        (Vxrdb_name): New variable.
        (Fx_get_resource): Use it instead of Vinvocation_name.

        * s/aix3-2.h (C_SWITCH_SYSTEM): Don't define this to be "-ma" if

        * systty.h (HAVE_LTCHARS, HAVE_TCHARS): New macros; define them if
        we have those structures, but *don't* define them if we have
        TERMIOS, whose functions take care of those parameters; that
        screws up AIX.
        (struct emacs_tty): Test those symbols, instead of the ioctl
        commands.
        * sysdep.c (emacs_get_tty, emacs_set_tty, new_ltchars, new_tchars,
        init_sys_modes): Same.

        * config.h.in (HAVE_RENAME): Include an #undef for this, so

        LD_SWITCH_SYSTEM, OLDXMENU_OPTIONS): Add X11R5 directories to the
        search paths in these lists; they shouldn't do any harm if they

        GCC.

        * keyboard.c (read_char): If kbd_buffer_get_event returns nil,
        redisplay and retry.
        (kbd_buffer_get_event): If event is handled here, return nil.
        (swallow_events): New function.

        * m/symmetry.h (PTY_TTY_NAME_SPRINTF, PTY_NAME_SPRINTF):
        Use pty_name, not ptyname.

1993-05-25  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * Version 19.8 released.

1993-05-25  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xfns.c: Clear out the old face stuff.
        (x_face_table, n_faces, x_set_face, x_set_glyph, Fx_set_face_font,
        Fx_set_face, Fx_get_face): Removed.
        (syms_of_xfns): Remove defsubr for Fx_set_face.

        Arrange for font names to get fully resolved - no wildcards.
        * xfns.c (x_set_frame_parameters): Store the value in the frame
        parameter alist before we call the setter function, so the setter
        function can touch up the value if it chooses.
        (x_set_foreground_color, x_set_background_color): Call
        recompute_basic_faces, so their GC's will reflect the changes.
        (x_new_font): Add extern declaration - this returns a Lisp_Object
        now, the fully resolved font name.
        (x_set_font): Accept the fully resolved name from x_new_font, and
        put it in the frame's parameter alist.  Call recompute_basic_faces.
        * xterm.c (x_new_font): Return the fully resolved font name, Qnil
        (if no match), or Qt (match, but unacceptable metrics).
        * xterm.c (x_new_font): Don't call init_frame_faces.

        * xterm.h: New section for declarations for xfaces.c.
        (init_frame_faces, free_frame_faces, intern_face,
        face_name_id_number, same_size_fonts, recompute_basic_faces,
        compute_char_face, compute_glyph_face): Declare these here.
        * xfaces.c (same_size_fonts): We can now remove this extern
        declaration.
        * xfns.c (face_name_id_number): Likewise.
        * xterm.c (intern_face): Likewise.

        * xterm.c (dumpglyphs): Remember that the default faces can have
        null fonts, too.

        * xfns.c (Fx_list_fonts): Remember that FACE may not have a font
        specified.  Don't specify 30000 as the maximum limit on the number
        of fontns returned  - 2000 is more reasonable. 

        * xfaces.c (build_face, unload_font, free_frame_faces): Don't
        forget to block input while making X calls.

        Treat faces as structures specifying modifications to the frame's
        parameters, rather than things which need to specify a complete
        set of parameters by themselves.
        * xfaces.c (init_frame_faces): Don't set up the two frame display
        faces by querying the GC - just leave all their fields blank, and
        call recompute_basic_faces, letting build_face do the work of
        consulting the frame when necessary.
        (recompute_basic_faces): New function.
        (compute_base_faces): New function for obtaining the "identity"
        for compute_char_face and compute_glyph_face.
        (compute_char_face, compute_glyph_face): Call it, instead of copying
        FRAME_DEFAULT_FACE.
        * xfns.c (x_make_gc): No need to call init_frame_faces here.

        * xfaces.c (intern_frame_face): This can be static.

        * dispextern.h (struct face): New field - `copy', to help us with
        resource allocation.
        * xfaces.c (free_frame_faces): Do free the first two faces; don't
        free anything from a face that's a copy.
        (intern_frame_face): Mark every face we intern as a copy; its
        resources are actually a combination of the real faces.
        (Fset_face_attribute_internal): No need to check if we're trying
        to free one of the frame's GC's; they never enter into the
        picture.

        * casetab.c: Fix formatting, so as not to confuse etags.

        * xfns.c (Fx_list_fonts): New function.
        (face_name_id_number): Add extern declaration for this.
        * xfaces.c (face_name_id_number): Make this externally visible,
        and make the FRAME argument a FRAME_PTR, not a Lisp_Object.
        (compute_char_face): Call face_name_id_number properly.

        * xfaces.c (unload_color): Don't free the pixel for now.

        * xfaces.c (merge_faces): You can't tell if a font is a
        character-cell font or not by testing whether or not it has a
        per_char table.  They all do.
        * xterm.c (x_new_font): Same deal.
        * xfns.c (Fx_list_fonts): Same deal.

        * m/iris4d.h: Dyke out the section which specifies how to get the
        load average.

        * paths.h (PATH_INFO): New path, to edited by the configuration
        process.
        * callproc.c (Vconfigure_info_directory): New variable, used
        internally by build process.
        (syms_of_callproc): DEFVAR it and initialize it.

        * keyboard.c (Fcurrent_input_mode): Use XFASTINT to build the last
        element of the return value, not XSETINT.

1993-05-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        Changes for OSF/1:
        * mem-limits.h [__osf__ && (__mips || mips)]: #include
        <sys/time.h> and <sys/resource.h>.
        (get_lim_data): OSF wants a definition like BSD4_2's.
        * s/osf1.h: #include "bsd4-3.h", not "s-bsd4-3.h".

        * ymakefile (LIBX): Put LD_SWITCH_X_SITE before the libraries, so
        it actually has an effect.

        Some makes can't handle form feed characters in their makefiles.
        * s/usg5-3.h: Remove form feed.
        * s/template.h, m/template.h: Remove form feeds.

        * xfns.c (select_visual): Include the screen number in the
        template of things XGetVisualInfo must match.

        the right buffer.

1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (modify_event_symbol): If a name_table elt is null,
        generate a name to use.  Don't crash.

        * fileio.c (Fread_file_name): If input is empty, do return the default
        even if !insert_default_directory.

        * xterm.c (XTread_socket): For ConfigureNotify event,
        translate coordinates if send_event field is false
        provided the x-coord value is not large.

1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        ro_fsys, not XSTRING (foo).

        * xterm.c (x_new_font): Reject fonts with varying spacing.  We
        don't support them yet.
        * xfns.c (x_set_font): Report the error message properly.

        * xfns.c (Fx_parse_geometry): No need to call check_x here; it
        doesn't interact with the server at all, and we need it in order
        to create our first frame.

        * s/dgux.h (NO_GET_LOAD_AVG): Define, if __GNUC__.

1993-05-23  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * s/hpux8.h (NO_SIOCTL_H): Defined.

1993-05-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/linux.h (HAVE_DUP2, HAVE_ALLOCA_H): Deleted.

1993-05-23  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * syssignal.h: Don't #include <signal.h>
        * alloc.c: #include <signal.h>, but before "config.h".

1993-05-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfaces.c (Fset_face_attribute_internal): Don't call unload_font
        for the frame's own font.

        * xfns.c (check_x): New function.
        Call it in almost every Lisp function in this file.
        (x_set_menu_bar_lines_1): Pass both args in recursive call.

1993-05-23  Paul Eggert  (eggert@twinsun.com)

        * editfns.c (Fcurrent_time_zone): Make `am' an int, not long.

1993-05-23  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        Changes for SGI from Matthew J Brown <mjb@doc.ic.ac.uk>.
        * m/iris4d.h, m/iris5d.h: Don't use the --cckr CC switch if we're
        using GCC.
        * m/iris4d.h (NEED_SIOCTL): Move this to...
        * s/irix3-3.h (NEED_SIOCTL): ... here; apparently it's not
        necessary in irix4-0.h.
        * s/irix4-0.h: Remove declaration of getpty; apparently Irix 4.0
        already declares this elsewhere.
        (PTY_TTY_NAME_SPRINTF): #undef this before re-#defining it.
        * m/ibmps2-aix.h, m/pfa50.h, s/hpux.h, s/isc2-2.h, s/linux.h,
        s/sco4.h, s/usg5-4.h: Remove HAVE_RENAME; configure guesses that now.

        * config.h.in (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Change the
        #defines to #undef's, so ../configure knows it should tweak them.

        * xterm.c (x_scroll_bar_report_motion): Set *TIME whether or not
        the mouse is over a scroll bar.

        * xfaces.c (Fset_face_attribute_internal): Don't free the frame's
        normal_gc or reverse_gc.

        * keyboard.c (make_lispy_movement): Deal properly with mouse
        motion outside of all windows.

        * lisp.h (GLYPH_FACE): Remember that the face portion of a glyph
        can be 24 bits, not just eight.

1993-05-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xterm.c: Move signal.h and stdio.h before config.h.

        * editfns.c (Fcurrent_time_zone): Assign gmt, instead of init.

1993-05-22  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * Version 19.7 released.

        * Makefile.in (SUBMAKEFLAGS): Add CFLAGS to the list.

        * puresize.h [not HAVE_X_WINDOWS] (PURESIZE): Make this 185k,
        not 196k.  We're actually using ~180k.

        * editfns.c: #include <sys/types.h>, to get time_t for Eggert's
        changes.

1993-05-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * ymakefile (FRAME_SUPPORT): Add mouse.elc, select.elc, scroll-bar.elc.

        * xdisp.c (display_text_line): Highlight in any frame's sel window.

        * keyboard.c (modifier_names): Update to match *_modifier in termhooks.

1993-05-22  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * xterm.c (x_scroll_bar_handle_click): Never grab the scroll bar;
        that feature requires more support to work correctly.

        * keyboard.c (make_ctrl_char): New function.
        (read_char): Call it.
        (kbd_buffer_store_event): Call it to see if the new character is
        the quit or stop character.
        (make_lispy_event): Call it.

1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfns.c (x_window_to_frame): Use XGCTYPE.

1993-05-21  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * process.c (Fopen_network_stream): Deal with older systems, which
        only have the h_addr field in their struct hostent.

        * systty.h [SYSV_PTYS]: #include <sys/types.h>.  Francesco
        Potorti` <pot@fly.CNUCE.CNR.IT> says it's necessary on his
        machine, and it should be harmless.

1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * sysdep.c (wait_for_termination): Copy code from 18.59
        (but sans BSD4_1 alternatives).

1993-05-21  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * ymakefile (alloca.o): #define malloc and free to be xmalloc and
        xfree on the command line of this compilation.

        * s/sco4.h: (TIME_WITH_SYS_TIME): This is no longer needed.

        * s/linux.h: Remove copyright notices by Michael K. Johnson and
        Rik Faith.  They have both sent in papers now which make their
        changes public domain.

        * sysdep.c (sys_suspend): Set synch_process_alive, so that
        wait_for_termination has something to wait for.

1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xdisp.c (display_text_line): Highlight only in selected window.

        * xfns.c (syms_of_xfns): Don't make Lisp vars
        x-mode-pointer-shape and x-nontext-pointer-shape.

        * s/sco4.h (SCO): Don't define (no longer needed).
        (HAVE_SYS_TIME_H): Don't define (set by configure).
        (TIME_WITH_SYS_TIME): Define.

1993-05-20  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * dispnew.c (preserve_other_columns): Remember to multiply the
        size argument to bcopy by the size of a glyph.

1993-05-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (read_key_sequence): Reexamine this_command
        after pre-command-hook runs.

        * xterm.c (x_find_modifier_meanings): If some keys are meta and alt,
        make them just meta, not alt.

1993-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        Some time-handling patches from Paul Eggert:
        * editfns.c (Fcurrent_time_zone): Take an optional argument specifying
        what (absolute) time should be used to determine the current time zone.
        Yield just offset and name of time zone, including DST correction.
        Yield time zone offset in seconds, not minutes.
        (lisp_time_argument, difftm): New functions.
        (Fcurrent_time_string): Use lisp_time_argument.
        * systime.h (EMACS_CURRENT_TIME_ZONE, EMACS_GET_TZ_OFFSET,
        EMACS_GET_TZ_NAMES): Remove.
        * config.h.in: Add HAVE_TM_ZONE.

        Some more changes from Michael K. Johnson for Linux.
        * s/template.h: Mention that you should #define HAVE_TERMIO or
        HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
        * systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
        tcsetpgrp to *pgid; it's just a status value.
        * config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
        systems using XFree386, and perhaps is inappropriate in general.
        * m/intel386.h: #undefine the integer size macros, since the Linux
        <values.h> file #defines them itself.
        * mem-limits.h (get_lim_data): Linux has the ulimit call; if it
        fails, fall back on ULIMIT_BREAK_VALUE.
        * process.c: Linux needs the WAITTYPE, etc. definitions.
        * unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
        no need to use SYSV names.
        * s/linux.h: New file.

        Some changes from Michael K. Johnson for Linux.
        * sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
        #defined.  That lets the system provide it, if it has it.
        * syssignal.h (sigmask): Only define this if <signal.h> hasn't
        given us a definition already.
        * syssignal.h (sys_sigpause): Fix argument in prototype.
        * sysdep.c (init_signals): The masks are called empty_mask and
        full_mask, not signal_empty_mask and signal_full_mask.
        (signal_handler_t): Moved ....
        * syssignal.h: ... to here.
        * systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct
        arguments.
        * emacs.c (main): Don't try to establish signal handlers for
        SIGBUS and SIGSYS unless they're actually #defined.

        * systty.h [HAVE_TERMIO, __DGUX]: #include <sys/ioctl.h>.

        * xdisp.c (redisplay_window): Compute the scrollbar start and end
        properly.

1993-05-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (Fcurrent_input_mode): Return META as 3-way flag.

1993-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * fileio.c (Ffind_file_name_handler): Check that FILENAME is a
        string.

        * process.c (wait_reading_process_input): Undo change of April
        29th, since that re-introduces the race condition the comments are
        warning about.  Call clear_waiting_for_input before calling
        status_notify, though.

        * process.c (wait_reading_process_input): Don't forget to call
        clear_waiting_for_input when we exit the loop because process
        input has arrived.

        Changes for Silicon Graphics Iris 5D.
        * unexelfsgi.c: New file; like unexelf.c, but tolerates program
        segments above BSS. 
        * m/iris5d.h: New file.
        * s/irix5-0.h: New file.
        * process.c [__sgi] (allocate_pty): Give up immediately if pty is
        inaccessible.

1993-05-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (follow_key): Check char in range before UPPERCASEP.

1993-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfns.c (x_set_menu_bar_lines): Fix typo in last change.

        * keyboard.c (make_lispy_event): Controlify lower case letters too.

1993-05-18  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xdisp.c (display_text_line): If the newline (or C-m, in
        selective-display) has a non-default face, apply that face to the
        remainder of the line, so that the fill occupies the entire line.

        * xterm.c (x_new_font): Tell the frame display faces about the
        newly chosen font.

        Make sure that all the display faces use fonts of the
        same dimensions as the default face, so as not to confuse the rest
        of the redisplay code.
        * xfaces.c (same_size_fonts): New function.
        (merge_faces): Only merge in a new font from the FROM face if it
        is the same size as the font in the TO face.

        * xfns.c (x_set_menu_bar_lines): Minibuffer-only frames can't have
        menu bars.

        * keyboard.c (read_key_sequence): Don't lay down an unwind_protect
        to restore the original buffer until we actually get a mouse click.

        * window.c (window-dedicated-p): Doc fix.

1993-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xterm.c (XTread_socket): Turn off ControlMask for XLookupString.
        * keyboard.c (make_lispy_event): Controlify here.

1993-05-17  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * xdisp.c (redisplay_window): Make the scrollbar reflect the
        extent of the visible region, not the whole buffer.

        * xfaces.c (free_frame_faces): Don't free the resources from the
        first two faces.

        * lisp.h (malloc, realloc): Declare these to return void *, to
        avoid conflicts with ANSI header files.

        * sysdep.c (reset_sys_modes): Test the return value of
        EMACS_SET_TTY properly.
        * systty.h (EMACS_GET_TTY, EMACS_SET_TTY): Document the return
        values.

1993-05-16  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * config.h.in (STDC_HEADERS, TIME_WITH_SYS_TIME,
        CRAY_STACKSEG_END, STACK_DIRECTION): Add #undef clauses for these,
        since otherwise the autoconf tests in configure.in won't do us
        much good.

1993-05-16  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * buffer.c (overlays_at): New arg EXTEND.
        (Foverlays_at, Fnext_overlay_change): Pass 1.
        * xfaces.c (compute_char_face): Pass 0.
        Try first with small overlay_vec, then use a big enough one.

        * lread.c (syms_of_lread): Make Vcurrent_load_list ordinary Lisp var.
        Set up Qcurrent_load_list.
        (readevalloop): Specbind Qcurrent_load_list instead of ad-hoc saving.
        (build_load_history): Do nothing when loading pure files.

        * xterm.c (dumpglyphs): Create a temporary merged gc
        when cursor falls on char with non-default face.

1993-05-15  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * xfaces.c (Fset_face_attribute_internal): Jolt redisplay, so it
        knows something has changed.

        * xfaces.c (unload_color): Don't try to unload the standard black
        or white pixel.

        More changes from David Mackenzie.
        * ymakefile (emacs): No need to edit srcdir into a lisp file and
        then load it; we can just take advantage of the PATH_DUMPLOADSEARCH.
        (crt0.o): Remember that crt0.c is in ${srcdir}.

        Install David Mackenzie's patches to make ${srcdir} work.
        * Makefile.in (srcdir, VPATH): Get this value from the top-level
        Makefile.
        (xmakefile): Use ${srcdir} to find the files from which we produce
        xmakefile.  Edit the values for srcdir and VPATH into xmakefile.
        * ymakefile (srcdir, VPATH): New definitions for the Makefile
        to edit.
        (ALL_CFLAGS): Remove `-Is' and `-Im'; add `-I${srcdir}', and
        `-I.'.
        (emacs): Adjust dumping commands to deal with a separate source
        directory.
        (${etc}DOC): Pass `-d ${srcdir}' to make-docfile, to tell it where
        to find the source files.
        (prefix-args): Find the source code in ${srcdir}.

        * process.c (wait_reading_process_input): If we're running
        Solaris, it's not necessary to check if we should redeliver SIGIO,
        according to David Mackenzie.
        * s/sol2.h: #include "usg5-4.h", and #define const.

        * systime.h: Borrow CPP sequence from getdate.y to include the
        proper combination of <time.h> and <sys/time.h>.

1993-05-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * window.h (struct window): New slot region_showing.
        * xdisp.c (mark_window_display_accurate): Set region_showing fields.
        (redisplay_window): Update region_showing field.
        (display_text_line): Set region_showing to t if will show one.

        * xselect.c (Fx_selection_exists_p): Handle nil, t as SELECTION arg.
        Don't die if SELECTION is not recognized.

        * dispnew.c (direct_output_forward_char): Just give up
        if region is being highlighted.

        * xdisp.c (redisplay, redisplay_window): Don't use the cursor-motion
        special-case code if the region is or was highlighted.
        
        * xfaces.c (compute_char_face): New args REGION_BEG, REGION_END.
        Don't sort if noverlays is 0 or 1.

        * dispnew.c (direct_output_for_insert): Pass those args.
        * xdisp.c (display_text_line): Pass those args,
        describing the region if the mark is transient and active.

1993-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * buffer.c (Fmove_overlay): If the overlay is in no buffer and the
        BUFFER argument has been omitted, put it in the current buffer,
        for symmetry with move-marker.

        * buffer.c (Fdelete_overlay): Make the overlay's markers point
        nowhere, not at 1.  Do this after calling redisplay_region, so
        that code knows what section has changed.

1993-05-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xdisp.c (display_menu_bar): Update FRAME_MENU_BAR_ITEMS here.
        * keyboard.c (command_loop_1): Don't do it here.

        * keymap.c (access_keymap): Handle any length vector.
        (store_in_keymap): Likewise.
        (Fcopy_keymap): Likewise.

1993-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * buffer.c (Foverlay_start, Foverlay_end, Foverlay_buffer,
        Foverlay_properties): Functions moved here from subr.el.

1993-05-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * xfaces.c (compute_char_face): When merging the overlays,
        traverse sortvec, not overlay_vec; the latter isn't the one we
        sorted.

        * xterm.c (dumpglyphs): Give the cursor higher priority than the
        face specified by the glyph under it.

        * xterm.c (dumpglyphs): Move the underline up a row.  I dislike
        the way X addresses pixels.  Quickdraw is much nicer.

        * xfaces.c (intern_face): If the face has a GC, but it's not the
        default or modeline face, abort.  Nothing but those two faces
        should have a GC *and* be passed to intern_face.
        (compute_char_face, compute_glyph_face): After copying
        the frame's default face into face, to use as a base case for
        calculation, set the `gc' member to zero; that way we don't have
        things lying around that look like display faces but aren't.

        * xfaces.c (intern_frame_face): When copying the new face into the
        frame's face array, remember that the number of bytes to copy is
        sizeof (*new_face), not sizeof (new_face).

        * xfaces.c (compute_char_face): Assume that W is displaying the
        current buffer.  Abort if it isn't.

        * lisp.h (Lisp_Overlay): New tag.
        (OVERLAYP): New predicate.
        (CHECK_OVERLAY): New type-checker.
        (Qoverlayp): New extern declaration.
        * buffer.c (Foverlayp): New function.
        (Qoverlayp): New atom.
        (overlays_at, recenter_overlay_lists): Abort if we encounter an
        invalid overlay.
        (syms_of_buffer): defsubr Soverlayp; initialize Qoverlayp.
        (Fdelete_overlay): Set the overlay's markers to point nowhere.
        Use CHECK_OVERLAY instead of signalling a special error.
        (Fmove_overlay, Foverlay_put): Use CHECK_OVERLAY instead of
        signalling a special error.
        (Foverlay_get): Use CHECK_OVERLAY.
        * fns.c (internal_equal): Define this for overlays.
        * buffer.h (OVERLAY_VALID): Define in terms of OVERLAYP.
        * print.c (print): Give overlays their own print syntax.
        * alloc.c (mark_object): Treat overlays like conses.

        * lisp.h (FLOATP): Define this appropriately when LISP_FLOAT_TYPE
        is not defined.

        * buffer.c (Foverlay_get): Return Qnil if the requested property
        is missing from the property list.

        The text property routines can now modify buffers other
        than the current one.
        * insdel.c (modify_region): New argument BUFFER.  Select that
        buffer while we prepare for the modification, and switch back when
        we're done.
        * textprop.c (add_properties, remove_properties): Pass
        the buffer being modified as the first argument to modify_region.
        * editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
        current_buffer as the first argument to modify_region.
        * casefiddle.c (casify_region): Same.

        * dispnew.c (direct_output_for_insert): Compute the face of the
        character we're inserting properly.

        * xterm.c (dumpglyphs): Pass the proper arguments to intern_face.

        * xterm.c (dumpglyphs): Don't increment left twice.

        * intervals.c (set_point): Check for point out of bounds before
        checking for an empty interval tree. 

        * cmds.c (Fforward_char): Check proposed new position, and then
        set point, instead of setting point to a potentially invalid
        position.

        * lread.c, data.c: If STDC_HEADERS is #defined, include <stdlib.h>
        to get the extern declarations for atof.  That's where it is in
        POSIX.

1993-05-12  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * ymakefile (xfaces.o): Add window.h to the dependencies.

        * xfaces.c (intern_frame_face): Exchange order of arguments, to
        make callers correct.

        * xfaces.c (compute_char_face): Notice the next property change
        location correctly.

        * xfaces.c (face_name_id_number): Return 0 (the default face) if
        the name is undefined.

        * xfaces.c (Fset_face_attribute_internal): Do nothing unless FRAME
        is an X frame.

        * xdisp.c (copy_rope, copy_part_of_rope): Add face argument.
        (display_text_line): Initialize current_face to zero.   Apply it
        to characters as we write them to the display matrix.
        (display_string): Pass the new argument to copy_rope.

        * xdisp.c (display_text_line): Handle the locations of face
        changes properly.

        * textprop.c (Fnext_single_property_change,
        Fprevious_single_property_change): Pass arguments to textget in
        the right order.

        * ymakefile (xfns.o): Remove duplication of buffer.h in dependencies.

        * ymakefile ($(OLDXMENU)): Remove extraneous call to `rm'.

1993-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keymap.c (Faccessible_keymaps): Use whatever size the vector has.
        (Fwhere_is_internal): Likewise.
        (describe_vector): Likewise.
        (current_minor_maps): Call Findirect_function, so symbols
        can be used in place of actual maps.

        * xdisp.c (display_text_line): Use break; to exit loop at eol.
        Duplicate the short MAKE_GLYPH loop after the main loop.
        If no display table, do obey selective_display_ellipses.
        (copy_part_of_rope): Arg FROM is now Lisp_Object *.

        * xfaces.c: Do include window.h.
        (compute_char_face): Supply third arg of Fget_text_property.

        * keyboard.c (make_lispy_event): Don't set shift modifier for C-^.

        * callproc.c (child_setup): Omit duplicates from new env array.

1993-05-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * fileio.c (ro_fsys) [SOLARIS_BROKEN_ACCESS]: Check for the
        filesystem being ro, since Solaris 2.1 doesn't.
        (file-writable-p): Call ro_fsys.
        * s/sol2.h (SOLARIS_BROKEN_ACCESS): Define this.

        * systime.h: Use the strategy from getdate.y to include the proper
        combination of <time.h> and <sys/time.h>.

        * xfns.c (Fx_create_frame): Use an XLFD name for the default font,
        instead of "9x15" or whatever it was.

        * xdisp.c (display_text_line): Make face-handling code conditional
        on HAVE_X_WINDOWS macro.  Perhaps this isn't the best approach,
        but it'll do for now.

        * xdisp.c (display_text_line): We can't use the FRAME_DEFAULT_FACE
        macro here; that's x-specific.  Just don't pass the second
        argument.
        * xfaces.c (compute_glyph_face): Remove the BASIC_FACE argument;
        use F's default face.

1993-05-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * xfaces.c (Fmake_face_internal): Do nothing for non-X frames.

        * dispextern.h (struct face): Add cached_index member.
        * xfaces.c (get_cached_face): Use it to avoid unnecessary
        searches of face_vector.

        * xfaces.c (intern_face): Renamed from get_display_face.

        * xfns.c (x_make_gc): After building the GC's for the frame, call
        init_frame_faces to set up the first two faces.
        * xfaces.c (init_frame_faces): Don't just try to copy the default
        and mode line faces from some other random frame; instead, consult
        the normal_gc and reverse_gc members of the frame, and build the
        faces based on their parameters.

        Adjust the face computation functions to return frame face ID's,
        not pointers to display faces; since we call these functions
        during display construction, we don't want the display faces yet.
        * xfaces.c (intern_frame_face): New function.
        (compute_char_face, compute_glyph_face): Apply intern_frame_face
        to the computed face, and return the frame face's ID, instead of
        calling intern_face and returning a pointer to a display frame.

        * xfaces.c: Describe the facial data structures.  It took me a
        while to figure them out; perhaps this will save someone else the
        trouble.

        Arrange to tell redisplay about changes in overlays.
        * xdisp.c (redisplay_region): New function.
        * buffer.c (Fmove_overlay): Call redisplay_region on the areas the
        overlay has enclosed or left.
        (Fdelete_overlay): Call redisplay_region on the area the overlay
        used to occupy.
        (Foverlay_put): Call redisplay_region on the area the overlay now
        occupies; we may have put a face property on it.

        * buffer.c (Fmove_overlay): Doc fix.

        * xdisp.c (redisplay): If we're doing a thorough redisplay (all
        windows on all frames involved), go ahead and flush the GC cache -
        call clear_face_vector.

        * xdisp.c (display_text_line): Apply faces to characters
        according to overlays and text properties; use
        compute_char_face and compute_glyph_face to figure out what
        face to use, and where a new face starts.
        * xterm.c (dumpglyphs): Use the upper bits of the glyphs to decide
        which frame face to use.  Call GLYPH_FOLLOW_ALIASES to make sure
        we're implementing the glyph table properly.  If we're not using
        the default or mode line face, call intern_face to find a display
        face for the frame face selected by the glyph code.  Implement
        underlining.  Remove the `font' argument; we have to derive this
        from the frame and face anyway.  Change all callers.
        * disptab.h (GLYPH_FOLLOW_ALIASES): New macro.

        * xterm.c (x_destroy_window): Call free_frame_faces.

        The GNU coding standards specify that CFLAGS should be left for
        users to set.
        * ymakefile (ALL_CFLAGS): Set this to the long string of
        compilation switches, not CFLAGS.  Changed all uses.
        (CFLAGS): Make this default to just -g.
        (.c.o): Define new default rule, to make sure that the right flags
        get to the compilations.

1993-05-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (read_char): Exit kbd macro if Vexecuting_macro is t.

        * pwd.h: File deleted.

1993-05-08  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * s/sunos4shr.h: Apply changes from David J. Mackenzie; this isn't
        used by any configuration right now, but he's trying to make it
        work.
        #include "sunos4-1.h" instead of "bsd4-2.h".
        (O_NDELAY): Don't define this.
        (SYSTEM_MALLOC): Don't define this, either.
        (LD_SWITCH_SYSTEM): Remove the definition for this.

        * Makefile.in (DEFS): Remove this; we have configure build a
        config.h file directly, instead of having lots of -D flags.

        * Makefile.in (CFLAGS): Don't make this carry DEFS from the
        configure script; the coding standards say that CFLAGS should be
        left for the user to tweak.

1993-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (do_mouse_tracking): Now static.

        * xmenu.c (Fx_popup_menu): Add a vector of prefix keys for the panes.
        (keymap_panes): Allocate that vector.
        (single_keymap_panes): Fill in that vector.
        (xmenu_show): Return a list of events, not just one event.

        * keyboard.c (read_char_menu_prompt): Expect Fx_popup_menu
        to return a list of events.  Don't lose any of them.

        * xfns.c (Fx_get_mouse_event, Fx_mouse_events): Code deleted.
        * window.c (Vmouse_event): Var deleted.
        (syms_of_window): Don't make it a Lisp var.

        * keyboard.c (read_avail_input, Fset_input_mode): Make
        meta_key a three-value variable to support 8-bit input.

1993-05-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * ymakefile [__GNUC__ && __GNUC__ > 1] (LIB_GCC): Set this even if
        LINKER is #defined.

        * ymakefile ($(OLDXMENU)): Remove the link before we re-create it;
        not all versions of ln have the `-f' flag.  Use the LN_S variable,
        inherited from src/Makefile.

        * Makefile.in (LN_S): New variable, edited by top Makefile.
        (SUBMAKEFILE): New variable, containing all flags to pass to
        recursive makes.

        * config.h.in: Adjust this for use by autoconf's AC_CONFIG_HEADER,
        instead of AC_OUTPUT.

        * xfaces.c (get_display_face): Use face_eql instead of writing it out.

1993-05-06  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * keymap.c (Fwhere_is_internal): If FIRSTONLY is non-nil, avoid
        returning a non-ascii key sequence unless FIRSTONLY is the symbol
        `non-ascii'.

        * config.h.in: Remove mention of GLYPH datatype; that shouldn't be
        a user option.
        * lisp.h (GLYPH, MAKE_GLYPH, GLYPH_CHAR, GLYPH_FACE): New macros.

1993-05-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfns.c (x_get_arg): Call Fintern, not intern.

        * systime.h [SCO]: Include time.h.
        * s/sco4.h: New file.

        * ymakefile (LIBXMENU): Delete -loldX.

        * emacs.c (main): Handle -display like -d.

1993-05-05  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * s/template.h: Explain the relative significance of the SIGIO and
        INTERRUPT_INPUT macros.

        * ymakefile (buffer.o, insdel.o): Note that these files also
        depend on blockinput.h.

        * blockinput.h (UNBLOCK_INPUT): We cannot assume that SIGIO is
        defined everywhere this file is #included; merge the two
        definitions for defined (SIGIO) and ! defined (SIGIO) into one,
        which calls reinvoke_input_signal if interrupt_input_pending is
        set.
        * keyboard.c (reinvoke_input_signal): New function.

1993-05-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * window.c (Fdisplay_buffer): Add space to prompt.

1993-05-04  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * keyboard.c (syms_of_keyboard): Doc fix for
        extra-keyboard-modifiers.

        * lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER, CHAR_SHIFT, CHAR_CTL,
        CHAR_META): Shift these all up one bit, back to where they were.

1993-05-02  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * keymap.c (Fdefine_prefix_command): Doc fix.

        * ymakefile (C_DEBUG_SWITCH): Undo April 10 change.

1993-05-01  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (Fsuspend_emacs): Doc fix.

1993-04-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * data.c (Ffset): Refuse to set the function value of t or nil.

1993-04-29  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        Implement extra_keyboard_modifiers properly.
        * keyboard.c (syms_of_keyboard): Doc fix for
        extra-keyboard-modifiers; use the same modifier bits as we do for
        characters.
        (read_char): Apply all the modifiers in extra_keyboard_modifiers
        to the input characters, so you can get hyper, super, and the rest
        of the gang.
        * xterm.c (x_emacs_to_x_modifiers): New function.
        (x_convert_modifiers): Renamed to x_x_to_emacs_modifiers, for
        consistency.  Callers changed.
        (XTread_socket): Apply x_emacs_to_x_modifiers to
        extra_keyboard_modifiers before setting the state member of the
        event; this will get all the modifiers on ASCII characters.

        * xterm.c (x_text_icon): Don't call XSetIconName; it should be
        unnecessary, and perhaps it's killing the icon pixmap.

        * lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER): New constants, in
        case we need them.
        * termhooks.h (alt_modifier, super_modifier, hyper_modifier,
        shift_modifier, ctrl_modifier, meta_modifier): Define these in
        terms of the CHAR_mumble macros, to avoid having the same thing
        defined in two places.

        * keyboard.c (kbd_buffer_get_event): Don't generate switch-frame
        events if they'd only switch to the frame already selected.  This
        avoids lots of extra switch-frame events when using a separate
        minibuffer.

1993-04-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (Fthis_command_keys): Doc fix.

        * process.c (wait_reading_process_input): Move the status_notify
        call before the set_waiting_for_input call.

        * fileio.c (Fexpand_file_name): Undo last change--too risky for now.

        * data.c (Fdefine_function): New function (same code as Fdefalias).

1993-04-28  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

        * eval.c (do_autoload): Fixed the bug in the autoload-saving code.

1993-04-28  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * keyboard.c (Fcurrent_input_mode): New function.

1993-04-27  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

        * eval.c (un_autoload): Don't try to save old autoload forms when
        we load something in.  Something about the code now conditioned
        out by UNLOAD was screwing up ordinary autoloads, notably of
        picture.el.  When I figure out what, I'll fix and re-enable this
        code.

1993-04-27  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * buffer.c (syms_of_buffer): Doc fix for buffer-display-table.

        * systime.h: Doc fix.
        (EMACS_SET_USECS): Remember that a `usec' is a microsecond, not a
        millisecond.  What's three orders of magnitude between friends?
        * dispnew.c (Fsit_for, Fsleep_for): Remember to multiply the
        `milliseconds' argument by 1000 to get microseconds.

1993-04-26  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * fileio.c (Fexpand_file_name):
        Don't remove trailing / from NEWDIR if just "/".

1993-04-26  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * m/ibmps2-aix.h, m/ibmrs6000.h, m/ibmrt-aix.h, m/mips.h,
        m/sps7.h, s/hpux.h, s/usg5-4.h (HAVE_DUP2): Removed; derived by
        configure script.
        * s/hpux.h, s/irix3-3.h, s/aix3-1.h (HAVE_GETHOSTNAME): Removed;
        derived by configure script.

        Arrange for Fy_or_n_p to put off switch-frame events.
        * lread.c (read_filtered_char): New function, which contains the
        code which used to be in Fread_char, Fread_event, and
        Fread_char_exclusive; there was a lot of common code.
        (Fread_char, Fread_event, Fread_char_exclusive): Rewrite in terms
        of read_filtered_char.
        * lisp.h (read_filtered_char): Declare this extern here.
        * fns.c (Fy_or_n_p): Call read_filtered_char, arranging to delay
        switch-frame events.

        * keyboard.c (read_key_sequence): Let the `modifiers' variable in
        the code which deals with KEY being unbound be an int, not a
        Lisp_Object.

        * config.h.in (getenv): Don't test THIS_IS_YMAKEFILE to see if we
        should exclude the getenv declaration; instead, test NOT_C_CODE.
        Per suggestion from Francesco Potorti`.
        * ymakefile (NOT_C_CODE): Define this; it's true, and useful.

        * dispnew.c (Fsleep_for, Fsit_for): Allow SECONDS to be a
        floating point value.

1993-04-26  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

        * sysdep.c (read_pending_input):
        Fix the garbaged-modifiers bug under System Vs previous
        to r4.

1993-04-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * systty.h (EMACS_GET_TTY, EMACS_SET_TTY): Move these into
        functions in sysdep.c.
        * sysdep.c (emacs_get_tty, emacs_set_tty): Here they are.

        * sysdep.c (emacs_set_tty): Call tcsetattr over and over again
        until it does all of what we ask it to, or returns an error.

        * search.c (Freplace_match): Arrange for markers sitting at the
        beginning or end of the original text to float to the
        corresponding position in the replacement text.

1993-04-25  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

        * window.c (Fset-window-buffer):
        Set horizontal-scrolling on a window to zero when
        we connect it to a new buffer.

        * buffer.c: Doc fix.

1993-04-24  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        Make the modifier manipulation functions more robust.  The old way
        caused a bug once, and probably would again.
        * termhooks.h (alt_modifier, super_modifier, hyper_modifier,
        shift_modifier, ctrl_modifier, meta_modifier): Shift these all
        down one bit in value, to avoid sign extension problems.
        * lisp.h (CHAR_META, CHAR_CTL, CHAR_SHIFT): Fix these definitions too.
        * keyboard.c (lispy_modifier_list): Ignore modifier bits beyond
        what our table of modifier names can handle.
        (apply_modifiers): Don't abort if you see extra modifier bits,
        just remove them.

1993-04-23  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

        * data.c (Fdefine_function):
        Changed name back to Fdefalias, so we get things
        in a known-good state.

        * buffer.h (BUF_NARROWED, NARROWED):
        New macros to test whether a region
        restriction has narrowed the buffer.

1993-04-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * systime.h: Comment fixes.

        * data.c (Fdefine_function): New function.

        * lisp.h (LOADHIST_ATTACH): New macro.
        (Vcurrent_load_list, Vload_history): Vars declared.

        * eval.c: (defun, defmacro, defvar, defconst):
        Attach symbol argument to the list of globals for the input source.
        (do_autoload): Save the old autoloads, in case we ever unload.

        * fns.c (provide, require): Put appropriately-marked
        conses in the current-globals list.

        * lread.c (readevalloop):
        New argument is the source file name (or nil if none).
        All calls changed.  Do the two-step
        necessary to call build_load_history with the correct current-globals
        list for the current recursion.
        (build_load_history): New function.
        (eval_region, eval_buffer): Call readevalloop with new arg.
        (load_history): New variable.

1993-04-16  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

        * lread.c (readevalloop): New argument is the source file name (or
        nil if none).  All calls changed.  Do the two-step
        necessary to call build_load_history with the correct current-globals
        list for the current recursion.
        (build_load_history): New function.
        (Feval_region, Feval_buffer): Call readevalloop with new arg.
        (Vload_history): New variable.

        * fns.c (Fprovide, Frequire): Put appropriately-marked
        conses in the current-globals list.

        * eval.c (Fdefun, Fdefmacro, Fdefvar, Fdefconst):
        Attach symbol argument to the list of globals for the input source.
        (do_autoload): Save the old autoloads, in case we ever unload.

        * data.c (Fdefine_function): New function.

1993-04-16  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * fileio.c (Fmake_symbolic_link): If a file already exists under
        the link's filename, delete the file which the link
        would replace, not the file the link would point at.

        * config.h.in (volatile): Don't define this to be the empty string
        if some file has #defined HAVE_VOLATILE.

        * emacs.c (SEPCHAR): Instead of defining this to be ',' on VMS and
        ':' elsewhere, just have it default to ':' if not #defined, and
        #define it to be ',' in s/vms.h; OS/2 will need it to be ';'.
        * s/vms.h (SEPCHAR): #define this to be ','.
        * s/template.h (SEPCHAR): Mention this.

1993-04-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * s/vms.h (xfree): #define this to emacs_xfree, to avoid case
        conflict with XFree; on VMS, external symbols are case-insensitive.

        * s/usg5-4.h (HAVE_GETTIMEOFDAY): Deleted; ../configure figures
        that out now.

        Changes for Emacs 19 from Thorsten Ohl <ohl@chico.harvard.edu>:
        * s/mach2.h: copied from the Emacs 18.59 distribution.
        Don't define NO_REMAP, define START_FILES as
        `pre-crt0.o' instead.  Define LIB_MATH as `-lm', to override the
        default `-lm -lc' (there is no libc on the NeXT).
        * ymakefile (STARTFILES): Allow config.h to set this value even if
        ORDINARY_LINK is defined.
        * unexnext.c: Fix subdirectories for the machine dependent include
        files for NeXTStep 3.0; #include <mach/mach.h> and
        <mach-o/loader.h> instead of <mach.h> and <sys/loader.h>.
        (getsectbyname): Remove prototype for this; the system #include
        files take care of that.
        (malloc_cookie): New variable.
        (unexec_doit): Set malloc_cookie to the result returned by
        malloc_freezedry.
        * emacs.c (main): Declare malloc_cookie to be extern, so that we can
        get the value set when we dumped and pass it to malloc_jumpstart.
        * systime.h: The NeXT has a timezone function.

1993-04-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * ymakefile ($(OLDXMENU)): Remove $(OLDXMENU) before trying to
        link in a new version.

        * lisp.h (Qrange_error, Qdomain_error, Qsingularity_error,
        Qoverflow_error, Qunderflow_error): Add extern to these declarations.

1993-04-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfaces.c: Don't include Xmu/Drawing.h.

1993-04-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * Makefile.in (xmakefile): Recognize the -O option with a numeric
        optimization level.

        * ymakefile (C_DEBUG_SWITCH): If we're using version 2 of GCC or
        higher, use -O99 instead of plain -O.

1993-04-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * keyboard.c (command_loop_1): Rebuild menu bar if
        update_mode_lines is set.

        long_to_cons and cons_to_long are generally useful things; they're
        needed whether or not X is defined.
        * xselect.c (long_to_cons, cons_to_long): Moved from here...
        * data.c    (long_to_cons, cons_to_long): ... to here.
        * lisp.h    (long_to_cons, cons_to_long): Add extern declaration.

        * xmenu.c (Qmenu_enable): Definition moved...
        (syms_of_xmenu): ... along with initialization ...
        * keyboard.c (Qmenu_enable): ... to here ...
        (syms_of_keyboard): ... and here.

        * keyboard.c (kbd_buffer_get_event): If we get a selection clear
        or selection request event, but we were compiled without the
        window-system-specific code to handle it, abort.  Don't try to
        call a function which doesn't exist.

