1986-05-18  Richard M. Stallman  (rms@prep)

        * alloc.c (malloc_warning_1): Add some advice on
        the significance of the warning.

1986-05-09  Richard M. Stallman  (rms@prep)

        * sysdep.c (get_screen_size):
        Reject values of TIOCGSIZE if they are ridiculous.

1986-05-05  Richard M. Stallman  (rms@prep)

        * process.c (send_process_1):
        If pipe buffer is full, wait a second and try again.

1986-05-02  Richard M. Stallman  (rms@prep)

        * termcap.c (tputs): Round rather than truncating
        when dividing padcount.

1986-04-24  Richard M. Stallman  (rms@prep)

        * insdel.c (del_range): Args passed to adjust_markers
        are now properly adjusted for the gap.

1986-04-20  Richard M. Stallman  (rms@prep)

        * alloca.c: Declare xmalloc.

1986-04-17  Richard M. Stallman  (rms@prep)

        * filelock.c (unlock_buffer): New function to unlock
        a specified buffer.  Use in Fdelete_buffer_internal
        to avoid lossage if buffer being killed is not current.

1986-04-14  Richard M. Stallman  (rms@prep)

        * alloc.c (malloc_warning, Fgarbage_collect):
        If malloc_warning is called during GC, just save warning
        in malloc_warn_string.  Try again to warn when GC ends.

1986-04-08  Richard M. Stallman  (rms@prep)

        * indent.c (compute_motion):
        Change unsigned short back to short.  unsigned short is plain
        wrong and causes infinite loops when horizontal scrolling is used.
        Introduced macros HPOS and VPOS for extracting components of cpos.
        Alternate HPOS definition for Celerity since casting to (short)
        loses there.

1986-04-07  Richard M. Stallman  (rms@prep)

        * dispnew.c (update_screen):
        Don't zero OPhysScreen and DesiredScreen until after
        final error check.  Omit the error check unless debug_end_pos.

1986-04-06  Richard M. Stallman  (rms@prep)

        * cm.c (calccost):
        Was returning garbage if arrived at fail: by goto fail;.

        Appending the arg to the file name must be done
        whether or not CANNOT_DUMP.

1986-03-25  Richard M. Stallman  (rms@prep)

        * fileio.c (Fsubstitute_in_file_name):
        // at beginning of filename is meaningful on Apollo.

        * crt0.c: If NEED_ERRNO defined, declare errno.
        * m-7300.h: New file.

1986-03-25  Richard Mlynarik  (mly@prep)

        * alloc.c (Fmake_symbol):
        CHECK_STRING the argument.

1986-03-24  Richard M. Stallman  (rms@prep)

        * xfns.c (Fx_proc_mouse_event):
        Use shifts rather than byte addressing to extract from .detail.

1986-03-24  Richard Mlynarik  (mly@prep)

        * minibuf.c (do_completion):
        Only funcall predicate if it is non-nil
        Make completion of "nil" in obarrays work.

1986-03-21  Richard M. Stallman  (rms@prep)

        * fileio.c (Fsubstitute_in_file_name):
        #if 0 last change (LOGNAME); it makes vax running 5.0 crash.

1986-03-20  Richard M. Stallman  (rms@prep)

        * unexec.c (make_hdr): Avoid comparing a_bss field with 0.
        It is unsigned on some machines.  Save sbrk (0) in tem.

1986-03-19  Richard M. Stallman  (rms@prep)

        * minibuf.c (do_completion):
        Don't say string is exact match if it fails the predicate.

        * process.c (create_process):
        For STRIDE: use FIONBIO to make pipe/pty non-blocking.
        The fcntl alone failed to do it.

        * fileio.c (Ffile_directory_p, Ffile_modes):
        Don't remove trailing slash for stat if path is "/".

        * process.c (kill_buffer_processes):
        Pass nil, not 0, to sig_process for current_group arg.

