with IPRIVATE_MODE, so we don't need to chmod to
    it.

    * sys1.unx (usysdep_initialize, fsysdep_other_config): set the
    GID as well as the UID, in case anybody wants to run this as a
    setgid package.

Wed Dec 11 10:03:22 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * conf.h, uucp.h, util.c (strtol): Mark Powell: added my own
    version of strtol to util.c, for systems which lack it.

    * protg.c (fgstart, fgexchange_init): if we start resending
    packets during initialization, don't forget which packets we have
    already seen; otherwise the other side may assume we've already
    seen them while we're looking for them.

Tue Dec 10 15:42:41 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * conf.h, sysh.unx, log.c (ulog, ustats), tstuu.c (uprepare_test):
    Arne Ludwig: merged in Arne Ludwig's patches to support V2 and BNU
    style logging, with some minor additions and changes.

    * sys1.unx, sys3.unx, sys5.unx, uux.c, uucp.c, uucico.c, copy.c,
    uucp.h, system.h: create directories when necessary rather than
    assuming that they exist.  Added fmkdirs argument to esysdep_fopen
    and fcopy_file, changing all calls.  Added fpublic argument to
    fsysdep_make_dirs, changing all calls.  Moved fsysdep_make_dirs
    and fsdirectory_exists from sys3.unx to sys1.unx.  Added checks
    for ENOENT in several places in sys3.unx and sys5.unx.

    * log.c, port.c (fport_open), sys2.unx (fsserial_open): added
    ulog_device routine to record device name.  This is currently only
    used for the BNU statistics file, but more uses might arise later.

    * file.c, log.c, uucp.h: moved statistics file routines from
    file.c to log.c in preparation for supporting BNU log file
    routines.

Mon Dec  9 12:00:52 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * bnu.c (ubnu_read_systems): Arne Ludwig: the device entry for a
    system can be followed by a comma and a list of protocols.

    * sysh.unx, sys3.unx (fsdo_lock): Richard Todd: add
    HAVE_V2_LOCKFILES, in which the process ID is written out in
    binary.

    * uuxqt.c (uqdo_xqt_file): Richard Todd: the requestor address is
    relative to the requesting system.

    * config.c (uprocesscmds, umulti_pushback): Richard Todd: each
    line pushed back because of "#" is local to a particular
    smulti_file structure.

    * prtinf.c (asPdialer_cmds): Richard Todd: exit the current dialer
    if the special command "#" is seen.  A similar thing should be put
    in for ports, but it's marginally more complex.

    * config.c (uprocesscmds): Richard Todd: don't warn if the special
    "#" command is unrecognized.

Sat Dec  7 13:05:40 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * config.c (uprocesscmds): Franc,ois Pinard: don't limit the
    number of arguments to a command!

    * chat.c (fchat): handle a chat script which consists only of a
    single string.

Fri Dec  6 16:11:29 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * sys5.unx (fsysdep_execute): David J. Fiander: if execve fails
    with ENOEXEC, try using /bin/sh with a quoted argument.

    * uux.c (main): split arguments the way /bin/sh does.  If any
    shell metacharacters appears, request uuxqt to execute the command
    using /bin/sh.

    * tstuu.c (uprepare_test): allow the uux to test to send a failure
    message.

    * uuxqt.c (uqdo_xqt_file): don't send mail on successful execution
    unless specifically requested; pay attention to the 'n' line
    which requests mail on success; ignore the 'Z' line because it
    now specifies the default action.

    * sys1.unx (usysdep_initialize), sys6.unx (zsysdep_add_cwd):
    Franc,ois Pinard: getcwd may legitimately fail, so only give an
    error if we really need the result.

    * chat.c (ccescape): Franc,ois Pinard: ccescape should never
    return a negative number, since the callers don't know how to deal
    with that.

Mon Dec  2 16:26:16 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * bnu.c (ubnu_read_systems): Dave Buck: time strings with grades
    were parsed in an endless loop!

    * sys3.unx (fsdo_lock, fsdo_unlock): the alloca when using LOCKDIR
    was one byte too small.

    * config.c (tprocess_one_cmd): pass 10 to strtol rather than 0 to
    avoid surprises if a leading zero is used.

    * prtinf.c (tpproto_param, tpdialer_proto_param): Niels Baggesen:
    the ``protocol-parameter'' command didn't work for ports or
    dialers.

Sun Dec  1 09:46:12 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * tstuu.c: don't use the fd_set typedef at all.

    * tstuu.c (uprepare_test): don't read V2 or BNU configuration
    files while testing.

    * bnu.c, v2.c, config.c (uread_config): David Nugent: even if the
    code was compiled with HAVE_TAYLOR_CONFIG, read the V2 and BNU
    configuration files if the code was compiled to support them.

    * uuchk.c (fkshow_port): Bob Izenberg: report dialer/token pairs
    correctly.

Sat Nov 30 17:40:00 1991  Ian Lance Taylor  (ian at comton.airs.com)

    * tstuu.c: Bob Izenberg: copied over conditional definitions of
    EAGAIN and EWOULDBLOCK from sys2.unx.

    * bnu.c (fbnu_read_dialer_info): Niels Baggesen: accept dialers
    with no substitutions.

    * bnu.c (ubnu_read_systems, ubadd_perm): Niels Baggesen: don't
    free up zline in ubadd_perm; in fact, changed the calling sequence
    to not even pass zline in at all.

    * bnu.c (ubadd_perm): Niels Baggesen: didn't handle multiple
    MACHINE= and multiple LOGNAME= values in a single Permissions
    line, because it was clobbering the machine name while processing
    the first logname.

    * bnu.c: Made zread and zwrite elements of sperm structure const
    char * to avoid warning.

    * copy.c, sys1.unx, sys2.unx, sys3.unx, sys5.unx, tstuu.c: Niels
    Baggesen: don't multiply include <unistd.h>.  Eventually there
    should be a macro controlling whether it gets included at all, for
    non-POSIX systems.

    * sys3.unx (fsysdep_get_status, isysdep_get_sequence): Marty
    Shannon: accept a truncated status file.  I also eliminated scanf
    calls in sys3.unx, since that was the only place it was called;
    this was to make the executables smaller for systems which cared.

    * bnu.c (ubnu_read_sysfiles): Marty Shannon: accept comment
    characters in Sysfiles.

    * sysh.unx, sys3.unx: Marty Shannon: added HAVE_RENAME, put a fake
    rename system call in sys3.unx.

    * prtinf.c (ffind_port): Marty Shannon: failed to handle multiple
    ports in the port file since I forgot to reset my pointer
    variable.

    * bnu.c (ubnu_read_systems): Marty Shannon: don't initialize the
    auto array abpubdir, since old cc didn't permit initialization of