        * keyboard.c (make_lispy_event): In the code which processes mouse
        clicks, declare f to be a FRAME_PTR, not a struct frame *; this
        works when MULTI_FRAME is not #defined.

        * xfaces.c (sort_overlays): Define this to be static, as declared.

        * callproc.c (relocate_fd): Make messages string literals, not
        initialized arrays.

        * alloc.c (__malloc_hook, __realloc_hook, __free_hook): Declare
        these extern, not static.  (!)

        * alloc.c (__malloc_hook, old_malloc_hook, __realloc_hook,
        old_realloc_hook): Declare that the functions these point to return
        void *, not void.

        Adjust for autoconf merger.
        * config.h.in: Add extra line to top, in case autoconf gets fixed
        and decides not to add Makefile-style comments to the top of the
        files it generates which we are forced to lop off.
        Indicate that the boolean macros here get their definitions via
        the DEFS Makefile variable.
        Adjust the operating system and machine #includes to use
        autoload's @cookies@.
        (RETSIGTYPE): Give this a default value.
        (SIGTYPE): Set this from RETSIGTYPE.
        (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Get values via @cookies@.
        * Makefile.in (DEFS): Renamed from CONFIG_CFLAGS.
        (xmakefile): Pass CFLAGS to ${CPP}.

        * buffer.c (Fmake_overlay, Fmove_overlay): New optional BUFFER
        arguments.
        (recenter_overlay_lists): New argument BUF, to use instead of the
        current buffer.
        (Foverlay_recenter): Pass the appropriate arguments to
        recenter_overlay_lists.

        * buffer.c (Fdelete_overlay): Don't assume that overlay is in the
        current buffer.  Don't forget to declare the argument a Lisp_Object.

        * dispnew.c (getenv): Extern declaration deleted; this is done in
        config.h.

        * Makefile.in (tagsfiles): Remove external-lisp from this list of
        files; we're not distributing it, so the normal build process
        shouldn't depend on it.

        * dispnew.c (init_display): Compare the return value of getenv to
        zero before setting display_arg, instead of just using the pointer
        as a truth value.

1993-04-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xdisp.c (message, message1): If noninteractive and
        cursor_in_echo_area, don't print a newline at end of message.

        * fns.c (Fy_or_n_p): Echo the answer just once, at exit.

        * keyboard.c (echo_dash): Do nothing if echoptr is 0.

        * buffer.c (Fkill_all_local_variables): Store each var's current value
        in the buffer's alist entry, before reverting to the default value.

1993-04-07  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * keyboard.c (apply_modifiers): Fix typo in sanity check.

        * keyboard.c (interrupt_input_blocked, interrupt_input_pending):
        Remove `extern' keywords - these are the definitions.

1993-04-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * blockinput.h (UNBLOCK_INPUT): Fix typo.
        (interrupt_input_blocked): Make this signed int.

        * search.c (search_buffer): Fix typo in previous change.

        * insdel.c, buffer.c: Include blockinput.h.

        * xterm.c: Fix typo in comment delimiter.

1993-04-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * m/imbrs6000.h: If we're using GCC, define ORDINARY_LINK instead
        of defining LINKER to use cc.
        * s/aix3-1.h (LINKER): Don't use cc for linking command if we're
        using GCC.
        * s/aix3-2.h (SYSTEM_MALLOC): Undefine this.

        * xterm.c (updating_frame): Declare this extern instead of static,
        so it's the same variable as the updating_frame in term.c.
        (XTupdate_begin, XTupdate_end): Don't bother to set
        updating_frame; the term.c functions take care of that for us.

1993-04-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * s/vms.h (EXEC_SUFFIXES): Add definition for this.

1993-03-31  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * xfaces.c: Doc fixes.

        Put interrupt input blocking in a separate file from xterm.h.
        This isn't specific to X, and it allows us to avoid #including
        xterm.h in files that don't really have anything to do with X.
        * blockinput.h: New file.
        * xterm.h (BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT,
        UNBLOCK_INPUT_RESIGNAL): These are now in blockinput.h.
        (x_input_blocked, x_pending_input): Deleted; there are analogs
        in blockinput.h called interrupt_input_blocked and
        interrupt_input_pending.
        * keyboard.c (interrupt_input_blocked, interrupt_input_pending):
        New variables, used by the macros in blockinput.h.
        * xterm.c: #include blockinput.h.
        (x_input_blocked, x_pending_input): Deleted.
        (XTread_socket): Test and set interrupt_input_blocked and
        interrupt_input_pending instead of the old variables.
        * alloc.c, xfaces.c, xfns.c, xmenu.c, xselect.c, keymap.c:
        #include blockinput.h.
        * eval.c: #include blockinput.h instead of xterm.h.
        * keyboard.c: #include blockinput.h.
        (input_poll_signal): Just test
        interrupt_input_blocked, instead of testing HAVE_X_WINDOWS and
        x_input_blocked.

        Block the processing of interrupt input while we're manipulating the
        malloc heap.
        * alloc.c: (xfree): New function, to make it easy to free things
        safely.
        (xmalloc, xrealloc): Block X input while doing the deed.
        (VALIDATE_LISP_STORAGE, gc_sweep, compact_strings): Use xfree

        * emacs.c [not SYSTEM_MALLOC] (main): Call uninterrupt_malloc
        on startup.
        * alloc.c: (make_interval, make_float, Fcons, Fmake_vector,
        Fmake_symbol, Fmake_marker, make_uninit_string, Fgarbage_collect):
        Use xmalloc instead of malloc; don't bother to check if out of
        memory here.
        (Fgarbage_collect): Call xrealloc instead of realloc.
        * buffer.c: Use xmalloc and xfree instead of malloc and free;
        don't bother to check if out of memory here.
        (Fget_buffer_create): Put BLOCK_INPUT/UNBLOCK_INPUT pair around
        calls to ralloc routines.
        * insdel.c: Same.
        * lisp.h (xfree): New extern declaration.
        * xfaces.c (xfree): Don't #define this to be free; use the
        definition in alloc.c.
        * dispnew.c, doc.c, doprnt.c, fileio.c, lread.c, term.c, xfns.c,
        xmenu.c, xterm.c: Use xfree instead of free.
        * hftctl.c: Use xfree and xmalloc instead of free and malloc.
        * keymap.c (current_minor_maps): BLOCK_INPUT while calling realloc
        and malloc.
        * search.c: Since the regexp routines can malloc, BLOCK_INPUT
        while runing them.  #include blockinput.h.
        * sysdep.c: #include blockinput.h.  Call xfree and xmalloc instead
        of free and malloc.  BLOCK_INPUT around routines which we know
        will call malloc.
        
        ymakefile (keyboard.o, keymap.o, search.o, sysdep.o, xfaces.o,
        xfns.o, xmenu.o, xterm.o, xselect.o, alloc.o, eval.o): Note that
        these depend on blockinput.h.

        * keyboard.c (parse_modifiers, apply_modifiers): Make sure we're
        not trying to create modifier masks using integers which are
        unrepresentable as lisp values.

1993-03-30  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        New macros NULL_DEVICE and EXEC_SUFFIXES, to give the name of the
        equivalent of /dev/null, and the suffixes used by executable
        files.  This is simple, and helps people porting Emacs to other
        operating systems.
        * process.h (NULL_DEVICE): Give this a default value.
        * process.c (Fstart_process): Pass EXEC_SUFFIXES to openp.

        * s/vms.h (NULL_DEVICE): #define this.

        Rename int-to-string to number-to-string, since it can handle
        floating-point as well as integer arguments.  subr.el defines the
        former as an alias for the latter.
        * data.c (Fnumber_to_string): Renamed from Fint_to_string.
        (wrong_type_argument): Adjust caller.

        appeared in X11R4; for earlier versions, just access the members
        of the Display directly.

        * xrdb.c (get_user_db): Since xrdb.c doesn't #include xterm.h,
        we can't test HAVE_X11R4 to see how we should get the resource

        If we're doing ordinary linking, define LIB_STANDARD appropriately.

        #define NSIG, if it's not already defined.
        #define HAVE_TERMIOS instead of HAVE_TCATTR.
        Provide our own definition of LIB_X11_LIB.

        that these can be called during GC; we have to ignore mark bits.
        * lisp.h (GC_NILP, GC_EQ): New macros to help with that.

        * print.c (float_to_string): Define buf to be an unsigned char, to

        * data.c (Fstring_to_number): Just skip tabs and spaces; don't use
        the <ctype.h> macros.  The <ctype.h> stuff apparently varies from
        locale to locale more than we'd like.  Don't include <ctype.h>.

        * alloc.c (make_pure_float): Assure that PUREBEG + pureptr is
        aligned, not pureptr itself.

        * emacs.c (fatal_error_signal): Unblock the signal before we try
        to deliver it to ourselves. #include "syssignal.h" to get the
        right definitions.

        * abbrev.c (Fexpand_abbrev): Only copy the text we're going to
        expand - from wordstart to wordend, not from wordstart to point -
        into the buffer.  There might be non-word text between wordend and
        point.

1993-02-23  Richard Stallman  (rms@geech.gnu.ai.mit.edu)

        * unexec.c (adjust_lnnoptrs): Handle symentry.n_type == 0x2400.

        the sigchld handler clear *input_available_clear_time.
        (wait_reading_process_input): Check for process activity after
        setting the timeout and calling set_waiting_for_input.
        (sigchld_handler): If the process which has exited is one we care
        about, clear *input_available_clear_time.

        * frame.c (Fselect_frame): Set Vlast_event_frame to Qnil after
        switching frames, to make sure we'll get a switch-frame event.

        on non-USG systems, which supposedly have a logb function.

        that have rint.

        * process.c (process_send_signal): Use TERMIOS functions in
        preference to BSD ioctls.  Some systems attempt to provide the BSD
        functions for backward compatibility, and get it wrong.

        * data.c (Fstring_to_number): Skip initial spaces, to make Emacs
        lisp parse consistently on different operating systems.
        #include <ctype.h> to help with this.

        * data.c (Fstring_to_int): Rename this to Fstring_to_number, since
        it parses floats as well as integers.  Fix docstring.
        (syms_of_data): Fix defsubr.
        (wrong_type_argument): Change use.
        (Fint_to_string): Doc fix.

        * window.c (Fscroll_other_window): Same.

        * keyboard.c (command_loop_1): Apply XINT to c before passing it
        to internal_self_insert and direct_output_for_insert.

        * keyboard.c (make_lispy_movement): Rename the variable `part'
        declared in the block handling scrollbar movement to `part_sym',
        to avoid potential conflicts with the argument named `part'.
        Apparently the semantics of expressions like this are unclear.

        * process.c (Fstart_process): Jimb's change of December 11
        had a misplaced paren.  This only became apparent because of

        * xterm.c (x_set_window_size): Call change_frame_size instead of
        just setting the `rows' and `cols' members of the frame, and
        leaving the window tree in complete disarray.

        * dispnew.c (remake_frame_glyphs): When re-allocating the frame's
        message buffer when echo_area_glyphs is pointing at it, relocate
        echo_area_glyphs too.  Same for previous_echo_glyphs.
        * window.h (previous_echo_glyphs): Add extern declaration for this.

        * frame.c (Fframe_parameters): Report the `minibuffer' parameter of
        minibufferless frames as nil, not `none'.
        (Qnone): Remove declaration and initialization for this.  It's not
        needed anymore.
        * xfns.c (Qnone): Add them here; we still accept "none" as a valid
        value for the `minibuffer' parameter.

        * xfns.c (x_frame_params): Remember that the parameters are called
        "auto-raise" and "auto-lower", not "autoraise" and "autolower".

        * xdisp.c (message): Set echo_frame to the frame whose message buf
        we want to use, not to the message buf itself.

        * fileio.c (Fdo_auto_save): If NO_MESSAGE is non-nil, don't tell
        users that buffers have shrunk a lot.  This is called when Emacs
        is crashing, so we don't want to run any code that isn't
        absolutely necessary.  Also, autosave buffers which don't have
        specially handled autosave file names first.

1993-02-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * editfns.c (Fcompare_buffer_substrings): Ignore case

        describe_vector): Pass the proper arguments to Flookup_key.

        coordinates for the menu position into root-window-relative
        coordinates.

        * lread.c (read1): Although digits followed by a '.' are an
        integer, a single . by itself (like, say, \.) should be a symbol.

1993-01-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * fns.c (internal_equal): Protect the clause for comparing numbers
        of different types with a "#ifdef LISP_FLOAT_TYPE".

        (Qfirst_change_hook): Added declaration.
        * insdel.c (signal_before_change): Change references to

        directly.

        x-selection-value has been renamed to x-selection.
        x-own-selection has been renamed to x-set-selection, and the order
        of its arguments has been reversed, for consistency with other
        lisp functions like put and aset.
        * xselect.c (Fx_own_selection): Rename to Fx_set_selection, 
        reverse the order of the args, and therefore make the type
        non-optional.  Doc fix.
        (Fx_selection_value): Rename to Fx_selection; make the type
        argument non-optional, for symmetry with Fx_set_selection.  Doc
        fix.
        (syms_of_xselect): Adjusted.

        * xselect.c (Fx_own_selection, Fx_selection_value): Remove "#if
        0"'ed code which made cut buffers look like a special selection
        type.

        * xfns.c (Vx_selection_value): Removed extern declaration for
        this; it's never used.

        * data.c (Fcompiled_function_p): Renamed to Fbyte_code_function_p.
        (syms_of_data): Adjusted.

        * data.c (Fnumberp, Fnumber_or_marker_p): Use the NUMBERP macro,
        instead of writing it out.

        * fns.c (internal_equal): If the operands are both numbers,
        compare them numerically, so that (equal 1.0 1) => t.

        instead of text_cursor_kind.
        (Vbar_cursor): Delete external declaration.

        (Qbar, Qbox, Qcursor_type): New symbols. 
        (syms_of_xfns): Init and staticpro them; remove DEFVAR for
        Vbar_cursor.
        (x_set_cursor_type): New setter.
        (x_frame_parms): Add it to the list.
        (Fx_create_frame): Get default values for the cursor type.

        * frame.c (Fmouse_position): Pass the appropriate arguments to
        *mouse_position_hook; the protocol was changed, but this caller
        wasn't fixed.

        * xterm.c (XTclear_frame): Call x_scrollbar_clear.
        (x_scrollbar_clear): New function.

        * xterm.c (XTflash): Totally rewritten.  Only defined if
        HAVE_TIMEVAL and HAVE_SELECT are defined, since we use select for
        our timing.
        (timeval_subtract): New function, to help XTflash.
        (x_invert_frame): Removed.  This didn't work anyway.
        (XTring_bell): Remove "#if 0" around call to XTflash, and remove
        calls to x_invert_frame.  If both HAVE_TIMEVAL and HAVE_SELECT
        aren't defined, then just do the ordinary beep.

        * window.c (Fscroll_other_window): Prefer windows on the selected
        frame, then look for windows on other visible frames.

        * keyboard.c (Fmouse_click_p): Removed; with the 'e' spec, this
        isn't necessary anymore.
        (syms_of_keyboard): Remove defsubr for it.
        * keyboard.h (Fmouse_click_p): Remove extern declaration for it.

        * xfns.c (gray_bits): Remove this declaration; the same data is in
        <X11/bitmaps/gray>.  #include that instead.
        [not HAVE_X11] (x_set_border_pixel): Use gray_width and
        gray_height, instead of assuming that the bitmap is 16x16.
        (x_make_gc): Instead of creating a pixmap and then calling
        XPutImage to make it into a grey stipple, just call
        XCreatePixmapFromBitmapData to do it all at once.

        * xterm.c (x_text_icon): Move the request for font information
        into the "not HAVE_X11" part of the function; the X11 code doesn't
        need this.

        * xterm.c (x_wm_set_icon_pixmap): Instead of setting the
        icon_pixmap to None, just remove IconPixmapHint from the flags of
        the XWMHints structure.

        * window.c (Fprevious_frame): Use prev_frame when we get to the
        end of the current frame, not next_frame.  Doc fix.
        * frame.c (prev_frame): Remove "#if 0" from this function.  It
        turns out we do need it, to make prev_frame work right.

        * frame.c (next_frame): Check that FRAME is a live frame.

        * frame.c (Fselect_frame): Remove "#ifdef MULTI_FRAME" clause
        around the code which calls Ffocus_frame; this code is already
        inside an "#ifdef MULTI_FRAME" clause.
        (next_frame, prev_frame, Fnext_frame): For the same reasons,
        remove the "#ifdef MULTI_FRAME" clause around these functions.

        unread-command-event has been replaced by unread-command-events.
        * commands.h (unread_command_event): Change extern declaration.
        * keyboard.c (unread_command_event): Change the definition.
        (syms_of_keyboard): Change DEFVAR, and adjust the docstring.
        (command_loop_1, read_char, Finput_pending, Fdiscard_input,
        quit_throw_to_read_char, init_keyboard): Change to use
        unread_command_events, with the new semantics.
        * lread.c (read_char): Same.
        * minibuf.c (temp_echo_area_glyphs): Same.
        * xterm.c (unread_command_event): Remove external declaration for
        this; it is only used by obsolete code.

        * Makefile.in: Some makes can't handle comments in the middle of
        commands; move them to before the whole rule.

1993-01-21  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * keyboard.c (make_lispy_event): When handling a mouse click event
        on a window, change x and y from screen coordinates to window
        coordinates even when the click isn't in the text area.

        * xterm.c (x_scrollbar_create): Remove code which asks for
        EastGravity for windows; Emacs can't correctly deal with them
        moving around unexpectedly.

        * xterm.c (XTread_socket): Minor reformatting.

        * xterm.c (x_set_window_size): Always mark the frame garbaged.

        * window.c (Vmouse_window): Variable removed; it can't be handled
        properly without race conditions, and the events give you all the
        information you need anyway.
        (syms_of_window): Remove DEFVAR.
        * callint.c (Fcall_interactively): Change the `@' spec to select
        the window of the first parameterized event in the key sequence
        which invoked the command, instead of using Vmouse_window, which
        isn't even updated anymore.  Adjust the documentation
        accordingly.

1993-01-20  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * xterm.c (x_scrollbar_create): Set the scrollbars to use
        EastGravity.

        * keyboard.c (make_lispy_event): Deal with button releases with no
        stored down-going position.  Make sure we always store a Qnil in
        the right button_down_location element after using it.

1993-01-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * frame.c (Fdelete_frame): Clear the frame's display after calling
        the window-system-dependent frame destruction routine.  We
        no longer need to pass the display as a separate argument to
        x_destroy_window.
        * xterm.c (x_destroy_window): Put the code which clears out f's
        display here, right after we free the storage it points to.  Put
        everything, including the code which clears x_focus_frame and
        x_highlight_frame, inside the BLOCK/UNBLOCK_INPUT pair.

        * dispnew.c (Fredraw_display): Undo change of Jan 12; redraw only
        frames whose garbaged flag is set.  The change to
        FRAME_SAMPLE_VISIBILITY on Jan 14 should address the problem better.

        keyboard.c (read_char_menu_prompt): Test HAVE_X_WINDOWS, not
        HAVE_X_WINDOW.

        The CPP symbol indicating whether or not we have mouse menu
        support under X Windows is HAVE_X_MENU, not not NO_X_MENU.
        * emacs.c (main): Test HAVE_X_MENU, instead of NO_X_MENU.
        * keyboard.c (read_char_menu_prompt): Same.
        * ymakefile: Same.

        * keyboard.c (read_char, read_char_menu_prompt): Use the
        EVENT_HAS_PARAMETERS macro from keyboard.h, instead of writing it
        out.

        * keyboard.c (read_char_menu_prompt): Doc fix.

        * keyboard.c (read_char_menu_prompt): Fix test for no menus;
        comparing name to Qnil doesn't work if we are called with no maps.

        * keymap.c (Fdefine_key): Call Fkey_description to make the string
        to use in the error message.

1993-01-18  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * window.c (Fdisplay_buffer): Doc fix.

1993-01-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xterm.c (x_window_to_scrollbar): Search frames'
        condemned_scrollbars list as well; input might arrive during
        redisplay.
        (x_scrollbar_report_motion): Don't forget to BLOCK_INPUT.
        (XTjudge_scrollbars): Clear the condemned scrollbar list before
        traversing it, so we don't try to process an event on a scrollbar
        we've killed.

1993-01-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (Frecent_keys): Doc fix.

1993-01-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * window.c (Fwindow_at): Doc fix.

1993-01-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * xterm.c (x_scrollbar_create): Include PointerMotionHintMask in
        the event mask for scrollbars.

        * dispnew.c (Fredraw_display): DEFUN was missing a closing paren.

        * term.c (set_vertical_scrollbar_hook, condemn_scrollbars_hook,
        redeem_scrollbar_hook, judge_scrollbars_hook): Removed dumbo
        "externs" from these.  They're supposed to be real definitions.

        * .gdbinit: Add "-geometry +0+0" to default args.
        (xscrollbar): New command.

        Make scrollbar structures into lisp objects, so that they can be
        GC'd; this allows windows and scrollbars can refer to each other
        without worrying about dangling pointers.
        * xterm.h (struct x_display): vertical_scrollbars and
        judge_timestamp members deleted.
        (struct scrollbar): Redesigned to be a template for a Lisp_Vector.
        (SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK,
        SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW,
        VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE,
        VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
        New macros, to help deal with the lispy structures, and deal with
        the graphics.
        * frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.
        (struct frame): New fields `scrollbars' and
        `condemned_scrollbars', for use by the scrollbar implementation.
        [MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS,
        FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field.
        * window.h (struct window): Doc fix for vertical_scrollbar field.
        * frame.c (make_frame): Initialize the `scrollbars' and
        `condemned_scrollbars' fields of the new frame.
        * alloc.c (mark_object): Mark the `scrollbars' and
        `condemned_scrollbars' slots of frames.
        * xterm.c (x_window_to_scrollbar): Scrollbars are chained on
        frames' scrollbar field, not their x.display->vertical_scrollbars
        field.
        (x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,
        x_scrollbar_remove, XTset_vertical_scrollbar,
        XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,
        x_scrollbar_expose, x_scrollbar_handle_click,
        x_scrollbar_handle_motion): Substantially rewritten to correct
        typos and brainos, and to accomodate the lispy structures.

        * xterm.c (x_scrollbar_background_expose): Function deleted; we
        don't want anything in the background there after all.
        (XTread_socket): Don't call x_scrollbar_background_expose.  We
        don't care.

        * frame.h (FRAME_SAMPLE_VISIBILITY): Make sure frame is marked as
        garbaged whenever it goes from invisible to visible.
        * dispextern.h (frame_garbaged): Move extern declaration from here...
        * frame.h (frame_garbaged): ... to here.  The FRAME_SAMPLE_VISIBILITY
        macro uses it now, and this seems to be just as modular.  Make a
        new page, just for this and message_buf_print.
        (struct frame): Doc fix for the `visible' field.
        * process.c: #include "frame.h" instead of "dispextern.h"; the
        only thing we care about from it is the frame_garbaged
        declaration.
        * ymakefile: Note dependency change.

        * xfns.c (Fx_create_frame): After mapping the frame, call
        SET_FRAME_GARBAGED, not just plain FRAME_GARBAGED.

        * window.c (window_internal_width): New function, which accounts
        for scrollbars if present.
        * lisp.h (window_internal_height, window_internal_width): Add
        extern declarations for these.
        * dispnew.c (direct_output_for_insert, direct_output_forward_char,
        buffer_posn_from_coords): Use window_internal_width instead of
        writing out its definition.
        * indent.c (compute_motion): Doc fix; mention scrollbars and
        window_internal_width.
        (pos_tab_offset, Fvertical_motion): Use window_internal_width
        instead of writing it out.
        * window.c (Fpos_visible_in_window_p, Fwindow_width, Fscroll_left,
        Fscroll_right): Same.
        * xdisp.c (redisplay, try_window, try_window_id,
        display_text_line): Same.

        * xdisp.c (display_string): Add new variable `f', to be W's
        frame.  Use it to set desired_glyphs, and to get the frame's width
        to decide whether or not to draw vertical bars.

        * xdisp.c (display_text_line): If we're using vertical scrollbars,
        don't draw the vertical bars separating side-by-side windows.
        (display_string): Same thing.  Draw spaces to fill in the part of
        the mode line that is under the scrollbar in partial-width
        windows.

        * xfns.c (Qvertical_scrollbars): New symbol.  Use it as the name
        of the parameter which decides whether or not the frame has
        scrollbars, instead of Qvertical_scrollbar.
        (Fx_create_frame): Adjusted accordingly.
        (syms_of_xfns): Initialize and staticpro Qvertical_scrollbars.
        (x_set_vertical_scrollbar): Renamed to x_set_vertical_scrollbars.
        (x_frame_parms): Adjusted accordingly.

        * xterm.h (CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT,
        PIXEL_TO_CHAR_WIDTH, PIXEL_TO_CHAR_HEIGHT): Rewritten, using:
        (CHAR_TO_PIXEL_ROW, CHAR_TO_PIXEL_COL, PIXEL_TO_CHAR_ROW,
        PIXEL_TO_CHAR_COL): New macros.
        * xfns.c [not HAVE_X11] (Fx_create_frame): Use the
        PIXEL_TO_CHAR_{HEIGHT,WIDTH} macros to figure the frame's
        character size, and the CHAR_TO_PIXEL* macros for vice versa.
        * xterm.c (XTwrite_glyphs, XTclear_end_of_line, stufflines,
        scraplines, dumprectangle, pixel_to_glyph_coords, x_draw_box,
        clear_cursor, x_display_bar_cursor, x_draw_single_glyph,
        x_set_mouse_position): Use the CHAR_TO_PIXEL_* macros.

        * xterm.c (x_wm_set_size_hint): The max_width and max_height
        members of the size_hints are expressed in pixels, not columns.

        * xterm.c (x_set_window_size): Remove ibw var; it's not used.
        Set FRAME_WIDTH (f) to cols instead of rows.  Duh.

        * xterm.c (pixel_to_glyph_coords): Properly set *bounds to the
        character cell bounding the position, even when the position is
        off the frame.

        * xfns.c (x_set_name): To request that the modelines be redrawn,
        execute the statement "update_mode_lines = 1;" instead of the
        silly statement "update_mode_lines;".

        * xfns.c (x_set_vertical_scrollbars): Don't try to set the
        X window's size if the frame's X window hasn't been created yet.

        * xfns.c (x_figure_window_size): Set the frame's
        vertical_scrollbar_extra field before trying to calculate its
        pixel dimensions.

        * xfns.c (x_window): When calling x_implicitly_set_name for the
        sake of drawing the name for the first time, remember to clear and
        set the frame's explicit_name member as well as its name member.
        (Fx_create_frame): Set the frame's explicit_name member if the
        user specified the name explicitly.

        * xdisp.c (display_text_line): Use the usable internal width of
        the window, as calculated above, as the limit on the length of the
        overlay arrow's image, rather than using the window's width field,
        less one.

        * xdisp.c (redisplay): Call condemn_scrollbars_hook and
        judge_scrollbars_hook whenever they are set, not just when the
        frame has vertical scrollbars.

        * termhooks.h (mouse_position_hook): Doc fix.
        (set_vertical_scrollbar_hook): This doesn't return anything any
        more, and doesn't take a struct scrollbar * argument any more.
        (condemn_scrollbars_hook, redeem_scrollbar_hook,
        judge_scrollbars_hook): Doc fixes.
        * term.c (mouse_position_hook): Doc fix.
        (set_vertical_scrollbar_hook): This doesn't return
        anything any more.  Doc fixes.
        * keyboard.c (kbd_buffer_get_event): Receive the scrollbar's
        window from *mouse_position_hook and pass it to
        make_lispy_movement, instead of working with a pointer to a struct
        scrollbar.
        (make_lispy_event): We don't need a window_from_scrollbar function
        anymore; we are given the window directly in *EVENT.
        Unify the code which generates
        text-area mouse clicks and scrollbar clicks; use the same code to
        distinguish clicks from drags on the scrollbar as in the text area.
        Distinguish clicks from drags by storing a copy of the lispy
        position list returned as part of the event.
        (button_down_location): Make this a lisp vector, rather than an
        array of random structures.
        (struct mouse_position): Remove this; it's been replaced by a lisp
        list.
        (make_lispy_movement): Accept the scrollbar's window as a
        parameter, rather than the scrollbar itself.
        If FRAME is zero, assume that the other arguments are garbage.
        (syms_of_keyboard): No need to staticpro each window of
        button_down_location now; just initialize and staticpro it.
        * window.c (window_from_scrollbar): Function deleted; no longer
        needed.
        * xdisp.c (redisplay_window): Just pass the window to
        set_vertical_scrollbar hook; don't pass the scrollbar object too.
        * xterm.c (XTmouse_position): Don't return a pointer to the
        scrollbar for scrollbar motion; instead, return the scrollbar's
        window.

        * xterm.c (XTmouse_position): Entirely rewritten, using
        XTranslateCoordinates.  Call x_scrollbar_report_motion to handle
        scrollbar movement events.
        (x_scrollbar_report_motion): New function, to help out
        XTmouse_position.

        * keyboard.c (apply_modifiers): Don't assume that the Qevent_kind
        property of BASE is set when we first create the new modified
        symbol.  Check that the Qevent_kind property is properly set each
        time we return any symbol.

        * termhooks.h (struct input_event): Replace the frame member with
        a Lisp_Object member by the name of frame_or_window.  Doc fixes.
        Remove the scrollbar member; instead, use frame_or_window to hold the
        window whose scrollbar was clicked.
        * keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event,
        make_lispy_event): Adjust references to frame member of struct
        input_event to use frame_or_window now.
        * xterm.c (construct_mouse_click, XTread_socket): Same.

        * xterm.c (last_mouse_bar, last_mouse_bar_frame, last_mouse_part,
        last_mouse_scroll_range_start, last_mouse_scroll_range_end):
        Replaced with...
        (last_mouse_scrollbar): New variable.
        (note_mouse_movement): Clear last_mouse_scrollbar when we have
        receieved a new motion.
        (syms_of_xterm): Staticpro last_mouse_scrollbar.

        * xterm.c (note_mouse_position): Renamed to note_mouse_movement,
        because that's what it really does.
        (x_scrollbar_handle_motion): Renamed to x_scrollbar_note_movement,
        for consistency.
        (XTread_socket): Adjusted.

        * xterm.c (XTset_scrollbar): Renamed to XTset_vertical_scrollbar.
        (x_term_init): Adjusted.

        * keyboard.c (kbd_buffer_frames): Renamed to
        kbd_buffer_frame_or_window, and made to exist even when
        MULTI_FRAME isn't defined; single-frame systems might have
        scrollbars.  Use it to GCPRO the frame_or_window field in the
        event queue.
        (kbd_buffer_store_event, kbd_buffer_get_event,
        stuff_buffered_input): Set and clear the
        appropriate element of kbd_buffer_frame_or_window, whether or not
        MULTI_FRAME is #defined.
        (read_avail_input): When reading characters directly from stdin,
        set the frame_or_window field of the event appropriately,
        depending on whether or not MULTI_FRAME is #defined.
        (Fdiscard_input, init_keyboard): Zap kbd_buffer_frame_or_window,
        not kbd_buffer_frames.
        (syms_of_keyboard): Initialize and staticpro
        kbd_buffer_frame_or_window, whether or not MULTI_FRAME is
        #defined.

        * keyboard.c (head_table): Make Qscrollbar_movement have a
        Qevent_kind property of Qmouse_movement, not Qscrollbar_movement.

        * keyboard.c (read_key_sequence): If we decide to throw away a
        mouse event which has prefix symbols (`mode-line',
        `vertical-scrollbar', etcetera), remember that we may have to
        unwind two characters, not just one.

        * keyboard.c (read_key_sequence): Doc fixes.

        * keyboard.c (kbd_buffer_store_event): Fix reversed sense of test
        for focus redirection.

        * keyboard.c (read_char): Don't echo mouse movements.

        * emacs.c (shut_down_emacs): New function.
        (fatal_error_signal, Fkill_emacs): Call it, instead of writing it out.
        * xterm.c (x_connection_closed): Call shut_down_emacs instead of
        Fkill_emacs; the latter will try to perform operations on the X
        server and die a horrible death.
        * lisp.h (shut_down_emacs): Add extern declaration for it.

        * xterm.c (x_error_quitter): Move the abort call to after we print
        the error message.  No harm in that.

        * xdisp.c (echo_area_display): Move the assignment of f and the
        check for visibility out of the "#ifdef MULTI_FRAME" clause; they
        should work under any circumstances.

        * xdisp.c (redisplay_window): If we're not going to redisplay this
        window because it's a minibuffer whose contents have already been
        updated, go ahead and jump to the scrollbar refreshing code
        anyway; they still need to be updated.  Initialize opoint, so it's
        known to be valid when we jump.  Calculate the scrollbar settings
        properly for minibuffers, no matter what they are displaying at
        the time.

        * xdisp.c (redisplay_windows): Don't restore the current buffer
        and its point before refreshing the scrollbars; we need the buffer
        accurate.

1993-01-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        (x_default_parameter): Add XCLASS argument, to give the class of
        XPROP.  Pass it along to x_get_arg.
        (Fx_create_frame): Pass new args to x_get_arg and
        x_default_parameter.

        * xfns.c (Fx_create_frame): Use the same resource names and
        classes as xterm and Emacs 18.

1993-01-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfns.c (Fx_get_resource): Use EMACS_CLASS to make class_key
        even if SUBCLASS is specified.  I don't know whether that is
        right, but that's what the doc says.
        Cosmetic changes in arg names and doc string.

1992-12-29  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * ralloc.c: [! emacs] [HAVE_CONFIG_H]: #include "config.h"

        functions instead for events which occur in scrollbar windows.
        (XTupdate_end): Remove call to adjust_scrollbars; the main
        redisplay code takes care of that now.
        (enum window_type): Deleted.
        * ymakefile: Note that xfns.o no longer depends on xscrollbar.h.

        * xterm.c (x_set_mouse_position): Clip mouse position to be within
        frame.

        * xterm.c: Adjust the first line of each page to have a reasonable
        description.  This makes pages-directory more useful.

        * xterm.c (x_do_pending_expose): Declare this routine only if
        HAVE_X11 is not #defined; X11 doesn't need it.
        (XTread_socket): Protect call to x_do_pending_expose with `#ifdef
        HAVE_X11'. 

        * xfns.c (syms_of_xfns): Delete defvars for x_mouse_x and

1992-12-20  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        Properly handle focus shift events, so the cursor is filled and
        hollow at the appropriate times, even in titleless windows.
        * xterm.c (x_focus_event_frame): New variable.
        (XTread_socket): When we receive a FocusIn event that's not
        NotifyPointer, record the frame in x_focus_event_frame.  When we
        receive a FocusOut event that's not NotifyPointer, clear it.  When
        we get a LeaveNotify event, don't take it seriously if we still
        have focus.

        * xterm.c (XTread_socket): Remove special code in EnterNotify case
        to handle scrollbars and fake mouse motion events.

        * frame.h (focus_frame): Doc fix.
        [not MULTI_FRAME] (FRAME_FOCUS_FRAME): Make this Qnil, which
        indicates no focus redirection, instead of zero, which is
        selected_frame.
        * frame.c (make_frame): Initialize f->focus_frame to Qnil, rather
        than making it point to frame itself.
        (Fselect_frame): If changing the selected frame from FOO to BAR,
        make all redirections to FOO shift to BAR as well.  Doc fix.
        (Fredirect_frame_focus): Doc fix.  Accept nil as a valid
        redirection, not just as a default for FRAME.
        (Fframe_focus): Doc fix.
        * keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event): Deal
        with focus redirections being nil.
        * xterm.c (XTframe_rehighlight): Doc fix.  Deal with focus
        redirections being nil.

        * window.c (Fset_window_configuration): Don't restore the frame's
        focus redirection if the target frame is now dead.

        * ymakefile (ralloc.o): This no longer depends on xterm.h.

        * ymakefile (all, xemacs): We build an executable called `emacs' now,
        not `xemacs'.
        * Makefile.in (distclean, xemacs, doxemacs): Same.

        * xterm.h (PIXEL_WIDTH, PIXEL_HEIGHT): Change name of parameter
        from `s' to `f'; it's a frame pointer.

        sure to store its frame in kbd_buffer_frames.
        (kbd_buffer_get_event): When we remove an event from kbd_buffer,
        make sure to set the corresponding element of kbd_buffer_frames to
        Qnil, to allow the frame to get GC'd.
        (Fdiscard_input, init_keyboard): Clear all elements of
        kbd_buffer_frames to nil.
        (syms_of_keyboard): Create and staticpro kbd_buffer_frames.

1992-12-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * scroll.c (do_scrolling): When bcopying the max_ascent field from
        current_frame to temp_frame, remember that max_ascent is an array
        of shorts, not ints.

        It's a pain to remember that you can't assign to FRAME->visible.
        Let's change all references to the `visible' member of struct
        frame to use the accessor macros, and then write a setter for the
        `visible' field that does the right thing.
        * frame.h (FRAME_VISIBLE_P): Make this not an l-value.
        (FRAME_SET_VISIBLE): New macro.
        * frame.c (make_terminal_frame, Fdelete_frame): Use FRAME_SET_VISIBLE.

        (Fx_create_frame): Use FRAME_SET_VISIBILITY.
        * xterm.c (clear_cursor, x_display_bar_cursor,
        x_display_box_cursor): Use FRAME_SET_VISIBILITY.

        * ymakefile (CFLAGS): #define HAVE_CONFIG_H too.

        * Makefile.in (distclean): Don't delete machine.h or system.h;
        they don't exist anymore.

        * Makefile.in (distclean): Don't delete autosave or backup files.
        (extraclean): New target; like distclean, but delete autosave

        * search.c (Fskip_chars_forward, Fskip_chars_backward): Return the
        distance traveled.
        (skip_chars): Return the distance traveled, as a Lisp_Object.

        * macros.c (Fend_kbd_macro): Don't use XFASTINT to check if arg is
        negative; XFASTINT only works on values known to be positive.
        (Fexecute_kbd_macro): Check QUIT in the repetition loop.  If the
        macro is null, no characters are actually being read, so this
        matters.

        * Makefile.in (srcdir): New variable, not fully implemented.
        (xmakefile): Turn -g and -O in CFLAGS into C_DEBUG_SWITCH and
        C_OPTIMIZE_SWITCH in C_SWITCH_SITE's definition.  Delete junk.cpp
        when done.
        * ymakefile (archlib): Variable definition deleted.  Run programs
        from ../lib-src directly, or use ${archlibdir}.
        (${etc}DOC): Run make-docfile from ${libsrc}, not ${archlib}.
        (${archlib}make-docfile, ${archlib}emacstool): Use ${libsrc}, not
        ${archlib}.

        * ymakefile (lisp): Don't include version.el in this list.

        name.
        * fileio.c (Funhandled_file_name_directory): New function.
        (Qunhandled_file_name_directory): New file-name-handler operation.

        initialize and staticpro Qunhandled_file_name_directory.
        * callproc.c (Fcall_process): Call Funhandled_file_name_directory
        on the buffer's default directory.  Do it earlier in the function
        so there's less to GCPRO.
        * process.c (create_process): Don't check the validity of the 
        buffer's default directory here...
        (Fstart_process): Instead, do it here; if we call
        Funhandled_file_name_directory here, there's less GCPROing to do.

        * callproc.c (Fcall_process_region): Return the value returned by
        Fcall_process.

        * fileio.c (find_file_handler): Rename this to
        Ffind_file_name_handler, and make it visible to lisp.  Add a QUIT
        to the loop which scans file-name-handler-alist.  All uses
        changed.
        (syms_of_fileio): Mention this new function in the docstring for
        Vfile_name_handler_alist.  defsubr Sfind_file_name_handler.
        * lisp.h (Ffind_file_name_handler): Added extern declaration.
        * dired.c: All uses of find_file_handler changed here too.

        * fileio.c (syms_of_fileio): Add staticpros for Qexpand_file_name,
        Qdirectory_file_name, Qfile_name_directory,
        Qfile_name_nondirectory, Qfile_name_as_directory.

1992-12-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * window.c (Fset_window_configuration): If we're restoring the
        configuration of a dead frame, don't bother rebuilding its window
        tree, restoring its focus redirection, or temporarily resizing it
        to fit the saved window configuration.  If the frame which was
        selected when the configuration was captured is now dead, don't
        try to select it.

        * frame.c (Fdelete_frame): Delete all the windows in the frame's
        window tree, using delete_all_subwindows.
        * window.c (delete_all_subwindows): Don't make this static
        anymore.

1992-12-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        Make sure that frames' visible flag only changes at acceptable
        times.  See FRAME_SAMPLE_VISIBILITY's comments for details.
        * frame.h (struct frame): New fields called async_visible and
        async_iconified.
        (FRAME_SAMPLE_VISIBILITY): New macro, with MULTI_FRAME and
        non-MULTI_FRAME definitions.
        * xdisp.c (redisplay): Call FRAME_SAMPLE_VISIBILITY to set the
        visible and iconified flags appropriately for each frame.
        (message1): Call FRAME_SAMPLE_VISIBILITY to set the visible and
        iconified flags for the minibuffer frame.
        * frame.c (make_frame): Initialize async_visible and
        async_iconified properly.
        * xfns.c (Fx_create_frame): Initialize f->async_visible too.
        * xterm.c (XTread_socket): When we get MapNotify, UnmapNotify,
        Expose, ExposeWindow, or UnmapWindow, set f->async_visible, not
        f->visible.
        (x_do_pending_expose, x_raise_frame, x_lower_frame,
        x_make_frame_invisible, x_make_frame_visible, x_iconify_frame):
        Test and set f->async_visible and f->async_iconified, not
        f->visible or f->async_iconified.

        * keyboard.c (kbd_store_ptr): Declare this to be volatile, if
        __STDC__ is #defined.
        (Fdiscard_input): Use cast to keep GCC from complaining about the
        assignment of kbd_store_ptr to kbd_fetch_ptr.

        * xdisp.c (redisplay): Use FOR_EACH_FRAME to apply
        redisplay_windows to the root window of each frame.  This makes a
        #ifdef MULTI_FRAME unneeded, but it also means we recompute
        buffer_shared from scratch even on non-MULTI_FRAME configurations.
        Don't skip elements of Vframe_list that aren't frames; go ahead
        and crash here.

        * xdisp.c (redisplay): Remove #ifdef MULTI_FRAME around the code
        which updates separate minibuffer frames specially; there's
        nothing there that won't work on a single-frame configuration.

        * dispextern.h (struct frame_glyphs): Doc fix.

1992-12-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * dispnew.c: Remove dyked-out copy of safe_bcopy.

        * environ.c: File removed; Changes on 1/13/1992 made it
        unnecessary.

1992-12-01  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * process.c (wait_reading_process_input): Doc fix.

1992-11-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * next.h: Copy changes from 18.59:
        (NeXT): Defined.
        (BIG_ENDIAN): Define only if __BIG_ENDIAN__.
        (m68000, COMPILER_REGISTER_BUG): Defs deleted.
        (SIGN_EXTEND_CHAR, LIB_X11_LIB, NO_T_CHARS_DEFINES, UNEXEC): Defined.
        (LIBS_DEBUG, LIB_GCC, C_SWITCH_MACHINE, ORDINARY_LINK): Defined.
        (TEXT_START, TEXT_END, DATA_END, LD_SWITCH_MACHINE): Defined.
        (KERNEL_FILE): #undef it.
        (environ): Define as _environ.