1986-03-18  Richard M. Stallman  (rms@prep)

        * s-usg*.h, s-unipl*.h:
        Replace default ADDR_CORRECT with a no-op.
        Default triggers compiler bug on some systems.
        Remove same thing from m-stride.h since now redundant there.

        * keyboard.c (init_keyboard, interrupt_signal):
        For USG, handle SIGQUIT just like SIGINT.

        * sysdep.c (init_sys_modes):
        For HPUX, use C-g for the SIGQUIT char as well as the SIGINT char
        as using CDEL causes Meta-DEL to send a SIGQUIT!

        * process.c: On Uniplus, time.h is under sys/, as in bsd.

        * sysdep.c (reset_sys_modes):
        Don't use FASYNC if it is not defined.

        * cm.c (calccost): Refuse to use incremental cursor motion
        after wrapping on terminals with MagicWrap (xn flag).

1986-03-13  Richard M. Stallman  (rms@prep)

        * emacs.c (main): For APOLLO: reserve 4meg with set_sbrk_size.

        * alloc.c (Fpurecopy): Fix typo unsignedint.

1986-03-12  Richard M. Stallman  (rms@prep)

        * dired.c (file_name_completion):
        Allow exact match against an ignored extension.
        Can thus delete foo.o even if foo.out exists.

        * s-hpux.h: Turn off HAVE_PTYS since their csh has "sanity
        checking" and other programs seem to lose with ptys.

1986-03-11  Richard M. Stallman  (rms@prep)

        * sysdep.c ({un,}request_sigio and callers):
        Make alternate names init_sigio and reset_sigio;
        callers in sysdep.c use those names.
        In 4.1, change {un,}request_sigio to do sighold/sigrelse;
        don't change init_sigio and reset_sigio.

        * m-vax.h: If USG5_2, use -lPW and HAVE_ALLOCA.

        * alloc.c (Fpurecopy, mark_object): In tests for pureness,
        always use XUINT and unsigned comparison.
        * lisp.h (CHECK_IMPURE): Likewise.

        * doc.c (FSnarf_documentation):
        If CANNOT_DUMP, find DOC in directory PATH_EXEC.

        * ymakefile (APOLLO only): Set LTERMCAP.
        * m-apollo.h: Alter VALBITS and GCTYPEBITS.

        * term.c (delete_chars): Pass num chars to the hook.
        * term.c (raw_topos), termhooks.h: Add raw_topos_hook.

        * unexec.c (make_hdr):
        New compiler switch NO_REMAP means don't change text/data boundary.

1986-03-10  Richard M. Stallman  (rms@prep)

        * indent.c, window.c, xdisp.c:
        Make compute_motion, vmotion and display_text_line
        all return a pointer to a global structure, not a struct itself.
        Add * to all calls.

        * syntax.c (scan_sexps_forward):
        Make it return a pointer to a global structure,
        not a struct itself.  Change caller (Fparse_partial_sexp).

        * m-hp200.h: No longer needs to #define static.

        * unexec.c (adjust_lnnoptrs):
        Replace dummy defn with one that does the job.  Also
        involves including syms.h and making global vars
        bias and lnnoptr that are set in make_hdr.

1986-03-08  Richard M. Stallman  (rms@prep)

        * editfns.c (init_editfns):
        Make AMPERSAND_FULL_NAME case start with USER_FULL_NAME.

        * crt0.c (BOGUS case):
        Move "start:" from non-tower32 case to unconditional.

        * unexec.c [COFF]:
        Put the rounding-to-page-boundaries of section positions
        within the file into a UMAX conditional.  (See Feb 19).

1986-03-06  Richard M. Stallman  (rms@prep)

        * ymakefile: Add -k100000 switch to ld, for celerity.