1992-11-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * doc.c (store_function_docstring): New function, made from part
        of Fsnarf_documentation, which handles docstrings for macros
        properly.
        (Fsnarf_documentation): Call store_function_docstring.

        * data.c (indirect_function): Delete unused argument ERROR.

1992-11-23  Jim Blandy  (jimb@apple-gunkies.gnu.ai.mit.edu)

        * Makefile.in (clean): Remove prefix-args.

1992-11-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/sol2.h (LD_SWITCH_SYSTEM): Make alternate version for GCC.

1992-11-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * m/sparc.h: Don't include <sys/param.h> here; that screws up the
        xmakefile.  Instead, include it in getloadavg.c, which is the only
        place that uses LOAD_AVE_CVT, which is the only reason
        <sys/param.h> was here in the first place.

1992-11-15  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * dispnew.c [not MULTI_FRAME] (Fredraw_display): Pass the correct
        number of arguments to mark_window_display_accurate.

        * undo.c (Fprimitive_undo): Remove whitespace in front of #ifdef
        and #endif.

        * systty.h: Doc fix.
        
        * systty.h, process.c, buffer.h, callproc.c, sysdep.c, dired.c:
        Added VMS changes from Roland Roberts.
        * vmspaths.h: New version from Roland Roberts.

        * xdisp.c (display_string): Use w's buffer's value of
        tab-width to display the string, instead of the current buffer's,
        which could be anything.

        * s/sol2.h (LD_SWITCH_SYSTEM): Add -R option.

        * process.c (read_process_output): Save, widen, insert the process
        output, and then restore the restriction if inserting text outside
        the visible region.

1992-11-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * buffer.c (Ferase_buffer): Doc fix.

        * dispnew.c (safe_bcopy): Use the right terminating condition in
        the loop which uses multiple bcopy calls to transfer a block to an
        overlapping higher block.

1992-11-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * process.c (Fstart_process): Establish an unwind-protect to
        remove PROC from the process list if an error occurs while
        starting it.
        (start_process_unwind): New function to help with that.
        (create_process): There's no need to explicitly call
        remove_process if the fork fails; the record_unwind_protect in
        Fstart_process will take care of it.

        * commands.h (unread_command_event): Doc fix.

        Don't ever throw away switch-frame events.
        * lread.c: #include "keyboard.h".
        (Fread_char, Fread_char_exclusive): Don't signal an
        error for or throw away switch-frame events; instead, put them off
        until after we've found a character we can respond to.
        * commands.h (unread_switch_frame): Declare this extern.
        * keyboard.c (unread_switch_frame): Don't declare this static.
        * ymakefile (lread.o): Note that this depends on keyboard.h.

        * keyboard.c (Vlast_event_frame): Doc fix.

        * process.c (wait_reading_process_input): Test the C preprocessor
        symbol "ultrix", not "__ultrix__" to see if we should ignore
        ENOMEM errors from select.

        * fileio.c (Fexpand_file_name): Don't fiddle with "/." if it's the
        entire string.

        * buffer.c (Fbury_buffer): Make this behave as in 18.59, although
        that behavior is very odd - only remove the buffer from the
        selected window if BUFFER was nil or omitted.

        * keyboard.c (read_char): Write composite events to the dribble
        file properly.

        * keyboard.c (init_keyboard): Initialize Vlast_event_frame to
        Qnil, rather than the selected frame.

        * mem-limits.h [DATA_SEG_BITS] (EXCEEDS_LISP_PTR): Remember to
        remove DATA_SEG_BITS from the pointer before testing if the
        pointer fits in VALBITS.

        * Makefile.in (doxemacs, dotemacs): Explicitly pass along the CC
        variable in these rules, just as in the `doall' rule.

        * ralloc.c (relocate_some_blocs): Handle BLOC == NIL_BLOC.
        (free_bloc): This can now be simplified.

        * ralloc.c (r_alloc_sbrk): When we allocate new space for the
        malloc heap, zero it out even if we don't have any blocs in the
        free list.

1992-11-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * process.c (process_send_signal): On systems which have both
        the TIOCGETC and TCGETA ioctls, just use the former.

        * xselect.c (Fx_get_cut_buffer): Correct check for buf_num in
        range.

        * xselect.c (Fx_get_cut_buffer, Fx_set_cut_buffer): Fix error
        message format; use NUM_CUT_BUFFERS instead of literal 7.

        * keyboard.c (lispy_modifier_list): Added sanity check before
        indexing into modifier_symbols.

        * keyboard.c (add_command_key): When copying the contents of the
        old this_command_keys to new_keys, remember to multiply size by
        sizeof (Lisp_Object) to get the amount we really need to copy.

        Rename unread_command_char to unread_command_event; it has
        subtly different semantics now, and we should use
        `make-obsolete-variable' to warn people.
        * command.h (unread_command_char): Change name in extern declaration.
        * keyboard.c (unread_command_char): Rename.
        (command_loop_1, read_char, Finput_pending, Fdiscard_input,
        quit_throw_to_read_char, init_keyboard, syms_of_keyboard): Change
        references.
        * lread.c (Fread_char): Change reference.
        * minibuf.c (temp_echo_area_glyphs): Change reference to
        unread_command_char to unread_command_event.
        * xfns.c (unread_command_char): Change name in extern declaration
        to unread_command_event.

1992-11-11  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * m/pmax.h: Don't define SYSTEM_MALLOC; this was only necessary
        for Ultrix version 4.1, and the current version is 4.3.

        * s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
        * process.c (process_send_signal): Put all the code for sending
        signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS.  Decide
        whether to use the Berkeley-style or SYSV-style ioctls by seeing
        which ioctl commands are #defined.

        * minibuf.c (read_minibuf): If get_minibuffer gives the
        new minibuffer a nil default directory, find another buffer with a
        better default directory and use that one's instead.

1992-11-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * process.c (process_send_signal): Doc fix.

        * keyboard.c (read_key_sequence): Don't use
        save_excursion_{save,restore} to protect the caller against buffer
        switches; use Fset_buffer and Fcurrent_buffer; redisplay might
        change point, and we don't want to undo that.

        * keyboard.c (kbd_buffer_get_event): When checking a mouse
        movement for a frame switch, don't assume Vlast_event_frame
        contains a Lisp_Frame object.

1992-11-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/dgux.h (SYSTEM_TYPE): Use berkeley-unix.

1992-11-04  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * alloc.c: #include "frame.h" unconditionally.  frame.h does the
        right thing when MULTI_FRAME isn't defined.

        * Makefile.in: Rearrange dependencies to make sure that xmakefile
        is built before we try to use it, even using a parallel make.

        Changes for SYSV from Eric Raymond:
        * process.c [SYSV]: Don't include <termios.h>, <termio.h>, or
        <fcntl.h>.
        (process_send_signal): Don't try to send SIGTSTP
        unless SIGTSTP is defined.
        * sysdep.c (init_baud_rate) [HAVE_TERMIO, not HAVE_TCATTR]: Use
        TCGETA, not TIOCGETP.
        * systime.h [USG] (EMACS_GET_TZ_OFFSET): Assign to *(offset), not
        (offset).  Don't forget the while corresponding to the do.
        Include USG in the list of systems that have a tzname array.

        * keyboard.c (read_key_sequence): Removed the
        replay_sequence_new_buffer label; replay_sequence should be here
        instead.

        Arrange to get compile-time errors for uses of Lisp_Frame in a
        non-MULTI_FRAME configuration.
        * lisp.h [not MULTI_FRAME]: Don't declare the Lisp_Frame tag.
        * minibuf.c (read_minibuf): Protect call to Fredirect_frame_focus
        with a #ifdef MULTI_FRAME.
        * window.c (Fset_window_configuration): Protect call to
        Fselect_frame with a #ifdef MULTI_FRAME.
        [not MULTI_FRAME] (Fcurrent_window_configuration): Don't bother
        setting the window configuration's selected_frame member.
        * keyboard.c (Vlast_event_frame): Arrange for this to exist iff
        MULTI_FRAME is defined.
        [not MULTI_FRAME] (syms_of_keyboard): Don't DEFVAR Vlast_event_frame.
        [not MULTI_FRAME] (read_char): Don't try to set Vlast_event_frame.
        [not MULTI_FRAME] (kbd_buffer_store_event): Don't try to set
        Vlast_event_frame for quit characters.
        [not MULTI_FRAME] (kbd_buffer_get_event): Don't try to generate
        switch-frame events.

        * buffer.c (init_buffer): If PWD is accurate, use it instead of
        calling getwd.
        #include <sys/types.h> and <sys/stat.h>, for the call to stat.

        Indicate whether an autoload form stands for a keymap or not.
        * eval.c (Fautoload): Renamed fifth argument TYPE.  Document the
        fact that (eq TYPE 'keymap) means FUNCTION will become a keymap
        when loaded.
        (Fmacroexpand): Instead of assuming that every autoload
        form with a fifth element is a macro, actually check the fifth
        element against t and `macro', which are the only values which
        denote macroness.
        * keymap.c (get_keymap_1): Don't try to autoload OBJECT's function
        unless the autoload form indicates that it's a keymap.

1992-11-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * .gdbinit (mips): New command.

1992-10-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c (Fmake_directory_internal): Renamed from Fmake_directory.
        Pass nil as third arg to handler.
        Lisp function `make-directory' is now in files.el.

1992-10-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        Clean up errors due to treating Lisp_Objects like integers.
        * abbrev.c (Funexpand_abbrev): Just assign the last abbrev's value
        to val; don't use XSET.  Make sure that the value of the
        abbrev-symbol is a string.
        * alloc.c (Frope_elt): Declare arguments to be Lisp_Objects.
        * buffer.c (reset_buffer): Don't assign to b->save_length as if it
        were an int; use XFASTINT.
        * buffer.h (Fbuffer_name, Fget_file_buffer): Added external
        declarations.
        * bytecode.c (Fbyte_code): Use EQ to compare string_saved with
        bytestr.
        * casefiddle.c (operate_on_word): Declare end to be an int, not a
        Lisp_Object.
        * casetab.c (set_case_table): Declare this to be static, and
        return a Lisp_Object. Add static declaration for this
        before Fset_case_table and Fset_standard_case_table.
        (Fset_case_table, Fset_standard_case_table): Return the return
        value of set_case_table, instead of returning garbage.
        * commands.h (unread_command_char): Declare this to be a
        Lisp_Object, not an int.
        * data.c (Fset): See if current_alist_element points to itself
        using EQ, not ==.
        (float_arith_driver): Declare this extern above arith_driver.
        * dired.c (find_file_handler): Declare this extern.
        (Ffile_attributes): Use NILP, not == Qnil.

        Lisp_Object.
        * fns.c: #include keyboard.h.
        (Fdelete): Check if Fequal returns Qnil, not zero.
        * frame.c: #include buffer.h.
        * keyboard.c: #include dispextern.h.
        (recursive_edit_unwind, command_loop, Fthis_command_keys): Declare
        these to return Lisp_Objects at the very top of the file, to avoid
        having them implicitly declared as ints.
        (echo_char): Use EQ to compare C to help_char.
        (read_char): Remember to apply XFASTINT to the return value of
        Flength before using it.  Apply XINT to c when clearing its high
        bits and meta bits, and when writing it to the dribble file.
        (read_char_menu_prompt): Use EQ to compare obj with
        menu_prompt_more_char and its control-character analog.
        (read_key_sequence): Declare PROMPT to be char *, not a
        Lisp_Object.  Use the appropriate accessors on keybuf when looking
        for ASCII function key sequences.
        * keyboard.h (get_keymap_1, Fkeymapp, reorder_modifiers,
        Fmouse_click_p, read_char): Add external declarations for these.
        * keymap.c (Fdefine_key, Flookup_key, describe_map): Don't assume
        that Flength returns an integer.
        * lisp.h (Fdefault_boundp, make_float, Ffloat, Fnth, Fcopy_alist,
        Fmake_byte_code, Fverify_visited_file_modtime, Ffile_exists_p,
        Fdirectory_file_name, Ffile_name_directory,
        expand_and_dir_to_file, Ffile_accessible_directory_p, Fbyte_code,
        Fundo_boundary, truncate_undo_list): Add extern declarations for
        these.
        * lread.c (read_char): Add an extern declaration for this,
        indicating that it returns a Lisp_Object.
        * minibuf.c (read_minibuf): Use EQ to compare, not ==.
        (temp_echo_area_glyphs): Use XFASTINT to assign to
        unread_command_char.
        * print.c (print): Cast the frame's address to an integer before
        passing it to sprintf to form the frame's printed form.
        * process.c: (status_convert): Declare this to return a
        Lisp_Object at the top of the file.
        (decode_status): Don't untag XCONS (tem)->cdr before storing it in
        tem; tem is a Lisp_Object, too.
        (process_send_signal): Declare this to be static void.  Don't
        return Qnil; nobody cares.
        (sigchld_handler): Use XFASTINT to manipulate p->infd.
        * search.c (Fstore_match_data): Don't assume Flength returns a
        C integer.
        * undo.c (record_insert): Use accessors on BEG and LENGTH.
        (truncate_undo_list): Use NILP, not == Qnil.
        * window.c (Fwindow_width, Fset_window_hscroll): Use accessors on
        w->width, w->left, w->hscroll, and arguments.
        (replace_window): Use EQ, not ==.
        (Fdelete_window): p->top and p->left are not C integers.
        (Fnext_window, Fprevious_window): Use EQ, not ==.
        * window.h (make_window, window_from_coordinates,
        Fwindow_dedicated_p): Add extern declarations for these.
        * xdisp.c (redisplay): Use ! EQ to compare the old and new arrow
        positions, not !=.
        (mark_window_display_accurate): Barf if WINDOW isn't a window.
        (display_string): Test buffer_defaults.ctl_arrow using NILP,
        instead of comparing it with zero.
        * xfns.c (x_decode_color, Fx_color_display_p): x_screen_planes is
        an int, not a Lisp_Object.
        (x_set_mouse_color): Give separate error messages for the
        different cursors we try to set.
        (Fx_geometry): Declare STRING to be a Lisp_Object.
        (Fx_create_frame): No need to use XSET to assign NAME to f->name;
        they're both Lisp_Objects.
        (adjust_scrollbars): Use XINT to access w->hscroll.
        (Fx_open_connection): x_screen_count, x_release, x_screen_height,
        x_screen_height_mm, x_screen_width, x_screen_width_mm,
        x_save_under, and x_screen_planes are integers, not Lisp_Objects.
        (syms_of_xfns): x_mouse_x, x_mouse_y, and mouse_buffer_offset are
        integers, not Lisp_Objects.
        * xselect.c (own_selection): selection_type is an X Atom value,
        not a Lisp_Object.
        (x_selection_arrival): Declare this static, and add a forward
        declaration at the top of the page.
        * xterm.c (x_convert_modifiers): Declare this to return an
        unsigned int, not a Lisp_Object.  Remember that the quiescent
        value for part is Qnil, not zero, that x_mouse_x and x_mouse_y
        are ints, not Lisp_Objects, and that RESULT->x and RESULT->y are
        Lisp_Objects, not ints.
        (XTread_socket): Declare this to return int, not Lisp_Object.
        When calling construct_mouse_click on a non-scrollbar click, pass
        PART as Qnil, not zero.
        (x_calc_absolute_position): Remember that x_screen_width and
        x_screen_height are ints, not Lisp_Objects.
        * xterm.h (x_screen_count, x_release, x_screen_height,
        x_screen_height_mm, x_screen_width, x_screen_width_mm,
        x_save_under, x_screen_planes): Declare this as ints, to match
        their definitions in xterm.c.
        * ymakefile: Note the new dependencies caused by the new
        #inclusions above.

        * xdisp.c (last_arrow_position, last_arrow_string): Make these
        static.

        * process.c (pty_process): Variable deleted; it's no longer used.
        (syms_of_process): Don't initialize it.

        * buffer.h (struct buffer_local_types): This declaration needed an
        extern qualifier.

        * floatfns.c (Fexpt): Don't return the value of the XSET function
        call; that's not guaranteed to be the value assigned.

        * dired.c (Ffile_attributes): Doc fix.

        * lisp.h (DEFVARLISP, DEFVARBOOL, DEFVARINT, DEFVARPERBUFFER):
        Removed these definitions; we should be using the versions whose
        names use underscores.

        * keyboard.c (echobuf): Make this 300 characters, not 100.  This
        isn't a real fix, but it's quick.

1992-10-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * callint.c (preserved_fns): New var.
        (Fcall_interactively): Preserve all fns listed in preserved_fns.
        (syms_of_callint): Set preserved_fns and staticpro it.

        * xdisp.c (message): Re-write this in terms of message1.
        (message1): Move code to clear out echo_area_glyphs and
        previous_echo_glyphs from message to here.

        * keyboard.c (read_char): When returning an unread switch-frame
        event, jump to reread_first to return it, rather than reread; this
        makes sure the event gets echoed (if appropriate) and goes into
        this_command_keys.

        * keyboard.c (read_key_sequence): If the key sequence starts with
        a mouse click, read the key sequence using the keymaps of the
        buffer clicked on, not the current buffer.

        * keyboard.c (unread_switch_frame): Make this static, to indicate
        that nobody outside of this file uses it.

        * keymap.c: Deal with autoloaded keymaps properly.
        (get_keymap_1): Renamed to inner_get_keymap; made
        static.  New argument AUTOLOAD says to pursue autoloads if
        non-zero.
        (Fkeymapp, get_keymap, get_keyelt, Flookup_key): Ask get_keymap_1
        not to perform autoloads.
        (Fdefine_key): Ask get_keymap_1 to perform autoloads.  Since
        autoloading may GC, remember that we have to GCPRO our local
        variables now.
        (Fminor_mode_key_binding): Call get_keymap instead of calling
        get_keymap_1 with equivalent arguments.
        * keyboard.c (follow_key): Ask get_keymap_1 to perform autoloads.
        (read_key_sequence): When pursuing potential bindings in the
        function key map, ask get_keymap_1 to perform autoloading.  This
        is hardly important, but it's consistent.
        * doc.c (Fsubstitute_command_keys): Ask get_keymap_1 to
        perform autoloads.  Autoloading might GC; we need to GCPRO our
        local variables now.
        (Fdocumentation, Fdocumentation_property): Autoloading in
        Fsubstitute_command_keys might GC; we need to GCPRO our
        local variables now.

        #include "syssignal.h".
        (call_process_kill): New function.
        (call_process_cleanup): Send SIGINT to the subprocess, and then
        arrange to call call_process_kill if the user quits while we wait
        for it to terminate.
        (Fcall_process, Fcall_process_region): Doc fix.

        (r_alloc_sbrk): Provide hysteresis in relocating the blocs.

1992-10-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * eval.c (grow_specpdl): Increase max_specpdl_size before Fsignal.

1992-10-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xfns.c (x_set_face): Dyked out this function; it has no callers,
        and refers to an obsolete version of struct face.

        * xterm.c (compose_status): New variable.
        (XTread_socket): Pass it by reference to XLookupString.

1992-10-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/esix5r4.h (BROKEN_FIONREAD): Defined.

1992-10-16  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        previous_echo_glyphs, so that the minibuffer shows through.
*       * editfns.c (Fmessage): With no arguments, clear any active
        message; let the minibuffer contents show through.
        * minibuf.c (temp_echo_area_glyphs): Don't clear echo_area_glyphs
        and previous_echo_glyphs; let message do that work.

        * keyboard.c (this_command_keys): Make this a vector, instead of
        an array of Lisp_Objects.
        (this_command_keys_size): Deleted.
        (echo, add_command_key, Fthis_command_keys): Adjusted
        appropriately.

        (syms_of_keyboard): Allocate it here, and staticpro it.
        * keyboard.h (this_command_keys): Extern declaration changed.  Doc fix.
        * callint.c (Fcall_interactively): Change handling of 'e' spec;
        this_command_keys is now a vector.

        * keyboard.c (read_char): Call ourselves with the appropriate
        number of arguments.
        (read_char_menu_prompt): If USED_MOUSE_MENU is zero, don't try to
        store things in it.

        (Qlive_window_p): Extern declaration for this.
        * window.c (decode_window): Use CHECK_LIVE_WINDOW instead of
        CHECK_WINDOW; the only thing a user should be able to do to a dead
        window is check its type.
        (Fcoordinates_in_window_p, Fnext_window, Fprevious_window,
        Fdelete_other_windows, Fselect_window, Fsplit_window,
        Fscroll_other_window): Use CHECK_LIVE_WINDOW instead of

        * xmenu.c (Fx_popup_menu): Same.
        * window.c (Fdelete_window): If WINDOW is a deleted window, do nothing;
        there's no harm in allowing people to delete deleted windows.
        Delete all of WINDOW's subwindows, too.
        (delete_all_subwindows): Set the buffer, vchild, and hchild of the
        windows we delete all to nil.
        * window.h (struct window): Doc fix.

        * window.c (Fwindow_minibuffer_p): Make the WINDOW argument
        optional, like all the other window-querying functions.

        * window.c (Fpos_visible_in_window_p): Use decode_window to handle
        the WINDOW argument, instead of writing out that function's code.

        * window.c (check_frame_size): Don't define this extern; that
        doesn't mean anything.

        * xterm.c: Clean up some of the caps lock handling:
        (x_shift_lock_mask): New variable.
        (x_find_modifier_mappings): Set it, based on the modifier mappings.
        (x_convert_modifiers): Use x_shift_lock_mask, instead of assuming
        that the lock bit always means to shift the character.
        (XTread_socket): When handling KeyPress events, don't pass an
        XComposeStatus structure along to XLookupString.  When handling
        MappingNotify events, call XRefreshKeyboardMapping for both
        MappingModifier and MappingKeyboard events, not just the latter.

1992-10-15  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * window.c (Fdelete_window): Choose an alternative when we delete
        any frame's selected window, not just when we delete the selected
        frame's selected window.

        * vm-limit.c (morecore_with_warning): Removed.
        (check_memory_limits): New fn; most code from
        morecore_with_warning, but only checks limits, doesn't do any work.
        (memory_warnings): Set __after_morecore_hook to check_memory_limits;
        don't set __morecore.

1992-10-14  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * intervals.c (traverse_intervals): New parameter `depth'.

        accessing macros.

        * scroll.c (do_scrolling): Don't bcopy non-existant `nruns' or
        `face_list' elements.  Do copy new `max_ascent' frame element.

        `nruns' and 'face_list' removed.  Handle new element `max_ascent'.
        (free_frame_glyphs): Don't free nonexistent elements `nruns' and
        `face_list';  do free `max_ascent' element.
        (make_frame_glyphs): Don't allocate nonexistent elements `nruns'
        and `face_list';  do allocate `max_ascent' element.
        (update_frame): Replaced use of macro LINE_HEIGHT with element
        frame element `pix_height'.

        click_modifier bit on otherwise unmodified mouse clicks.

        * keymap.c (store_in_keymap): Don't forget to QUIT in the

        they're the wrong length.

1992-10-12  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * keyboard.c (kbd_buffer_get_event): Remember that
        *mouse_position_hook may set *FRAME to 0; don't generate
        switch-frame events in this case.  Fix fencepost bug in fetching
        events from keyboard buffer.

1992-10-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        instead, use stddef.h.  Define POINTER, SIZE, EXCEEDS_LISP_PTR.
        * vm-limit.c [!emacs]: Don't include config.h or lisp.h;
        instead, use stddef.h.  Define POINTER, SIZE, EXCEEDS_LISP_PTR.

1992-10-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * keyboard.c (Vlast_event_frame): Make this variable exist even
        when MULTI_FRAME isn't #defined.  People might find it
        necessary for writing correct programs, even when the programs
        don't explicitly use multiple frames.
        (read_char, kbd_buffer_store_event, kbd_buffer_get_event): No need
        to test MULTI_FRAME before setting Vlast_event_frame.

        (unread_switch_frame): New variable.
        (read_key_sequence): Don't throw away the key sequence if the user
        switches frames in the middle of the sequence.  Instead, when we
        receive a switch-frame event in the middle of a key sequence, save
        it, and stuff it into unread_switch_frame when the sequence
        is complete.
        (read_char): If unread_switch_frame is set, return that value.
        (command_loop_1): No need to check Vlast_event_frame and select
        new frames here; that's taken care of by switch-frame events now.
        (syms_of_keyboard): Initialize and staticpro unread_switch_frame.
        * keyboard.h (Qswitch_frame): Declare this extern.

        * frame.c: #include "commands.h" and "keyboard.h".

        non-ascii keys.
        * ymakefile: Note that frame.o depends on commands.h and keyboard.h.

        * callint.c (Fcall_interactively): Allow multiple 'e' specs.
        (Finteractive): Doc fix.
        * keyboard.h (this_command_keys, this_command_key_count): Added

        * keymap.c (access_keymap): Treat bindings for Qt as default
        bindings, when new argument T_OK is non-zero.
        (get_keyelt, Fdefine_key, Flookup_key): Call access_keymap with
        T_OK false.
        * keyboard.c (follow_key, read_key_sequence): Call access_keymap
        with T_OK true.

        * keyboard.c (apply_modifiers): Copy the value of BASE's
        Qevent_kind property to the new symbol.

        * keyboard.c (syms_of_keyboard): Qevent_kind should be initialized
        to intern ("event-kind"), not intern ("event-type").

1992-10-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c (Fwrite_region): If VISIT is a file name,
        use that as file name to visit, and print it in the message.
        Use it for file locking too.

        * m-ibmps2-aix.h [__GNUC__ >= 2] (LIB_STANDARD): Don't define.

1992-10-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

        * ymakefile (FLOATSUP): Renamed to FLOAT_SUPPORT.
        (FRAME_SUPPORT, VMS_SUPPORT): New macros.
        (lisp): Rebuild this from loadup.el, using the _SUPPORT macros.

        * ymakefile [HAVE_X_WINDOWS, not NO_X_MENU, HAVE_X11] (LIBXMENU):
        Link against -loldX, to get the association table functions.

        * xterm.c, xrdb.c: #include <stdio.h> before "xterm.h", to avoid
        warnings about redefining NULL under GCC 2.2.2.

1992-10-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * m/pyrmips.h: New file.

        * s/aix3-1.h (PTY_ITERATION, etc.): Defined.
        (FIRST_PTY_LETTER): Deleted.

1992-10-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * m/sparc.h: Include <sys/param.h>, to define the FSCALE constant.

        * ymakefile (YMF_PASS_LDFLAGS): Refer to the prefix-args program
        using "./prefix-args", not just "prefix-args"; some people don't
        have . in their paths.

1992-10-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * link.com: Use gcclib if compiling with GCC.

        * fileio.c (directory_file_name): Don't clobber the envvar
        when handling top-level rooted dir.

        * ymakefile (LIB_STANDARD): If ORDINARY_LINK, default this to empty.

        * m/ibmps2-aix.h [USG_SHARED_LIBRARIES]: Define ORDINARY_LINK.
        Undef LIB_STANDARD.  Modify LD_SWITCH_MACHINE.

        * unexnext.c: New file.
        * emacs.c (main) [NeXT]: Call malloc_jumpstart.

1992-10-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * window.c (window_loop): Pass 2nd arg to Fother_buffer.
        * frame.c (make_frame): Likewise.
        * callint.c (Fcall_interactively): Likewise.
        * buffer.c (Fkill_buffer): Likewise.
        (Fswitch_to_buffer, Fpop_to_buffer, Fbury_buffer): Likewise.

1992-10-03  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * keyboard.c (read_key_sequence): Treat mouse clicks on non-text
        areas as if they were prefixed with the symbol denoting the
        area clicked on - `mode-line', etcetera.
        When we throw away an unbound `down-' event, reset mock_input as
        well.

        * keyboard.c (Qevent_symbol_element_mask, Qmodifier_cache): Two
        new symbols, used to implement caches on event heads.  These take
        the place of some of the caching that modify_event_symbol used to do.
        (parse_modifiers_uncached, apply_modifiers_uncached,
        lispy_modifier_list, parse_modifiers, apply_modifiers): New
        functions, which replace format_modifiers and reorder_modifiers;
        they can be useful elsewhere too.
        (reorder_modifiers, modify_event_symbol): Re-implement these in
        terms of parse_modifiers and apply_modifiers.  modify_event_symbol
        now uses a much simpler cache, and takes advantage of the caches
        maintained by parse_ and apply_modifiers.
        (follow_key): Don't modify NEXT if KEY has no bindings.
        (read_key_sequence): Drop unbound `down-' events, and turn unbound
        `drag-' events into clicks if that would make them bound.  This
        benefits from the rewriting of the modifier key handling code.
        (syms_of_keyboard): Initialize and intern
        Qevent_symbol_element_mask and Qmodifier_cache.

        * keyboard.c (echo_prompt): Terminate the echo buffer properly
        even when the string is too long to display in the minibuffer.
        (echo_truncate): Just return echoptr - echobuf, rather than
        calling strlen on echobuf.

        * alloc.c (Fmemory_limit): New function.
        (syms_of_alloc): Defsubr it.

        * window.c (SAVE_WINDOW_DATA_SIZE): Define this using sizeof,
        instead of just saying it's 7; that way, we won't get screwed if 
        we add members to struct save_window_data.

        * window.c (struct save_window_data): Save the currently selected
        frame, too.
        (Fset_window_configuration): Restore the frame's selected window
        using Fselect_window, and then restore the selected frame using
        Fselect_frame.
        (Fcurrent_window_configuration): Record the currently selected
        frame.  Update docstring to describe the information now recorded.

1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * process.c (wait_reading_process_input): Ultrix select seems to
        return ENOMEM when interrupted.  So, under Ultrix, treat ENOMEM
        like EINTR.

        * keyboard.c (modifier_names): The modifier is named "control",
        not "ctrl".

        * keyboard.c (modify_event_symbol): Make sure that the unmodified
        event header gets the proper properties set on it, by recursing
        and letting the same code build the properties for all event symbols.

        * keyboard.c (Qmouse_click): Fix typo which assigned `mouse-click'
        symbol to Qmouse_movement.

1992-10-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * undo.c (Fprimitive_undo):
        When undoing an insert, move point and then delete.

1992-10-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * intervals.c: `copy_intervals' no longer static.

        * intervals.h: Declare `copy_intervals'.

        * buffer.c: #include intervals.h.

        * ymakefile: New macro "INTERVALS", controlled by "USE_INTERVALS",
        which defines the interval include file "intervals.h".
        New entries for "intervals.c" and "textprop.c".

        * lisp.h: Declare Qbuffer_or_string_p.

1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xterm.c (x_find_modifier_meanings): If there are no
        modifiers containing a Meta_ keysym, use the Alt keysyms to
        denote meta.
        (construct_mouse_click): Set the down_modifier bit on mouse
        button press events.
        (XTread_socket): When processing keypress events, use
        x_meta_mod_mask when processing ordinary ASCII characters, not
        just when processing function keys and other non-ASCII events.
        (XTread_socket): If we receive a MappingNotify event with the
        `request' member set to `MappingModifier', then call
        x_find_modifier_meanings to refresh x_meta_mod_mask.

        * window.c (Fset_window_configuration): Clean up the way we save
        and restore the frame's size.

        * termhooks.h (struct input_event): Doc fix.
        (NUM_MOUSE_BUTTONS): New constant.
        (click_modifier): New modifier.
        (NUM_MODIFIER_COMBOS): Removed.

        * keyboard.h (EVENT_HAS_PARAMETERS): Definition changed - all events
        are not 5 elements long.
        (EVENT_HEAD): Work correctly on all sorts of events, not just
        events with parameters.
        (EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
        EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
        anymore; this information may appear twice in an event.  These
        are replaced by the POSN_ accessors, which are meant to be
        composed with the EVENT_START and EVENT_END accessors.
        (EVENT_START, EVENT_END): Two new accessors, to get at the
        starting and ending position of an event.
        (POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
        POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
        diasassemble the values returned by EVENT_START and EVENT_END.
        * keyboard.c (echo_char, read_char): Apply EVENT_HEAD without first 
        testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
        all sorts of events now.
        (read_key_sequence): Use the new accessors to decide in which window
        an event occurred.
        * keymap.c (access_keymap, store_in_keymap,
        Fsingle_key_description): No need to check for
        EVENT_HAS_PARAMETERS before using EVENT_HEAD; the latter now
        works properly on all sorts of events.

        * keyboard.c (Qevent_unmodified): Replaced by...
        (Qevent_symbol_elements): New property.
        (syms_of_keyboard): initialize and staticpro the latter, not the
        former.
        * keyboard.h (Qevent_unmodified): Extern declaration replaced by...
        (Qevent_symbol_elements): This.
        (EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
        property, rather than the Qevent_unmodified property.

        * keyboard.c (readable_events): This doesn't need to scan and
        discard mouse release events anymore; it just uses
        EVENT_QUEUES_EMPTY.
        (kbd_buffer_get_event): No need to skip past mouse release events.

        * keyboard.c (button_down_location): New variable, which
        stores the location at which each button was pressed, so we
        can build a complete drag event when the button is released.
        (make_lispy_event): When a button is pressed, record its
        location in button_down_location, and turn it into a `down'
        event.  When a button is released, compare its release
        location with its press location, and decide whether to call
        it a `click' or `drag' event.
        Change mouse movement events to be arranged like click events.
        (format_modifiers): Note that the click modifier has no
        written representation.
        (modifier_names, modifer_symbols): New variables, used to
        create the Qevent_symbol_elements property.
        (modify_event_symbol): Change the format of the modified
        symbol cache; there are too many modifier bits now to use a
        vector indexed by a modifier mask.  Use an assoc-list instead.
        Document the format of the cache.
        Put the Qevent_symbol_elements property on each new symbol,
        instead of a Qevent_unmodified property.
        (symbols_of_keyboard): Put Qevent_symbol_elements properties on
        the symbols specified in head_table, not Qevent_unmodifed properties.
        Initialize and staticpro modifier_symbols, and staticpro the
        window elements of button_down_location.

        * xmenu.c: #include "keyboard.h".
        (Fx_popup_menu): Use the event accessors defined in keyboard.h,
        instead of writing out cars and cdrs.
        * ymakefile: Note that xmenu.o depends on keyboard.h.

1992-10-02  Joseph Arceneaux  (jla@wookumz.gnu.ai.mit.edu)

        * textprop.c: Conditionalize all functions on
        "USE_TEXT_PROPERTIES".
        * intervals.c: Conditionalize all functions on
        "USE_TEXT_PROPERTIES".
        Removed #include of "screen.h".

        * alloc.c: #include "intervals.h".
        (init_intervals, make_interval,
        mark_interval, mark_interval_tree): New functions conditionally
        defined.
        (make_uninit_string): Call INITIALIZE_INTERVAL.
        (INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
        New macros, conditionally defined.
        (mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
        (gc_sweep): If text properties are in use, place all unmarked
        intervals on the free list.  Call UNMARK_BALANCE_INTERVALS on
        `buffer->intervals' when unmarking `buffer'.
        (compact_strings): Include INTERVAL_PTR_SIZE in calculation for
        target of bcopy when relocating strings.
        (init_alloc_once): Call INIT_INTERVALS.
        (make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
        `size'.
        Moved static declaration of `mark_object' and other functions up
        in the file.

        * fileio.c (Finsert_file_contents): Call offset_intervals if
        text was actually inserted.
        #include "intervals.h".

1992-09-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * data.c: Qbuffer_or_string_p added.

        * syntax.c (describe_syntax): Use insert_char to insert `match'.

        * buffer.c (reset_buffer): Do INITIALIZE_INTERVAL on the buffer's
        interval component.
        (Fkill_buffer): Likewise.

        * editfns.c (make_buffer_string): Call copy_intervals_to_string.
        (Finsert_buffer_substring): Call graft_intervals_into_buffer.
        #include "intervals.h".

        * insdel.c: #include "intervals.h"
        (prepare_to_modify_buffer): Call verify_interval_modification.
        (insert_from_string): Call offset_intervals and
        graft_intervals_into_buffer.
        (del_range): Call offset_intervals.
        (insert): Call offset_intervals.

        * emacs.c: #include "intervals.h".
        (main): Call syms_of_textprop.  This is only really present if
        Emacs is compiled with USE_TEXT_PROPERTIES defined.

        * buffer.h: New macro TEMP_SET_PT.  If intervals are used, SET_PT
        and TEMP_SET_PT are function calls.
        Similarly for BUF_SET_PT and BUF_TEMP_SET_PT.
        Added DECLARE_INTERVALS to buffer structure to conditionally
        compile an interval tree into it.

        * intervals.h: Declare temp_set_point.

1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * ymakefile (config.h): Doc fix.

1992-09-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * config.h.in: Added a slot for definition of USE_TEXT_PROPERTIES,
        controlling compilation of interval code.
        If using GNUC, support inline functions.

        * lisp.h: Conditionally define interval structure and macros.
        Add DECLARE_INTERVALS to struct Lisp_String.

1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * buffer.c (Fother_buffer): Add back the VISIBLE_OK argument.  It
        got removed with no comment or ChangeLog entry, and
        append-to-buffer uses it.

        * window.c (struct save_window_data): Add a member called
        focus_frame, to save and restore the screen's focus frame.
        (Fset_window_configuration): Redirect the frame's focus as
        indicated in the window configuration.
        (Fcurrent_window_configuration): Record the frame's current focus.
        * minibuf.c (read_minibuf): Don't bother to save the current
        frame's focus, and have read_minibuf_unwind restore it; saving and
        restoring the window configurations will take care of that.
        (read_minibuf_unwind): Don't worry about restoring the frame's focus.

        * window.c (Fset_window_configuration): Don't select the frame
        just because we restored its configuration.

        * window.c (Fset_window_configuration): Don't forget to set the
        frame's selected window when we can't call Fselect_window.

        * xterm.c (x_meta_mod_mask): New variable, indicating which X
        modifier bits denote meta keys.
        (x_find_modifier_meanings): New function, to set x_meta_mod_mask.
        (x_convert_modifiers): Use that.
        (x_term_init): Call x_find_modifier_meanings.

        * data.c (Fmake_local_variable): If SYM forwards to a C variable,
        swap in the value for the current buffer immediately.

        * lisp.h: Doc elaboration for Lisp_Buffer_Local_Value.

1992-09-29  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * textprop.c (Ferase_text_properties): Merge intervals when
        possible.

1992-09-29  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xselect.c (Qcut_buffer0): Symbol removed; we're using a new
        interface to the cut buffer now.
        (NUM_CUT_BUFFERS, cut_buffer_atom, cut_buffer_value,
        cut_buffer_cached, cut_buffer_just_set): New variables.
        (Fx_own_selection, Fx_selection_value): Dike out the code to
        handle CUT_BUFFER0 requests.
        (Fx_get_cut_buffer, Fx_set_cut_buffer, x_watch_cut_buffer_cache,
        x_invalidate_cut_buffer_cache): New functions.
        (syms_of_xselect): Don't bother to initialize Qcut_buffer0.
        Initialize and staticpro cut_buffer_value, and defsubr
        Sx_get_cut_buffer and Sx_set_cut_buffer.
        * xterm.c (XTread_socket): Pass PropertyNotify events from the
        root window to x_invalidate_cut_buffer_cache.
        (x_term_init): Call x_watch_cut_buffer_cache here.

        * keymap.c (access_keymap): Don't forget to QUIT while scanning
        the keymap.

        * keyboard.c (recent_keys): This needs to be staticpro'ed.  Change
        it from a C array, which is a pain in the neck to staticpro, into
        a lisp vector, which is easier.
        (read_char, Frecent_keys): Access recent_keys as a lisp vector,
        not a C array.
        (syms_of_keyboard): Set recent_keys to be a vector, and staticpro it.

        * ymakefile (xfns.o): This doesn't depend on xselect.c.

        * xterm.h (ROOT_WINDOW): Use the DefaultScreen macro, not the
        XDefaultScreen function.

        * frame.c (Fdelete_frame): Call Fselect_frame with the appropriate
        number of arguments.

        * data.c (Frem): Use the `fmod' function under SunOS, Ultrix, and
        HP/UX, not just under USG systems.

        * buffer.c (Fbury_buffer): This used to undisplay the buffer being
        buried only if the BUFFER argument was nil.  Instead, undisplay the
        buffer whenever it's displayed in the selected window, no matter
        how it was specified by BUFFER.  This is how it behaves in 18.58,
        and I can't find any ChangeLog entry in 18.58 or 19.0 saying why
        they differ.  Fix the doc string accordingly.

1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * frame.c (Fselect_frame, Fframe_root_window,
        Fframe_selected_window, Fnext_frame, Fmake_frame_visible,
        Fmake_frame_invisible, Ficonify_frame): Doc fixes.

        * ralloc.c: Since the users of the relocating allocation code
        handle memory exhaustion, it's better to return an error code to
        them than to call abort. 
        (obtain): If we cannot allocate more memory, don't call
        abort.  Instead, return non-zero iff the allocation is successful.
        (get_more_space): If obtain fails, return zero.
        (get_bloc): Return zero if we can't allocate the new bloc.
        (r_alloc_sbrk): Return zero if we can't allocate more memory.
        (r_alloc): If we can't allocate more memory, set *PTR to zero and
        return zero.
        (r_re_alloc): If we can't allocate more memory, leave *PTR
        unchanged, and return zero.

        * ralloc.c (warnfunction): Renamed to warn_function; users changed.

1992-09-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * insdel.c (del_range): Call record_delete before updating point.

        * fileio.c (Finsert_file_contents): Do record_insert, then inc MODIFF.

        * undo.c (record_delete): Record pos before the deletion.
        (Fprimitive_undo): Go back to recorded position.

1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * window.c (delete_all_subwindows): Save the window's buffer in
        its `height' field; we may need to know the window's old buffer
        once we have restored it from a window configuration.
        (Fset_window_configuration): When we restore a window, if its
        `height' field is a buffer, restore its `buffer' field from that.
        This allows us to leave the window's buffer unchanged if the
        buffer recorded in the configuration is dead.

        * window.c (delete_all_subwindows): Removed unused variable named
        "count".

1992-09-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * keyboard.c (read_char): If we're returning an event from a
        macro, set Vlast_event_frame to Qmacro, instead of leaving it set
        to the frame of the previous real event.
        (read_key_sequence): If Vlast_event_frame isn't a frame, don't
        bother switching buffers.
        (syms_of_keyboard): Doc fix for Vlast_event_frame.
        (Vlast_event_frame): Doc fix.

        * termhooks.h (alt_modifier, hyper_modifier, super_modifier,
        down_modifier, drag_modifier): New modifiers, to support the new
        input system.  Re-arranged modifiers so that their bits are in
        canonical order; this makes reorder_modifiers slightly simpler.
        * keyboard.c (format_modifiers, reorder_modifiers): Handle the new
        modifier bits.

        * keymap.c (access_keymap): Remove code to notice bindings for
        Qt.

1992-09-25  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xmenu.c (single_keymap_panes): Handle vectors properly.

1992-09-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * keymap.c (Fwhere_is_internal): Don't forget to advance map to
        the next element when we find something that is neither a vector
        nor a cons.  Don't forget to QUIT in the appropriate places,
        either.

1992-09-23  Joseph Arceneaux  (jla@geech.gnu.ai.mit.edu)

        * textprop.c (Fset_text_properties): Merge adjacent intervals with
        the same properties.
        (Fnext_single_property_change, Fprevious_single_property_change):
        New subrs.

        * intervals.c (merge_interval_left, merge_interval_right): Abort
        if caller tries to merge first (or last, respectively) interval.
        Delete the interval node after merging.
        (copy_intervals): Use `split_interval_right' rather than creating
        new intervals with make_new_interval and attaching them
        explicitly.
        (verify_interval_modification): Changed error message.  GCPRO
        hooks before calling Fnreverse, and correctly Fcdr down the list.
        Also, don't cons multiple copies of the same consecutive
        modification hook.
        (temp_set_point): New function.
        (set_point): Call point-left and point-entered hooks if moving
        between text with different properties.  Use the old and new
        positions as arguments to these calls.

        * intervals.c, intervals.h: (map_intervals, make_buffer_interval,
         make_string_interval,run_hooks): Deleted.

1992-09-23  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * keymap.c (DENSE_TABLE_SIZE): Doc fix.
        (keymap_table): Function removed; this function exists only to
        support an incorrect understanding of the format of keymaps.
        (access_keymap, store_in_keymap, Fcopy_keymap,
        Faccessible_keymaps): Correctly handle vectors at any point in the
        keymap; don't assume it must be at the front.
        (describe_map): Instead of calling describe_vector on the vector
        in the cadr of the keymap (if present) and then calling
        describe_alist to do the rest, just call describe_map_2.
        (describe_alist): Renamed to describe_map_2; call describe_vector
        when we encounter a vector in the list.
        * xmenu.c (single_keymap_panes): Comment out the code which
        tries to handle a dense keymap's table; it uses keymap_table, and
        the rest of the code never uses the table contents anyway.

        * keymap.c (access_keymap, store_in_keymap): Clarify error message
        for non-ASCII characters.

        * process.c [SIGCHLD && !BSD && !UNIPLUS && !HPUX]
        (create_process): #if 0 out the code which sets the child's
        handler for SIGCHLD to sigchld; the code which gives sigchld its
        value has been diked out under these CPP symbols, so this should
        be diked out too.

        * indent.c (Fmove_to_column): Pass the right number of arguments
        to Findent_to.

1992-09-22  Jim Blandy  (jimb@kropotkin.gnu.ai.mit.edu)

        * emacs.c (emacs_priority): Doc fix.
        (main): Use nice, not setpriority; we just need a
        simple, portable call to nice here.
        * callproc.c (child_setup): Use nice, not setpriority.
        * sysdep.c (sys_suspend): Don't try to use "nice (- nice (0))" to
        set the subshell's priority to normal; nice doesn't return a
        defined value on all systems.  Instead, since emacs_priority gives
        the priority that Emacs was nastied to, we can use it to reset the
        priority in a straightforward way.
        [BSD4_1], [USG], [VMS] (setpriority): Remove dummy and
        compatibility definitions of setpriority.

        * keymap.c (access_keymap): Return the binding of Qt as the
        binding for all unbound characters.

        * fileio.c (syms_of_fileio): Don't try to defsubr Sunix_sync
        unless it's actually been defined - that is, if unix is #defined.

        * xrdb.c (x_get_resource): Cast the value being assigned to
        ret_value->addr, rather than ret_value->addr itself; only GCC
        allows you to cast lvalues.

        * eval.c (unbind_catch): Do the long-jump here.  Take a VALUE
        argument, which specifies the value to return to the catch, or the
        data to give to the condition handler.  Renamed to
        unwind_to_catch, to reflect new role.
        (Fsignal, Fthrow): Removed code to set catch tag value and do the
        long-jump; this is taken care of by unwind_to_catch.

1992-09-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * alloc.c (mark_object): Avoid car recursion on cons with nil in cdr.
        Avoid recursion on constants-vector of a compiled function.

        * oldXMenu: Symlink deleted; anything that uses it needs fixing
        in any case to work properly on systems without symlinks.

1992-09-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/sol2.h: New file.

        * fileio.c: Don't include sys/dir.h.

        * s/usg5-4.h (LIBS_SYSTEM): Move non-default libraries here.
        (LIB_STANDARD, START_FILES): Deleted.
        (ORDINARY_LINK): Defined.

        * ymakefile [ORDINARY_LINK]: Default LD to $(CC)
        and make START_FILES and LIB_STANDARD empty.
        (C_SWITCH_X_MACHINE, C_SWITCH_X_SYSTEM): New macros, default empty.
        (CFLAGS): Use them.

1992-09-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * ymakefile (${etc}DOC): Use OBJECTS_SYSTEM and OBJECTS_MACHINE.

        * dired.c [VMS]: Include string.h, rms.h, rmsdef.h.
        [VMS] (Ffile_version_limit): New function.

        * sysdep.c (sys_suspend): Read EMACS_PARENT_PID envvar for parent. 

        * syntax.c (scan_lists): When searching back for comment:
        if comment-end is 2 chars, assume it does end a comment.
        Otherwise, scan back to previous comment-end to see if there's
        a comment starter between.  Also record whether the string quotes
        between the start and the end are paired and uniform.
        If so, skip to comment starter.  If not, scan from start of
        defun to find comment starter if any.
        (find_defun_start): New function.

        * alloc.c (mark_object): Save last 500 values of objptr.
        Check for clobberage of ptr, when marking a vector.

1992-09-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keymap.c (get_keyelt): Skip menu help string after menu item name.

1992-09-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * buffer.c (Fget_buffer_create): Doc fix.

        * lisp.h (struct handler): Remove the poll_suppress_count member
        of this structure; it is always equal to the poll_suppress_count
        of its catchtag structure.  The non-local exit code in eval.c is
        difficult enough to understand as it is; needless duplication
        doesn't help.
        * eval.c (Fcondition_case): Rearranged for clarity.  Don't worry
        about setting h.poll_suppress_count; it's guaranteed to be the
        same as c.poll_suppress_count.
        (internal_condition_case): Don't worry about
        h.poll_suppress_count.
        (Fsignal): Use h->tag->poll_suppress_count instead of
        h->poll_suppress_count.

        * eval.c (Fsignal): It's okay for the debugger to return to the
        caller if the caller was signalling a quit.

        * eval.c (unbind_catch): Restore the polling suppression count
        here, instead of in Fsignal and Fthrow.
        (Fthrow, Fsignal): Don't restore the polling suppression count here.
        
        * lisp.h (struct specbinding, struct handler): More documentation.
        * eval.c (struct catchtag): More documentation.

1992-09-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * ymakefile (LIBX): Don't use -loldX.

1992-09-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * minibuf.c (get_minibuffer): Enable undo in minibuffers.

1992-09-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * ymakefile (LIBXMENU): Check NO_X_MENU, not HAVE_X_MENU
        * emacs.c (main): Use X menu code if HAVE_X_WINDOWS and not NO_X_MENU.
        * keyboard.c (read_char_menu_prompt): Likewise.

        * config.h.in: Delete everything about config.h.

        * emacs.c: Eliminate HIGHPRI as compilation option.
        (emacs_priority): New C variable, also Lisp variable.
        (main): Set the priority iff emacs_priority is nonzero.

1992-09-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * eval.c (entering_debugger): Variable renamed
        when_entered_debugger, and is now a timestamp based on
        num_nonmacro_input_chars.
        (init_eval): Initialize when_entered_debugger, not
        entering_debugger.
        (call_debugger): Set when_entered_debugger to the current value of
        num_nonmacro_input_chars.
        (find_handler_clause): Don't call debugger unless
        num_nonmacro_input_chars is greater than when_entered_debugger;
        that way, we won't call the debugger unless the user has had a
        chance to take control.
        (Fbacktrace): Don't clear entering_debugger here.
        * keyboard.h (num_nonmacro_input_chars): Added extern declaration
        for this.

        * fns.c (Fy_or_n_p): After testing for a QUIT, clear Vquit_flag.
        Otherwise, if Fy_or_n_p is called while Vinhibit_quit is true and
        the user presses C-g, this function goes into an infinite loop.

        * dispnew.c (get_display_line): Don't abort if the frame is
        invisible; since unmap events are handled at the interrupt level,
        a screen may become invisible at any time.

1992-09-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c (Fverify_visited_file_modtime):
        Pass buffer itself to handler, if have handler.
        (Fwrite_region): GCPRO around Fexpand_file_name, Ffile_name_directory.
        (Fread_file_name_internal): GCPRO around file name manip.
        (Ffile_writable_p, Ffile_readable_p): Use abspath, not filename,
        (Ffile_executable_p, Ffile_exists_p): to run the handler.
        (Fset_file_modes, Ffile_directory_p, Ffile_modes): Likewise.
        (Ffile_newer_than_file_p): GCPRO around expand_and_dir_to_file.

1992-09-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * s/bsd4-3.h: Give the BSD4_3 and BSD symbols the same numeric
        definitions they'll get in <sys/param.h>, to avoid warnings.

        * m/hp9000s300.h: Don't include <sys/wait.h>.  This really
        shouldn't be necessary.
        (BIG_ENDIAN): Define this as "4321", to agree with
        <machines/endian.h>, and avoid warnings.

        * systime.h: Re-arrange inclusion of <sys/time.h> and <time.h> so
        that they don't both get included under BSD, and do both get
        included under AIX.

        * xdisp.c (display_mode_line): If the only other frames are
        minibuffer frames, don't name the frame after the in the selected
        window.  We can use Fnext_frame to do this test easily.

1992-09-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * process.c (Faccept_process_output): Initialize useconds.

        * keyboard.c (num_nonmacro_input_chars): New variable.
        (read_char): Use num_nonmacro_input_chars to decide on auto-save & gc.
        Increment it when appropriate.
        (record_auto_save): Use num_nonmacro_input_chars.

        * fileio.c (Ffile_name_directory, Ffile_name_nondirectory): 
        (Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name): 
        Call find_file_handler.
        (syms_of_fileio): Set up Qfile_name_directory, etc.
        (Fcopy_file): Call find_file_handler for newname as well as for filename.
        (syms_of_fileio): Initialize Vfile_name_handler_alist.

1992-09-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callint.c (Fcall_interactively): Remove the 'K' interactive
        code, in favor of 'e'; that's a better name.

1992-09-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s/esix5r4.h: New file.

        * sysdep.c (init_sys_modes): Handle VDSUSP like V_DSUSP.
        Use CDISABLE, not CDEL.
        Turn off IEXTEN if it exists.
        * systty.h (CDISABLE): New macro; may be defined from CDEL.

        * keyboard.c (command_loop_1): Bind inhibit-quit to t when in Fsit_for.

1992-09-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * Makefile.in: Add comments starting with "# DIST: " explaining
        that this gets munged by the configure script.

1992-09-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * s-aix3-1.h (HAVE_GETHOSTNAME): Defined.

1992-09-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * frame.c (choose_minibuf_frame): abort if the selected frame has
        nil in its minibuffer_window slot; this shouldn't happen any more.
        * window.c (minibuffer_window): Accept an optional FRAME argument;
        if specified, return the minibuffer used by that frame.

        * keymap.c (describe_buffer_bindings): Adjust key_heading to match
        the format used by describe_map_tree.  Also, don't reprint the
        "key    binding" header above the global bindings if we've already
        printed it for the local bindings; it's clear enough that the
        columns mean the same thing as above.

1992-09-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * ralloc.c (r_re_alloc): Instead of allocating a new bloc at the
        end of the heap, copying the data to it, and then freeing the
        original bloc, just expand the original block.  This saves a copy
        and a call to sbrk, and also removes the large spike in memory
        allocation that would occur when resizing large buffers.  And it's
        less code.

        * keyboard.h (Vkeyboard_translate_table): Declare this extern
        here, so describe_buffer_bindings can use it.
        * keymap.c (describe_buffer_bindings): Declare buf and bufend...

1992-09-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * systime.h: Always #include <time.h>, not just when NEED_TIME_H
        is defined.  It gets us struct tm.  #include <sys/time.h> whenever
        HAVE_TIMEVAL is defined and NEED_TIME_H isn't.

        * systime.h: Note that the tz_dsttime field of the struct timezone
        returned by gettimeofday doesn't say whether daylight savings is
        _currently- active; rather it specifies whether it is *ever*
        active.
        (EMACS_GET_TZ_OFFSET_AND_SAVINGS): Removed `savings_flag'
        argument, and renamed to EMACS_GET_TZ_OFFSET.  Don't try to
        extract savings information.  EMACS_CURRENT_TIME_ZONE should call
        localtime to figure out whether DST is active.

        * m/hp9000s300.h: #include <sys/wait.h> before doing anything
        else, to avoid conflicts between the system's and Emacs's
        definitions of BIG_ENDIAN.

        * keymap.c (describe_buffer_bindings): Set the current buffer to
        descbuf before calling current_minor_maps; that function's value
        depends on the values of buffer-local variables.  Don't set the
        current buffer to Vstandard_output until afterwards.

        * keymap.c (describe_buffer_bindings): If
        Vkeyboard_translate_table is in effect, describe its effects.

        * frame.c (Fnext_frame): Doc fix.

        * frame.c (prev_frame): #if 0'd out; nobody uses this.

        * frame.c (next_frame): The logic which determines whether a frame
        is acceptable to return was misarranged; rewrote it.
        (prev_frame): Same thing.

1992-09-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * syntax.c (scan_lists): Improve smarts for backwards scan of comments.
        Don't modify comstyle inside that loop.
        If string quotes don't match up, don't take value from OFROM;
        instead, parse forward using scan_sexps_forward.
        (scan_sexps_forward): Return value via a pointer passed in.
        New element in state contains char addr of last comment-starter seen.
        (Fparse_partial_sexp): Change call to scan_sexps_forward.

1992-09-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xmenu.c (xmenu_show): If no panes, just return.

        * keyboard.c (last_nonmenu_event): New var.
        (syms_of_keyboard): New Lisp var.
        (read_key_sequence): Use that instead of prev_event.
        * commands.h (last_nonmenu_event): Declared.
        * callint.c (Fcall_interactively): For `K', use last_nonmenu_event.
        Make `e' alias for `K'.

1992-09-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * editfns.c (Fcurrent_time_string): Change docstring to
        indicate that we will probably add the timezone to the end,
        now that we have it available on many systems.

        * xrdb.c: Don't include <X11/Xos.h>.  Under R4, it stupidly
        insists on defining SIGCHLD, even if it already has a definition.
        (file_p): Use the constant 4 instead of R_OK; empirically, the
        number is more portable than the symbol if you count the #include
        hair you have to go through to get R_OK defined.  Ffile_readable_p
        does this too.

        * xterm.c (x_wm_set_size_hint): Set the base_width and base_height
        members of size_hints, if they're available (X11R4 and after);
        otherwise, approximate the right thing, by using min_width and
        min_height as the base size.

1992-09-02  Barry A. Warsaw   (warsaw@anthem.nlm.nih.gov)

        * Extended syntax.c in the following ways to support up to 2
        orthogonal comment styles per mode.  This is needed for C++.
        Bit 6 of syntax table entry for a character indicates
        it is part of the `b' comment style.  Otherwise it is
        part of the `a' style.
        * syntax.h (SYNTAX_COMMENT_STYLE): New macro.
        * syntax.c (Fmodify_syntax_entry): Set that flag for `b'.
        (describe_syntax): Print the `b' flag.
        (scan_lists, scan_sexps_forward): Handle the new flag.
        (Fparse_partial_sexp): Return new element in value.

1992-09-02  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * fileio.c (syms_of_fileio): Doc fix for Vfile_name_handler_alist.

1992-09-02  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * keyboard.c (kbd_buffer_get_event): When performing the
        FRAME_FOCUS_FRAME redirection, don't modify the frame field of
        the event; that fatally corrupts mouse click events.  Instead,
        just perform the redirection on the value assigned to
        Vlast_event_frame.

        * callint.c (Fcall_interactively): Don't try to get the
        `enable-recursive-minibuffers' property from FUNCTION unless
        FUNCTION is actually a symbol; there are some cases where a key
        sequence is bound directly to a lambda form, and there's no reason
        to break these.

        * window.c (Fset_window_configuration): Don't signal an error
        if the frame size saved in the window configuration doesn't
        match the frame's current size; instead, temporarily resize
        the frame while installing the window configuration.  This is
        important because using the minibuffer saves and restores the
        current window configuration, and you don't want to signal an
        error just because the user resized the frame while using the
        minibuffer.

        * doc.c (Fsnarf_documentation): Signal an error if this is
        called in a dumped Emacs.

        * alloc.c (mark_object): mark a symbol's name after marking its
        value, function, and property list rather than before; this way,
        symbols' names are readable, giving us a chance to detect some
        kinds of heap corruption.

1992-09-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * emacs.c (__main, __do_global_dtors): New dummy functions.
        (__do_global_ctors_aux, __do_global_ctors): Fix typo in fn names.

1992-09-01  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * prefix-args.c: New file.  See comment at top of file.
        * ymakefile (YMF_PASS_LDFLAGS): Use the prefix-args program to
        affix the -Xlinker prefix to the linker arguments.
        (prefix-args): New target.
        (temacs): Depend on prefix-args.

        * xterm.c (x_catch_errors): Don't forget to initialize
        x_caught_error_message to the null string, so x_check_errors can
        tell when an error has occurred.

        * unexmips.c (mark_x): Declare this as static void at the top of
        the file and at the function definition.

        * keyboard.c (input_available_signal): Declare this to return
        SIGTYPE.

        * xrdb.c (getuid): Declare this to return short.

        * s/bsd4-3.h: Remove definition of SIGTYPE macro; Mt. Xinu says
        it's int, but Ultrix says it's void.  Since the SIGTYPE guessing
        code in the `configure' script gives the correct answer for both
        of these cases, there's no point in listing it here.

        * systime.h (EMACS_CURRENT_TIMEZONE): Change documentation to
        indicate that *OFFSET should be set to the number of minutes EAST
        of Greenwich, which is what Ed Reingold says real time gurus want.
        Changed the definition of the EMACS_GET_TZ_OFFSET_AND_SAVINGS
        macro to reflect this.  Buggily, the Fcurrent_time_zone function
        was already expecting minutes east of GMT.

        * Makefile.in (distclean): Remove backups from the `m' and `s'
        directories, too.

        * m/mips.h: Merge changes from Emacs 18.58:
        [NEWSOS5]: Changes so this file can be used with s/newsos5.h.
        (SIGN_EXTEND_CHAR): Define this using a cast to signed char.  I
        guess the MIPS compiler and its derivatives all have this type.
        (HAVE_ALLOCA, C_ALLOCA): Define the former if we're compiling with
        GCC, and the latter otherwise.
        (C_SWITCH_MACHINE): Defined, instead of C_SWITCH_SYSTEM.
        (LINKER): Defined, if BSD.
        (XUINT, XSET, XUNMARK): Add parentheses to eliminate warnings from
        GCC.  Reindent to fit in 80 columns.
        INHIBIT_BSD_TIME prevents including bsd/sys/time.h.
        * s/newsos5.h: New file for Sony NEWS-OS release 5, courtesy of
        Chris Hanson <cph@klia.ai.mit.edu>.

        * m/mips.h: Don't undefine LOAD_AVE_TYPE; the comment says that
        Emacs 19 has the crocks to handle it properly.

        * m/pmax.h: Merge changes from Emacs 18.58:
        (LIB_STANDARD, COFF, TERMINFO): Cancel out definitions from
        m/mips.h which are only appropriate for USG.
        (MAIL_USE_FLOCK, HAVE_UNION_WAIT): Do define these.
        (BROKEN_O_NONBLOCK): Defined.
        (LINKER): Don't define this.
        [OSF1]: Undef C_ALLOCA, define HAVE_ALLOCA.
        
        * s/osf1.h: New file.

        * s/bsd4-3.h: Merge changes from Emacs 18.58:
        (BSD, BSD4_3): Just define these, don't fret about numerical
        values or version numbers.

        * m/hp9000s300.h: Merge changes from Emacs 18.58, and hp300bsd.h:
        Change configuration note to say it's okay to use this file for BSD.
        Add comment saying that NOMULTIPLEJOBS must be defined for
        versions of HP/UX before 6.5.
        Don't define BIG_ENDIAN if it seems that <endian.h> has already
        done so.
        [BSD4_3] Define m68000, instead of hp9000s300; crt0.c uses these
        to decide what sort of startup code to use.
        [not BSD4_3] Under HP/UX, always define the BSD memory functions
        (bcopy, bzero, and bcmp) in terms of the SYSV string functions
        (memcpy, memset, and memcmp), not just under HP/UX 5; version 6's
        BSD compatibility library has reported bugs in `signal'.
        (NEED_BSDTTY): Move this symbol's definition inside the "not
        BSD4_3" conditional, since it's only relevant to HP/UX.
        * m/hp300bsd.h: File deleted, since m/hp9000s300.h now
        works with both HP/UX and BSD; it includes m/hp300bsd.h's
        specifications.

        * m/hp9000s300.h: Remove definition for SIGN_EXTEND_CHAR; this is
        only used by the regexp code, which has its own portable
        definition these days.

1992-08-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keymap.c (Fmake_sparse_keymap): New optional arg.  Callers changed.
        (Fmake_keymap): Likewise.

        * emacs.c (__do_global_ctors, __do_global_ctors_aux): New dummy fns.
        (__CTOR_LIST__, __DTOR_LIST__): New dummy variables.

        * fileio.c (Fdo_auto_save): Always call record_auto_save.

        * keyboard.c (read_char): Call read_char_menu_prompt here.
        Accept 4 new args to pass to it.  Include them in recursive call.
        Don't delay before starting echo if prev_event was a mouse event.
        Test for eof in batch mode now understands C is a Lisp_Object.
        (read_key_sequence): Don't call it here; always call read_char.
        Don't change last_event_buffer after a mouse menu input.
        (read_char_menu_prompt): Arg PROMPT deleted.
        Return nil if nothing to do.

        * xmenu.c (Fx_popup_menu): Treat coords relative to spec'd window.
        (single_keymap_panes): New function; contains guts of keymap_panes.
        If a command binding for submenu has a prompt string starting with @,
        make a separate pane for it at this level.

        * xfns.c (Fx_track_pointer): Pass new args to read_char.
        (Fx_select_region, Fx_horizontal_line): Likewise.
        * lread.c (Fread_char): Pass new args to read_char.
        (Fread_event, Fread_char_exclusive): Likewise.
        * fns.c (Fy_or_n_p): Pass new args to read_char.

1992-08-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c (read_key_sequence): Keep track of prev_event.
        Pass new proper args to read_char_menu_prompt.
        (read_char_menu_prompt): New arg prev_event.  Use Fx_popup_menu.
        Handle any number of keymaps, not just LOCAL and GLOBAL.
        Invert meaning of arg PROMPT.  Test of menu_prompting was backwards.

        * keymap.c (keymap_table): No longer static.

        * xmenu.c (keymap_panes): New function.
        (Fx_popup_menu): Accept keymap or list of keymaps as MENU argument.
        Accept mouse button event as POSITION argument.

1992-08-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * cmds.c (internal_self_insert): Assume Fexpand_abbrev expanded
        something if it incremented MODIFF.

1992-08-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * unexmips.c (unexec): Allow sections in any order.
        Adjust addresses of rdata section as well as data section.

        * buffer.c (syms_of_buffer): Made buffer-display-table,
        buffer-field-list and buffer-undo-list allow any type of value.

1992-08-27  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fns.c (Fappend): Doc fix.

1992-08-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * s/usg5-4.h: Incorporate changes from 18.58:
        (LIBX10_SYSTEM): Undefine this.
        (GNULIB): Definition deleted -- done in ymakefile.
        (LIB_STANDARD): Don't use GNULIB.
        (HAVE_TCATTR): Defined.

        * xfns.c (x_icon): Don't call x_wm_set_icon_positions if the user
        hasn't specified the icon position.  Let the window manager put
        the icon where it likes.

        * xterm.c (x_make_frame_invisible): Don't forget to check the
        return value of XWithdrawWindow; it could indicate that the window
        wasn't successfully redrawn.

        * sysdep.c (init_baud_rate): Re-arranged order of conditionals -
        test TERMIOS before TERMIO; when two options might both be
        defined, test the most recent first, so that the most recent
        functions get used.

        * sysdep.c [HAVE_TERMIO] (init_baud_rate): Don't use tcgetattr
        unless HAVE_TCATTR is defined.  Only very rarely do termio systems
        have the tc{get,set}attr macros.

        * window.c (coordinates_in_window): Do not assume that all
        one-line windows are the minibuffer, or that all minibuffers are
        one line high.  Use MINI_WINDOW_P.

        * systerm.h: Renamed to systty.h, to be more consistent with
        everything else in Unix.
        * dispnew.c, emacs.c, keyboard.c, process.c, sysdep.c: #include
        directive changed.
        * ymakefile: References to systerm.h changed.

        * s/usg5-3.h: Merged changes from 18.58:
        (HAVE_SYSV_SIGPAUSE): Defined.
        (BROKEN_TIOCGETC): Defined.

1992-08-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * process.c (WCOREDUMP): Define only if not defined.
        (create_process) [HAVE_SETSID]: Use TIOCSCTTY if exists.
        
1992-08-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * fileio.c (Fdo_auto_save): Call Fsleep_for with the appropriate
        number of arguments.
        * fns.c (Fyes_or_no_p): Same.

        * dispnew.c (update_frame): Change the way we handle
        cursor_in_echo_area.  Firstly, ignore this if the frame we're
        updating doesn't have a minibuffer.  Secondly, don't handle the
        selected frame specially.  Thirdly, don't assume that the
        minibuffer is only one line high.  If cursor_in_echo_area < 0, put
        the cursor in the upper-left corner; if cursor_in_echo_area > 0,
        put it on the lowest non-empty line in the minibuffer window, or
        on the top line.

        * dispnew.c (direct_output_for_insert): Fail if
        cursor_in_echo_area is set; we don't want to do the typing there.
        (direct_output_for_insert): Same.

1992-08-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (x_make_frame_invisible): Use XWithdrawWindow when
        available [HAVE_X11R4]; send the UnmapNotify event when
        appropriate [HAVE_X11]; just unmap the window if that's all that's
        needed [not HAVE_X11].

        * xterm.c (x_set_text_property): Removed; it's only called from
        one place.  Who wants *another* layer of indirection?
        * xfns.c (x_set_name): Use XSetWM{Name,IconName} when available
        [HAVE_X11R4], or XSetIconName and XStoreName otherwise.

        * xterm.h (FRAME_X_WINDOW): New macro, for readability.
        * xterm.c, xfns.c, xselect.c: Use it.

        * emacs.c (Fkill_emacs): Doc fix.
        (syms_of_emacs): Doc fix for Vkill_emacs_hook.

        * xterm.c (x_death_handler): Renamed to x_connection_closed.
        (x_term_init): Use x_connection_closed as the SIGPIPE handler.

        * xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
        x_error_handler): Removed; you can't catch X errors this way,
        since you can't perform X operations from within an X error
        handler, and even though we call error, we're still within an X
        error handler.
        (x_error_quitter, x_error_catcher): New functions, for panicking
        on and catching X protocol errors.
        (x_caught_error_message): Buffer for caught X errors.
        (x_catch_errors, x_check_errors, x_uncatch_errors): New functions
        for catching errors.
        (x_term_init): Set the error handler to x_error_quitter, rather
        than x_error_handler.
        * xfns.c (x_set_mouse_color): Use x_catch_errors, x_check_errors,
        and x_uncatch errors to avoid crashing if the user selects an
        odd cursor.

        * xterm.c (x_proto_requests): Removed; it's not important.
        
        * xterm.c (events): Array removed; it's not used.

        * xfns.c (select_visual): Use XVisualIDFromVisual when available
        [HAVE_X11R4].
        
        * xrdb.c (get_user_db): Use XResourceManagerString when available
        [HAVE_X11R4].

        * window.c (change_window_height): If the size of the window will
        shrink below the minimum, this code would only try to delete it if
        it had a parent.  Well, even if the window doesn't have a parent,
        you want Fdelete_window to signal an error, since you're trying to
        resize one of the undeleteable windows into nothingness.  So call
        Fdelete_window even if the window doesn't have a parent.

        * window.c (MINSIZE): Add kludge so that the minibuffer is always
        allowed to shrink to one line in height.
        (MINSIZE, CURBEG, CURSIZE): Change these so that their argument
        are always Lisp_Objects, not struct window *'s.
        (change_window_height): Changed accordingly.

1992-08-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * frame.h (struct frame): New member - explicit_name.
        * frame.c (make_frame): Clear it.
        * xfns.c (x_set_name): Take new argument EXPLICIT, instead of
        OLDVAL.
        (x_explicitly_set_name, x_implicitly_set_name): New functions.
        (x_frame_parms): Use x_explicitly_set_name here.
        (x_window): Use x_implicitly_set_name here.
        * xdisp.c (display_mode_line): Use x_implicitly_set_name here.

        * xterm.c (x_wm_hints): Variable deleted.  This has to be
        per-screen.  Duh.
        * xterm.h (struct x_display): New member: wm_hints.
        * xterm.c (x_wm_set_window_state, x_wm_set_icon_pixmap,
        x_wm_set_icon_position): Use F->wm_hints, rather than x_wm_hints.
        (x_term_init): Don't initialize x_wm_hints here.
        * xfns.c (Fx_create_frame): Instead, initialize f->x_wm_hints
        here.

        * xterm.c (x_set_text_property): Properly balance the BLOCK_INPUTs
        and UNBLOCK_INPUTs.  And remember that VALUE is the string we want
        to set the name to, not PROPERTY.

1992-08-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * frame.c (make_minibuffer_frame): Don't set this to auto-raise by
        default.  It's annoying.

        * frame.c (make_minibuffer_frame): Set the prev field of the
        minibuffer window on a minibuffer-only frame to Qnil, rather than
        having it point to itself.  This confuses code (Fprevious_window
        and change_window_height, for example), and is only an attempt to
        support a convention that can't really be used in Emacs 19 anymore.
        * window.h: Document the fact that we can no longer assume that
        the minibuffer's previous window is the root window, since a
        minibuffer window in a minibuffer-only frame has a prev field of
        nil.
        * frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this by
        reference to the_only_frame.root_window, rather than by assuming
        that minibuf_window->prev is the root window.  While this is true
        in the non-multi-frame case, we want to discourage this assumption
        in code.
        * dispnew.c [not MULTI_FRAME] (Fredraw_display): Use
        FRAME_ROOT_WINDOW instead of minibuf_window->prev.
        * xdisp.c (redisplay, init_xdisp): Same.
        * window.c (Fset_window_configuration): Removed #if 0'd code which
        assumes that minibuf_window is on the same frame as the window
        configuration.  Removed special case for windows whose prevs
        point to themselves.

        * window.c (Fset_window_configuration): Rename the argument from
        ARG to CONFIGURATION, so it matches the docstring.  The
        make-docfile program cares.

        * window.c [MULTI_FRAME] (syms_of_window): Don't staticpro
        minibuf_window; the frame list will take care of it.

        * xterm.h (HAVE_X11R4): Since we can autodetect this, and can
        write code more likely to be future-compatible, define this when
        appropriate.
        * xterm.c (x_set_text_property): Define this appropriately for
        X11R3 and X11R4.

        * xterm.c (x_set_text_property): Make this take a Lisp_Object
        string as an argument, rather than a pointer and a length.
        * xfns.c (x_set_name): Caller changed.

        * xfns.c (x_get_arg): Accept a new type - symbol.  If we've
        retrieved a string from the xrdb database and the user wants a
        symbol, intern it.
        (Fx_create_frame): Use the symbol type here.

        * xfns.c (x_figure_window_size, x_icon, Fx_create_frame): Use
        values from enum resource_types for the last arg to x_get_arg,
        instead of passing numbers.

        * xfns.c (Fx_create_frame): When setting up the scroll bars, use
        the type parameter to x_default_parameter, rather than prefixing
        the resource name with a question mark.

        * xfns.c [not HAVE_X11] (Fx_create_frame): The resource which
        determines whether or not to use a bitmapped icon is called
        "IconType", not "BitmapIcon".  Update this.

1992-08-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c: Doc fixes.

        More SYSV portability changes from Eric Raymond:

        * xterm.c [USG5]: Don't include <sys/types.h>.

        * xterm.c (x_make_frame_invisible): Instead of calling XWithdraw
        window, which isn't widely available, write out what it does,
        since that's not much.
        (x_iconify_frame): Explicitly perform both the X11R3 and X11R4
        methods for iconification; don't use XIconifyWindow, since that's
        not present in R3.
        
        * xterm.c (x_wm_set_size_hint): Don't bother setting the
        base_width and base_height members; their function is performed
        just as well by the min_width and min_height members, and if we
        use XSetNormalHints instead of XSetWMNormalHints, we can be
        compatible with R3.

        * xterm.c (x_error_handler): There is no way to invoke the default
        error handler which works on all versions of X11, so don't bother;
        call XGetErrorText and print the message ourselves.

        * xterm.c (x_term_init): Don't use MAXHOSTNAMELEN; this isn't
        defined on all systems.  Since we only use that as an initial
        guess anyway, it's not very important.

1992-08-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * abbrev.c (Fexpand_abbrev): If pre-expand hook changes the buffer,
        assume that means we "did an expansion".

        * cmds.c (internal_self_insert): Ignore value of Fexpand_abbrev;
        instead, check whether buf is modified when it returns.

1992-08-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        Applied SYSV portability changes from Eric Raymond:

        * xrdb.c [USG5]: Define SYSV, and then include <unistd.h>.
        Apparently, Xlib.h include string.h if SYSV is defined, and
        strings.h if not.
        Don't include <sys/types.h>; just declare getuid to return an
        int.  Big deal.
        (MAXPATHLEN): If this is not defined by the system's include
        files, give it a value of 256.
        (get_user_db): Fetch the defaults directly from the display
        structure, rather than using XResourceManagerString; that
        function doesn't exist in the older versions of X.

        * xterm.c (x_set_text_property): New function.
        * xfns.c (x_set_name): Use it instead of XSetWMName and
        XSetWMIconName.

        * xfns.c (select_visual): Fetch the visual id directly from v;
        don't call XVisualIDFromVisual, since that function is not
        available in earlier versions of X.

        * term.c (term_get_fkeys): Some systems define `static' to be the
        empty string, which means that you can't have constant
        initialized arrays inside a function.  So move the `keys' array
        outside of the function.
        * xdisp.c (decode_mode_spec): Same deal, with lots_of_dashes.
        * xfns.c (x_make_gc): Same deal, regarding cursor_bits.

        * term.c (keys): Include definitions for "K2" (the center key on
        an IBM keypad), "F1" (F11), and "F2" (F12).  Handle "k0" and "k;"
        specially; see the code for details.

        * term.c (clear_end_of_line): Remember that on some systems,
        "static" gets defined to be the null string, so we can't declare
        an array to be static and then initialize it.  Since the array in
        question (buf) is only one element long, just make it a scalar
        rather than an array; it can then be initialized, even if it's
        not static.

        * systime.h [not HAVE_TIMEVAL] (EMACS_USECS, EMACS_SET_USECS):
        Don't forget to define dummy versions of these.

        * systime.h [USE_UTIME]: time_t is a typedef, not a struct.
        Don't prefix it with `struct'.

        * systerm.h (EMACS_SET_TTY_PGRP): When there doesn't seem to be
        any way to do this, don't forget to give it a dummy definition.

        * sysdep.c (select): There's no need to cast the return value of
        signal anymore, since we have the SIGTYPE macro defined.

        * sysdep.c (read_input_waiting): When scanning for quit
        characters, use the value of quit_char, rather than assuming that
        C-g is the quit character.  And don't forget to declare i.

        * sysdep.c [USG5]: Don't include fcntl.h.

        * s/usg5-3.h: Eric Raymond writes:
        Define HAVE_SELECT and BSTRINGS only if HAVE_X_WINDOWS is on,
        because that means we'll be linking in the shared libraries
        containing the BSD emulations.  Teach the file about the shared
        libraries necessary to link X programs, because AT&T doesn't
        supply static libraries for X.  Also, fix the incorrect assertion
        that -lg cannot be used with SVr3.  Finally, force USE_UTIMES and
        BROKEN_TIOCGWINSZ.  (Note for the future; there may be a
        utimes(2)) emulation lurking in the X shared libraries.)

        * s/usg5-4.h (USE_UTIME): Remove this definition; the C library
        still doesn't have utimes.

        * ralloc.c (get_bloc): When initializing new_bloc->variable, cast
        NIL to (POINTER *).
        (malloc_init): Give warning if sbrk returns zero.  Wonder what
        that's supposed to mean.

        * process.c (process_send_signal): Don't send SIGTSTP if the
        system doesn't have that facility.

        * process.c: [USG5] Don't include <fcntl.h>.
        [USG] Don't bother including <termios.h>, <termio.h>, or
        <fcntl.h>; systerm.h takes care of all that.
        Remove the "mis;tak-+;;" line from the code; apparently this
        section of code does get used.

        * minibuf.c (Fread_from_minibuffer): Put this function's doc
        string into a comment; it's too long for the PCC preprocessor.
        Rah.
        (Fcompleting_read): Same deal.

        * keyboard.c (init_keyboard): Changed "#endif SIGIO" to
        "#endif /* SIGIO */"
        * mocklisp.c (Fml_substr): Same sort of thing.
        * process.c (wait_reading_process_input): Same.

        * floatfns.c (Fexpm1, Flog1p): Function removed; it's not widely
        available, and hardly vital.
        (syms_of_floatfns): Adjusted appropriately.

        * floatfns.c (Flog): Accept optional second arg, being the base
        for the logarithm.
        [USG] (Flogb): Define this in terms of Flog.

        * data.c [USG] (Frem): Call fmod, rather than drem.  Rah.

        * emacs.c [USG5]: Don't #include <fcntl.h> for these systems.

        * alloc.c (Fmake_marker): Removed the test for being called from a
        signal handler.  The original bug is probably gone, the test
        wasn't written portably, and it should probably go somewhere else
        anyway - say, funcall or eval.

        End of changes from Eric Raymond.

        * xfns.c (Fx_create_frame): Make the default for the icon-type
        parameter nil, not t.  It seems to cause problems with some X
        servers.

        * lisp.h (DEFVAR_PER_BUFFER): Add new argument, TYPE, to help
        check the types of buffer-local variable slots.
        * buffer.c (syms_of_buffer): Call DEFVAR_PER_BUFFER with the new
        TYPE argument.
        * abbrev.c (syms_of_abbrev): Same.
        * buffer.c (buffer_local_types): New variable.
        (buffer_slot_type_mismatch): New function.
        * buffer.h (buffer_local_types): New extern declaration.
        * data.c (store_symval_forwarding): When storing through a
        Lisp_Buffer_Objfwd, check if the slot requires a particular type,
        and report an error if the types clash.
        * lread.c (defvar_per_buffer): Support new TYPE argument, by
        setting the appropriate slot in buffer_local_types.

1992-08-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * window.c (window_loop): This used to keep track of the first
        window processed and wait until we came back around to it.  Sadly,
        this doesn't work if that window gets deleted.  So instead, use
        Fprevious_window to find the last window to process, and loop
        until we've done that one.

        * window.c [not MULTI_FRAME] (init_window_once): Don't forget to
        set the `mini_p' flag on the new minibuffer window to t.

        * window.c (Fwindow_at): Don't check the type of the frame
        argument.

        * window.c [not MULTI_FRAME] (window_loop): Set frame to zero,
        instead of trying to decode it.

        * frame.h [not MULTI_FRAME] (the_only_frame): Put a comment above
        this indicating that it's not GCPRO'd.  Put parens around some of
        the FRAME_* macros' definitions.
        [not MULTI_SCREEN] (Fselected_frame): New function.

        * frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this in
        terms of minibuf_window, rather than by reference to
        the_only_frame.
        * window.c (init_window_once): Initialize minibuf_window before
        FRAME_ROOT_WINDOW, so the latter actually points to something.

        * keyboard.c (Fexecute_mouse_event): dyked-out function deleted.
        We're not going to use this mouse interface.
        (Vmouse_window, Vmouse_event, Vmouse_event_function,
        Vmouse_left_hook, Vmap_frame_hook, Vunmap_frame_hook,
        Vmouse_motion_handler): Variables deleted; they were to be used by
        Fexecute_mouse_event.
        (syms_of_keyboard): Same.
        (command_loop_1): Remove dyked-out code to support
        Fexecute_mouse_event.
        (read_char): Same.

        * keyboard.c (Vlast_event_frame): Don't define this window if
        MULTI_FRAME is not #defined.
        (syms_of_keyboard): Same.
        (kbd_buffer_store_event): Don't try to work with Vlast_event_frame
        if MULTI_FRAME is not #defined.
        (kbd_buffer_get_event): Same.

        * keyboard.c (Fdiscard_input): Removed dyked-out code from when
        unread_command_char's quiescent value was -1, not nil.

        * frame.c (make_frame): Stop passing zero to make_window; it's not
        expecting any arguments.

1992-08-12  Jim Blandy  (jimb@albert.gnu.ai.mit.edu)

        * unexsunos4.c: Deleted "$Log" header in comments at top of file;
        this was beginning to grow RCS hair, which we don't want.
        * xmenu.c: Same deal.

1992-08-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * fileio.c (Fread_filename): Don't add one here.
        * minibuf.c (Fcompleting_read): Instead, stop subtracting one
        here, so this function lives up to its doc string, which I think
        specifies an okay way to work.

        * doc.c (Vdata_directory): Removed; this is declared in callproc.c.
        (syms_of_doc): Initialization removed.

        * xfns.c (x_get_arg): Return Qunbound for an unspecified
        resource, not nil.  That way, we can tell the difference between a
        false resource and an unspecified resource.
        (x_default_error): Use DEFLT if x_get_arg returns Qunbound, not Qnil.
        (x_figure_window_size, x_icon, Fx_create_frame): Deal with
        Qunbound and Qnil properly.

        * xfns.c (Fx_create_frame): Pass the correct number of arguments
        to x_set_font.

        * xfns.c [not HAVE_X11] (Fx_create_frame): Delete section that's
        only included if we *do* have X11.  Blind patching.

        * xfns.c (x_icon): Rewritten to call x_wm_set_icon_position and
        x_wm_set_window_state instead of calling XSetWMHints directly.
        * xterm.c (x_wm_hints): New variable.
        (x_wm_set_window_state, x_wm_set_icon_pixmap,
        x_wm_set_icon_position): Use x_wm_hints.
        (x_term_init): Set the `input' field of x_wm_hints, and its flag.

        * xterm.c (x_text_icon): Call x_wm_set_icon_pixmap with a pixmap
        of zero, to clear the pixmap.
        (x_wm_set_icon_pixmap): Accept this protocol; if pixmap is zero,
        specify no pixmap for the icon.

        * xfns.c (x_default_parameter): Don't call store_frame_param here;
        it's already taken care of by x_set_frame_parameters.

        * xfns.c (Fx_create_frame): Check for the `icon-type',
        `auto-raise', and `auto-lower' parameters. Have `icon-type'
        default to t, indicating that we want the nifty gnu in our icons.
        (Qauto_lower): New symbol.

        * xfns.c (x_set_icon_type): UNBLOCK_INPUT before reporting the
        error, not after.  error doesn't return, sklitch-brain.

        * xterm.c (x_set_window_size): Call check_frame_size to make sure
        that the requested dimensions are within acceptable limits.
        Store the new size information in the frame structure.