        * eval.c (funcall_lambda):

        New subroutine that does the reading and handling of process output.
        Do so until none is left.
        (wait_reading_process_input): Call new subroutine.
        (sig_process): If we get a pgrp number, make it negative.
        Always send signal to pggrp; use killpg if BSD, kill otherwise.
        (child_signal): Don't deactivate dead processes here.
        (change_msgs): Deactivate them here, when notification is done.
        But first, call read_process_output to get any output that's left.

        * keyboard.c (read_avail_input):
        (for sysV) Use fcntl, not ioctl, to make read not wait.

        * alloca.s: Put entire file inside #ifndef HAVE_ALLOCA.

        * sysdep.c (child_setup_tty, init_sys_modes):
        (for sysV) Set VTIME to zero; with VMIN=1 this means
        no time limit.

1986-03-02  Richard M. Stallman  (rms@prep)

        * keyboard.c (quit_throw_to_get_char):
        Before really throwing, clear waiting_for_input
        so another interrupt won't also try to throw.
        (get_char): Add error check for getcjmp being zero
        where it should not be.  Put this under DEBUG switch.

1986-03-01  Richard M. Stallman  (rms@prep)

        * crt0.c: Defining BOGUS forces use of the vax-tahoe-sequent case.
        Add a small conditional within it for tower32.
        Don't allow use of the m68000/m68k code if BOGUS is defined.

        * sysdep.c (init_sys_modes):
        For sysV: If want flow control, actively set IXON,
        and also clear IXANY if that is defined.

        * sysdep.c (rename):
        It was doing completely wrong things to various files.

        * tparam.c (tgoto): Move buf outside the function
        and rename as tgoto_buf.  In case #define static as nothing.

        * unexec.c (make_hdr):
        If macro EXEC_MAGIC is defined, let it specify the magic
        number for the output file.

        * xdisp.c (message): Change name `buf' to `message_buf'
        to avoid name clash when #define static as nothing.

        * lread.c (Fload):
        Detect when fdopen returns 0 given a valid descriptor.

        * sysdep.c (stuff_char):
        Declare arg as char, so TIOCSTI does not give wrong address.

1986-02-25  Richard M. Stallman  (rms@prep)

        * dispnew.c (update_screen):
        * xdisp.c (DoDsp, Fredraw_display):
        Insert checks to abort if screen_height is zero,
        to detect the memory clobbering bug.

        * process.c:

        Don't HAVE_TIMEVAL.  Define open as sys_open and lstat as stat.
        Define the O_ symbols for open args.
        Turn off CLASH_DETECTION, for now.  Turn off HAVE_TIMEVAL.

        * sysdep.c (bcopy, bzero, bcmp):
        Make them really do the work, not try to use memset, memcopy, etc.

        * sysdep.c (get_system_name):
        4.1 needs its own definition of this.

        * sysdep.c (for BSD 4.1):
        Define sys_open, since 4.1 open takes only two args.
        Redefine LLITOUT as 0; it loses in 4.1.

1986-02-22  Richard M. Stallman  (rms@prep)

        * alloca.s (hack_sky):

        * dispnew.c (update_screen):
        Don't free a line twice if it is in both DesiredScreen
        and OPhysScreen.  Can happen if line is copied into
        DesiredScreen by `scrolling', then lost from PhysScreen
        by the scrolling that is done.
        Also remove a debugging check that did not go off
        when this bug hit.

        * ymakefile:
        Don't use -X for BSD systems that use COFF.
        On UMAX, give ld the file align.umax (a new file)
        via the make-macro ALIGNMENT.

        * align.umax, s-umax.h:
        Two new files for Encore computers.

        same code and control how many args to ignore.

        * unexec.c: For sequent machine, handle its incompatible

1986-02-06  Richard M. Stallman  (rms@prep)

        * indent.c (compute_motion):
        For tabs, make sure to take remainder of positive #

        (init_sys_modes, child_setup_tty): Init VTIME to a large #, not 0.
        Use TCSETA, not TCSETAW (why wait?).