        * xfns.c (x_set_frame_parameters): Properly recognize changes to
        the height of the frame.  Recognize changes of the frame's
        position.

        * xfns.c (x_set_frame_parameters): Iterate over ALIST while the
        current element is cons, not while it's non-nil.
        (syms_of_xfns): Call init_x_parm_symbols after interning all the
        other atoms; init_x_parm_symbols expects Qx_frame_parameter to be
        initialized.

1992-08-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xfns.c (Qbackground_color, Qborder_color,  Qborder_width,
        Qcursor_color,  Qfont,  Qforeground_color,  Qgeometry,
        Qhorizontal_scroll_bar,  Qicon_left,  Qicon_top,  Qiconic_startup,
        Qinternal_border_width,  Qleft,  Qmouse_color,  Qparent_id,
        Qsuppress_icon,  Qsuppress_initial_map,  Qtop,  Qundefined_color,
        Qvertical_scroll_bar,  Qwindow_id,  Qx_frame_parameter): New
        symbols, with lisp code to rebuild syms_of_xfns.
        (syms_of_xfns): Initialize and staticpro them.
        (Qheight, Qminibuffer, Qname, Qnone, Qonly, Qwidth,
        Qunsplittable): Add extern declaration for these.
        (x_init_parm_symbols): Don't initialize Qx_frame_parameter here;
        it's done in syms_of_xfns.
        (x_default_parameter): Change the argument char *PROPNAME into a
        Lisp_Object PROP; let the caller take care of interning the atom.
        (Fx_geometry, x_figure_window_size, x_icon, Fx_create_frame): Use
        the new Q... variables, instead of interning things.

        * frame.c (Qheight, Qicon, Qmodeline, Qname, Qnone, Qonly,
        Qunsplittable, Qwidth, Qx): New symbol, with lisp code to rebuild
        syms_of_frame.
        (syms_of_xfns): Initialize and staticpro them.
        (Fframep, Fframe_visible_p, Fframe_parameters):  Use
        the new Q... variables, instead of interning things.
        (store_in_alist): Change the argument char *PROPNAME into a
        Lisp_Object PROP; let the caller take care of interning the atom.

        * frame.c (Fframe_visible_p): Doc fix.

        * frame.c (Fframe_parameters): When figuring the `minibuffer'
        parameter, if FRAME doesn't have a minibuffer, return `none', not
        nil.  If it does have a minibuffer with other windows, return the
        window.

        * frame.c (Fmodify_frame_parameters): Don't write out the loop for
        processing X frame parameters here; do it in the x specific code.
        Call the function which deals with this stuff
        x_set_frame_parameters, not x_set_frame_parameter.
        * xfns.c (x_set_frame_param): Replaced by x_set_frame_parameters.
        (x_set_frame_parameters): Process the alist of parameters here.
        Notice `width', `height', `top', and `left' parameters.
        Hold off changing the frame size and position until the end, so we
        can do both parameters at once when they are both specified.
        (x_default_parameter): Call x_set_frame_parameters, not
        x_set_frame_param.

        * frame.c (Fmake_frame_visible, Fmake_frame_invisible,
        Ficonify_frame, Fframe_parameters, Fmodify_frame_parameters,
        Fset_frame_height, Fset_frame_width, Fset_frame_size,
        Fset_frame_position): Place clauses controlled by FRAME_X_P inside
        `#ifdef HAVE_X_WINDOWS ... #endif' clauses.

        * frame.c (Fset_frame_position): Doc fix.

        * dispnew.c (Fredraw_frame): Call clear_frame_records before
        calling update_end, so that x_display_box_cursor can rely on the
        contents of f->current_glyphs.

        * xfns.c (x_figure_window_size): Indicate that this function
        returns an int, rather than just leaving it unstated.

        * xterm.c (x_wm_set_size_hint): Don't try to set the base_height
        and base_width elements of size_hints if PBaseSize is not
        #defined.  Set the minimum frame size according to the information
        returned by check_frame_size.

        * window.h (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
        removed.
        (check_frame_size): New extern declaration.
        * window.c (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
        defined here now.
        (check_frame_size): New function.
        * dispnew.c (change_frame_size): Call check_frame_size here,
        rather than writing out its code.  Don't declare newheight and
        newwidth to be register variables, since we take their address.

        * bytecode.c (Fbyte_code): When metering the Bcall opcodes, make
        sure the count on the symbol's `byte-code-meter' property does not
        overflow.

        * bytecode.c (syms_of_bytecode): Add a docstring for
        byte-metering-on.

1992-08-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * dispnew.c (in_display): Variable deleted; it's only ever used as
        an unofficial parameter to change_frame_size.
        (change_frame_size): New argument, DELAY, which when non-zero
        indicates to delay the size change until later.  This should be
        passed as one from signal handlers.
        (window_change_signal): Call change_frame_size with a DELAY of 1.
        (do_pending_window_change): Call change_frame_size with DELAY of 0.
        * frame.c [MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
        Fset_frame_size): Same.
        [not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
        Fset_frame_size, Fset_screen_height, Fset_screen_width): Same.
        * keyboard.c (Fsuspend_emacs): Call change_frame_size with the
        proper arguments - the height and width are the second and third
        arguments, not the first and second.  Pass 0 for DELAY.
        * xfns.c (Fx_create_frame): Call change_frame_size with a DELAY of 0.
        * xterm.c (XTread_socket, x_do_pending_expose): Call
        change_frame_size with a DELAY of 1.
        
        * xterm.c (in_display): Deleted this; it's never used in xterm.c,
        and there is another variable by the same name in dispnew.c.

        * frame.c [not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
        Fset_frame_size, Fframe_height, Fframe_width): New functions, for
        use when Emacs is not compiled with multiple screens.
        [not MULTI_SCREEN] (Fset_screen_height, Fset_screen_width):
        Functions added for backward compatibility with Emacs 18.  These
        would be just aliases, except that the version 18 functions don't
        take a FRAME argument.
        [not MULTI_SCREEN] (syms_of_frame): New function, to defsubr the
        above and add screen-height and screen-width as aliases for
        Fframe_height and Fframe_width.
        * emacs.c (main): Call syms_of_frame unconditionally.  When
        MULTI_FRAME is not defined, it still provides the Fframe_width,
        Fframe_height, Fset_frame_width, and Fset_frame_height functions.

        * frame.c (Fset_frame_width): Change the size of FRAME, not of
        selected_frame.

        * frame.c (Fset_frame_width, Fset_frame_height): Declare the
        `frame' argument to be a Lisp_Object.  It used to be undeclared.

1992-08-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * dispnew.c, frame.c, frame.h, keyboard.c, scroll.c, term.c,
        window.c, xdisp.c, xfns.c xterm.c (FRAME_IS_TERMCAP, FRAME_IS_X,
        FRAME_HAS_MINIBUF): Renamed these to FRAME_TERMCAP_P, FRAME_X_P,
        and FRAME_HAS_MINIBUF_P, for consistency with the rest of the
        frame macros.

        * window.h (MIN_SAFE_WINDOW_WIDTH, MIN_SAFE_WINDOW_HEIGHT): New
        macros.
        * window.c (check_min_window_sizes): New function.
        (set_window_height): Call it.
        (Fsplit_window, change_window_height): Call it, instead of writing
        out its code.
        * dispnew.c (change_frame_size): If newlength or newwidth are too
        small (according to the value of MIN_SAFE_WINDOW_{WIDTH,HEIGHT}),
        force them larger.  This isn't really right, but it's better than
        crashing.

        * editfns.c (Fcurrent_time_zone): Doc fix.

1992-08-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * editfns.c (Fcurrent_time_zone): Don't forget to include code to
        signal an error when EMACS_CURRENT_TIME_ZONE is not defined.

1992-08-06  Joseph Arceneaux (jla@gnu.ai.mit.edu)

        * doc.c (Vdata_directory): Declared.
        (syms_of_doc): Initialized.

        * fileio.c (Fread_filename): Add 1 to the offset position for the
        cursor when reading file names.

1992-08-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * systime.h (EMACS_CURRENT_TIME_ZONE): New macro.
        * editfns.c (Fcurrent_time_zone): New function.
        (syms_of_editfns): defsubr it.

        * keyboard.c (read_key_sequence): Clear the eighth bit of the
        character from the key sequence, NOT the index of the character IN
        the key sequence.  How many tries will it take to get it right?

1992-08-04  Roland McGrath (roland@churchy.gnu.ai.mit.edu)

        * eval.c (syms_of_eval): Doc fix for debug-on-quit.

1992-08-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callproc.c (Fcall_process): Doc fix.  Used to claim that
        Fcall_process doesn't wait when BUFFER was nil.  It does.

1992-07-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * keyboard.c (read_key_sequence): Scan for function keys when t >=
        mock_input, not when t > mock_input.  We do want to scan for
        function keys when t == mock_input.

        * keyboard.c (read_key_sequence): Don't increment fkey_end when
        testing to see if keybuf[fkey_end] is a meta-character.

1992-07-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * Makefile.in (TAGS): Generate tags for files in ../external-lisp
        too.

1992-07-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * eval.c (find_handler_clause): For quit, don't check Vdebug_on_error.
        (wants_debugger): Rewrite so it cannot get an error.

        * callint.c (Fcall_interactively): Handle enable-recursive-minibuffers
        property on the command, by enabling recursive minibuffers.
        (syms_of_callint): Set Qenable_recursive_minibuffers.

1992-07-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * frame.c (Fmake_frame_visible, Fmake_frame_invisible,
        Ficonify_frame): Make the first argument optional, defaulting to
        selected_frame.
        (Ficonify_frame, Fmake_frame_invisible): Add interactive specs, so
        we can bind these directly to C-z.

1992-07-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c (Fread_file_name): Use new calling convention for
        Fcompleting_read, with history as Qfile_name_history.
        (syms_of_fileio): Set Qfile_name_history; set the var to nil.
        Do staticpro for the recently created Q* vars.  

        * minibuf.c (read_minibuf): Two additional args histvar and histpos.
        All calls changed.
        (Fcompleting_read): Last arg is now HIST--(HISTVAR . HISTPOS).
        Arg INIT can now be (INITIAL-STRING . INITIAL-POSITION).
        Pass BACKUP_N arg to read_minibuf properly as Lisp object.      
        (Fread_from_minibuffer): Likewise.
        (syms_of_minibuf): Set Qminibuffer_history and staticpro it.

        * eval.c (Ffuncall, Feval): Support subrs with 7 args.

        * fns.c (Fyes_or_no_p): Use Fread_string, not read_minibuf.
        * callint.c (Fcall_interactively): For 'S', use Fread_no_blanks_input
        rather than read_minibuf.       

1992-07-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
        
        * minibuf.c (Vminibuffer_history_variable): New variable.
        (syms_of_minibuf): Define variable minibuffer-history-variable. 
        (read_minibuf): Push the string on specified history list.
        
1992-07-23  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Makefile.in (doall, doxemacs, dotemacs): Put quotes around CC=${CC}.
        Don't include $(MAKEOVERRIDES); that is always implicit.

1992-07-22  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * keyboard.c (read_key_sequence): If we have read a
        meta-character, prefix it with meta_prefix_char before looking it
        up in the function key keymap.

        * lread.c (Fread_char_exclusive): Code this with a do-while loop,
        not a while loop with its body repeated.

        * lread.c (Fread_event): Don't make this function's definition
        conditional on X-windows.  It ought to be there no matter how
        Emacs was built.
        (syms_of_lread): Don't make its defsubr conditional either.

        * lread.c (Fread_char): Doc fix.

        * fileio.c (find_file_handler): It's called
        Vfile_name_handler_alist, not Vfile_handler_alist.
        (Fwrite_region): Declare the variable named `handler'.
        (Fverify_visited_file_modtime): Use `b->filename', not `filename'.
        (Fset_visited_file_modtime): Declare the variable named `handler'.
        * dired.c (Fdirectory_files, Ffile_name_completion): Use
        `dirname', not `filename'.
        (Qfile_attributes): New variable.
        (syms_of_dired): Initialize it.

        * xselect.c (Fx_own_selection): If we're trying to set
        cut-buffer0, and the value is too large for the X server (as
        indicated by the max_request_size member of the X Display), just
        set the buffer to the empty string, and return nil.

1992-07-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * search.c (fast_string_match): New function.
        * fileio.c (find_file_handler): New function.
        (Fcopy_file, Fmake_directory, Fdelete_directory, Fdelete_file):
        (Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
        (Ffile_exists_p, Ffile_executable_p, Ffile_readable_p, Ffile_symlink_p)
        (Ffile_writable_p, Ffile_directory_p, Ffile_accessible_directory_p):
        (Ffile_modes, Fset_file_modes, Ffile_newer_than_file_p):
        (Fwrite_region, Fverify_visited_file_modtime):
        Use find_file_handler; call the handler and return.
        (Finsert_file_contents): Use find_file_handler;
        cannot just return after the handler, but must handle VISIT.
        (syms_of_fileio): Set up Qcopy_file, etc.       
        * dired.c (Fdirectory_files, Ffile_name_completion):
        (Ffile_name_all_completions, Ffile_attributes):
        Use find_file_handler; call the handler.
        (syms_of_dired): Set Qfile_attributes, etc.

1992-07-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xselect.c (Fx_own_selection): Initialize val to nil, so that if
        we don't get the selection, we don't return garbage.  When setting
        cut-buffer0, set val to the string pasted.

        * xfns.c (x_set_name): If ARG is nil, set the frame's name to the
        current x_id_name.
        * xdisp.c (display_mode_line): If we should set the frame's name,
        but there is only one frame currently active, call x_set_name with
        nil as the name; this will display samething generically
        appropriate.

1992-07-20  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
        
        * lread.c (isfloat_string): Recognize floats without a leading
        integer part, noting that "e5" is a symbol, not a floating point
        number.
        
        * xdisp.c (message, message1): When displaying a message, don't
        make the minibuf frame visible unless the selected frame is also
        visible.  This means that frames won't pop up unless the user is
        actually interacting with Emacs.

        * xdisp.c (display_mode_line): If Emacs is currently supporting
        only one screen, don't change the title of the screen to the name
        of the current buffer; this is only annoying in this case.  We
        should probably think more carefully about how screens should be
        named.

1992-07-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
        
        * process.c (allocate_pty): Handle PTY_OPEN.    
        Delete system-specific alternatives to PTY_NAME_SPRINTF
        and PTY_TTY_NAME_SPRINTF.       
        
1992-07-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
        
        * callint.c (Fprefix_numeric_value): Fix typo: test raw, not val.
        
1992-07-17  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xfns.c (x_window): x_set_name normally ignores requests to set
        the name if the requested name is the same as the current name.
        This is the one place where that assumption isn't correct; f->name
        is set, but the X server hasn't been told.  So fake it out.

        * emacs.c [sun] (main): On suns, localtime caches the value of the
        time zone rather than looking it up every time.  This means that
        the dumped Emacs doesn't check the value of the TZ environment
        variable.  Call tzset before entering the editing loop to check
        the new TZ value.

1992-07-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * dired.c (Fdirectory_files): Don't forget to pass the REGP
        argument to compile_pattern.
        * search.c (compile_pattern): If REGP is zero, don't call
        re_set_registers; nobody cares.

        * fileio.c (auto_save_error): Pass the correct number of arguments
        to Fsleep_for.

        * lread.c: Include <ctype.h> at the top of the file, instead of
        just before isfloat_string; read0 wants to use it too.

        * process.c (Fdelete_process, Fprocess_status, Fprocess_send_region,
        Fprocess_send_string, Fprocess_send_eof, Finterrupt_process): Doc
        fixes.
        
        * process.c (Fprocess_status): Use get_process to find the process
        denoted by the PROC argument, not Fget_process.

1992-07-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xdisp.c: Doc fix.

1992-07-14  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * window.c (syms_of_window): Doc fix for pop-up-frames.

        * frame.c (Fframe_parameters): Note that if FRAME is omitted, it
        defaults to the selected frame.

        * frame.c (Fframe_height, Fframe_width): Blocked out these
        functions; they have no C callers, and can be written nicely in
        lisp.
        
        * frame.c (Fframe_pixel_size): Function removed; there aren't
        enough other functions available to make this useful.  We need
        functions describing the size of the characters of a font.

        * xterm.h, xterm.c, xselect.c, xmenu.c, xfns.c, xdisp.c, window.h,
        window.c, termopts.h, termhooks.h, termchar.h, term.c sysdep.c,
        scroll.c, screen.c, screen.h, process.c, print.c, minibuf.c,
        lisp.h keyboard.c, indent.c, fns.c, emacs.c, dispnew.c,
        dispextern.h, cm.h, alloc.c, config.h.in: Screens are now called
        frames, to avoid even more confusion with X terminology than
        Emacs's "windows" already cause.  All macros, functions, and
        variables renamed; all uses changed.
        * screen.c, screen.h: Renamed to frame.c and frame.h.  All
        #includers changed.
        * ymakefile: Adjusted appropriately.
        * buffer.c: Doc fixes.

        * xfns.c (Fx_store_cut_buffer): Reversed sense of test for non-X
        screen.

        * window.c (Frecenter): Doc fix; this function places point in the
        middle of the current window, not the current screen.

        * window.c (temp_output_buffer_show): Use WINDOW_SCREEN macro
        instead of accessing the member directly.

1992-07-13  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * print.c (print): Changed code which prints screen objects to use
        the SCREEN_LIVE_P macro instead of testing the screen structure
        directly.

        * alloc.c (undo_threshold, undo_high_threshold): Variables renamed
        to undo_limit and undo_strong_limit.
        (Fgarbage_collect): Uses changed.
        (syms_of_alloc): DEFVARs and docstrings changed.
        * undo.c (truncate_undo_list): Comment adjusted.

        * lread.c (read0): Allow floating-point numbers to begin with a
        period.  `(0 .5)' denotes a list of two numbers, not a dotted pair.

1992-07-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fns.c, callproc.c: Doc fix.

1992-07-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * bytecode.c (Bsymbol_function, Bfset): Removed comments saying
        that these are no longer generated.  Jamie Zawinski's byte
        compiler does generate them, and he's actually collected
        statistics on how often these functions are called.

1992-07-09  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * screen.c (store_screen_param): Clarify error message.

        * xterm.c (x_make_screen_visible): Undo the change made on June
        30; that is not the right solution.  Apparently there are three
        states a window may be in: normal, iconified, and invisible.

1992-07-08  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * eval.c (Fmacroexpand): Code cleaned up; there's no need to
        handle forms like ((macro lambda ...) ...) specially.

        * fileio.c (Finsert_file_contents): Signal an error if we're asked
        to read from a named pipe.

1992-07-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * m/*.h (SIGN_EXTEND_CHAR): Removed these definitions.  The only
        place they were used is in regex.c, and nowadays that has its own
        definition, which works for any machine.  The definitions in the
        machine description files usually didn't work if given an unsigned
        character as an argument, anyway.

1992-07-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * buffer.c: Doc fix.

1992-07-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * minibuf.c (Fdisplay_completion_list): Declared new variables
        used in rms' previous change.

1992-07-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * minibuf.c (Fdisplay_completion_list): Handle non-buffer stream.

1992-07-01  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * window.c (Fdisplay_buffer): Add interactive spec.

1992-06-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * mem_limits.h: EXCEEDS_ELISP_PTR declared here.
        * ralloc.c: No longer declared here.
        * vm-limit.c: Nor here.  Also, include "lisp.h" before
        "mem_limits.h" and additionally include "config.h".

1992-06-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (x_make_screen_visible): Don't de-iconify the window;
        iconification is orthogonal to visibility.

        * emacs.c (syms_of_emacs): Change docstring for `kill-emacs-hook'
        to describe it as a hook, not as a single function.

1992-06-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * minibuf.c (Fread_no_blanks_input): Corrected maximum number of
        arguments from one to two.

        * emacs.c (Vkill_emacs_hook): Declare this here; it should have a
        docstring, so we might as well DEFVAR it.
        (syms_of_emacs): initialize it, and DEFVAR_LISP it with an
        appropriate docstring.

1992-06-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * lread.c (Feval_buffer): Make the DEFUN match the C argument
        list; this takes two optional arguments, not just one.

        * lisp.h (Lisp_Buffer_Local_Value): Comments neatened.

        * data.c (Fset): Fixed conditional which tests whether the cache
        is invalid.  It used to be pretty munged, and would always declare
        the cache invalid for Lisp_Buffer_Local_Value variables.  Now it
        declares the cache invalid if the buffer is wrong (obviously), of 

1992-06-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * data.c (Fset): Comments reformatted for readability.

        * xterm.c (last_mouse_movement_time): New variable.
        (note_mouse_position): Set it.
        (XTmouse_position): Return its current value as the position's
        timestamp.

        * keyboard.c (Qvertical_split): Renamed to `vertical-line',
        since the window arrangement is actually referred to as a
        `horizontal split.'
        (make_lispy_event, make_lispy_movement, syms_of_keyboard): Uses
        renamed here.
        keyboard.h (Qvertical_split): Extern declaration changed here.
        window.c (Fcoordinates_in_window_p): Changed this to return
        `vertical-line' at the appropriate times, rather than
        `vertical-split'.

        * window.c (Fcoordinates_in_window_p): Put symbol names in
        opposing single quotes - `vertical-split', for example.

        * fileio.c (Fexpand_file_name): Don't signal an error if USERNAME
        in a "~USERNAME/..." filename isn't a real user; just leave the
        "~USERNAME" unchanged.

        * fileio.c (Fmake_symbolic_link): Rename argument `NEWNAME' to
        `LINKNAME', to conform with the docstring.

        * Makefile.in (CPP): Pass `-Is -Im' to CPP, to make sure that
        machine- and system-dependend files can include each other
        properly.
        * ymakefile (CFLAGS): Add those directories to the #include path
        here too.

        * Makefile.in (xmakefile): Build this via a temporary file, so
        that if preprocessing fails we don't nuke the xmakefile.

        * fileio.c: There are two versions of Fexpand_file_name defined
        here; the latter is inside a `#if 0' clause.  Change its DEFUN to
        a DEAFUN, so that its docstring doesn't make it into the DOC file
        and supercede the real docstring.

        * callint.c (Fcall_interactively): For the 'K' interactive spec,
        set varies[i] to -1, indicating that the mouse click should be
        quoted if the function makes it into the command history, and that
        this argument by itself does not qualify the command to be
        recorded in the history.

1992-06-26  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * data.c (Frem): The drem function will sometimes return a
        negative number.  If it does, add the divisor to it, to make it
        positive.

        * screen.c: Put '#ifdef MULTI_SCREEN' after the inclusion of
        config.h.

        * window.c (Fpos_visible_in_window_p): Remember to apply XSCREEN
        to w->screen before applying SCREEN_WIDTH.

        * screen.h [not MULTI_SCREEN] (last_nonminibuf_screen): Removed
        #definition of this; it's confusing when debugging.
        * screen.c (last_nonminibuf_screen): Variable moved from here...
        * dispnew.c (last_nonminibuf_screen): to here, beside
        selected_screen.  They should both exist, even if the multi-screen
        support is not present.

        * dispnew.c [not MULTI_SCREEN] (the_only_screen): New variable.
        Instead of having the non-multi-screen version of Emacs refer to
        lots of different variables scattered hither and yon, we'll just
        declare this new variable, of type `struct screen', and define the
        single-screen versions of the `SCREEN_foo' macros to reference its
        elements.  This avoids conflicts between names of local variables
        and names of global variables describing the screen, and simplifies
        some of the differences between the multi-screen and single-screen
        cases.
        * screen.h (enum output_method, struct screen): Removed these from
        the `#ifdef MULTI_SCREEN' conditional.
        * screen.h [not MULTI_SCREEN] (the_only_screen): extern
        declaration for it here.
        [not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS, SCREEN_DESIRED_GLYPHS,
        SCREEN_TEMP_GLYPHS, SCREEN_HEIGHT, SCREEN_WIDTH,
        SCREEN_NEW_HEIGHT, SCREEN_NEW_WIDTH, SCREEN_CURSOR_X,
        SCREEN_CURSOR_Y, SCREEN_ROOT_WINDOW, SCREEN_INSERT_COST,
        SCREEN_DELETE_COST, SCREEN_INSERTN_COST, SCREEN_DELETEN_COST,
        SCREEN_MESSAGE_BUF, SCREEN_SCROLL_BOTTOM_VPOS): Macros changed to
        refer to the_only_screen.
        * dispnew.c [not MULTI_SCREEN] (one_screen_cursX,
        one_screen_cursY, one_screen_current_glyphs,
        one_screen_desired_glyphs, one_screen_temp_glyphs,
        delayed_screen_width, delayed_screen_height): Variables
        deleted; they're all now kept in the_only_screen.
        * xdisp.c [not MULTI_SCREEN] (message_buf): Variable deleted; same
        fate.
        * term.c [not MULTI_SCREEN] (one_screen_width, one_screen_height):
        Variables deleted; same fate.
        * screen.h [not MULTI_SCREEN]: extern declarations for the above
        variables removed.
        * window.c [not MULTI_SCREEN] (root_window): Variable deleted.
        [not MULTI_SCREEN] (init_window_once): Use SCREEN_ROOT_WINDOW to
        refer to the root window, instead of referring to it directly.
        * window.h [not MULTI_SCREEN] (root_window): extern declaration
        removed.
        * scroll.c [not MULTI_SCREEN] (insert_line_cost, delete_line_cost,
        insert_n_lines_cost, delete_n_lines_cost): Variables deleted; same
        fate.

        * dispnew.c [not MULTI_SCREEN] (cursX, cursY): Renamed to
        `one_screen_cursX' and `one_screen_cursY'.
        * screen.h [not MULTI_SCREEN] (cursX, cursY, SCREEN_CURSOR_X,
        SCREEN_CURSOR_Y): extern declarations and macros changed
        accordingly.

        * term.c [not MULTI_SCREEN] (screen_width, screen_height): Renamed
        to `one_screen_width' and `one_screen_height', so as not to
        conflict with local variables when referenced by the `SCREEN_foo'
        macros.
        * screen.h [not MULTI_SCREEN] (screen_width, screen_height):
        extern declarations changed accordingly.
        * termchar.h (screen_width, screen_height): extern declarations
        deleted.  Everyone should go through the `SCREEN_foo' macros.
        (SCREEN_WIDTH, SCREEN_HEIGHT): Changed accordingly.

1992-06-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callint.c (Fcall_interactively): When making a copy of the spec
        string, cast the return value of `alloca' to `unsigned char *',
        not `char *', to match the type of `string'.

        * xselect.c (Fx_own_selection): Cast XSTRING (string)->data to a
        char *, so it can be comfortably passed to XStoreBytes.

        * filelock.c (strcpy): Declare this to return char *.

1992-06-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * dispnew.c (current_glyphs, desired_glyphs, temp_glyphs): Renamed
        to have the prefix `one_screen_', so that the screen macros can
        refer to them without conflicting with local variables.
        * screen.h [not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS,
        SCREEN_DESIRED_GLYPHS, SCREEN_TEMP_GLYPHS): Changed accordingly.

        * keyboard.c (read_key_sequence): Put the code which restarts the
        key sequence in a `#ifdef MULTI_SCREEN' conditional.

        * screen.h [not MULTI_SCREEN]: Added definitions for
        CHECK_LIVE_SCREEN and SCREEN_FOCUS_SCREEN for the non-multi-screen
        case.

        * screen.h [not MULTI_SCREEN]: The name is
        `SCREEN_MINIBUF_ONLY_P', not `SCREEN_IS_MINIBUF_ONLY'.

        * xdisp [not MULTI_SCREEN] (Fredraw_display): Removed definition
        here; the non-multi-screen version is already defined in
        dispnew.c, alongside the multi-screen version.
        (syms_of_xdisp): Don't try to defsubr Sredraw_display; it doesn't
        exist.

        * lread.c (Fread_char_exclusive): Remove this from the `#ifdef
        HAVE_X_WINDOWS' conditional; it is appropriate in any context.

        * eval.c (Fsignal): Put call to TOTALLY_UNBLOCK_INPUT under the
        protection of a `#ifdef HAVE_X_WINDOWS' conditional.

        * keyboard.c (kbd_buffer_get_event): Expect *mouse_position_hook
        to return the timestamp as an unsigned long, not a lisp_Object.
        This matches the change made to `struct input_event'.
        (make_lispy_movement): Change argument TIME to an unsigned long.
        * xterm.c (XTmouse_position): Change TIME argument to a pointer to
        an unsigned long.
        * termhooks.h (mouse_position_hook): Doc fix.
        * term.c (mouse_position_hook): Doc fix.

        * termhooks.h (struct input_event): If MULTI_SCREEN is defined,
        declare the .screen element to be `struct screen *'; otherwise,
        declare it to be `int'.  See the comment in the file for why I've
        done this obviously wrong thing.

        * print.c (printbufidx): Doc fix.
        * xdisp.c (message_buf_print): Doc fix.

        * dispextern.h (message_buf_size): Variable deleted; it's no
        longer used, since the message buffer is always the width of the
        screen.

        * screen.h [not MULTI_SCREEN] (message_buf): Add extern
        declaration for it here.
        (message_buf_print): Added extern declarations here for both the
        MULTI_SCREEN and non-MULTI_SCREEN cases.
        * dispextern.h (message_buf, message_buf_print): Deleted extern
        declaration for these here.  It should never be used directly; it
        should always be used through the SCREEN_MESSAGE_BUF macro.

        * dispnew.c (temp_glyphs): Added back this variable declaration;
        screen.h and various other places referred to this; where did it
        go?
        * screen.h [not MULTI_SCREEN] (temp_glyphs, desired_glyphs,
        current_glyphs): Add extern declarations for these.

        * dispnew.c (cancel_my_columns): Use SCREEN_DESIRED_GLYPHS macro,
        instead of assuming that a SCREEN_PTR is actually a pointer to
        something; it isn't if we're not using any of the screen support.
        Remove the variable `screen', and find the value for
        `desired_glyphs' directly.
        * xdisp.c (echo_area_display): Use the SCREEN_DESIRED_GLYPHS macro
        to find screen's desired cursor position, instead of assuming that
        a SCREEN_PTR is a pointer to something.
        (display_mode_line): Same.
        * window.c (Fpos_visible_in_window_p): Use the SCREEN_WIDTH macro.
        (replace_window): Use the SCREEN_ROOT_WINDOW macro.
        (window_loop): Use the SCREEN_WIDTH macro.

        * dispnew.c (update_screen): Enclose the statement which
        increments `downto' in a `#ifdef HAVE_X_WINDOWS' conditional.

        * screen.h [MULTI_SCREEN and not MULTI_SCREEN] (FOR_EACH_SCREEN):
        New macro.
        * dispnew.c (window_change_signal, do_pending_window_change): Use
        FOR_EACH_SCREEN instead of assuming that Vscreen_list exists.
        * window.h (root_window): Added extern declaration for this.

        * screen.c: Enclose the entire file in a #ifdef MULTI_SCREEN
        conditional.


1992-06-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * window.c (Fset_window_dedicated_p):
        Replaces Fset_window_buffer_dedicated.  Second arg just t or nil.

1992-06-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * syntax.h (SYNTAX, SYNTAX_MATCH, SYNTAX_COMSTART_FIRST, etc.)
        Cast character to unsigned char before indexing.

1992-06-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (x_wm_set_size_hint): Set size_hints.flags to indicate
        that we are providing the base_width and base_height data.

        * xfns.c (Fx_create_screen): Default the internal border width to
        2; this matches XTerm.

        * syntax.c (Fparse_partial_sexp): Doc fix.

        * syntax.c (Fparse_partial_sexp): Added phony argument list to
        comment containing the docstring for this function, so that
        make-docfile.c will get the right arguments.

        * xfns.c (x_set_name): Don't go through the X11 brouhaha to set
        the name unless we're actually setting it to something different
        from the current name.

1992-06-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * eval.c (syms_of_eval): Don't forget to escape the ends of the
        lines in the docstring for `debug-on-quit'.

        * keyboard.c (Fread_key_sequence): Reversed sense of CONTINUE_ECHO
        argument - set this_command_key_count to zero iff CONTINUE_ECHO is
        Qnil, not iff it's non-Qnil.

1992-06-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
        
        * search.c: Changed to remember the object in which the last
        search was done, so that markers from match data are placed in
        that buffer, instead of the current buffer.
        (search_regs_from_string): Replaced with...
        (last_thing_searched): This is either Qnil, meaning no searching
        has been done, Qt, meaning that the last search was done in a
        string, or a buffer object, meaning that the last search was done
        in that buffer.
        (syms_of_search): Initialize and staticpro last_thing_searched.
        (Flooking_at, search_buffer): Set last_thing_searched to the
        current buffer.
        (Fstring_match): Set last_thing_searched to Qt.
        (Fmatch_data): Test last_thing_searched to see if any searching
        has been done, and construct integers or markers in the right
        buffer.  Abort if it's not Qt, Qnil, or a buffer.
        (Fstore_match_data): Set last_thing_searched according to the
        things we find in LIST.
        
1992-06-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * fns.c (Fload_average): Document the fact that this sometimes
        returns a list of fewer than three elements, on systems which
        don't provide 5- and 15-minute load averages.

1992-06-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
        
        * xterm.c (XTread_socket): If an event arrives to a screen S,
        don't attribute them to SCREEN_FOCUS_SCREEN (S) here.  Do that
        synchronously, when the events are dequeued.  This keeps events
        from being accidentally routed to the wrong screen, if we
        temporarily redirect a screen's focus.
        * keyboard.c (kbd_buffer_store_event): If the character being
        stuffed is a quit character, do the SCREEN_FOCUS_SCREEN
        redirection to it here.
        (kbd_buffer_get_event): And do it here, before returning the
        event.
        
        * eval.c (Finteractive_p): This assumed that if the function in
        the top frame of the lisp backtrace was not a Lisp_Compiled
        object, then Finteractive_p must have an explicit frame on the top
        of the stack, which we could skip.  It didn't bother to follow the
        symbol function chaining, and it would break if any C code called
        from a non-compiled function tried to call Finteractive_p anyway.
        Changed this to actually check if the top frame's effective
        function is the Lisp_Subr for Finteractive_p.  This also used to
        skip any number of frames for special forms and/or Fbytecode
        calls.  Changed this to skip an Fbytecode frame (if present),
        followed by any number of special form frames.

1992-06-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * eval.c (struct backtrace): Doc fix.

1992-06-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * m/hp300bsd.h (LOAD_AVE_TYPE): This is long, not double.
        (LOAD_AVE_CVT): Adjusted as appropriate.

        * fns.c: Moved lots of system-dependent preprocessor cruft
        dealing with getting the load average to `getloadavg.c'.
        (Fload_average): Guts moved to `getloadavg.c'.
        * getloadavg.c: New file, containing the necessary mess to get the
        load average on many different systems.  This file is supposed to
        be Emacs-independent.
        * ymakefile (obj): Add getloadavg.o to the list.
        (getloadavg.o): Note that this depends on its source, and config.h.

        * screen.c (Fdelete_screen): Typo in loop looking for new
        last_nonminibuf_screen - change `screen = XCONS (screens)->cdr`
                                     to `screens = XCONS (screens)->cdr`

        * xdisp.c (echo_area_display): Don't neglect to draw all the lines
        of the minibuffer window (or echo area) when a message is being
        displayed.  If the minibuffer is more than one line high, they
        should all be blanked.

1992-06-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * sysdep.c [POSIX_SIGNALS] (sys_signal): Fix typo - rather than
        calling new_action as if it were a function, call sigaction.

1992-06-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * lisp.h (Qnumberp, Qnumber_or_marker_p): Declared.

        * eval.c (wants_debugger): Changed NULL to NILP.
        Who installed these calls to NULL?

1992-06-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * dispnew.c (Fsit_for): Don't forget to actually set sec from ARG.

        * termhooks.h (struct input_event): Doc fix - for mouse clicks, .x
        and .y give the position in characters, not in pixels.

        * keyboard.c (format_modifiers): Order the modifier letters
        alphabetically - control, meta, shift, and up.

1992-06-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * xfns.c: Move some extern decls out of #if 0, to top of file.

1992-06-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * window.c (Fcoordinates_in_window_p): Docstring fix.

        * buffer.c (Fother_buffer): Put a comma between arguments BUFFER
        and VISIBLE_OK in the argument list.  Duh.

        * screen.c (Fdelete_screen): Remember that s is a SCREEN_PTR *,
        not a Lisp_Object.

        * search.c (search_regs): Doc fix.
        (compile_pattern): Take a new argument - the search register
        structure - so we can reassure the regex routines that the
        registers have been allocated.
        (Flooking_at, Fstring_match, search_buffer): Changed to pass
        &search_regs to compile_pattern.
        (search_buffer): When we've searched for a literal string and
        found it, make sure that the search registers are allocated before
        stuffing the location of the search into them.
        (Fstore_match_data): If we need to allocate more registers,
        allocate them using re_set_registers, instead of just storing the
        new registers and hoping that regex doesn't free them.

        * search.c (Freplace_match): Doc fix.

1992-06-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * screen.c (Fdeiconify_screen): Function deleted.
        It was the same as make-screen-visible.

1992-06-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * keyboard.c: Doc fix.

        * floatfns.c (Fcbrt): Renamed from Fcube_root, and #if 0'd.

        * lisp.h (CHECK_NUMBER_OR_FLOAT*): Use Qnumberp or Qnumber_or_marker_p.
        * data.c (syms_of_data): Staticpro those.
        (Qinteger_or_float_p, Qinteger_or_float_or_marker_p): Deleted.
        (Fnumberp, Fnumber_or_marker_p): Define these always,
        but make them work even if not LISP_FLOAT_TYPE.

1992-06-05  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * config.h.in: Undefine REL_ALLOC if a system specific file
        defines SYSTEM_MALLOC.

        * sysdep.c (save_signal_handlers): Cast result of signal  to
        avoid compiler warning.
        * process.c (send_process): Likewise.

1992-06-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
        
        * keyboard.c (Fread_key_sequence): New 2nd arg CONTINUE_ECHO
        added for the sake of universal-argument.
        
1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * editfns.c (Fset_default_file_mode): Function deleted.
        (Funix_sync): Moved.
        * fileio.c (Funix_sync): Moved to here.

        * xfns.c (Fx_erase_rectangle, Fx_draw_rectangle, Fx_contour_region):
        (Fx_uncontour_region): #if 0 these.
        (x_rectangle, outline_region): Likewise.
        (syms_of_xfns): #if 0 the defsubrs.

        * dispnew.c (Fsleep_for, Fsit_for): Clean up error messages.

        * eval.c, print.c, keyboard.c: Doc fix.

        * xfns.c (Fx_horizontal_line): Disabled, since not documented.

        * fileio.c (Fdelete_directory): Renamed from Fremove_directory.

        * unexencap.c: Deinstalled (renamed to =unexencap.c)
        since awaited papers never arrived.

        * xfns.c: Doc fix.

1992-06-04  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * eval.c (stack_trace_on_error, debug_on_error): Made Lisp_Objects V*.
        (syms_of_eval): Changed DEFVAR_BOOLs to DEFVAR_LISPs.
        (wants_debugger): New fn.
        (find_handler_clause): Use it to look in debug-on-error and
        stack-trace-on-error lists.

1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * floatfns.c (Fbessel_*, Ferf, Ferfc, Flog_gamma): Turned off;
        not clearly worth including.
        (Fasinh, Facosh, Fatanh, Fsinh, Fcosh, Ftanh): Likewise.

1992-06-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * minibuf.c, keyboard.c: Doc fix.

        * window.c (Fwindow_at): Fix number of args--minimum 2, max 3.

        * screen.c: Doc fix.

1992-06-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * lread.c (Feval_buffer): Don't read any arguments, if interactive.

1992-06-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * screen.c (make_screen_without_minibuffer): Apply XSCREEN to
        Vdefault_minibuffer_screen before calling SCREEN_LIVE_P.  The
        argument to SCREEN_LIVE_P must be a SCREEN_PTR, not a Lisp_Object.

        * dispnew.c (Fsit_for): This used to compare arg with 0 and return
        Qt immediately.  It should actually call sit_for anyway, because
        sit_for needs to test for input and do the redisplay.
        (sit_for): Compare sec and usec with zero here, after we've
        looked for input and done a redisplay.

        * lread.c (Feval_buffer): Use NILP, not NIL_P.

1992-06-01  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * buffer.h: New macro, BUF_SET_PT.

        * lread.c: New subr `eval-buffer', replaces `eval-current-buffer',
        which is now defined in simple.el.

1992-05-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * screen.c (Fdelete_screen): If we're deleting the default
        minibuffer screen, try to find another minibuffer screen.

1992-05-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * buffer.c (Fother_buffer): New optional argument VISIBLE_OK,
        indicating that buffers currently visible in windows should not be
        discriminated against.

1992-05-28  Ken Raeburn  (raeburn@cygnus.com)
        
        * screen.c (Fdelete_screen): Fix bugs in walking screen list.
        (make_screen_without_minibuffer): Signal an error if the default
        minibuffer screen is dead.
        
        * xfns.c (x_set_name): Use ICCCM-conforming scheme for changing
        window name in X11.
        (Fx_create_screen): Likewise.

1992-05-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xselect.c: Support getting and setting the obsolete X cut
        buffers.
        (Qcut_buffer0): New atom, denoting the X cut buffer 0.
        (syms_of_xselect): Initialize and staticpro it.
        (Fx_own_selection): If TYPE is Qcut_buffer0, interpret this to
        mean that we should set cut buffer 0 to STRING.
        (Fx_selection_value): If TYPE is Qcut_buffer0, interpret this to
        mean that we should retrieve the value of cut buffer 0.

1992-05-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (construct_mouse_click): Removed extra assignment of
        result->timestamp.

        * keyboard.c (last_event_timestamp): Doc fix.
        * xselect.c (last_event_timestamp): Declare it extern here.
        (mouse_timestamp): Variable deleted.  last_event_timestamp is a
        more accurate thing to use here.
        (own_selection, get_selection_value): Use last_event_timestamp
        instead of mouse_timestamp.
        * keyboard.c (make_lispy_event): Pass the event's timestamp
        through the make_number function, to assure that it is properly
        tagged before incorporating it into the lispy event.
        * xterm.c (construct_mouse_click): The timestamp element of a
        struct input_event is no longer a Lisp_Object; it is now an
        unsigned long.  So don't use XSET to assign to it.
        (XTread_socket): Same here, in processing KeyPress events.

        * keyboard.c (Fexecute_extended_command): Properly initialize
        this_command_keys to the concatenation of the sequence that
        invoked Fexecute_extended_command, the characters making up the
        name of the command we're running, and a return character.
        Previously, this code would set it to the last key typed while
        reading the function name from the minibuffer, followed by the
        name of the function being run.

1992-05-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (x_display_box_cursor): Draw the cursor at curs_{x,y},
        rather than at s->cursor_{x,y}.  If cursor_in_echo_area is set,
        then s->cursor_{x,y} does not accurately describe the position of
        the cursor.  However, if we're not updating, then curs_{x,y} are
        garbage; set them from s->cursor_{x,y}.

        * dispnew.c (update_screen): Check current_screen->enable and
        current_screen_used to see if there is any text on the last line,
        not desired_screen->{enable,used}.  When the line isn't enabled,
        move to line SCREEN_HEIGHT (s) - 1, not SCREEN_HEIGHT (s).
        Rearranged conditionals.