        * process.c:
        (wait_reading_process_output): If don't HAVE_TIMEVAL
        and no timeout desired, use 100000 seconds, which
        the select emulator recognizes.
        When reading data, if a char is buffered in proc_buffered_char,
        put it at the front of the data read.
        (kill_buffer_process): Ignore processes really already dead.
        (init_process): Initialize proc_buffered_char to -1 (empty).

        * keyboard.c (fake_suspend):
        Don't mess with the SIGCLD handler.
        Use wait_for_termination to detect subshell termination.
        (read_avail_input, for USG):
        Use TCSETA, not TCSETAW; no waiting.

1986-01-26  Richard M. Stallman  (rms@prep)

        * fns.c (Frandom):
        Removed case for number as arg, since it has problems
        in union-type case and it is not documented or used.

        * lisp.h (XSET):
        Fix bugs in the union-type definition.

1986-01-24  Richard M. Stallman  (rms@prep)

        SKTPAIR-or-not now controls only what to do if cannot use a pty.
        For USG other than UNIPLUS, instead of sigsetmask (nonexistent),
        save away and temporarily turn off the SIGCHLD handler.
        (child_sig): Various USG changes.

        * sysdep.c (wait_for_termination):
        Provide case for sysV not UNIPLUS (right for STRIDE at least).
        * sysdep.c (child_setup_tty):
        Set the VMIN and VTIME fields.

        * callint.c (Fcall_interactively):
        Globalize the variable argfuns, for HPUX's sake.

        No need to conditionalize recipes for xfns.o and xterm.o.
        No longer need to duplicate the xemacs: line.
        For HPUX, define LIBBSD.  Use that in LIBES.

        * editfns.c (init_editfns):
        Handle case of pw == 0 (USER is not a known user).

        * cm.c:

        If HPUX, insert time.h instead of sys/time.h.

        * sysdep.c:
        If HPUX, insert time.h instead of sys/time.h.
        In get_system_name, globalize a static variable `name'.

        Make some system-call imitations "not HPUX".

        * process.c:
        If HPUX, insert time.h instead of sys/time.h.
        Do them only if HAVE_TIMEVAL.
        If HAVE_PTYS and HPUX, insert sys/ptyio.h.

        * term.c:
        (term_init): If TERMINFO, where tbuf is not used,
        allocate combuf with size 2044.
        (evalcost): Flush it.  Make it extern and use the one in cm.c.

        * dired.c:
        Include stat.h before config.h so config can override S_IFLNK on
        HPUX (where that symbol exists but there are no symbolic links).
        Do not include time.h; not needed.

        * xdisp.c (fmodetrunc, decode_mode_spec):
        Rename local static buffers buf, tbuf and make them global.
        Static variables go into initialized data space in HPUX.
        * fns.c (Fload_average):
        Similar hack for internal static vars initialized, channel, nl.

        * lread.c:

        * alloc.c (init_alloc_once):
        Fix erroneous names data_bytes_{un,}used
        inside the VIRT_ADDR_VARIES conditions.

        * emacs.c:
        Don't include time.h or resource.h; just #define PRIO_PROCESS.

        * xdisp.c (redisplay_window):
        Don't shift window-start to avoid end of buffer
        unless window contents have changed too.

        * xdisp.c (DoDsp):
        If nothing has changed except minibuffer message,
        no need to call redisplay_window.

        Problem: standard sysV has no file ioctl.h.

        * process.c, keyboard.c, dispnew.c, sysdep.c:
        Include ioctl.h in BSD, termio.h and/or fcntl.h in sysV.

        * callproc.c: No longer needs ioctl.h; don't include.
        * xdisp.c: No longer needs ioctl.h or signal.h; don't include.

        * emacs.c:
        Include sys/ioctl.h only for BSD.  ioctl used only in BSD.

1986-01-21  Richard Mlynarik  (mly@prep)

        * keyboard.c (EchoThem):
        Always display an explicit prompt, even if echo_keystrokes == 0.

1986-01-21  Richard M. Stallman  (rms@prep)

        * keyboard.c (kbd_buffer_store_char, fake_suspend):
        Take the STRIDE code for subshell out of kbd_buffer_store_char
        and call it fake_suspend.  Call it from previous place and
        also from Fsuspend_buffer, on all systems that lack SIGTSTP.
        Clean the code up a little bit.

        * process.c:
        Don't include sgtty.h; no longer needed.
        Make use of wait3 depend on existence of WNOHANG.

        * unexec.c:
        Allow the m- file to override defn of ADDR_CORRECT (m-stride.h does).
        Have and use pagemask to round data_start in COFF case too.
        Always define getpagesize as macro, for 4.1 and USG where
        it is not provided as a system call.
        This takes care of the STRIDE changes for unexec.

        * ymakefile:
        Give ld the arg $(STARTFLAGS), and define that based on cpp macro
        TEXT_START_ADDR when that is defined.  This is for systems where
        the -T switch is necessary.

        * unexec.c (make_hdr):
        Make one sun3 fix machine-independent.
        (Prevent a_bss from being negative).

        * casefiddle.c (casify_region):
        New flag value CAPITALIZE_UP which is like CAPITALIZE
        but changes only the initials.  Function upcase_initials_region
        is an interface to this mode.

        * abbrev.c (Fexpand_abbrev): Use upcase_initials_region.

        * process.c (create_process):
        Install Fish's other new UNIPLUS conditionalization
        on the hackery for xforkin, etc.

1986-01-20  Richard M. Stallman  (rms@prep)

        * fns.c (Frandom):
        Optional arg of t means randomize the seed.
        This change was really made at some previously time;
        just changed the doc string now.

        * eval.c (do_autoload):
        Bind autoload-queue to avoid loss on recursive autoloads.

        * xdisp.c (try_window_id):
        If everything on screen below change is whitespace,
        don't scroll, and return -2.

        * dispnew.c (update_screen):
        Rewrite to avoid dependence on distance between
        the two arrays PhysScreen and DesiredScreen.

1986-01-19  Richard M. Stallman  (rms@prep)

        * fns.c (mapcar1):
        Preinitialize contents of vals, so it won't contain junk
        to be seen by a GC inside this function.

        * eval.c (various):
        Use error, not Fsignal, to report eval-depth-overflow.
        Previous calls to Fsignal were buggy.

1986-01-17  Richard Mlynarik  (mly@prep)

        * lread.c (init_obarray):
        Kludge around losing pyramid compiler.

        through some bug I don't understand, killed.

        * keymap.c (get_keyelt), keyboard.c (Fcommand_execute):
        Allow (lambda ...) to appear as a key's definition.

        * m-sun3.h, unexec.c:
        Sun3 changes from Barry Shein.

1986-01-10  Richard Mlynarik  (mly@prep)

        * m-stride.h, s-stride.h, crt0.c, fns.c, keyboard.c, process.c,
          sysdep.c.
        Changes for STRIDE micro
        Changes still pending for etc/loadst.c.

        Fsuspend_emacs in keyboard.c is defined to run a subshell under
        emacs -- perhaps this is a reasonable thing in all wimpy unix
        versions.

1986-01-10  Richard M. Stallman  (rms@prep)

        * dispnew.c (update_line):
        Don't consider spaces at beginning as special if line is
        highlighted.
        Avoids losing the inverse-video on leading spaces in mode lines
        on terminals where erasing does not turn on highlightig (vt100?).

        * process.c (pty):
        On UNIPLUS, don't try opening other side.

        * filelock.c (lock_file_1):
        If lock file is invalid, delete it and continue.
        If delete fails, ignore the lock.

1986-01-09  Richard Mlynarik  (mly@prep)

        * syntax.c:
        New function check_syntax_table.

        Make Fmodify_syntax_entry take third arg SYNTAX-TABLE,
        which defaults to current buffer's syntax table.
        -- doc change in auxdoc.c.