        * dispnew.c (cursor_in_echo_area): Document the interpretations of
        positive and negative values of this variable.

1992-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * dispnew.c (Fding): If have arg, don't end a keyboard macro.

1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * dispnew.c (sit_for): New function, which is a slight
        generalization of Fsit_for; you can tell it that it's waiting for
        input, so C-g gets handled properly.
        (Fsit_for): Call it, instead of replicating all its guts.
        * keyboard.c (read_char): Call sit_for instead of Fsit_for, and
        indicate that we're awaiting keyboard input.

        * dispnew.c (Fsit_for): Rename arguments to match docstring.  Use
        NILP instead of EQ (foo, Qnil).  If nodisp is non-nil, call
        wait_reading_process_input with do_display 0, instead of 1; this
        will inhibit spurious redisplays when process input arrives during
        a sit-for.

        * process.c (Faccept_process_output): Pass zero as read_kbd
        argument to wait_reading_process_input when PROC is nil, not when
        PROC is non-nil.

        * process.c (wait_reading_process_input): Declare read_kbd to be a
        Lisp_Object, and use the tagging to tell the difference between a
        process object and an integer.
        * dispnew.c (Fsleep_for, Fsit_for, Fsleep_for_millisecs): Pass
        read_kbd argument to wait_reading_process_input as a Lisp_Object.
        * keyboard.c (kbd_buffer_get_event): Same.
        * process.c (Faccept_process_output, send_process): Same.

        * keyboard.c (read_char): Use save_getcjmp and restore_getcjmp
        instead of doing the bcopy explicitly.

        * xterm.c (XTread_socket): When handling an EnterWindow event,
        don't bother to check waiting_for_input.  It's not necessary.

        * keyboard.c (read_char): Don't clear waiting_for_input and
        input_available_clear_time here.
        (quit_throw_to_read_char): It's already done here.

        * keyboard.c (quit_throw_to_read_char): Use
        clear_waiting_for_input instead of clearing waiting_for_input
        explicitly.

1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * keyboard.c (read_char): Call clear_waiting_for_input instead of
        clearing waiting_for_input and input_available_clear_time
        explicitly.

1992-05-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * ymakefile [defined (__GNUC__) and __GNUC__ > 1]: define
        YMF_PASS_LDFLAGS so that it can deal with an empty flags argument.

        * callproc.c (Fcall_process): Under VMS, a nil INFILE argument
        means to read from "NLA0:", not "/dev/null".

        * callproc.c (Fcall_process): Use nil as the value for display
        (the fourth argument) when nargs >= 4, not when nargs >= 3.

1992-05-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
        
        * termhooks.h: Change timestamp from a Lisp_Object to an unsigned
        long.
        * keyboard.c (kbd_buffer_store_event): We don't have to apply the
        XINT macro to the timestamp member of the event anymore.

        * process.c (wait_reading_process_output): Don't turn off polling.

        * sysdep.c (setpgrp_of_tty): Pass the address of pid, not pid
        itself.

        * process.c: Deleted cpp tangle for dealing with system-dependent
        tty handling; #included "systerm.h".
        * systerm.h: Add some of the things that were done in process.c:
        If titan is #defined, then we should include <sys/ttyhw.h> and
        <sys/stream.h> along with the other SYSV pty stuff.
        If HPUX is #defined, then EMACS_HAVE_TTY_PGRP isn't true.
        If XENIX is #defined, then we shouldn't try to use TIOCGETC.
        * ymakefile: Note that process.o depends on systerm.h now.

1992-05-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * callint.c (Fprefix_numeric_value): Value 1 for symbol other than `-'.

1992-05-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * cmds.c (Fforward_line): If the buffer is empty, don't try to see
        if it contains a newline, and moving nowhere at eob after
        non-newline should return 1, not 0.

        * search.c (scan_buffer): Doc fix.

        * buffer.c (Fbuffer_disable_undo): Accept a buffer name as an
        argument.

1992-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c: Include config.h first thing.       
        
        * keyboard.c (clear_input_pending): New subroutine.
        * process.c (wait_reading_process_input): Make C-g really quit in
        sit-for case.

        * ymakefile (LD_SWITCH_SYSTEM): Don't use -X with GCC.

1992-05-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * eval.c (Fapply): Use indirect_function, instead of doing a dumb
        loop.
        * keymap.c (get_keymap_1): Same.
        * macros.c (Fexecute_kbd_macro): Same.

        * buffer.c (init_buffer_once): Don't disable undos for *scratch*
        here.  Do it in loadup.el.

        * buffer.c (init_buffer_once): Doc fix.

        * doc.c (Fdocumentation): After extracting the doc string from a
        lambda or autoload expression, don't fall through to the default
        case and signal an invalid function error; instead, do a `break'.

        * doc.c (Fdocumentation): Use EQ (x, y) instead of XSYMBOL (x) ==
        XSYMBOL (y).

        * doc.c (Fdocumentation): When decyphering a function made from
        conses, use 'else if' for the chain of alternatives instead of
        just 'if'.  It used to be that each alternative returned, but
        that's not true anymore.

        * alloc.c (Fgarbage_collect): Don't call truncate_undo_list on
        buffers whose undo list is 't.

        * doc.c (Fdocumentation): Renamed argument `fun1' to `function',
        so make-docstring will list argument consistently with the
        docstring.

1992-05-11  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

        * xterm.h: Removed definition of `RES_CLASS'.

        * xfns.c (x_get_arg): Eliminated `screen_name' parameter.  No
        longer uses screen name as X resource search component.
        All calls to x_get_arg changed accordingly.
        Global variable `screen_class' and #define `SCREEN_CLASS' removed.

        * xterm.c (XTread_socket): Added basic structure for handling
        various ClientMessage events, using new global variables
        `Xatom_wm_take_focus', `Xatom_wm_save_yourself',
        `Xatom_wm_delete_window', `Xatom_wm_configure_denied',
        `Xatom_wm_moved'.
        * xfns.c: Declare these variables extern.
        (syms_of_xfns): Initialize these variables.

        * xselect.c (Fx_own_selection, Fx_selection_value): New optional
        parameter `type', to specify the selection type.
        (syms_of_xselect): New symbols Qprimary, Qsecondary, Qclipboard
        initialized.

1992-05-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * data.c (Qcyclic_function_indirection): New error condition.
        (indirect_function, Findirect_function): New functions.
        (syms_of_data): Initialize Qcyclic_function_indirection, put the
        error properties on it, and staticpro it.  Defsubr
        Findirect_function.
        * lisp.h (indirect_function, Findirect_function): Declare them here.
        * callint.c (Fcall_interactively): Get symbol's function by
        calling indirect_function, instead of just looping.
        * doc.c (Fdocumentation): Same.
        * eval.c (Finteractive_p, Fcommandp, do_autoload, Feval,
        Ffuncall): Same.
        * keyboard.c (Fcommand_execute): Same.

        * data.c (Fsymbol_function): Name the argument `symbol' instead of
        `sym', so make-docstring will list argument consistently with the
        docstring.

        * process.c (wait_reading_process_input): Make sure the screen
        isn't garbaged (and therefore not displayed) before we enter the
        select and start waiting for input.

        * keyboard.c: #include <systime.h>.
        * ymakefile (keyboard.o): This depends on systime.h.
        * keyboard.c (input_available_clear_word): Replaced with
        input_available_clear_time, which is a pointer to an EMACSTIME;
        sometimes the time information is larger than a single word.
        (read_char): Changed ..._word to ..._time.
        (input_available_signal): Use the EMACS_SET_SECS_USECS macro to
        clear *input_available_clear_time, instead of zapping a zero into
        *input_available_clear_word.
        (set_waiting_for_input, clear_waiting_for_input): Adjusted
        appropriately.

1992-05-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * editfns.c (make_buffer_string): New function.
        * lisp.h (make_buffer_string): Declare it here.
        * editfns.c (Fbuffer_substring): Call make_buffer_string instead
        of writing it out.
        (Fbuffer_string): Call make_buffer_string instead of make_string,
        so we can deal with buffer relocations.
        * minibuf.c (read_minibuf): Same here.

1992-05-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * syssignal.h (sigunblock): New macro, taken from 18.58's
        emacssignal.h file.
        * sysdep.c (request_sigio): Use the sigunblock macro to enable
        reciept of SIGWINCH, instead of the dysfunctional sigblockx.

1992-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * search.c: Doc fix.

1992-05-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * emacs.c (decode_env_path): If EVARNAME is zero, don't try to
        call getenv on it.
        * lread.c (init_lread): When we don't have an environment variable
        to check, pass 0 instead of the empty string.

        * alloc.c (Fmake_marker): Use `SIGMASKTYPE' instead of `int'.
        Instead of calling sigsetmask twice - once to get the mask, and
        again to restore it - call sigblock, specifying no additional
        signals.

1992-05-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * alloc.c: #include <syssignal.h>, for the sake of the
        bug-catching code in Fmake_marker.
        ymakefile: Add dependency.

        * syssignal.h [not POSIX_SIGNALS] (SIGFULLMASK): New definition,
        for symmetry with the "defined (POSIX_SIGNALS)" case.

        * callproc.c (child_setup): Since we always get the environment
        from Vprocess_environment, don't bother to take the environment
        the subprocess should inherit as an argument anymore.
        * process.c (create_process): Don't pass environment as a
        variable.  Just preserve it across call to fork.

1992-05-04  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * floatfns.c: #include <syssignal.h>.
        (float_error): Use SIGEMPTYMASK instead of zero.
        
        * syssignal.h [POSIX_SIGNALS] (sigmask): Defined to expand to a
        statement expression under GCC, or a function call otherwise.
        (sigpause, sigblock, sigunblock, sigsetmask): These are now
        K&R-compatible macros.
        * systerm.h [POSIX_SIGNALS] (sys_sigmask): Here is the function
        the POSIX version of sigmask calls when we're not compiling with
        GCC.
        * alloc.c (Fmake_marker): Undo changes of Apr 29.
        * callproc.c (Fcall_process): Same.
        * data.c (arith_error): Same.
        * floatfns.c (float_error): Same.
        * keyboard.c (gobble_input): Same.

        * sysdep.c (request_sigio, unrequest_sigio)

1992-04-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * x11term.h (CLASS): Change this from "emacs" to "Emacs"; class
        names should always start with an upper-case letter.

        * syssignal.h: Arranged cpp conditionals so that the specific
        cases come first, generic cases last.

        * syssignal.h (sigpause, sigblock, sigunblock, sigsetmask): Macros
        removed; they require GCC, and Emacs 19 should compile without GCC.
        (EMACS_SIGPAUSE, EMACS_SIGBLOCK, EMACS_SIGUNBLOCK,
        EMACS_SIGSETMASK, EMACS_SIGFREE, EMACS_SIGHOLDX, EMACS_SIGBLOCKX,
        EMACS_SIGUNBLOCKX, EMACS_SIGPAUSEX): These are new macros that
        don't require GCC, but expand to statements.
        * callproc.c (Fcall_process): Use new EMACS_SIG* macros from
        syssignal.h.
        * keyboard.c (gobble_input): Same.
        * sysdep.c (request_sigio, unrequest_sigio): Same.
        * x11term.h (BLOCK_INPUT, UNBLOCK_INPUT): Same.
        * alloc.c (Fmake_marker): Same.
        * data.c (arith_error): Same.
        * floatfns.c (float_error): Same.

1992-04-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * ymakefile: If we're using GCC version 2.0 or later, use "$(CC)
        -nostdlib" as the linker.  This will allow us to find libgcc.a
        even when GCC puts it in a really weird place.
        (YMF_PASS_LDFLAGS): New macro.
        (temacs): Use it.

        * s/hpux.h: Doc fix.

        * filelock.c (egetenv): Declare this.
        (lock_path, SUPERLOCK_NAME, superlock_path): New variables and
        macros.
        (MAKE_LOCK_PATH, lock_file, unlock_file, lock_superlock): Use the
        variables lock_path and superlock_path instead of the PATH_LOCK
        and PATH_SUPERLOCK macros.
        (init_filelock): New function.
        * emacs.c (main): Call the init_filelock function.
        * paths.h.in (PATH_SUPERLOCK): Removed.  This is now calculated
        from PATH_LOCK or from the EMACSLOCKDIR environment variable.

        * filelock.c (MAKE_LOCK_PATH): New macro.
        (lock_file, unlock_file, Ffile_locked_p): Use it.

        * syntax.c (Fmodify_syntax_entry): Note that '-' is a synonym for
        ' ' (both denote whitespace), that '\\' denotes the escape class,
        and that '/' denotes the character-quote class.  The description
        used to claim that '\\' denoted the character-quote class, and
        neglected to mention '-' and '/'.

        * filelock.c (lock_file): Doc fix.

1992-04-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callproc.c (init_callproc): Get the default Vexec_path from the
        environment variable "EMACSPATH"; get Vdata_directory from
        "EMACSDATA".

        * ymakefile: Fix #endif and #else comments.

1992-04-27  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * ymakefile (xemacs): Link xemacs to temacs if HAVE_SHM.

        * ymakefile (paths.h, config.h): Never copy, always fail.

        * process.c (wait_reading_process_input): Redisplay if screen_garbaged.
        Call do_pending_window_change first.
        Include dispextern.h.
        * ymakefile (process.o): Added dependency.

        * ymakefile (OLDXMENU_OPTIONS): New macro, used compiling oldxmenu.

1992-04-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * ymakefile: Changed all references to LD_CMD to LINKER, for
        compatibility with the 18.58 configuration files.
        * s/aix3-1.h, s/sunos4shr.h: Same here.

        * ymakefile: Doc fixes.

        * ymakefile (CC, MAKE): Set these variables from optional macros.
        Change all uses of `make' to ${MAKE}.

        * ymakefile: use HAVE_X11 as alias for X11.

        * ymakefile (LIB_GCC, GNULIB_VAR): Handle GCC 2.

        * process.c (allocate_pty): Re-arranged conditionals to put the
        system-specific-case first, and the generic case in the #else
        section, for consistency with the rest of Emacs.

        * process.c (allocate_pty): Wait until we fail to open three ptys
        in a row before concluding that we've reached the end of the ptys.

1992-04-22  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * ralloc.c: #include "getpagesize.h".

        * search.c (Flooking_at): Use search_regs.num_regs instead of
        RE_NREGS.  As of regex version 0.4, the compiler allocates the
        registers, and may allocate more than RE_NREGS.
        (search_buffer): Same.
        (Freplace_match): Use search_regs.num_regs to tell how many
        registers are valid.  Also note that if none are valid, no search
        has been performed.
        (match_limit): Same.
        (Fmatch_data): Same.
        (Fstore_match_data): If we're trying to store more registers than
        search_regs has allocated, re-allocate them to make room.

1992-04-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)


        * callproc.c (egetenv): Declare the type of VAR.

        * lisp.h: Don't undefine NULL.  There is no longer any conflict.

        * lisp.h (NUMBERP): New macro.
        * editfns.c (Fformat): Protect the sections that deal with
        Lisp_Float objects with a "#ifdef LISP_FLOAT_TYPE".
        * bytecode.c (Fbyte_code): Use the NUMBERP macro instead of
        explicitly checking for the Lisp_Float tag.
        * callint.c (Fcall_interactively): Same here.

        * xrdb.c (magic_searchpath_decoder): Re-allocate string as needed,
        rather than making it a fixed-size array.

        * xfns.c (Fx_rebind_key): Don't declare modifier_list to be a
        register variable.  It's too big, and we need the address of its
        first element when we pass it to XRebindKeysym anyway.

        * fileio.c (Fdo_auto_save): Doc fix.

1992-04-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * search.c (search_buffer): Cast RE_EXACTN_VALUE to char, because
        the regex-0.4 distribution says so.

        * ymakefile (dired.o): This depends on regex.h.

        * process.c (wait_reading_process_input): There is code here which
        sends SIGIO to Emacs if we thought we had input available but
        didn't get SIGIO.  If the system doesn't have SIGIO, then
        #ifdef it out.

        * print.c (Fexternal_debugging_output): Arguments were declared
        ANSI-style - rewritten in K&R 1 fashion.

        * floatfns.c (IN_FLOAT): Cast the zero in the `else' clause of the
        conditional expression to SIGTYPE, to match the type of the
        float_error call in the `then' clause.

        * s/hpux8: #define HPUX8; this is supposed to be customary
        procedure, and fileio.c was expecting it, but somehow it didn't
        get defined.

        * sysdep.h: Move inclusions of [AIX] <sys/hft.h>,
        <sys/devinfo.h>, <sys/pty.h>, <unistd.h> [NEED_BSDTTY]
        <sys/bsdtty.h>, [HPUX and HAVE_PTYS] <sys/ptyio.h>, [SYSV_PTYS]
        <sys/tty.h>, <sys/pty.h>, and [pfa] <sys/file.h> to systerm.h;
        also move undefinition of LLITOUT under BSD4_1 to systerm.h.
        * systerm.h: They're here.

        * xterm.c (XTcursor_to, XTclear_end_of_line): Declare to return
        int in the function definitions as well as their declarations.

1992-04-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * fileio.c (directory_file_name): When checking if the string ends
        with '/', check that slen is a valid length *before* examining
        dst[slen-1], not after.

1992-04-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * xterm.c (x_death_handler): New function.
        (x_error_handler): Call x_death_handler to shut down Emacs.
        (x_term_init): Use x_death_handler to handle SIGPIPE, instead of
        x_error_handler, which expects to be passed a display and an
        event.
        * process.c (send_process): This used to set a handler to
        catch SIGPIPEs when writing to a subprocess, and then set the
        handler to SIGDFL after writing, but this would stomp on the
        SIGPIPE handler for for the X connection.  So restore the prevous
        handler instead of changing to SIGDFL.

1992-04-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * indent.c (compute_motion): Fix skipping invis lines and
        truncation at right margin.

1992-04-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * s/hpux.h (PTY_NAME_SPRINTF, PTY_TTY_NAME_SPRINTF): Use pty_name,
        not ptyname. 
        * s/rtu.h: Same.

        * process.c (pty_process): Add 'int' to the declaration 'static
        pty_processes;'.  This makes it a happy declaration even when
        static has been #defined as the empty string.
        * xterm.c (XTcursor_to, XTclear_end_of_line): Same.

        * unexec.c (sbrk): Declare this to return void * if __STDC__ is
        defined, or char * otherwise.

        * lread.c init_lread): Re-cleaned logic.  To determine whether the
        load path was changed before dumping, cons up a dump path and
        compare it.  This method is more localized and accurate.
        (initial_path): Variable removed.
        (syms_of_lread): Don't staticpro.

        * floatfns.c (float_error): Declare and define this to return
        SIGTYPE.

        * systime.h [HAVE_TIMEVAL] (EMACS_GET_TIME): Declare dummy to be a
        real struct timezone, instead of an EMACS_TIME.  Since
        HAVE_TIMEVAL is defined, struct timezone ought to be declared, so
        there's no harm in passing the genuine article.

        * sysdep.c [USG] (rename): Place under the protection of a new
        preprocessor symbol, HAVE_RENAME.
        * s/hpux.h (HAVE_RENAME): Defined.

        * sysdep.c [USG] (setpriority): Declare to return int, not void.

        * s/template.h: Add template section for HAVE_TERMIOS.

        * term.c (cursor_to, raw_cursor_to, fatal): Do declare the types
        of the arguments.

1992-04-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callint.c (Fcall_interactively): When the interactive spec is
        a string, it may be relocated while reading the arguments.  To
        avoid this, make a copy of the spec to refer to, instead of
        using a pointer to the data of the spec string.

        * callint.c (Fcall_interactively): When following the function
        chain of a symbol, check for quits.

1992-04-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * lread.c (init_lread): Make the load path default to
        PATH_LOADSEARCH when we're not dumping (null purify-flag), and
        PATH_DUMPLOADSEARCH when we are (not (null (purify-flag))).
        Change from April 7th incorrectly always used PATH_DUMPLOADSEARCH.

        * lread.c (init_lread): Cleaned up logic; to determine whether the
        load path was changed before dumping, remember the initial value
        and compare against it.
        (initial_path): New variable to support this.
        (syms_of_lread): staticpro initial_path.

        * ymakefile: Renamed filenames like "*-dist" to "*.in".

        * config.h.in: Doc fixes.

1992-04-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * config.h-dist: Renamed to config.h.in, for consistency with
        the installation conventions of other GNU programs.
        * paths.h-dist: Renamed to paths.h.in.

1992-04-11  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)

        * termcap.c: Declare getenv.

1992-04-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * Makefile: Renamed to Makefile.in; the configure script will edit
        this to produce Makefile.

1992-04-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * paths.h-dist (PATH_DUMPLOADSEARCH): New macro.
        * lread.c (init_lread): If we're building an Emacs to be dumped,
        use PATH_DUMPLOADSEARCH as the default load path, so we can
        correctly find our lisp files.

        * config.h-dist, paths.h-dist: Added "-*- C -*-" to top lines, so
        Emacs will know that these are really C source.

1992-04-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * search.c (syms_of_search): When allocating memory
        searchbuf.buffer, cast the return value of malloc to unsigned char
        *, not char *; this changed in the most recent version of the
        regex code.

1992-03-31  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * doc.c (Fdocumentation): Don't forget to end each line of the
        docstring with "\n\".

        * process.c (Fprocess_connection): Change "#ifdef 0" around this
        function to "#if 0".

        * eval.c (Flet, FletX): Signal an error if one of the let's binding
        clauses has more than one value form, as in (let ((a 1 2)) a).

        * eval.c (Ffuncall): Re-install change of March 10; I don't know
        why it went away.

        * search.c (compile_pattern): Declare the variable which holds the
        return value of re_compile_pattern to be const, if this is ANSI C.

        * alloc.c (xrealloc): Change "ese" to "else".

        * crt0.c (start1) [sun_soft]: Change 'jst' to 'jsr'.  The Sun
        assembly language manual doesn't list any 'jst' instruction, I
        don't know of one personally, and all the analogous code
        around it uses 'jsr'.

        * crt0.c [m68k]: Merged with GNU C Library's version: added
        conditionals for sun_68881, sun_fpa, sun_soft.

        * config.h-dist: Adjusted for renaming of share-lib to etc.
        * lread.c (read1): Same.
        * doc.c (Fdocumentation_property, Fsnarf_documentation): Same.
        * ymakefile: Same.

1992-03-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * crt0.c: Merged changes from 18.58:
        [hp9000s300]: Set flag_fpa.  Define float_loc.
        [new hp assembler]: Double flag_fpa and flag_68881 if %d2!=0.
        (start1): Declare to be static at the top of the file.
        (_start): Removed static declaration in this function; since
        everyone wants it, we'll just put it here.

1992-03-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c (Finsert_file_contents): Allow quitting from I/O.
        (Fcopy_file): Likewise.

1992-03-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * m-intel386.h (HAVE_ALLOCA): Inhibit if C_ALLOCA.
        (LIB_STANDARD): Alternate USG value if __GNUC__ or C_ALLOCA

        * alloc.c (xrealloc): If handed a NULL pointer for the block to
        resize, malloc a new block and return that.  Not all reallocs do
        this.

        * m/elxsi.h: Doc fix.

1992-03-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * dispnew.c (Fsleep_for): Call wait_reading_process_input, whether
        or not we have process support; let the emulator do the work.
        * emacs.c (fatal_error_signal, Fkill_emacs): Call
        kill_buffer_processes even when subprocesses is not #defined; we
        have a stub.

        * process.c [not defined (subprocesses)] (Fget_buffer_process,
        init_process, syms_of_process): New stub versions of these functions.
        * emacs.c (main): Call init_process and syms_of_process whether or
        not subprocesses is #defined.
        * xdisp.c (decode_mode_spec): Call Fget_buffer_process whether or
        not subprocesses is #defined.

1992-03-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * keyboard.c (kbd_buffer_get_event): Call
        wait_reading_process_input, even when subprocesses is not
        #defined, instead of doing a whole lot of hairy SIGIO-pausing
        stuff.
        * dispnew.c (Fsit_for): Call wait_reading_process_input, whether
        or not subprocesses is #defined.

        * process.c (wait_reading_process_input): Since we're no longer
        checking for exceptional conditions in the call to select, all of
        the different ways to call select for different systems have
        become the same; remove the #if conditionals around this.

        * keyboard.c (read_char): When returning quit_char because we got
        an interrupt signal, claim that the character came from the
        currently selected screen.

1992-03-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callproc.c (Fcall_process): Doc fix.

        * process.c [not defined (subprocesses)] (kill_buffer_processes):
        New dummy version of this function.
        * buffer.c (Fkill_buffer): Removed '#ifdef subprocesses'
        protection from the call to kill_buffer_processes; this is safe
        whether or not we actually have subprocesses.

1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * m/pfa50.h: New file.
        * process.c (create_process, process_send_signal): Added changes
        for m/pfa50.h.
        * sysdep.c: same.
        * unexec.c: same.

1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * callproc.c (child_setup): Always put the child in its own
        process group.

1992-03-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * mem_limits.h (POINTER): Doc fix.

        * ralloc.c: Don't #include lisp.h and xterm.h; we no longer need
        to block input in critical sections.
        (r_alloc, r_alloc_free, r_re_alloc): Don't use BLOCK_INPUT and
        UNBLOCK_INPUT; these are no longer needed.
        (struct bp): Doc fix.

1992-03-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * ralloc.c (obtain): When deciding how many pages to request, take
        into account the amount of spare bytes at the end of the current
        page; let get be ROUNDUP (size - already_available), instead of
        ROUNDUP (size).
        (relinquish): Re-organized for clarity.

        * editfns.c (Fcurrent_time): Updated to return the current time's
        seconds split into two 16-bit integers (similar to the system used
        by file-attributes), and the milliseconds.

1992-03-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)

        * process.c (Faccept_process_output): Add new optional argument
        TIMEOUT-MSECS, and return non-nil iff we actually got some input
        from the process(es).
        (wait_reading_process_input): Make return value indicate whether
        we got some input from the specified process, when read_kbd is a
        process, or from any process when read_kbd isn't particular.

        * indent.c (Fmove_to_column): Pass the correct number of arguments
        to Findent_to.

        * eval.c (Ffuncall): If a subr is asking for too many arguments,
        abort instead of printing an error message; this is an internal
        flaw in Emacs, and the subr cannot be called.

1992-03-06  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * doc.c (Fdocumentation, Fdocumentation_property): Take optional
        new arg to not pass results thru substitute-command-keys.

1992-03-05  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * unexmips.c (unexec): When setting up the data_section header,
        calculate the size of the section as "brk - data_start," not "brk
        - DATA_START".

1992-02-23  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * fileio.c: #include "systime.h".
        (Fcopy_file): Use the systime.h macros to copy the time to the new
        file.
        * ymakefile: Note that fileio.o depends on systime.h.

        * ymakefile (dispnew.o): Note that this depends on systerm.h and
        systime.h.
        (editfns.o, xterm.o, sysdep.o): Note that this depends on
        systime.h.
        (emacs.o, keyboard.o, process.o, sysdep.o): Note that these depend
        on systerm.h.

        * systerm.h: Expanded to handle getting and setting terminal
        parameters:
        (struct emacs_tty): New structure, which consolidates all of the
        old tty parameter structures.
        (EMACS_GET_TTY, EMACS_SET_TTY, EMACS_TTY_TABS_OK): New macros.
        * sysdep.c (TABS_OK): Definitions of this macro removed;
        EMACS_TTY_TABS_OK replaces it.
        (TERMINAL): Definitions removed; now we use struct emacs_tty.
        [VMS] (input_chan): Renamed to...
        (input_fd): and defined even when VMS isn't; in that case, we
        leave it initialized to zero, which is the input tty.  This allows
        us to use the EMACS_GET_TTY and EMACS_SET_TTY for both VMS and
        Unix.
        (discard_tty_input): Use struct emacs_tty and its macros instead
        of TERMINAL.  Replace some of conditional with a call to
        EMACS_GET_TTY.
        (child_setup_tty): Use struct emacs_tty and its macros instead of
        TERMINAL and conditionals.
        (old_gtty, old_ltchars, old_tchars, old_lmode): Replaced by...
        (old_tty): New variable.
        (lmode): Made conditional on BSD4_1, since it's only used by the
        BSD4_1 support code now.
        (init_sys_modes): Define tty to be a struct emacs_tty, not a
        TERMINAL.  Use macros to get and set parameters for VMS and
        Unices. Set lmode, tchars, and ltchars along with the rest of the
        tty state.
        (tabs_safe_p): Use EMACS_GET_TTY and EMACS_TTY_TABS_OK instead of
        conditionals.
        (reset_sys_modes): Use EMACS_SET_TTY to restore the settings from
        old_tty, instead of using hairy conditionals.

        * sysdep.c (get_screen_size): Neatened; now each system of
        reporting the screen size is separated from the rest.
        
        * systerm.h (EMACS_HAVE_TTY_PGRP, EMACS_GET_TTY_PGRP,
        EMACS_GET_TTY_PGRP): New macros to handle setting a tty's current
        process group.
        * sysdep.c (setpgrp_of_tty): Use the above, instead of
        conditionals.

        * sysdep.c: #include "systerm.h".
        #ifs that choose #include files moved from here...
        * systerm.h: to here.

        * sysdep.c [APOLLO]: We now undefine TIOCSTART not here but...
        * systerm.h: here.

        * sysdep.c [BROKEN_TIOCGETC]: We now undefine TIOCGETC not here but...
        * systerm.h: here.

        * sysdep.c [BROKEN_FIONREAD]: We now undefine FIONREAD and FASYNC
        not here but...
        * systerm.h: here.

        * process.c (process_send_signal): Steal 18.58's version of this,
        but incorporate the support for VMS signals.
            
        * syssignal.h (EMACS_KILLPG): New macro.
        * process.c (process_send_signal): Use it.
        * sysdep.c (sys_suspend): Use it.

        * syssignal.h (SIGCHLD): If we have SIGCLD and not SIGCHLD, define
        SIGCHLD as an alias for SIGCLD.
        * sysdep.c: Remove code for above.

        * sysdep.c (init_baud_rate): Rather than trying to maintain the
        illusion of an abstraction with the OSPEED and SETOSPEED macros,
        just use conditionalized code for each terminal kind.  This is the
        only place we ever need this functionality.
        (OSPEED, SETOSPEED): Definitions removed.

1992-02-22  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * sysdep.c: Moved definition of sigunblock macro to ...
        * syssignal.h: Here.

        * hftctl.c: #include <sys/uio.h> before #including <sys/tty.h>.
        (hfqry, hfskbd): Declare these functions as static before all uses.
        * unexaix.c (make_hdr, mark_x, copy_text_and_data, copy_sym):
        Declare as static before all uses.
        Remove extraneous semicolons from #ifdefs of COFF and XCOFF
        (unrelocate_symbols): cast the initializers of t_start and d_start
        to ulong.

        * s/template.h: Include a clause for the HAVE_TERMIO flag.

1992-02-21  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * keyboard.c (read_char): Don't clear Vquit_flag when we catch an
        interrupt and return a quit_char; this change (Mar 21 1991) is too
        large a change in functionality for the cleanliness it gains.

        * pwd.h: Renamed to vms-pwd.h, so that we don't get it by accident
        when we #include <pwd.h> with the `-I.' flag given to the
        compiler.
        * editfns.c [VMS]: Changed to include vms-pwd.h instead of pwd.h.
        * fileio.c [VMS]: Same.
        * filelock.c [VMS]: Same.
        * sysdep.c [VMS]: Same.

        * xrdb.c: Changed to #include "vms-pwd.h" if VMS is defined,
        instead of including <pwd.h> unconditionally.

        * window.c (Fset_window_display_table): Rearranged to make etags
        happy.

        * xterm.c (XTread_socket): Clear the meta flag from the keypress
        event before handing it to XLookupString.

1992-02-20  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * sysdep.c: No need to test #ifdef TIOCGETP before #undefing it.

1992-02-19  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * systime.h: New file.
        * dispnew.c: #include "systime.h" to get <time.h> or <sys/time.h>,
        whichever is appropriate, instead of using a conditional.
        (Fsleep_for, Fsit_for, Fsleep_for_millisecs): Use the systime.h
        macros instead of HAVE_TIMEVAL conditionals.
        * editfns.c: #include "systime.h" to get <time.h> or <sys/time.h>,
        whichever is appropriate, instead of using a conditional.
        * fileio.c: Same.
        * process.c: Same.
        * xterm.c: Same.
        (wait_reading_process_input): Use the systime.h macros.
        * sysdep.c: #include "systime.h" to get <time.h> or <sys/time.h>,
        whichever is appropriate, instead of using a conditional.

        * m/template.h: Add description of NO_SOCK_SIGIO.

        * sysdep.c (reset_sys_modes): Doc fix.

        * keyboard.c (sigfree, sigholdx, sigblockx, sigunblockx,
        sigpausex): Definitions moved to syssignal.h.

        * dispnew.c: Doc fix.

        * systerm.h: New file, to consolidate the system-dependent
        terminal-handling trash.
        * emacs.c: #include systerm.h.
        (main): Use systerm.h macros instead of conditionals.
        * dispnew.c: #include systerm.h.
        (update_screen): Use EMACS_OUTQSIZE instead of the direct ioctl.
        * keyboard.c: #include systerm.h to get the proper FIONREAD header
        files, instead of using conditional.

        * syssignal.h: Added copyright notice.

        * emacssignal.h: Renamed to syssignal.h, to be like sysdep.c.
        * data.c, keyboard.c, process.c, sysdep.c, ymakefile: Changed
        #include directives.

1992-02-15  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * m/intel386.h: Don't bother casting the argument to the signal
        function; the SIGTYPE code in config.emacs ought to take care of
        this.

        * buffer.c (record_buffer): Doc fix.

1992-02-13  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * s/iris3-6.h: #define HAVE_GETWD.

1992-02-11  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * window.c (Fwindow_at): Accept position as two arguments, not a
        cons of numbers.

        * window.c (scroll_command): Undo the Jan 31 change; do set the
        current buffer to the selected window's buffer.  A simple
        set-buffer will make these two different.

1992-02-10  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * callproc.c (Fcall_process): Clear synch_process_death and
        synch_process_retcode to zero before forking the process.

        * process.c (synch_process_death, synch_process_retcode): Don't
        declare them extern here.
        * process.h (synch_process_death, synch_process_retcode): Declare
        them extern here, along with synch_process_alive.

        * s/hpux.h: Define CLASH_DETECTION.

        * window.c (init_window_once): Don't pass any arguments to
        make_window.

        * keyboard.c (command_loop_1): Move the label directly_done out of
        the else block to just after the else block.  This shouldn't
        change the semantics of the code, but appears to avoid a compiler
        bug on SCO Unix V.3.2v2.

        * fileio.c (Fset_umask, Fumask): New functions.
        (syms_of_fileio): defsubr them.

        * undo.c (Fprimitive_undo): When undoing a deletion with the point
        before the deleted text, use Finsert_before_markers so that the
        mark will end up on the other side of the text, if it's in the
        area at all.

        * xdisp.c (redisplay): Properly compute TAB_OFFSET for compute_motion.

        * keyboard.c (command_loop_1): Don't check whether cursor is at
        edge of screen here.
        * dispnew.c (direct_output_forward_char): Check here, and return
        zero if it can't be done.  And compare the cursor position to the
        window boundaries, not the screen boundaries.

1992-02-05  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * screen.c (Fscreen_parameters): If the screen has a minibuffer
        window on another screen, return the window, instead of nil.
        (store_screen_param): If the value of the minibuffer parameter is
        a window, try to make it the surrogate minibuffer window.
        (Qminibuffer): New variable, to support above change.
        (syms_of_screen): initialize and staticpro it.

        * m/tad68k.h: New file.

        * fileio.c (Ffile_accessible_directory_p): New function.
        (syms_of_fileio): defsubr it.
        * callproc.c: #include <errno.h>.
        (child_setup):  Accept yet another argument, current_dir.
        Don't try to report an error here if current_dir is inaccessible;
        this function is called in a vforking process.  Just have the
        process exit with an error code.
        (Fcall_process): Make sure that the current directory is okay
        here, before we fork.  Pass the current_dir argument.
        * process.c (create_process): Same here.

        * callproc.c (Fcall_process): Don't assign into args[1] when nargs
        < 2.  Instead, use a new variable called infile.  Re-arranged
        logic which processes the BUFFER argument.

1992-02-03  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * fileio.c (Fexpand_file_name): Doc fix.

        * scroll.c (line_ins_del): Since we're calculating the array from
        end to beginning, make the indices go that way, and thus clearly
        get the right boundary.  This used to ignore the [0] element, and
        write in the [screen_height] element, which doesn't exist.

1992-02-03  Richard Stallman  (rms at mole.ai.mit.edu)

        * xdisp.c (redisplay, try_window_id): Special case for change
        at beginning of line, if using selective display.

1992-01-31  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * m/delta88k.h: Added USUAL-OPSYS information, for the
        config.emacs script to use.

        * window.c (scroll_command): Don't bother setting the current
        buffer to the selected window's buffer; this should always already
        be the case.  Add check just in case.

        * indent.c (compute_motion): Don't pack vpos and hpos into one int;
        use separate variables hpos/vpos and prev_hpos/prev_vpos.
        (vmotion): Use largest int as tovpos arg to compute_motion.

1992-01-30  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * window.c: #include "keyboard.h" to get the Qmode_line and
        Qvertical_split declarations.
        * ymakefile (window.o): Note that this depends on keyboard.h.

        * callproc.c (getenv_internal): Cast the pointer to the variable's
        value to a char *; elisp strings are unsigned char *'s.  And
        valuelen is an int *, not an int **.

        * scroll.c (do_scrolling): Document meaning of enable flag in
        temp_screen.

1992-01-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * m-orion105.h (C_DEBUG_SWITCH, LIBS_DEBUG): Defs deleted.

1992-01-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * m-iris4d.h (C_SWITCH_MACHINE): New definition.

1992-01-28  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * keyboard.h: Declare Vfunction_key_map.

        * keyboard.h: New file, for external declarations used in
        processing keyboard input and events.

        poll_suppress_count): Extern declarations moved to keyboard.h.
        * keyboard.c: #include "keyboard.h".
        (Qvscrollbar_par, Qvslider_part, Qvthumbup_part,
        Qvthumbdown_part, Qhscrollbar_part, Qhslider_part,
        Qhthumbleft_part, Qhthumbright_part): Moved declarations here from
        xfns.c, so they're with the other event heading symbols.
        * eval.c: #include "keyboard.h".
        * ymakefile (callint.o, keyboard.o, keymap.o, xfns.o, eval.o):
        Note that these depend on keyboard.h.

        * xfns.c: The above symbols aren't here any more.  #include
        "keyboard.h" to get them.
        (syms_of_xfns): Don't initialize or staticpro them.
        * keyboard.h: Added extern declarations for the above.
        * callint.c: #include "keyboard.h".

        * xfns.c (Vmouse_screen_part): Variable removed, no longer used.
        (syms_of_xfns): Changed accordingly.

        * xterm.c (Qmouse_moved): Variable removed, no longer used.
        (Qmouse_click, Qscrollbar_click): Removed.  These are now event
        types, in keyboard.c and keyboard.h; they're no longer used in
        this way.
        (Vmouse_window, Vmouse_screen_part): Extern declarations removed.
        (XTread_socket): Don't assign to Vmouse_window or
        Vmouse_screen_part.
        (syms_of_xterm): Changed accordingly.

        * keyboard.h (EVENT_HAS_PARAMETERS, EVENT_HEAD, EVENT_WINDOW,
        EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON, EVENT_WINDOW_POSN,
        EVENT_TIMESTAMP, EVENT_HEAD_UNMODIFIED, EVENT_HEAD_KIND): New
        macros to recognize and access events that have parameters, like
        mouse events.
        * keyboard.c (read_char, echo_char, Fmouse_click_p,
        read_key_sequence): Use them.
        * keymap.c: #include "keyboard.h".
        (access_keymap, store_in_keymap, Fsingle_key_description): Use the
        macros from keyboard.h.

        * keyboard.c (Qevent_kind): New symbol, naming the property of an event
        header where we put the event's type.
        (Qfunction_key, Qmouse_click, Qscrollbar_click): New symbols, used
        to tag different kinds of events.
        (Qevent_unmodified): New symbol, naming the property
        of an event header where we put an unmodified version of the event
        header.
        (modify_event_symbol): Take a new argument, SYMBOL_KIND, whose
        value should be put on the Qevent_kind property of each symbol we
        make.  Set the Qevent_unmodified property of each symbol we make.
        (make_lispy_event): Pass the appropriate SYMBOL_KIND argument to
        modify_event_symbol.
        (struct event_head, head_table): New tables, to simplify the
        initialization of some of the event heads.
        (syms_of_keyboard): Initialize and staticpro the symbols given in
        head_table, and put the Qevent_kind and Qevent_unmodified
        properties on them.  Initialize all of the new symbols listed
        above.

        * keyboard.c (lispy_function_keys, lispy_mouse_names): Renamed
        these from function_key_names and mouse_names, and moved them
        outside of make_lispy_event, since static doesn't work on all
        systems, and these can't be automatic.

1992-01-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * fileio.c (Fwrite_region): Remove Alliant conditional.
        * crt0.c: Conditionals for ALLIANT_2800.
        * m/alliant-2800.h: New file.
        * unexfx2800.c: New file.

        * s/template.h: Document the SIGTYPE macro.
        * s/bsd4-3.h: Define the SIGTYPE macro.

        * data.c (Fsymbol_value): Extract all the innards of this function
        into find_symbol_value, except the code which signals an error.
        (find_symbol_value): New function.
        * lisp.h (find_symbol_value): Declare it.
        * keymap.c (current_minor_maps): Use it, instead of a call to
        Fboundp and Fsymbol_value per every minor map, for every key
        sequence read.

        * xterm.c (x_make_screen_visible): Don't raise the window.  This
        causes the window to pop to the front every time a message
        appears, which isn't desirable.

        * screen.c (Fselect_screen, Fdelete_screen, Fset_mouse_position,
        Fmake_screen_visible, Fmake_screen_invisible, Ficonify_screen,
        Fdeiconify_screen, Fscreen_parameters, Fmodify_screen_parameters,
        Fset_screen_height, Fset_screen_width, Fset_screen_size,
        Fset_screen_position): Use SCREEN_IS_X macro instead of testing
        for output_x_window.
        * xfns.c (adjust_scrollbars, Fx_store_cut_buffer): Same.

1992-01-25  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * term.c (term_get_fkeys): New function.
        (term_init): Call term_get_fkeys.

1992-01-21  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * editfns.c (Ffollchar, Fprevchar): Renamed to Ffollowing_char and
        Fprevious_char, for consistency.  Renamed Sfollchar and Sprevchar
        too.
        (syms_of_editfns): Fixed defsubrs.
        * lisp.h (Ffollchar, Fprevchar): Renamed extern declarations as above.
        
        * editfns.c (Ffollowing_char): Return 0 at the end of the buffer,
        as advertised.  Doc fix.
        (Fprevious_char): Doc fix.

        * config.h-dist: Rearranged to define user parameters before
        including the machine and opsystem files, so the files can have
        conditionals on the parameters.

1992-01-15  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * keyboard.c (read_key_sequence): When expanding a function key
        recognized with Vfunction_key_map, don't scan the expansion for
        further function key sequences.