        Rename Fmake_syntax_table FCopy_syntax_table
        after making it take an arg (default Vstandard_syntax_table)
        -- retain alias in subr.el.

1986-01-08  Richard M. Stallman  (rms@prep)

        * sysdep.c, term.c (get_screen_size):
        New function to get screen size from kernel when possible.
        In sysdep; called from term_init in term.c.
        Must test this on Sun and on 4.3.

        * dispnew.c (Fding):
        Make doc say it terminates kbd macros.

        Fix typo in name synch_process_pid.

1985-12-27  Richard M. Stallman  (rms@prep)

        * s-unipl5.2.h:
        Define HAVE_SELECT.

        * ymakefile (xemacs):
        If the commands are conditional, the target/dependencies line must
        be conditional also.

1985-12-20  Richard M. Stallman  (rms@prep)

        * print.c (printchar, strout):
        If output stream is Qt and noninteractive,
        don't do the usual interactive output stuff.
        In strout, avoid changing i so do not truncate the output.

1985-12-19  Richard M. Stallman  (rms@prep)

        * fns.c (merge):
        Don't assume args are consecutive; GCPRO each one separately.

        * insdel.c (make_gap):
        Was adding k bytes of gap; k is supposed to be
        new desired amount of gap.  Wasted a lot of memory!

        * alloc.c (malloc_warning):
        Passing Fprinc to internal_with_output_to_temp_buffer
        loses since Fprinc needs 2 args.  Use intermediate
        function malloc_warning_1.

1985-12-18  Richard M. Stallman  (rms@prep)

        * filelock.c (lock_if_free):
        Kill failing means lock is free only if errno is ESRCH.

        * fns.c (Fy_or_n_p, Fyes_or_no_p):
        Call Fdiscard_input if user gives invalid answer.

1985-12-17  Richard M. Stallman  (rms@prep)

        * eval.c (apply_lambda):
        Do debug-on-exit here, because if we return to Feval
        the stack vector of evaluated args will be deallocated by then.

        * sysdep.c (wait_for_termination):
        Add new variable wait_debugging.  Set it nonzero to make
        this function work in a way that works under dbx.

        * process.c (send_process_1):
        If not all the data is written, try again to write the rest.
        Eliminate the alarm stuff, including send_process_alarm.
        Call report_file_error if write returns negative.

1985-12-15  Richard M. Stallman  (rms@prep)

        * alloc.c (init_alloc_once):

        New Lisp primitives, needed for the things that
        are put on the command history for "r" arguments.

        * callint.c (Fcall_interactively):
        If an argument was point or mark, represent it with
        a suitable expression (point) or (mark) in the
        command history element.  Also adjust for changed
        calling conventions of quotify_args.

        * callint.c (quotify_arg):
        Take one arg; return it if constant, else return
        a quote-expression for it.

        * callint.c (quotify_args):
        Don't exempt the first arg.  Use quotify_arg to do the work.

1985-12-13  Richard M. Stallman  (rms@prep)

        * fileio.c (Fdo_auto_save):
        Use message1 to output "Auto-saving..."
        so do not clobber the old message to be restored at end.

1985-12-12  Richard M. Stallman  (rms@prep)

        * syntax.c:
        After turning on immediate_quit, must do QUIT.

        * callproc.c (Fcall_process):
        Quitting out of running subproc did not happen immediately.
        Added QUIT;s after setting immediate_quit on,
        removed those after turning it off (not needed there).

        * lread.c (init_read):
        Don't put ../lisp on Vload_path if CANNOT_DUMP.

        * emacs.c (main):
        If CANNOT_DUMP, load "loadup.el" as soon as enter editor loop
        unless -nl switch is given.

        * lread.c (read_list):
        Don't use Fsetcdr, since might be changing a cell
        in pure space during initial loadup.
        Do explicit assign instead.

        * lisp.h:
        Define CHECK_IMPURE, to get error if object is pure.

        * data.c (Fsetcar, Fsetcdr, Faset):
        Use CHECK_IMPURE instead of old error checking code.

        * data.c (pure_write_error):
        New subroutine, called by CHECK_IMPURE.

        * m-apollo.h:
        Define VIRT_ADDR_VARIES.

        * alloc.c:
        We now load things into pure space even if cannot dump,
        to speed garbage collection.
        Turn on Vpurify_flag unconditionally.
        Give pure its full size unconditionally.
        Change remaining CANNOT_DUMP and APOLLO conditionals
        into VIRT_ADDR_VARIES conditionals.

1985-12-10  Richard M. Stallman  (rms@prep)

        * fns.c:
        Don't include files for load-average if load-average not supported.

        * alloc.c:
        If CANNOT_DUMP, allocate `pure' very small.
        [This has been undone.]

        * buffer.c (list_buffers_1):
        Use 2 spaces minimum only after buffer name;
        go back to 1 space minimum after size and major mode.

        * termcap.c:
        Avoid use of O_RDONLY and index, so no need for explicit
        dependence on system type.

        * sysdep.c:
        Delete definition of `index'.  Now it's a macro when nec.

        * s-usg5.2.h, s-unipl5.2.h:
        Define index and rindex as macros.

        * dispnew.c (Fsit_for):

        Dump core if bf_p1, bf_p2 don't differ by gap size.

        * keyboard.c (Fsuspend_emacs):
        * emacs.c (Fkill_emacs):
        Both call new subroutine stuff_buffered_input (in keyboard.c)
        which stuffs a string's contents plus any unused input Emacs has
        already read.

1985-12-09  Richard M. Stallman  (rms@prep)

        * fileio.c (Fdo_auto_save):
        Don't auto save a buffer that is not modified
        since last real save.

        * minibuf.c (minibuffer_completion_help_1):
        Use make_number for args to Findent_to.
        Omitting make_number always loses on Pyramid, it seems.

1985-12-08  Richard M. Stallman  (rms@prep)

        * minibuf.c (Fminibuffer_complete_word):
        If next char not unique, try adding an actual space.
        If do achieve some completion, replace old buffer text
        with the completion (in case of different case).
        Also a little cleanup.

        * minibuf.c (Ftry_completion):
        Fix lossage when second completion found is an initial segment of
        the first one.

        * xdisp.c (redisplay_window):
        Don't use the clause for only-point-has-changed
        for the minibuffer; loses when redisplaying to bring
        back minibuffer after an echo area message.

        * crt0.c:
        Vax code is now used for tahoe machine also.

        * alloc.c (init_alloc_once):
        For APOLLO, set data_bytes_{free,used} to plausible constant
        values.

        * eval.c (unautoload):
        Declare return type Lisp_Object.

        * filelock.c (lock_file):
        Check attack with !NULL, not ==.

        * keymap.c (describe_command):
        Don't apply NULL directly to result of Fkeymapp.

        * lisp.h (XSET):
        Fix type field assignment in union-type case.

        * process.c (Faccept_process_output):
        Use XFASTINT around infd field of process.

        * search.c (signal_failure):
        Returns type Lisp_Object.

        * dired.c (Ffile_name_completion):
        If arg is null string, return null string immediately.
        Idea is don't want to complete "/foo/" into "/foo/bar"
        if "bar" is the only file in "/foo/".

        * minibuf.c (Ftry_completion):
        Handle correctly scmp returning -1.

        * alloc.c:
        Make malloc_sbrk_used and malloc_sbrk_unused
        not be external if APOLLO.

1985-12-06  Richard M. Stallman  (rms@prep)

        * emacs.c, keyboard.c, sysdep.c:
        Rename InitDsp -> init_sys_modes and RstDsp -> reset_sys_modes.

        * emacs.c (main):
        Call init_keyboard before init_sys_modes