        * keyboard.c (Vfunction_key_map): Real declaration moved to
        keymap.c; this declaration made extern.
        (syms_of_keyboard): DEFVAR and initialization of Vfunction_key_map
        moved to keymap.c, since it should be initialized to a keymap, but
        we don't want to rely on Qkeymap being initialized now.
        * keymap.c (Vfunction_key_map): Variable moved here.
        (syms_of_keymap): DEFVAR and init here.

        * keymap.c (Fglobal_key_binding): Doc fix.

1992-01-16  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * m-delta88.h: New file.

        Set synch_process_death and synch_process_retcode.

1992-01-14  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * config.h-dist (SIGTYPE): New macro to help give signal handlers
        the correct type.
        * s/usg5-3.h (SIGTYPE): Define this to be void.
        * dispnew.c (window_change_signal): Declare this to return
        SIGTYPE.
        * emacs.c (fatal_error_signal): Same.
        * data.c (arith_error): Same.
        * process.c (create_process_1, send_process_trap,
        create_process_sigchld, sigchld_handler): Same.
        (create_process): Declare sigchld according to SIGTYPE.  This
        means we don't have to cast the return value of signal.
        * keyboard.c (input_poll_signal, interrupt_signal): Declare these
        to return SIGTYPE.
        (kbd_buffer_store_event): Include a forward declaration for
        interrupt_signal here.
        * sysdep.c (struct save_signal): Say the handler returns SIGTYPE
        instead of int.
        (save_signal_handlers): So we don't have to cast the return value
        from signal here.
        (sys_suspend): Declare oldsig according to SIGTYPE.
        (select): Declare old_trap using SIGTYPE.
        (select_alarm, wait_for_termination_signal): Declare these to
        return SIGTYPE.

        * emacs.c: #include <termios.h>, if we have it.
        (fatal_error_signal): If we have termios, use tcgetpgrp to get the
        terminal's process group.
        * process.c: If we have termios, #include <termios.h> instead of
        <termio.h>.
        (process_send_signal): If we have termios, use tcgetpgrp to get
        the terminal's process group.  Have gid default to the child's
        pid, to simplify the logic below.
        * sysdep.c (flush_pending_output): If we are using termios, make
        this function a no-op; since we're not in the tty's pgroup, we
        would get a SIGTTIN.

1992-01-13  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * config.h-dist: Removed MAINTAIN_ENVIRONMENT clause.
        * callproc.c: Removed support for MAINTAIN_ENVIRONMENT.
        (init_callproc): Use getenv instead of egetenv to initialize
        Vshell_file_name.
        * emacs.c (decode_env_path): Use getenv instead of egetenv 
        * lisp.h: Removed support for MAINTAIN_ENVIRONMENT.
        * process.c: Same.
        * ymakefile: Same.
        * dispnew.c (init_display): Call getenv instead of egetenv.

        * editfns.c (Fgetenv): Function moved...
        * callproc.c (Fgetenv): To here, and made to scan
        Vprocess_environment instead of using the usual C getenv function.
        (getenv_internal): New function.
        (egetenv): New function.
        * lisp.h: Added extern declaration for egetenv.
        * editfns.c (syms_of_editfns): Adjusted.
        * callproc.c (syms_of_callproc): Adjusted.

        * window.h (minibuf_prompt_width): Declare this extern here, after
        minibuf_prompt.
        minibuf.c: Don't extern declare it here.
        indent.c: As above.

        * dispnew.c (buffer_posn_from_coords): If there is a prompt in the
        minibuffer, account for its width when computing the buffer
        position.

        * Makefile (doall): Explicitly export CC to the xmakefile.

        * ymakefile: Use /* */ around comments; # confuses cpp.

        * ymakefile: Note that ralloc.o depends on mem_limits.h, xterm.h,
        and config.h.
        Note that vm-limit.o depends on mem_limits.h.

        * lread.c (read_escape): Return \a as '\007', not '\a'; the latter
        isn't portable, and this routine would have to be revised anyway
        to deal with anything other than ASCII.

        * keymap.c (current_minor_maps): Rewritten not to use
        function-local static variables, to accomodate DGUX.

        * xterm.h (UNBLOCK_INPUT): Replace "abort ()" with "(abort (),
        0)", to avoid type conflicts on odd systems like Ultrix.

        * xrdb.c: Include <sys/types.h>, and declare getuid to return uid_t.

        * xdisp.c (redisplay_window): Use SET_PT macro instead of
        assigning to point.
        insdel.c (insert_from_string): Same.

        * xterm.c (XTcursor_to): Declare it static at the function
        definition, as well as at the top of the file.
        (dumpglyphs): Removed declarations for buf and cp; these variables
        are never used.

        * lisp.h (NULL): Renamed to NILP, so as not to conflict with
        <stdio.h>, and <stddef.h>.  All callers changed; all
        #undefinitions of NULL removed.

1992-01-12  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * xdisp.c (message): #ifdef NO_ARG_ARRAY, make a local block to
        declare the explicit argument array.

        * config.h-dist: Instead of reaching the machine- and
        system-dependent files through symlinks, replace the strings 

1992-01-09  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

        * keyboard.c (stuff_buffered_input): Don't forget to increment
        kbd_fetch_ptr while looping through kbd_buffer.

1992-01-08  Jim Blandy  (jimb at occs.cs.oberlin.edu)

        * keyboard.c (read_avail_input): Don't forget to fill in the
        screen field in events read from the terminal.
        * sysdep.c (kbd_input_ast, read_input_waiting): Call
        kbd_buffer_store_event with a `struct input_event *', not a
        character or a Lisp_Object.

1991-12-21  Jim Blandy (jimb at occs.cs.oberlin.edu)

        * bytecode.c (docall): Don't remove protection from the arguments
        to Ffuncall.

1991-12-20  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (Vfunction_key_map): New variable.
        (read_key_sequence): Changed to recognize and substitute bindings
        in Vfunction_key_map at any point in the sequence, unless they
        conflict with ordinary bindings.
        (syms_of_keyboard): DEFVAR, document, and initialize
        Vfunction_key_map.

1991-12-19  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keymap.c (Vminor_mode_map_alist): New variable, to support
        keymaps for minor modes.
        (current_minor_maps, Fminor_mode_key_binding,
        Fcurrent_minor_mode_maps): New functions.
        (Fkey_binding): Rewritten to scan for minor mode bindings too.
        (syms_of_keymap): DEFVAR, document, and initialize
        Vminor_mode_map_alist, and defsubr the new Ffunctions.
        (describe_buffer_bindings): Describe the bindings established by
        minor modes too.
        * keyboard.c (follow_key): New function, to support...
        (read_key_sequence): Completely rewritten to handle scanning an
        arbitrary number of keymaps at a time.

        * keyboard.c (Fread_key_sequence): GCPRO keybuf, since it can hold
        lisp expressions while waiting for input.  Don't pass too many
        arguments to read_key_sequence.
        (command_loop_1): Don't pass too many arguments to read_key_sequence.

        * keyboard.c (add_command_key): New function; there are several
        places that add keys to this_command_keys, so we make one function
        to do the work.
        (read_char, Fexecute_extended_command): Call add_command_key
        instead of writing out its code again.
        (init_keyboard): Allocate this_command_keys according to
        this_command_keys_size.

        * lread.c (read1): Change comment to use `share-lib' instead of `etc'.

        docstring similarly.
        (Fsnarf_documentation): Use "../share-lib/" instead of "../etc/"
        to find doc file while dumping.
        * unexaix.c: Similar doc fix.

        * ymakefile (etcdir): Variable removed.
        (libsrc, archlib, sharelib): New variables, to take the place of
        etcdir.

1991-12-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * ymakefile (CFLAGS): Don't automatically include C_DEBUG_SWITCH
        in the value for CFLAGS; the configuration script will take care
        of choosing the debugging and optimization switches.

        (syms_of_abbrev): Define that variable.

1991-12-13  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * m/m-*.h: Since the m- is now redundant, renamed all files to
        remove it, and changed references within files.
        * s/s-*.h: Same business.

1991-12-11  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * config.h-dist (MULTI_SCREEN): Define this automatically when
        we're using a window system.

1991-12-09  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * m/m-*.h (i.e. all machine config files): Added USUAL-OPSYS
        comments to tell the configuration script what sort of operating
        system this machine typically runs.

        * config.h-dist (MScreenWidth, MScreenLength): Deleted; no longer
        used.

1991-12-08  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * editfns.c (Fcurrent_time): New function, to return the current
        time as a number, like the Unix time(3) function.  This might be
        fun to port.
        (syms_of_editfns): defsubr it.

1991-12-05  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        directory containing architecture-independent data files.
        (init_callproc): Initialize Vdata_directory from PATH_DATA, and
        make sure it exists.  Renamed execdir to tempdir, because we use
        it for both Vexec_directory and Vdata_directory.
        (syms_of_callproc): Doc fix for Vexec_directory, new DEFVAR_LISP
        for Vdata_directory.
        * paths.h-dist (PATH_DATA): New path macro, to initialize
        Vdata_directory.
        * doc.c (get_doc_string): Use Vdata_directory to find the
        docstrings, not Vexec_directory.
        * lisp.h (Vdata_directory): New extern declaration, for above
        users.
        * config.h-dist: Changed references to ../etc to ../share-lib.

        cast the type of the symbol name before passing it to error.

1991-12-02  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (make_lispy_movement): Move call to
        mouse_position_hook from here...
        (kbd_buffer_get_event): To here, for symmetry with non-movement
        events.

        * keyboard.c (kbd_buffer_get_event): Set Vlast_event_screen for
        mouse movements, too. 

1991-11-27  Jim Wilson  (wilson at wookumz.gnu.ai.mit.edu)

        * alloca.c (alloca): Add parens to make precedence clearer.

1991-11-26  Michael I Bushnell  (mib at geech.gnu.ai.mit.edu)

        * search.c: need to include sys/types.h because of recent mod to
        regex.h.

1991-11-25  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * bytecode.c: BYTE_CODE_METER and BYTE_CODE_SAFE undefined by default.
        (METER_CODE): Define same name whether metering or not.
        (BinsertN): New byte code.
        (Fbyte_code): Improve overflow/underflow error messages.

        * macros.c (Fend_kbd_macro): Callers fixed.

1991-11-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (cmd_error): If an error occurs before somebody has
        provided a screen to print it on, print it to stderr and exit
        Emacs.  Handle batch-mode errors with the same code.
        * lisp.h (Qexternal_debugging_ouput): New extern declaration, for
        use in cmd_error.

        * screen.c (Fscreen_pixel_size, Fset_screen_position): Doc fix.

        * window.c (Fwindow_at): Typecheck COORDINATES more thoroughly.

        * screen.c (read_mouse_position): Function deleted.
        (Fread_mouse_position): Renamed to Fmouse_position, and changed to
        use mouse_position_hook.
        (syms_of_screen): Adjusted accordingly.
        * xfns.c (x_read_mouse_position): Function deleted.

        * screen.h (SCREENP): The non-MULTI_SCREEN case used to say this
        was false for all objects, but it should be true for the terminal
        screen, so make its definition the same as in the MULTI_SCREEN
        case.

        * screen.h (SCREEN_LIVE_P): New predicate.
        (CHECK_LIVE_SCREEN): New type-checking macro.

        * dispnew.c (Fredraw_screen): Use CHECK_LIVE_SCREEN.
        * screen.c (Fscreen_root_window, Fscreen_selected_window,
        Fnext_screen, Fset_mouse_position, Frestore_screen_configuration,
        Fmake_screen_visible, Fmake_screen_invisible, Ficonify_screen,
        Fdeiconify_screen, Fscreen_visible_p, Fredirect_screen_focus,
        Fscreen_focus, Fmodify_screen_parameters, Fset_screen_height,
        Fset_screen_width, Fset_screen_size, Fset_screen_position,
        Fselect_screen): Use CHECK_LIVE_SCREEN.
        * window.c (Fwindow_at, Fcurrent_window_configuration): Use
        CHECK_LIVE_SCREEN.
        * xfns.c (Ffocus_screen, Fx_pixel_width, Fx_pixel_height): Use
        CHECK_LIVE_SCREEN.

        * screen.c (Fdelete_screen): Do nothing if SCREEN is already
        deleted.
        
        * screen.c (Qscreenp): Staticpro this symbol.

        * xfns.c (Fx_create_screen): Doc fix.

        * xfns.c (Fx_create_screen): Give the screen a minibuffer if the
        'minibuffer parameter is t or nil; nil is the default value for
        omitted parameters, and t is intuitive.

1991-11-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * eval.c (specbind): Check that the thing being bound is a symbol.
        (funcall_lambda): Signal an invalid-function error if the
        arguments are not all symbols.

1991-11-08  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * screen.c (Fselect_screen): Don't select dead screens.
        * print.c (print): Print dead screen objects starting with
        "#<dead screen".

        * keyboard.c (read_key_sequence): Make sure that the compound
        events actually have valid window fields.

        * window.c (next_screen_window): Function deleted; Fnext_window
        can now do its job properly.
        (window_from_coordinates, window_loop): Call Fnext_window instead
        of next_screen_window.

        * xdisp.c (redisplay): Don't clear out minibuffer windows in the
        midst of the screen loop here.  That's confusing.
        (redisplay_window): Since this needs special code to detect
        minibuffers anyway, put it here.  And clear all the lines of a
        multi-line minibuffer, not just the first one.

1991-11-07  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * screen.c (Fdelete_screen): When searching Vscreen_list for a new
        value for last_nonminibuf_screen, remember that the screens live
        in the cars of the list, not the cdrs.

        * xterm.c (x_make_screen_visible): Rearranged for clarity.

        * xdisp.c (echo_area_display): Rearranged for clarity.

1991-11-06  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * screen.c (next_screen, prev_screen): New meaning for MINI_SCREEN
        argument helps implement the behavior of Fnext_window.
        (Fnext_screen): Document the new behavior.

        * screen.c (make_minibuffer_screen): Do set has_minibuffer for
        minibuffer-only screens.
        (Fscreen_parameters): Correctly generate value of minibuffer
        parameter using SCREEN_HAS_MINIBUF and SCREEN_MINIBUF_ONLY_P.
        * screen.h (SCREEN_HAS_MINIBUF): New predicate.
        * dispnew.c (change_screen_size): Use it.
        * screen.c (Fdelete_screen): Use it.

        * screen.c (Vglobal_minibuffer_screen): Renamed
        Vdefault_minibuffer_screen to better describe its significance.
        (make_screen_without_minibuffer, syms_of_screen): Adjusted.
        * xfns.c (Fx_create_screen): Doc string adjusted.

        * xdisp.c (display_mode_line): Make the code which names the
        screen after the current buffer not depend on
        Vglobal_minibuffer_screen.
        * xterm.c (Vglobal_minibuffer_screen): Don't declare this extern
        here; it's never used.

1991-11-05  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * screen.c (Fdelete_screen): Document the fact that surrogate
        minibuffer screens may not be deleted.

        * screen.h (SCREEN_MINIBUF_ONLY_P): New predicate, true iff the
        screen's only window is a minibuffer, aka a "minibuffer screen" or
        a "minibuffer-only" screen.
        * dispnew.c (change_screen_size): Use it.
        * screen.c (Fselect_screen, next_screen, prev_screen,
        Fdelete_screen): Use it.
        * window.c (Fdisplay_buffer): Use it.

        * screen.c (next_screen, prev_screen): Make MINIBUF a lisp
        boolean, not a C boolean.
        (Fnext_screen, Fdelete_screen): Changed to fit.
        * window.c (Fnext_window, Fprevious_window): Changed to fit.

        * screen.c (make_screen_without_minibuffer): Error string improvement.

        * screen.c (syms_of_screen): Doc grammar fix for Vemacs_iconified.

        * screen.c (next_screen): Added some sanity checks, rewrote comments.

        * screen.h (Vglobal_minibuffer_screen): Don't declare this.  It
        shouldn't be used for anything but screen creation.
        * window.c (Fminibuffer_window): Vglobal_minibuffer_screen is not
        necessarily the screen containing the current minibuffer window.
        Also, call choose_minibuf_window; it does much of the work here.
        (Fnext_window): Used to insist on looping through all screens if
        Vglobal_minibuffer_screen was non-nil.  Now includes screen's
        minibuffer window according to MINIBUF, no matter what screen it's
        on, and ignores Vglobal_minibuffer_screen.  Loop termination logic
        cleaned up.  Clarified doc string.
        (Fprev_window): Same problems as Fnext_window, above.
        * screen.c (Vglobal_minibuffer_screen): Documentation rewritten to
        emphasize that it is only a parameter of the creation of
        minibufferless screens, and not an indication of where the
        minibuffer is.
        (prev_screen): Used to assume that Vglobal_minibuffer_screen was
        the only minibuffer-only screen, and would enter an infinite loop
        if Vglobal_minibuffer_screen was the only screen in the list.
        Rewritten to fix these problems.
        * minibuf.c (Vglobal_minibuffer_screen): Don't declare it extern
        here; it's not used.

        * editfns.c (Fmessage): Don't call Fmake_screen_visible here.
        * xdisp.c (message, message1): Call it here, so that Emacs C
        functions like Fy_or_n_p make the screen visible too.

1991-11-04  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (readable_events): If EVENT_QUEUES_EMPTY, we can
        short-circuit and say no.  Otherwise, if do_mouse_tracking, we can
        short-circuit and say yes.  These things let us scan the event
        queue less often.

        * termhooks.h (mouse_tracking_enable_hook): Replaced by...
        (mouse_moved, mouse_position_hook): It turns out that it is
        possible and no less efficient simply to tell Emacs if the mouse
        has moved since last noticed, and let it ask for the current mouse
        position; X's pointer motion hints are a cool thing.
        * term.c (mouse_tracking_enable_hook): Replaced by...
        (mouse_position_hook): New, simpler interface.
        * keyboard.c (struct movement, movement_buf, movement_ptr):
        Replaced by...
        (mouse_moved): This flag, to be used in conjuction with
        mouse_position_hook.
        (EVENT_QUEUES_EMPTY): Adjusted to use mouse_moved instead of
        movement_buf and movement_ptr.
        (tracking_off, Ftrack_mouse): Don't call mouse_tracking_enable
        hook.
        (note_mouse_position): Moved to xterm.c.
        (get_mouse_position): Replaced by mouse_position_hook.
        (make_lispy_event): Movement event generation code moved out to a
        separate function...
        (make_lispy_movement): Create a mouse movement event for the
        current mouse position.  Use mouse_position_hook instead of
        get_mouse_position.  Added static declaration for this above...
        (kbd_buffer_get_event): Use mouse_moved instead of movement_buf
        and movement_ptr.  Call make_lispy_movement instead of
        make_lispy_event.
        (init_keyboard): Initialize do_mouse_tracking.  Don't init
        movement_ptr and movement_buf.
        * xterm.h (STANDARD_EVENT_SET): Add PointerMotionMask and
        PointerMotionHintMask to the set.
        * xterm.c (pixel_to_glyph_translation): Renamed to
        pixel_to_glyph_coords, made static, simplified to take advantage
        of constant-size characters, and extended to return the bounding
        rectangle of the glyph returned.
        (construct_mouse_click): The 'button' field of a button event is
        the button number, not a mask; convert it to a mask before
        frobbing x_mouse_grabbed.  Call pixel_to_glyph_coords properly.
        (last_mouse_screen, last_mouse_glyph): New variables, to keep
        track of when the pointer has moved to a different glyph.
        (note_mouse_position): Moved here from keyboard.c and made static.
        Check if the new mouse position is over a new glyph.  If it is,
        set mouse_moved flag; otherwise, call XQueryPointer to get the
        next motion event.
        (XTmouse_tracking_enable): No longer needed, since pointer motion
        hints let us implement the simpler mouse position hook.
        (XTmouse_position): New hook.  Call XQueryPointer to get the
        current mouse position and request notification about the next
        mouse movement.  Clear the mouse_moved flag.
        (pixel_to_glyph_coords, construct_mouse_click,
        note_mouse_position, XTmouse_position): Put these all on the same
        page.
        (XTread_socket): case MotionNotify, call note_mouse_position with
        the right args; don't call pixel_to_glyph_translation.
        (x_term_init): Set mouse_position_hook instead of
        mouse_tracking_enable_hook.

1991-10-31  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * xdisp.c (redisplay_window): When trying to avoid starting
        display at the end of the buffer: check that startp < ZV, not
        startp <= ZV.

1991-10-29  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * xterm.c (x_do_pending_expose, XTmouse_tracking_enable): Use
        SCREEN_IS_X instead of testing output_method directly.

1991-10-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * xdisp.c (redisplay): In the single-screen optimization, always
        update the minibuffer's screen as well as the selected screen, no
        matter what the echo_area_glyphs are.  This makes sure that
        messages get cleared after a keystroke.

1991-10-25  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * callint.c (Finteractive): Doc fix.

        * xterm.c (XTmouse_tracking_enable): Block input while changing
        the screens' input selection masks.

        * window.c (change_window_height): If the window being resized is
        the only window of the screen, no size change is possible; make
        the delta be zero.  Exit without "changing" the sizes of any
        windows if the delta is zero.

        * alloc.c: Don't bother to include xterm.h.
        (Fgarbage_collect): Don't bother to BLOCK_INPUT here,
        since we don't cons in the input handler.

1991-10-21  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * window.c (init_window_once): Set last_nonminibuf_screen to the
        initial terminal screen, so that poor Fdisplay_buffer doesn't try
        to create a new screen on a terminal.

1991-10-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * m-intel386.h (signal): Optionally don't define it.
        * s-isc2-2.h (DONT_DEFINE_SIGNAL): Define this.

1991-10-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * scroll.c (line_ins_del): Don't calculate costs off the end of mf
        and ov; use < in loop condition, not <=.

        * scroll.c (scroll_cost): Logic rearranged.

        * dispnew.c (change_screen_size): Change "SCREEN_IS_TERMCAP
        (screen) == output_termap" to "SCREEN_IS_TERMCAP (screen)"
        (window_change_signal): Use SCREEN_IS_TERMCAP predicate instead of
        testing output_method_directly.

1991-10-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * xterm.h (STANDARD_EVENT_SET): Include ButtonReleaseMask in
        STANDARD_EVENT_SET.
        * xterm.c (XTmouse_tracking_enable): Don't bother or'ing
        ButtonReleaseMask with the STANDARD_EVENT_SET.

        * dispnew.c (buffer_posn_from_coords): If the coordinates are off
        past the end of a line, return them as being *before* the newline,
        not after.

        * keyboard.c (kbd_buffer_get_event): Set input_pending after
        reading the event, no matter what sort of event it is - i.e., move
        the assignment to input_pending outside of the event lispifying
        conditional.

        * keyboard.c (note_mouse_position): Don't record a "new" mouse
        position unless it really differs from the last one returned.

        * keyboard.c (kbd_buffer_read_char): Renamed to
        kbd_buffer_get_event, for consistency with kbd_buffer_store_event.

        * window.c (Fwindow_at): modified to take the coordinates as a
        pair, not a two-element list, for ease of use and compatibility
        with events.  Make SCREEN argument second and optional.
        (Fcoordinates_in_window_p): Modified to take and return the
        coordinates as above, and to distinguish the right border as well
        as the mode line.
        (window_from_coordinates): Modified to distinguish the right
        border as well as the mode line.
        * lisp.h (Qmode_line, Qvertical_split): Declare this extern, from
        keyboard.c.
        * keyboard.c (make_lispy_event): Distinguish a window's right
        border from its text area.

        * window.c (coordinates_in_window): Make it static.

        * window.c (Flocate_window_from_coordinates): Renamed to
        Fwindow_at.
        (syms_of_window): Adjusted.
        * lisp.h: Adjusted to say so.

        * screen.c (Fcoordinates_in_window_p, window_from_coordinates,
        Flocate_window_from_coordinates): Functions moved to window.c.
        (syms_of_screen): Adjusted.
        * window.c (Fcoordinates_in_window_p, window_from_coordinates,
        Flocate_window_from_coordinates): Here they are.
        (syms_of_window): Adjusted.
        * lisp.h: Adjusted to say so.

1991-10-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * xterm.c (XTclear_end_of_line): This used to try to get the
        cursor out of the way by comparing the line being cleared with
        s->cursor_y, which is meaningless; it should have compared it with
        s->phys_cursor_y.  Changed to just mark the cursor as cleared if
        it's in the area we're clearing.

1991-10-13  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * m-intel386.h: Fix typo in #endif.

1991-10-12  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * callint.c (Fcall_interactively): Added new interactive spec 'K',
        for mouse clicks.  Added explanation to doc string.  Removed 'e'

        * keyboard.c (EVENT_QUEUES_EMPTY): Clarified comment.

1991-10-11  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (Qmode_line): New quoted symbol.
        (syms_of_keyboard): Initialize and staticpro it.
        (make_lispy_event): Use it to indicate when a mouse position is in
        a window's mode line.

        * xterm.c (XTread_socket): Consider the window to be resized if
        either the character or pixel dimensions have changed; this will
        catch font size changes.

1991-10-08  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * process.c (wait_reading_process_input): Removed all the
        exceptional condition stuff.  Emacs lacks any way to respond to
        such a state, and selecting for it without responding to it can make
        Emacs loop indefinitely.

        * xterm.c (XTread_socket, construct_mouse_click): Make sure that
        all enqueued events have their timestamp field set.
        * termhooks.h (struct input_event): Doc fix.
        * keyboard.c (last_event_timestamp): New variable.

        (Fx_own_selection, Fx_own_clipboard, Fx_get_selection,
        Fx_get_clipboard): Use last_event_timestamp instead of
        mouse_timestamp.

        * xdisp.c (redisplay): Don't pass extra arguments to
        update_screen.

        * keyboard.c (echo_truncate): Don't call echo here; this results
        in extraneous echoing of characters.
        (read_key_sequence): After calling echo_truncate, call echo_char
        to put the character we just read into the minibuffer, if
        appropriate.

        * keyboard.c (read_key_sequence): Removed unused argument
        no_redisplay.

        * xterm.c (x_display_bar_cursor): Declare this to be static void.

        * xterm.c (XTupdate_begin): Don't turn off the cursor.  This makes
        ugly flickering.  Instead, make it okay for XTins_del_lines to do
        so:
        * screen.h (struct screen): New field phys_cursor_glyph, keeping
        track of the glyph under the currently displayed cursor.  Since
        current_glyphs is sometimes inaccurate when we want to undraw the
        cursor (as when XTins_del_lines is called from do_scrolling), we
        can't always get the GLYPH from there.
        * xterm.c (x_draw_single_glyph): Take the glyph to draw as an
        argument, instead of taking it from the screen matrix.
        (x_display_box_cursor): Set and use s->phys_cursor_glyph.

        * ymakefile: Note that scroll.o and xmenu.o depend on screen.h.

        * keyboard.c (make_lispy_event): When building mouse movement
        event, use `m', not `event', dummy.

        * screen.c (Fscreen_parameters): Return the proper value for the
        'minibuffer parameter for minibuffer-only screens.

        constrain it to be within the visible region anyway.

        * xterm.c (XTwrite_glyphs): Instead of turning off the cursor
        before we write, just notice if we wrote over it.

        * xfns.c (x_decode_color): If a screen has two planes, then it is
        considered a color screen, and we should look up the color value.

        * ymakefile: Include xselect.o and xrdb.o in XOBJ even when
        HAVE_X_MENU is not defined.

        * fns.c (Fdelete): This used to be named Fdelq; Roland forgot to
        change the function name in his August 17 change.
        (syms_of_fns): defsubr Fdelete.

        * xfns.c (x_get_arg): Clean bad characters out of the screen name

        Bdowncase, BRgoto, BRgotoifnil, BRgotoifnonnil,
        BRgotoifnilelsepop, BRgotoifnonnilelsepop, BlistN, BconcatN): New
        byte codes.

        screen's name as the res_name.

        * xfns.c (x_make_screen_name): New function.
        (Fx_create_screen): Use x_get_arg to find screen name; if none has
        been specified, use x_make_screen_name; don't set the name again
        at the bottom.
        (x_get_arg): If SCREEN_NAME is nil, don't pass any class to
        Fx_get_resource.

        * xfns.c (x_get_arg, x_default_parameter): Take an extra argument
        TYPE, instead of encoding the type in the first letter of the
        property name.

        * buffer.c (Fkill_all_local_variables): Don't pass

        name-choosing work Fgenerate_new_buffer used to do.
        (Frename_buffer): Added second optional argument DISTINGUISH,
        which lets rename_buffer use generate-new-buffer-name if non-nil.
        Return the name the buffer was given.
        Do nothing if new name is already buffer's name.

        * xfns.c (Fx_get_resource): Take third argument CLASS, and require
        it to be specified whenever NAME is.
        All callers changed.

        depend on emacssignal.h.

        * window.c (Fselect_window): Modify surrogate minibuffer hack to
        make the minibuffer the selected window of the selected screen,
        AND select the minibuffer window's screen.
        * minibuf.c (read_minibuf): If the minibuffer window is on a
        different screen, save that screen's configuration too.

        * window.c (Fset_window_configuration): Use SCREEN_ accessor to
        get at a screen's root window.  Removed unused variable
        screen_to_select.
        (Fcurrent_window_configuration): Take an optional argument SCREEN.
        All callers changed.

        * window.c (auto_new_screen, Vauto_new_screen_function): Renamed
        to pop_up_screens and pop_up_screen_function, to be parallel with
        pop_up_windows.
        (display_buffer, syms_of_window): Changed appropriately.

        * fns.c (Fload_average) [DGUX]: Add code to support DGUX.

        * s-dgux.h, m-aviion.h: New files.

        * emacs.c (main) [POSIX_SIGNALS]: Call init_signals.

        * screen.c (Fdelete_screen): Update last_nonminibuf_screen if
        the screen it's currently pointing to gets deleted.

1991-07-22  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

        * screen.c (last_nonminibuf_screen): New variable.
        (Fselect_screen): Set last_nonminibuf_screen if appropriate.

1991-07-21  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

        * screen.h (last_nonminibuf_screen): Added declarations for new
        variable. 
        * minibuf.c (active_screen): Variable removed.
        (read_minibuf): Removed code to set and clear active_screen.
        * window.c (Fdisplay_buffer): Rewritten to use
        last_nonminibuf_screen.

        * screen.c (next_screen): Use SCREEN_ accessors instead of ->. 

        * window.c (Fdisplay_buffer): Removed reference to
        Fx_create_screen; we should rely on the auto-new-screen-function
        being set to something appropriate.

1991-07-21  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * keyboard.c (read_key_sequence): Restore the state of
        this_command_key_count along with the echoing state.

1991-07-20  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * xfns.c (Fx_synchronize): New function.
        (syms_of_xfns): defsubr it.

        * xdisp.c (redisplay): Don't turn on all_windows whenever we're
        using a separate minibuffer screen.  Even if there is some tweak
        necessary, this wasn't it.

        * process.c (status_notify): Do not forget to UNGCPRO.

        * screen.c (next_screen): Re-work logic to skip minibuffer-only
        screens so that it doesn't loop indefinitely, even when the only
        screen is a minibuffer-only screen.  Skip all screens that are
        only minibuffers, not just when they are the global minibuffer
        screen.

        * xdisp.c (message, message1): If the screen's message buffer
        is 0, toss the message; don't check the window system against
        the screen output_method.

1991-07-19  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (read_key_sequence): When we truncate the echo
        buffer because the user has switched screens, re-echo the
        character that caused the truncation.

        * lread.c (Fload): Change "source newer than ..." message not to
        refer to "libraries."  What is a "library," anyway?

        * window.c: #include "termhooks.h", and therefore <stdio.h> too.
        [MULTI_SCREEN] (Fselect_window): If the window being selected is
        the selected screen's minibuffer, but it lives on another screen,
        don't select that other screen - call the screen_rehighlight_hook
        instead.
        * termhooks.h (screen_rehighlight_hook): New hook, so that Emacs
        can shift the screen highlighting when needed.
        * term.c (screen_rehighlight_hook): Define it.
        * xterm.c (x_highlight_screen): New variable.
        (x_new_focus_screen): Move the rehighlighting code to...
        (XTscreen_rehighlight): New function.
        (x_display_bar_cursor, x_display_box_cursor): Use
        x_highlighted_screen instead of x_focus_screen.
        (x_term_init): Initialize screen_rehighlight_hook.
        * ymakefile: Make window.o depend on termhooks.h.

        * xfns.c (Fx_create_screen): Add mention of
        global-minibuffer-screen to docstring.
        * screen.c (make_screen_without_minibuffer): Improve error message
        displayed when Vglobal_minibuffer_screen is not a proper screen.

1991-07-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * config.h (PURESIZE): Definition moved to...
        * puresize.h: New file.
        (PURESIZE): Define this here.  This will allow people to change
        their pure storage allocation without having to recompile most of
        Emacs.
        * data.c: #include puresize.h, since CHECK_IMPURE needs PURESIZE.
        * alloc.c: #include puresize.h.
        [HAVE_SHM] (pure_size): New variable, so that XPNTR doesn't depend
        on PURESIZE.
        [HAVE_SHM] (init_alloc_once): Initialize pure_size here.
        * lisp.h [HAVE_SHM] (XPNTR): Defined in terms of pure_size,
        instead of PURESIZE.
        (pure_size): extern declaration added here.     
        * ymakefile: Added puresize.h to dependencies for alloc.c and
        data.c's .o files.

        * emacs.c (main): Doc fix for kludge to scan for -d.

1991-07-17  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * termhooks.h (struct input_event): #if 0'd out the definition for
        the screen_selected event type, and added the stipulation that the
        {non_,}ascii_keystroke events specify the screen they happen in.
        * xterm.c (x_new_focus_screen): Don't enqueue a screen_selected
        event.
        (XTread_socket): Calls to x_new_focus_screen in the EnterNotify,
        FocusIn, LeaveNotify, and FocusOut event code don't worry about
        enqueued events any more.
        * keyboard.c (new_selected_screen): Removed - see below.
        (Vlast_event_screen): New variable, visible to lisp code.
        (echo_length, echo_truncate): New functions.
        (readable_events): Removed screen_selected events from the set of
        things to skip.
        (kbd_buffer_store_event): Don't bother collapsing consecutive
        screen_selected events.
        (kbd_buffer_read_char): Don't process screen_selected events.
        (make_lispy_event): Re-arrange scrollbar events to put the window
        whose scrollbar was diddled right after the identifying symbol,
        for consistency.
        (read_key_sequence): Let the selected screen and the location of
        the event affect the keymap used to find its binding.
        (Fread_key_sequence): Update docstring.
        (syms_of_keyboard): Added DEFVAR_LISP for Vlast_event_screen.

1991-07-15  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)

        * screen.c (next_screen): If !mini_screen, only exclude the global
        minibuffer screen when the minibuffer is its only window.
        (Fnext_screen): Make the docstring clearer about what MINISCREEN
        means.

        * window.c (Fother_window): Indicate that it takes both a required
        and optional argument, instead of just one required.

1991-07-15  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * buffer.c (Fkill_buffer): Rehacked kill-buffer-hooks to use
        standard name kill-buffer-hook, and to use set_buffer_internal
        instead of Fset_buffer.  Use static variable containing symbol
        instead of intern.
        (syms_of_buffer, init_buffer_once): Qkill_buffer_hook =
        'kill-buffer-hook.

1991-07-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keymap.c (Fsingle_key_description): When describing a listy
        object, take the car to find the symbol that heads it, not the cdr.

        * dispnew.c (buffer_posn_from_coords): Pass col and line to
        compute_motion in the correct order.

        * keyboard.c (make_lispy_event): When calculating rows and columns
        for mouse clicks and movement events, don't forget to subtract the
        position of the window's top left corner before passing them to
        buffer_posn_from_coords.

        * screen.c (coordinates_in_window): Removed useless test for *y ==
        screen_height, and screen_height variable; this would be out of
        range of all the windows anyway.

        * xdisp.c (message1): Removed code to ignore messages before X has
        started up; this issue has hopefully been addressed by the
        condition-case in startup.el.

        * editfns.c (init_editfns): Make user_name char * instead of
        unsigned char *, since that's what most of the usages seem to
        want.  And when expanding ampersands in AMPERSAND_FULL_NAME mode,
        don't try to use user_name as a string; use Vuser_name.

        * minibuf.c (assoc_for_completion): New function.
        (do_completion): Use that to check for exact match.

        * minibuf.c (Ftry_completion):  Fix handling of matches aside from
        case.  If ignoring case, and all else equal, try to preserve the
        case of the characters in the input.

        * process.c (status_notify): GCPRO tail.

        * sysdep.c (creat_copy_attrs, rename_sans_version):  Always set
        protection to O:REWD when creating file.  Added new function
        rename_sans_version, which strips the version number from the target
        filename, renames the temporary file to this filename,  and then
        sets the file protection of this new file to be the same as the file
        being edited.

        * sysdep.c [VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
        (F_SETFL) [VMS]: Undefine this, to control conditionals.
        (getpwnam): Make `full' unsigned.
        (creat_copy_attrs): Add some casts.
        (sys_access): Change prvmask and CHECKPRIV to use bitfields.
        Add some casts, and make dummy an unsigned short int.
        Don't use & on constants.
        (vmserrstr): Add a cast.
        (sys_creat): Define va_count before this function.

1991-07-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * sysdep.c (sys_sleep, input_wait_timeout): Don't use & on constant.
        [VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
        (bzero, bcopy) [VMS]: Don't take address of `length'.

        * sysdep.c (sys_suspend): Cast value of `signal' to insulate from
        changed value type in sysV.3.

        * sysdep.c (child_setup_tty): Turn off erase & kill chars for BSD.

        * sysdep.c (discard_tty_input): Use TIOCFLUSH on Apollo.
        (init_sys_modes): Avoid TIOCSTART on Apollo.

        * sysdep.c: If HAVE_TERMIOS is not defined, define tcgetattr in
        terms of the TIOCGETP ioctl.
        (init_sys_modes): Handle VSUSP, V_DSUSP if HAVE_TCATTR.
        (discard_tty_input, init_baud_rate, child_setup_tty,
        init_sys_modes, tabs_safe_p, reset_sys_modes):
        Use tcgetattr, and if HAVE_TCATTR, use tcsetattr.

1991-07-13  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)

        * s-hpux8.h: New file.
        * fileio.c [HPUX8]: Don't include errnet.h.

        * unexhp9k800.c (unexec): Local variable i to avoid compiler bug?

        * sysdep.c (insque) [WRONG_NAME_INSQUE]: New function.
        * s-386ix.h (WRONG_NAME_INSQUE): Define it.

        * xdisp.c (message_buf_print): New variable.
        (message): Clear it here.
        * dispextern.h: Declare it here.
        * print.c (printchar, strout): Set it and test it here.

        * keyboard.c (command_loop_1): Don't clear last_command when start
        macro.

        * keyboard.c (read_command_char): Exit at eof if noninteractive.

        * indent.c (invalidate_current_column): New function.
        * editfns.c (Fwiden, Fnarrow_to_region): Call it.

        * process.c (create_process): Use O_NOCTTY whenever defined,
        unless USG.

        * process.c (Fprocess_send_eof): If using a pipe, close it.
        (close_process_descs): Check IN and OUT for nonzeroness. 

        * process.c (process_send_signal): Use interrupt chars
        to send certain signals to the process group.
        (TIOCGETC): Undefine this if it is not really usable.

        * sysdep.c (discard_tty_input): Do nothing if read_socket_hook.

        * xfns.c (x_set_mouse_color): Change the default pointer shapes to
        be closer to xterm and emacs 18.

        * xterm.c (x_focus_on_screen, x_unfocus_screen): These no longer
        call XSetInputFocus, because I think that the X-windows ICCCM
        says that only the window manager can do this sort of thing.

        * keyboard.c (read_char): When there is an unread command
        character, goto reread_first when this_command_key_count is zero,
        not when it is >= 0.
        (command_loop_1): Reset this_command_key_count only if there is no
        prefix argument.  This makes echoing of keystrokes work correctly.

1991-07-11  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * eval.c (Finteractive_p): Changed "! XTYPE (foo) == Lisp_Bar" to
        "XTYPE (foo) != bar".

1991-07-11  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * eval.c (apply1): Don't forget to UNGCPRO before returning.

        * xterm.c (XTupdate_begin): Undisplay the cursor here; do_scrolling
        will call XTins_del_lines when the screen matrix is inaccurate, so
        we cannot undisplay the cursor then, but do_scrolling is always
        called within an update.

1991-07-10  David J. MacKenzie  (djm at nutrimat)

        * termcap.c, tparam.c [!emacs, USG || STDC_HEADERS]: Define bcopy
        in terms of memcpy.

1991-07-09  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * scroll.c (do_scrolling): Use correct termination condition for
        loop that uses the glyph pointers for the deleted lines to fill in
        the inserted lines.

1991-07-08  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * editfns.c: Doc fix.

1991-07-03  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * dispnew.c (line_hash_code): Test m->highlight[vpos], not
        m->highlight.  All lines were getting hash codes of -1, because
        the highlight vector was never NULL.  Golly.

        * process.c (list_processes_1): Handle status of network streams.

1991-07-02  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * doc.c (Fdocumentation_property):
        Pass only strings to Fsubstitute_command_keys.

1991-07-02  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * editfns.c (init_editfns): If neither of the environment
        variables are set, DON'T set Vuser_name to Vuser_real_name; it's
        supposed to reflect the EFFECTIVE uid.
        Get the full name according to Vuser_name if it differs from
        Vuser_real_name, not if they are equal.
        And pass Vuser_name to getpwnam in that case instead of user_name,
        which might be 0.

        * lisp.h (RETURN_UNGCPRO): New macro.
    
        * bytecode.c (Fbyte_code): Do not remove GC protection from the
        stack when making a function call, because the caller is
        responsible for protecting the arguments to a MANY-arg'ed
        function.
        * eval.c (Fapply): If we use funcall_args, GCPRO it.
        And when we call Ffuncall with funcall_args, tell it the correct
        length of funcall_args, no matter which branch allocated it.
        (Ffuncall): Don't gcpro the arguments before calling
        Fgarbage_collect.
        (Feval): If we're calling a subr that takes MANY args, don't
        UNGCPRO until after we call the subr.
        (apply1, call0, call1, call2, call3): GCPRO the arg arrays passed
        to Ffuncall and Fapply.
        * callproc.c (Fcall_process, Fcall_process_region): Don't GCPRO
        the argument array.
        * editfns.c (Finsert, Finsert_before_markers): Don't GCPRO the
        argument array.  Added comment about when GCPROing is not needed.
        * mocklisp.c (Finsert_string): Don't GCPRO the argument array.

        * keyboard.c (init_keyboard): Handle SIGQUIT with interrupt_signal
        on any system that has HAVE_TERMIO, not just on USG systems.

1991-07-01  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * editfns.c (init_editfns): Test that user_name isn't 0.

1991-06-29  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * search.c: Doc fixes.

1991-06-28  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * keyboard.c (make_lispy_event): Let the posns of mouse clicks and
        mouse movements be nil when window_from_coordinates returns a
        NON-window, not when it returns a window.  Since posn is a lisp
        object, don't call make_number when consing up the event.
        Don't call make_number on the code member of the event.

        * keyboard.c (struct movement): Make the x, y, and time members
        Lisp_Objects, since it's easier to convert from a Lisp_Object than
        to.
        (note_mouse_position): Adjusted for the above.
        (make_lispy_event): Removed code to make Lisp_Objects for those
        members.

        * xterm.c (XTread_socket): When handling LeaveNotify events,
        remember that the focus member of the event is true when the
        receiving window now has the focus, not when it is losing it.
        * xfns.c (Ffocus_screen): Don't signal an error if SCREEN is
        already the focus screen.

1991-06-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * alloc.c (Fmake_rope): Use sizeof (GLYPH) instead of 2 to
        determine how large the string should be, and changed doc string
        to describe ropes as strings of glyphs, not just as strings of
        character pairs.
        (Frope_elt): Use sizeof (GLYPH) as the element size, instead of
        assuming that the elements are two bytes.
        * lisp.h (typedef GLYPH): Moved the definition from here...
        * config.h (typedef GLYPH): to here, so people can elect to get
        better performance if they don't want to use huge fonts.
        * xterm.c (dumpglyphs): Use XDrawImageString or
        XDrawImageString16, Depending on sizeof (GLYPH).
        
        * data.c (Fsetq_default): Call Fset_default to do the assignments,
        not plain Fset.

        The following changes were contributed by Jamie Zawinski
        <jwz@lucid.com>:

        * bytecode.c (Fbyte_code): BYTE_CODE_SAFE and BYTE_CODE_METER
        options added.
        Added Bmark, Bscan_buffer, Bset_mark to support error-checking for
        these obsolete bytecodes.
        Added Bunbind_all to support tail-call optimization (not yet
        implemented).
        Did NOT add the relative branch opcodes that were in the version
        of bytecode.c that Jamie sent.
        The branching bytecodes now only QUIT if they take the branch.
        Btemp_output_buffer_show, Bforward_char, Bforward_word,
        Bskip_chars_forward, Bskip_chars_backward, and Bforward_line
        passed the wrong number of arguments to their subrs. 
        Brem, Bbuffer_substring, Bdelete_region, Bnarrow_to_region,
        Bstringeqlsign, Bstringlss, Bequal, Bnthcdr, Bmember, Bassq,
        Bsetcar, and Bsetcdr passed arguments to the subr in the wrong
        order.

1991-06-25  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)

        * doc.c (Fdocumentation): Added a QUIT test to the loop that finds
        the symbol's function value.

1991-06-24  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * xterm.c (dumprectangle): Removed call to XFlushQueue here.

        * keyboard.c (command_loop_1): Call Fselect_screen to establish
        the new selected screen after the key sequence has been read, not
        at the top of the loop.  This way, a key sequence will happen in
        the screen it was typed at, or (to be more precise) the screen its
        last character was typed at.

        * keyboard.c (fast_read_one_key): Function deleted, since it had
        been #if 0'd out a long time ago.
        (command_loop_1): Support for fast_read_one_key removed.

        * eval.c (Ffuncall): Do GCPRO the arguments, contrary to the May
        16 change.  The convention appears to be that the MANY-arged
        callee must protect its own arguments.
        (Fapply): Don't protect funcall_args; they are the caller's
        responsibility.
        * bytecode.c (Fbyte_code): GCPRO the section of the stack *above*
        the args to Ffuncall, since it will be protected again once
        Ffuncall returns and therefore should stay valid.  If it is not
        protected, string relocation may make it invalid.
        * mocklisp.c (Finsert_string): GCPRO the arguments, since insert
        may cause a garbage collection.
        * editfns.c (Finsert, Finsert_before_markers): GCPRO the
        arguments, since insert may cause a garbage collection.
        * callproc.c (Fcall_process, Fcall_process_region): GCPRO the
        arguments, since insert may cause a garbage collection.

1991-06-20  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * buffer.h (struct buffer_text, struct buffer): small change to
        comments.

        * search.c (Fmatch_beginning, Fmatch_end): Fixed doc strings to
        indicate that non-regexp searches set these too.

        * window.c (Fset_window_start): If window is not the selected
        window, set windows_or_buffers_changed, so that redisplay will
        know that it should redisplay the window.

        * callint.c (Finteractive): Changed doc string to indicate that
        the interactive prompts are passed through format.

1991-06-20  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * buffer.c (syms_of_buffer): buffer-undo-list doc fix.

1991-06-11  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * data.c (Fsetq_default): Take multiple SYM, VAL args; syntax now
        parallel to setq.

1991-05-25  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * keyboard.c (kbd_buffer_read_char): Fix wait-for-input loop so
        that we always process/toss events we don't want to return.

        * screen.c (Fselect_screen): Call Ffocus_screen instead of
        x_new_selected_screen, which doesn't exist anymore.

        * xfns.c (Ffocus_screen): Declare the type of the SCREEN argument.

        * xfns.c (Fx_track_pointer): Function #if 0'd out - I don't think
        that this is a feature that we want.
        (syms_of_xfns): Elide the defsubr for the above.

        * xterm.c (x_mouse_screen, x_input_screen): Variable deleted,
        since all we really need is x_focus_screen; all other issues are
        the realm and responsibility of the window manager.
        (x_new_selected_screen): Renamed to x_new_focus_screen, and
        modified not to do thiogs inappropriate for signal handlers.
        (XTread_socket): Change the handling of EnterNotify, LeaveNotify,
        FocusOut and FocusIn events to use x_new_selected_screen, and
        ditched code that deals with x_mouse_screen and x_input_screen,
        since they don't exist anymore.
        (x_display_bar_cursor, x_display_box_cursor): Compare s with
        x_focus_screen to see what form the cursor should take.
        (x_destroy_window): Don't bother with x_input_screen.
        * xfns.c (x_mouse_screen): Removed extern declaration for this.
        (Fx_grab_pointer): Confine the pointer to x_focus_screen, not
        x_mouse_screen.  This is wrong, but will make emacs compile until
        this gets fixed.

1991-05-23  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (get_input_pending): Don't use trim_events; use
        readable_events instead.

        * keyboard.c (make_lispy_event): Remove case for window_sys_event,
        since that type of event doesn't exist anymore.

        * minibuf.c (Fcompleting_read): Document the backup-n argument.

        * dispnew.c (init_display): Don't declare alternate_display extern
        here.  I can't figure out what this feature is, and it's broken.
        * emacs.c (main): Don't test alternate_display and put its value
        in the environment.

1991-05-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (struct movement): Made .used an int instead of a
        char, since that's more likely to be stored atomically on SPARCS
        and similar machines. 

        * termhooks.h (struct input_event): Removed the window_sys_event,
        since it's not used anywhere.  Added screen_selected event type.
        The event handling code used to change the current buffer,
        selected window, and selected screen out from under running lisp
        code.  Now we wait for a more convenient time by enqueuing an
        event.
        * xterm.c (XTread_socket): When handling FocusIn events and
        EnterNotify events with the focus member set, enqueue a
        selected_screen event instead of calling x_new_selected_screen.
        * keyboard.c (trim_events): Function deleted; it is a bad idea to
        delete events based on the current tracking state, since tracking
        might be re-enabled later.
        (readable_events): New function which searches the input queue for
        readable events.
        (tracking_off): Call readable_events to see if we should
        redisplay.
        (kbd_buffer_read_char): Toss events that we are not interested in.
        This is a better place to do it than trim_events, since we know
        that do_mouse_tracking will not change.  Also, handle
        screen_selected events.
        (new_selected_screen): New variable, holding the screen which
        should become selected the next time through command_loop_1.
        (syms_of_keyboard): Initialize and staticpro new_selected_screen.
        (command_loop_1): If there is a new screen to be selected, do so.

1991-05-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * xdisp.c (message): Removed the if at the top that did not
        display messages if the current screen was a termcap screen and a
        window system will be used.  The change to startup.el on May 18,
        1991 replaces this.

        * ralloc.c (check_memory_limits): If the address returned by the
        allocator is not representable in a Lisp_Object, call memory_full
        instead of printing a very silly "warning" message.

1991-05-19  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * xterm.c (XTread_socket): Don't overwrite the end of the buffer
        with function keys.

        * keyboard.c (tracking_off): Update input_pending after reading
        all the input.
        * process.c: #include "screen.h".
        (wait_reading_process_input): Check if any screens have been newly
        mapped and need updating.
        * xterm.c (XTread_socket): Don't SET_SCREEN_GARBAGED when the
        screen is unmapped; do this when is mapped.
        (dumprectangle): Don't dump any data for garbaged screens.

1991-05-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * sysdep.c (init_sys_modes): Moved the clauses that set up
        interrupt-driven input out of the "if running on a terminal"
        clause, since these may need to be set up even when running on a
        window system.

1991-05-17  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * process.c (Fprocess_status): For network connections, return
        Qopen and Qclosed instead of Qrun and Qexit, as documented.

        * lread.c (read1): Removed code that treated numbers starting with
        a zero as octal.

1991-05-16  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * eval.c (Ffuncall): Don't gcpro the arguments; the caller
        protects them.
        (Fapply): Gcpro funcall_args, if we use them.

        * xterm.c (notice_mouse_movement): #if 0'd this function out.
        (XTread_socket): #if 0 the code that fakes motion events for
        moving in and out of windows.  Also, rearrange the MotionNotify
        case to give character rows and columns to note_mouse_position,
        not pixel x and y positions.  Don't deal with scrollbars here.
        * termhooks.h (struct input_event): Removed the mouse_movement
        event kind.
        * keyboard.c (movement_buf): A new buffer for mouse-movement events.
        This is hairier than you might think; see the comments for this
        and the comments for note_mouse_position and get_mouse_position
        for an explanation of why this is hairy.
        (movement_ptr): Where the event handler should store new mouse
        locations.
        (EVENT_QUEUES_EMPTY): New macro, to be used in the places that
        used to compare kbd_fetch_ptr to kbd_store_ptr to see if there
        were any events available; this macro tests the mouse movement
        buffer too.
        (Qmouse_movement): New symbol to head mouse movement events with.
        (trim_events): Mouse movement events are no longer in kbd_buffer,
        so don't try to trim them.
        (tracking_off, kbd_buffer_read_char, get_input_pending): Use
        EVENT_QUEUES_EMPTY.
        (get_mouse_position): New function to retrieve a mouse position
        from the buffer properly, no matter when the event-handling signal
        occurs.
        (kbd_buffer_read_char): If there is something in kbd_buffer, make
        an event for that; if there is a mouse movement, make an event for
        that; otherwise, the while loop lied.
        (make_lispy_event): Added code to produce mouse movement events.
        (init_keyboard): Clear the mouse movement buffer.
        (Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
        Qexited_window, Qexited_scrollbar): Removed extern declarations
        for these, since they're no longer generated.
        (syms_of_keyboard): Initialize and staticpro Qmouse_movement,
        remove DEFVAR_LISP for Vignore_mouse_events.

1991-05-14  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * lread.c (read1): Correctly parenthesize the shift when parsing
        octal numbers, and signal an error if we see a non-octal digit.

1991-05-13  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * keyboard.c (trim_events): New function, to remove uninteresting
        events from the input queue.
        (get_input_pending): Call trim_events before checking the queue,
        so as not to advertise input we don't care about.
        (Ftrack_mouse): A new function to enable mouse tracking for a
        block of code.
        (tracking_off): A function for unwind_protection; restore the
        mouse tracking state to what it was outside of the track-mouse
        (syms_of_keyboard): defsubr track-mouse.
        (make_lispy_event): Find the window io which the click occurred
        when processing mouse_click events, instead of trusting the window
        tree in the signal-handling code.  Include the buffer position in
        the click event.

        * xterm.c (construct_mouse_click): Return the click's screen, not
        its window, and don't bother updating Vmouse_window.  Calculate
        the row and column of text-area clicks using
        pixel_to_glyph_translation, since we know that those data
        structures are alive in signal handlers.

        * screen.c (window_from_coordinates,
        Flocate_window_from_coordinates): Moved these to window.c, since I
        need to be able to call them even if we don't have multi-screen
        support.
        (syms_of_screen): Removed defsubr for
        Flocate_window_from_coordinates.
        * window.c (window_from_coordinates, Flocate_window_from_coordinates):
        Here they are.
        (syms_of_window): Here is the defsubr.

        * keyboard.c (note_mouse_position): New function to enqueue
        mouse movement events properly.
        (current_movement_event): New variable, to support the above.  See
        its comment for more explanation.

        * termhooks.h (struct input_event): Change the .window member to
        .screen, make it a struct screen *, and indicate that those events
        which used to return    windows now return screens.  It is unsafe
        for the event reader to traverse the window structure, because it
        can be called by a signal handler.

1991-05-10  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * keyboard.c (Vignore_mouse_events): Variable deleted.
        (make_lispy_event): For mouse and scrollbar clicks, return the
        position as a pair of numbers, not a list of two numbers.

1991-05-09  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * keyboard.c (do_mouse_tracking): Define this variable, which
        controls whether kbd_buffer_read_char will ignore button up and
        mouse movement events.
        * termhooks.h: Declare do_mouse_tracking here.

        * xterm.h (STANDARD_EVENT_SET): New constant, giving the event
        mask all the windows use.

        * xfns.c (Vx_send_mouse_movement_events): Removed this variable;
        XTmouse_tracking_enable and do_mouse_tracking do its job better.
        (syms_of_xfns): Remove the DEFVAR_LISP for the above.
        (x_window): Don't ask for any pointer motion events or button
        release events by default; use the unmodified STANDARD_EVENT_MASK.
        The user will ask for them explicitly if he or she wants them.
        And don't ask for backing store.

        * xterm.c (XTmouse_tracking_enable): New function to
        request/unrequest detailed mouse tracking information of the
        server, and set the flag used by XTread_socket.
        (x_term_init): Set mouse_tracking_enable_hook to
        XTmouse_tracking_enable here.
        (XTread_socket): Handle mouse movement events by calling
        note_mouse_position.

        * xterm.c (XTread_socket): For MapNotify events, go ahead and set
        the screen's visible flag, so Expose events will work.  Clear the
        iconified flag.

        * editfns.c (Finsert_char): Return immediately if n <= 0, not just
        if n < 0, so that the `while' below does not become an infinite
        loop.

        * term.c (mouse_tracking_enable_hook): Added this variable to
        allow emacs to request that the window system start or stop
        detailed mouse tracking.
        * termhooks.h (mouse_tracking_enable_hook): Declare it here.

        * xfns.c: Declare the functions before initializing
        x_screen_parm_table to point to them.

        * xterm.c (XTread_socket): Don't send Qmapped_screen,
        Qunmapped_screen, Qexited_scrollbar, Qexited_window,
        Qredraw_screen - these are not features that we want to support.

1991-05-07  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * editfns.c (Finsert_char): Let strlen be the minimum of n and
        256, not the maximum, so we use an n-byte buffer when n < 256, and
        a 256-byte buffer many times when n > 256.

1991-05-05  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * keymap.c (Fkeymapp): Fixed docstring to give the right
        definition of a keymap.

1991-05-03  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * data.c (Fcompiled_function_p): New function.

1991-05-03  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * xfns.c (struct x_screen_parm_table): New type for recording
        information about screen parameters.
        (x_screen_parms): New table describing the existing parameters.
        (init_x_parm_symbols, x_set_screen_param): Use x_screen_parms
        instead of a large switch statement.
        (x_figure_window_size): Make the default case of the switch call
        abort instead of signalling an error, since window_prompting's
        value is internally generated.

1991-05-01  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)

        * keymap.c (describe_map_tree): GCPRO the maps variable;
        Fkey_description calls Fmapconcat, which eventually calls
        Ffuncall, which can garbage-collect.

1991-04-28  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * dispnew.c (buffer_posn_from_coords): Use the information in bufp
        to reduce the distance compute_motion must scan, when possible.

1991-04-27  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (syms_of_keyboard): Qtop_level is initialized and
        staticpro'd in syms_of_data too.  Don't staticpro (or initialize)
        it again here.

        * macros.c (syms_of_macros): Since executing-macro and
        executing-kbd-macro are actually the same variable, use
        DEFVAR_LISP_NOPRO for the second one so it doesn't get staticpro'd
        twice.

        * process.c (syms_of_process): Don't staticpro or initialize Qexit
        here, since syms_of_eval already does this and it's bad to
        staticpro something twice.
        (Qexit): Remove declaration here, so there will be a compilation
        error if someone rearranges eval.c without fixing the Qexit stuff.
        * eval.c (syms_of_eval): Add comment here to say that
        syms_of_process cares about Qexit too.

        * lread.c (init_obarray): Don't staticpro Vobarray, since the
        DEFVAR_LISP in syms_of_read takes care of that.

1991-04-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * window.c (save_window_save): Always get the selected window's
        value of point from its buffer, not just when it's also the
        current buffer.

        * lisp.h (Qdisabled): Declare this here so that the keys_of_*
        files can disable the commands they define.
        * casefiddle.c (keys_of_casefiddle): Make upcase-region and
        downcase-region disabled, by default.

1991-04-16  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * bytecode.c (PUSH):  Alliant can't be bothered to implement the
        preincrement operator right, so use a comma.

        * print.c (syms_of_print): staticpro Qexternal_debugging_output.

        * editfns.c (clip_to_bounds): No longer static - used in window.c.
        * window.c (unshow_buffer): Use clip_to_bounds to make sure we
        change point to something legal.

1991-04-14  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * sysdep.c: Changes in formatting and comments.

1991-04-12  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * editfns.c (Fbuffer_substring): Don't call make_string, because
        it may cause a compaction and move the buffer, and then copy the
        wrong data.

        * keyboard.c (read_char): Only GC if we've actually done enough
        consing since the last gc to make it worthwhile.

1991-04-11  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)

        * keymap.c (access_keymap): Canonicalize the order of the
        modifiers when you look up a symbol in a keymap, too.
        (where-is-internal): If the keymap in which we found the
        definition was reached by meta-prefix-char, replace it with the
        metized character.

        * eval.c (Fcondition_case): Initialize the `handler_list' member
        of the catchtag.

        * keyboard.c (read_char): reset recent_keys_index when it is
        greater than OR EQUAL to the number of elements in recent_keys,
        stupid.

        * keymap.c (access_keymap): When fetching the car of listy events,
        no need to call Fcar_safe - extract the car directly.
        * keyboard.c (read_key_sequence): Don't extract the car from listy
        events here since 1) it strips information that we need from the
        events, and 2) access_keymap will take care of that for us.

        * macros.c (Qexecute_kbd_macro): New variable, used by
        Fexecute_command.
        (syms_of_macros): Initialize and staticpro Qexecute_kbd_macro.
        * lisp.h: Add extern declaration for Qexecute_kbd_macro.
        * keyboard.c (Fcommand_execute): Add an entry to the command
        history for keyboard macros too.

        * xterm.c (XTread_socket): If we get a MappingNotify event whose
        request == MappingKeyboard, someone has changed the keyboard
        mapping, and we should get the new mapping with
        XRefreshKeyboardMapping.

1991-04-10  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)

        * commands.h: Declare last_command_char to be a Lisp_Object, not
        an integer (ack).

        * cmds.c (Fself_insert_command): If last_command_char is not an
        integer, beep.
        * minibuf.c (Fself_insert_and_exit): Same thing.

        * keyboard.c (format_modifiers): New function, factoring out code
        from modify_event_symbol and reorder_modifiers.
        (modify_event_symbol): Call format_modifiers instead of doing the
        work inline.
        (reorder_modifiers): New function to put the modifiers on a
        modified symbol in the canonical order.

        * keymap.c (modify_event_symbol): Prepend the modifiers so they
        appear in the canonical order: `M-C-S-U-'.
        (store_in_keymap): If IDX is a symbol, put the modifiers in the
        canonical order before storing.

1991-04-09  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keymap.c (Flocal_set_key, Fglobal_set_key): When checking types
        of arguments, allow KEYS to be a vector or string, not just a
        string.
        (keymap_table): New static function to replace duplicated code in
        access_keymap and store_in_keymap.
        (access_keymap): Use keymap_table.
        (store_in_keymap): Use keymap_table, and put non-character
        definitions in dense keymaps *after* the vector.

        * fileio.c (directory_file_name): Remove trailing slashes from
        single-letter names like "a/" too.  Let slen be the string length,
        not one less than the string length.

        * keyboard.c (Fset_input_mode): Don't complain that QUIT isn't an
        ASCII character if it is nil - it is an optional parameter.

        * keymap.c (Faccessible_keymaps): Use meta-characters in the key
        sequences returned, carefully making sure that the sequences still
        appear in order of increasing length.

1991-04-04  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * vmsfns.c (vms_trnlog): Increased size of str to 256 elements.
        (vms_symbol): Increased size of str to 1025 elements.

1991-03-24  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * dispnew.c (pixel_to_glyph_translation): Moved this function to
        xterm.c, since it is specific to X and only called by the X code.
        * xterm.c (pixel_to_glyph_translation): Here it is.

1991-03-22  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * s-usg5-4.h (DATA_SEG_BITS): Definition deleted.
        * m-intel386.h (DATA_SEG_BITS): Define here if USG5_4.

1991-03-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keymap.c (Faccessible_keymaps): Produce meta-characters in the
        key sequences instead of [meta-prefix-char CHAR] sequences.

1991-03-21  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keymap.c (Flookup_key): If KEY is a zero-length array, then
        return KEYMAP; this is more algebraically satisfying.

        * dispnew.c (Fsit_for): If the time to sit is zero and there is no
        input available, then return Qt, not Qnil.

        * keyboard.c (read_char): If a quit occurs and we return
        quit_char, clear Vquit_flag, so we don't end up returning it again
        and again...  All lisp code does this manually if they call
        read-char with quits inhibited, so it's the right thing to do.

1991-03-20  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (read_char): If there is still no input available
        after an auto-save, do a garbage-collection.

        * undo.c (truncate_undo_list): Always leave at least one undo
        record in the undo list.  And use sizeof (struct Lisp_Cons), etc.
        instead of 8, etc.

        * keyboard.c (read_char): When deciding whether to wrap
        recent_keys_index back to 0, compare it against
        sizeof (recent_keys)/sizeof(recent_keys[0]),
        not sizeof (recent_keys).
        (quit_char): This can't be anything but an ASCII character, so it
        shouldn't be a Lisp_Object.  The declaration's comment says why.
        (read_char, init_keyboard): Treat quit_char as an int now.
        (Fset_input_mode): As above, and signal an error if QUIT is not an
        ASCII character.

        * callint.c (Fprefix_numeric_value): Use XFASTINT to initialize
        val, not raw.

        * fileio.c (Fmake_symbolic_link): Don't expand FILENAME; this
        would make it impossible to make a link to a relative name.

1991-03-19  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)

        * keyboard.c (syms_of_keyboard): Removed the DEFVAR_BOOL for
        meta-flag.  This cannot be a lisp variable because we need to
        change the terminal settings whenever this flag changes.  Change
        this through set-input-mode instead.

1991-03-19  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

        * keyboard.c (read_avail_input): Raise SIGHUP if no input on AIX.

1991-03-19  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * keyboard.c (kbd_buffer_store_event, kbd_buffer_read_char,
        read_key_sequence, Fexecute_extended_command, Fset_input_mode,
        init_keyboard, syms_of_keyboard): Use XSET (var, Lisp_Int, exp)
        instead of XSETINT (var, exp) in those cases where var is not
        known to already be a Lisp_Int.
        * search.c (skip_chars): Same.
        * xterm.c (construct_mouse_click, XTread_socket): Same.
        * callint.c (Fprefix_numeric_value): Make sure to return a
        Lisp_Int even when RAW is a cons whose car is not a Lisp_Int.
        * process.c (sigchld_handler): When searching for a process whose
        pid is -1, make sure that the pid is an int first, since network
        streams are in Vprocess_alist too.

        * keyboard.c (syms_of_keyboard): Added DEFVAR_BOOL for
        meta-flag.  Emacs 18 had this, and I see no entry in the ChangeLog
        saying that it was purposefully removed.

1991-03-17  Jim Blandy  (jimb at geech.ai.mit.edu)

        * keymap.c (Fcopy_keymap, Faccessible_keymaps, describe_map,
        append_key): Minor typos and brainos corrected.

        * keyboard.c (read_char): Removed code to find the vector in a
        (kbd-macro . VECTOR) - style macro, since the macro is represented
        by the vector itself.
        (read_char_menu_prompt): Changed to correctly recognize the new 
        dense keymap structures.
        (read_key_sequence): Changed code that checks for keymapness to
        use get_keymap_1 instead of doing the indirection and keymapness
        testing itself.
        (Fcommand_execute): A keyboard macro is now a string or a vector.
        (Fexecute_extended_command): When expanding this_command_keys,
        remember that it is now an array of Lisp_Objects, not chars.

        * doc.c (Fdocumentation): Rearranged into a switch statement, and
        made vectors macros, not keymaps.

        * eval.c (Fcommandp): Removed code to recognize 
        (kbd-macro . VECTOR) as a command, and added code to recognize
        vectors as commands.
        * macros.c (Qkbd_macro): Variable deleted.
        (syms_of_macros): Initialization of Qkbd_macro removed.

1991-03-14  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * minibuf.c (keys_of_minibuf): Changed all calls to
        initial_define_lisp_key to calls to initial_define_key.

        * keymap.c (describe_map): Adjusted to handle the new style of
        keymap.

1991-03-14  Richard Stallman  (rms at mole.ai.mit.edu)

        * fileio.c (Fwrite_region): On VMS, don't try rewriting old version.

1991-03-14  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * keymap.c (Faccessible_keymaps): Adjusted to handle the new style
        of keymap.
        (Fwhere_is_internal): Handle the new-style of keymaps.
        Additionally, only check to see if a match is shadowed by a
        binding in the local keymap when LOCAL_KEYMAP is non-nil, instead
        of comparing elt against DEFINITION yet again.
        (describe_map_tree): Handle key sequences that are vectors, as
        well as those that are strings.

1991-03-13  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * commands.h, keymap.c (meta_map, control_x_map): Make these
        Lisp_Objects, not Lisp_Vectors.
        keymap.c (syms_of_keymap): Same.

        * keymap.c (Fuse_global_map): There is no longer any reason to
        insist that KEYMAP must be a dense keymap; delete the code that
        does so.

1991-03-12  Jim Blandy  (jimb at wookumz.ai.mit.edu)

        * commands.h, lisp.h: Changed global_map and current_global_map to
        be Lisp_Objects, not Lisp_Vectors.
        keyboard.c (read_key_sequence): Same.
        keymap.c (Fkey_binding, Fglobal_key_binding, Fglobal_set_key,
        Fuse_global_map, Fwhere_is_internal, describe_buffer_bindings,
        syms_of_keymap): Same.

        * keymap.c (Fdefine_key): Braino: increment idx and clear metized
        flag even when the element of the key sequence isn't a character.
        (Flookup_key): Fix same braino.

1991-03-10  Jim Blandy  (jimb at wookumz.ai.mit.edu)

        * keymap.c (get_keyelt): Use access_keymap to resolve indirect
        entries, instead of duplicating its code.
        (Fcopy_keymap): Handle the new keymap structure.

1991-03-09  Richard Stallman  (rms at mole.ai.mit.edu)

        * eval.c (struct catchtag): New field handlerlist.
        (internal_catch, internal_condition_case): Set that field.
        (unbind_catch): Use it.

1991-03-08  Richard Stallman  (rms at mole.ai.mit.edu)

        * m-intel386.h (signal): Maybe define if USG.

        * keyboard.c (echo_char): Don't have space at end of echobuf.

1991-03-07  Jim Blandy  (jimb at albert.ai.mit.edu)

        * keyboard.c (syms_of_keyboard): Initialize mouse_syms, instead of
        doing func_key_syms twice.  Don't deal with scrollbar_syms, since
        it doesn't exist.

1991-03-06  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * keymap.c (access_keymap, store_in_keymap): Changed to handle the
        new style of keymaps.

        * fns.c (Fassq, Fcopy_alist): Changed docstring to promise to
        ignore elements of LIST that are not conses.  See access_keymap
        and copy_keymap for a cheap excuse.

1991-03-06  Richard Stallman  (rms at mole.ai.mit.edu)

        * s-vms.h (DATA_START): Remove `+ 512'.

1991-03-05  Jim Blandy  (jimb at spiff.ai.mit.edu)

        * keymap.c (Fmake_keymap): Rewritten to construct the
        new dense keymap structure: (keymap VECTOR . ALIST).  Docstring
        adjusted accordingly.  This means that the keyboard macro
        stupidity (see Feb 27, keyboard.c) is no longer needed.

1991-03-03  Richard Stallman  (rms at mole.ai.mit.edu)

        * sysdep.c (MEMORY_IN_STRING_H): New compilation flag.
        * s-isc2-2.h: New file.

1991-02-27  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * macros.c (Qkbd_macro): New variable, to hold the symbol
        `kbd-macro', which we use to tag vector-style keyboard macros.
        (syms_of_macros): Initialize and staticpro Qkbd_macro.

        * eval.c (Fcommandp): Recognize the new keyboard macros.

        * keyboard.c (Fcommand_execute): A keyboard macro is now a string,
        or a cons whose car is the symbol `kbd-macro' and whose
        cdr is a vector of events; previously, macros were strings or
        vectors, but that makes it difficult to tell the difference
        between macros and dense keymaps.
        (read_char): Handle the new macros correctly, and re-allocate
        this_command_keys correctly.

1991-02-26  Richard Stallman  (rms at mole.ai.mit.edu)

        * s-vms.h (calloc): Define like malloc, etc.

1991-02-26  Jim Blandy  (jimb at spiff.ai.mit.edu)

        * xterm.c (XTread_socket): Move enter_timestamp outside of the
        function; static variables inside functions don't always work in
        Emacs.

        * editfns.c (in_accessible_range): Deleted - insufficently
        general.
        (clip_to_bounds): New function, much like in_accessible_range,
        except that the upper and lower bounds are arguments.
        (goto_char, save_restriction_restore): Rewritten to use
        clip_to_bounds instead of in_accessible_range.

1991-02-25  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * keymap.c (initial_define_lisp_key): Turn KEY into a Lisp_Int
        before passing it to store_in_keymap.

        * buffer.c (reset_buffer_local_variables): Don't try to initialize
        the buffer's mouse_map and function_key_map fields, since they
        don't exist anymore.

        * macro.c (kbd_macro_buffer, kbd_macro_ptr, kbd_macro_end): These
        are now all pointers to Lisp_Objects instead of chars.
        (Fend_kbd_macro): Use make_sequence.
        (store_kbd_macro_char): Argument c is now a Lisp_Object.  Change
        call to xrealloc to ask for Lisp_Objects instead of chars.  Set
        kbd_macro_end to the same place in the new buffer as it was in the
        old one, not to the end of the buffer.
        (Fexecute_kbd_macro): Allow MACRO to be a string or a vector.
        (syms_of_macros): Allocate Lisp_Objects instead of chars for
        kbd_macro_buffer.

        * alloc.c (make_sequence): New function, useful to keyboard.c and
        macro.c.
        * keyboard.c (Fread_key_sequence): Use make_sequence.
        (Fthis_command_keys): Use make_sequence.

1991-02-24  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * keymap.c (Fwhere_is): If the command can't be found, the message
        is now "foobie is not on any key.", instead of "... any keys.".

        * keyboard.c (input_poll_signal): Pass 0 to read_avail_input,
        instead of `&junk'.  Removed variable `junk'.
        (command_loop_1): Updated to handle the unified function key/mouse
        event/keystroke arrangement.
        (Finput_pending_p): Removed vestiges of code to handle
        unread_input_char value of -1, since this doesn't happen anymore.
        (read_char): Adapted to handle lispy events.
        (read_char_menu_prompt): Allocate `menu' buffer using alloca,
        instead of a variable-sized array, which is gcc-specific.
        (Frecent_keys): Return the most recent "keystrokes" as a vector,
        to accomodate lispy events.
        (Fset_input_mode): Accomodate non-characters as quit keys.  If
        this is a bad thing, init_sys_modes will tell us.
        (init_keyboard): this_command_keys is now an array of
        Lisp_Objects; adjust the amount of storage we request to hold it.
        Remember that quit_char can be any keystroke.
        (syms_of_keyboard): last_command_char, last_input_char, help_char,
        menu_prompt_more_char and meta_prefix_char are now DEFVAR_LISPs
        instead of DEFVAR_INTs.
        
1991-02-24  Richard Stallman  (rms at mole.ai.mit.edu)

        * process.c (wait_reading_process_input): Use NETCONN_P.

1991-02-23  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * keyboard.c: (recent_keys, this_command_keys,
        menu_prompt_more_char, help_char, last_command_char, quit_char,
        last_input_char): Changed to Lisp_Objects, so we can use function
        keys for them.
        (Vglobal_function_map): Variable deleted.
        (echo_char): Echo function keys too.  The argument C is now a
        Lisp_Object instead of a char.
        (Fread_key_sequence): Removed sludge to handle window events
        specially, and added sludge to handle sequences with
        non-characters in them.
        (classify_object): Elided, since this should go away soon.
        (read_key_sequence): Adapted to look up symbols in keymaps,
        just like characters.

1991-02-23  Richard Stallman  (rms at mole.ai.mit.edu)

        * process.c (send_process): Handle EAGAIN like EWOULDBLOCK.

1991-02-22  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * doc.c (substitute_command_keys): Call describe_map_tree with
        only three arguments, since the CHARTAB arg has been disposed of.

        * keymap.c (Fcurrent_global_map, Fuse_local_mouse_map): Functions
        deleted, since the mouse maps are no longer separate from the key
        maps.
        (append_key): New function, which handles tacking a single
        keystroke on the end of a key sequence, promoting strings to
        vectors when needed.
        (Faccessible_keymaps): Adjusted to return vectors for key
        sequences, when necessary.
        (Fkey_description): Removed stuff to handle mouse buttons and
        other things specially, since this work will go into
        Fsingle_key_description.
        (Fsingle_key_description): SIMPLIFIED to handle everything
        correctly!  Jeepers!
        (Fwhere_is_internal): Scan the assoc-list at the end of dense
        keymaps, and construct strings or vectors.
        (where_is_string, describe_buffer_bindings): Simplified by
        deleting code to handle mouse button bindings specially.
        (describe_map_tree): Removed CHARTAB argument; this was
        a kludge to print out mouse events nicely, and is no longer
        necessary.  Nobody was using it anyway.
        (describe_map): Removed ugly hack to handle mouse buttons
        specially, added code to describe alists on dense keymaps, and
        removed CHARTAB argument.
        (describe_alist): Made to handle bindings of symbols as well as
        characters.  Removed CHARTAB argument.
        (describe_vector): Removed CHARTAB argument, allocated KLUDGE
        outside of loop and GCPRO'd it.
        (syms_of_keymap): Remove last vestiges of Vglobal_mouse_map,
        Vmouse_button_names, Suse_local_mouse_map,
        Scurrent_local_mouse_map.

        * buffer.h (struct buffer): Removed mouse_map and function_key_map
        members, since they are now handled by the keymap element.

        * keyboard.c (syms_of_keyboard): Change initialization of
        meta_prefix_char, since it's now a Lisp_Object.

        * keymap.c (Fkeymapp): Rewrote this to use get_keymap_1; now it's
        a one-liner instead of a 13-liner.
        (DENSE_TABLE_SIZE): Created new constant for the # of lookup-style
        entries in a dense keymap, and the index of the map's assoc list.
        Used it where appropriate.
        (Fcopy_keymap): Notice that 129'th element in dense keymaps.
        (Fdefine_key, Flookup_key): Reworked to deal with vectors of
        symbols and characters as well as strings for key sequences.
        (meta_prefix_char): Changed from an int to a Lisp_Object.

1991-02-21  Richard Stallman  (rms at mole.ai.mit.edu)

        * fileio.c (report_file_error): Don't downcase "I/O".

1991-02-20  Jim Blandy  (jimb at geech.ai.mit.edu)

        * keymap.c (access_keymap): Allow IDX to be any sort of bindable
        event, and deal with the extended keymaps.  IDX is now a
        Lisp_Object instead of an int, obviously.
        (store_in_keymap): Allow IDX to be any sort of bindable event, and
        deal with the extended keymaps.  IDX is now a Lisp_Object.

        * xterm.c (construct_mouse_click): Add code to set the up_modifier
        bit for ButtonRelease events.

        * keyboard.c (kbd_buffer_store_event): Use XFASTINT and XSETINT to
        access event->code, since it's a Lisp_Object.
        (kbd_buffer_read_char): Golly, perhaps we should increment
        kbd_fetch_ptr to remove the event we just read from the queue.
        (modify_event_symbol): Stupid fixes: correctly look up unmodified
        symbols when cache entry has a modified symbol vector.  And, when
        first adding the modified symbol vector, copy the old slot value
        into it correctly.

1991-02-19  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * keyboard.c (command_loop_1): #if 0 the block of code which
        handles mouse events and other lispy events specially, since I
        hope it will go away soon.

        * dispnew.c (Fsleep_for_millisecs): Pass all four arguments to
        wait_reading_process_input, instead of just the first two.

        * process.c (wait_reading_process_input): Remove support for
        only waiting for mouse input, since that has been superceded.
        This removes X dependencies from process.c, and eliminates some
        references to code that should only exist when using X10.

        * keyboard.c (mouse_moved_symbol, redraw_screen_symbol,
        mapped_screen_symbol, unmapped_screen_symbol,
        exited_window_symbol, exited_scrollbar_symbol): Renamed to
        Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
        Qexited_window, Qexited_scrollbar, just as done in xterm.c.
        (classify_object): Removed code to look up a function key in the
        global and local function key keymaps, since this will be done
        more generally.
        (Fexecute_mouse_event): Elided this function with a #if 0;  I
        think it will go away once the more general keymap stuff is
        implemented, but I'm not sure.
        (syms_of_keyboard): Removed defsubr for Sexecute_mouse_event.
        (where_is_string, describe_buffer_bindings, syms_of_keymap):
        Elided code to handle mouse button bindings specially; I hope this
        will go away.

        * lread.c (syms_of_lread): Change defsubr for eval-buffer to
        defsubr for eval-current-buffer.

        * keymap.c (syms_of_keymap): defvar for Vglobal_function_map
        removed, since that variable has disappeared.

        * xterm.c (x_func_key_to_sym): Removed entirely, since we no
        longer convert X keycodes to symbols in this section of code.
        (x_convert_modifiers): New function to turn the X modifier bits
        into struct input_event modifier bits.
        (encode_mouse_button): removed, since this work isn't done here
        anymore.
        (Vx_send_mouse_movement_events): Add an extern declaration for
        this.

        * termhooks.h: Only define struct input_event if the module
        has previously #included lisp.h; this avoids forcing simple modules
        like cm.c to #include lisp.h.

        * term.c: #include "lisp.h" before #including "termhooks.h", since
        the latter uses Lisp_Objects now.

        * xfns.c (syms_of_xfns): Delete the defsubr for Sx_window_id,
        since Fx_window_id is gone.

        * xterm.c (construct_mouse_event): Construct a struct input_event
        instead of a lispy event.

        * screen.c (coordinates_in_window):  Added explanatory comment. 
        (window_from_coordinates): Change PART, whose returned values are
        dependent on X-windows, to be called MODELINE_P, with appropriate
        new return values.
        * xterm.c (notice_mouse_movement): Handle the X-windows dependent
        stuff that used to be in window_from_coordinates here instead.
        (XTread_socket): Modified to produce struct input_events
        instead of lispy events.

1991-02-18  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * termhooks.h: Added up_modifier to the enum for modifier bits;
        this bit will be applied to mouse events.
        (struct input_event): Changed specification of non_ascii_keystroke
        events to send the function key number instead of a symbol.
        * keyboard.c (modify_event_symbol): Re-arranged to work well
        with function key/mouse button numbers instead of symbols.
        And if (MODIFIERS & up_modifer), prepend "U-" to the name of the
        symbol being constructed.
        (make_lispy_event): Use the new modify_event_symbol.

        * xterm.c (notice_mouse_movement): Adjusted this function to
        work with a struct input_event instead of producing an
        s-expression.

        * xterm.c, xfns.c: Made all references to x_mouse_queue,
        x_expose_queue, and the functions which manipulate them
        conditional on having X10, since only X10 code ever places
        anything in these queues.

1991-02-15  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * termhooks.h: Define struct input_event, to represent input
        events while they sit in the keyboard input buffer.  Using lisp
        objects to represent input events is a bad idea because the
        routines which enqueue them can be called from signal handlers,
        and therefore should not cons.

        * keyboard.c: (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Change
        these to be of type `struct input_event *'.
        (kbd_buffer_store_event): Manipulate struct input_events instead
        of lisp objects.
        (make_lispy_event): New function, to construct a lisp-style event
        corresponding to a particular struct input_event.
        (modify_event_symbol): New function, to add modifier prefixes to a
        symbol, and look the new symbols up quickly if they've already
        been created.
        (kbd_buffer_read_char): Call make_lispy_event to turn the thing
        in the keyboard buffer into the form that read_char is expecting.
        (Qwith_modifier_keys): Define this new symbol variable.
        (syms_of_keyboard): Initialize and protect Qwith_modifier_keys.

        * xterm.c (init_input_symbols): Rearranged the code that produces
        the func_key_syms array.
        (x_func_key_to_sym): Simplified, since more will be handled in
        make_lispy_event.
        (XTread_socket): When handling KeyPress events, don't pass the
        state of the modifier keys to x_func_key_to_sym, since it doesn't
        care any more.

        * sysdep.c (kbd_input_ast, end_kbd_input, read_input_waiting):
        Rename kbd_buffer_store_char to kbd_buffer_store_event.

        * keyboard.c (stuff_buffered_input): Since the keyboard buffer
        holds lisp objects, only stuff entries that are Lisp_Ints, and
        XINT them before passing them to stuff_char.
        (kbd_buffer_store_char): Make this not a static function, since
        sysdep.c calls it.  And rename it kbd_buffer_store_event.

        * keyboard.c (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Made these
        variables static, to document the fact that they're only used
        within keyboard.c.

1991-02-13  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * xterm.c (init_input_symbols): remove the `xk-' prefix from all
        the function key symbols, since they're going to be used for
        function keys from all sorts of terminals, not just when running
        under X.

        * lread.c (read_escape): Removed support for mouse button escapes
        (\S-, \U-, \C- applied to digits), because they're being replaced
        by something more rational.

1991-02-09  Richard Stallman  (rms at mole.ai.mit.edu)

        * buffer.c: Doc fix.

        * sysdep.c (dup2): Rewrite of non-F_DUPFD case.

1991-02-08  Richard Stallman  (rms at mole.ai.mit.edu)

        * m-intel386.h (LOAD_AVE_CVT): Add extra parens.
        * s-usg5-4.h (LIBX11_SYSTEM): #undef it.

1991-02-07  Richard Stallman  (rms at mole.ai.mit.edu)

        * s-esix.h: New version from kayvan.
        Adds HAVE_X11 conditional, NEED_PTEM_H, USG_SYS_TIME, USE_UTIME,
        LIBS_DEBUG; removes #undef sigsetmask, LIBS_SYSTEM, ESIX, 
        MISSING_UTIMES.

1991-02-06  Richard Stallman  (rms at mole.ai.mit.edu)

        * process.c (Faccept_process_output): Second arg gives timeout.

1991-02-06  Jim Blandy  (jimb at geech.ai.mit.edu)

        * lread.c (read_escape): Added support for \S- and \U- escapes (for
        binding mouse buttons), and noted that \C- must work on digits.

        * xterm.c (init_input_symbols): Was mistakenly renamed
        init_inputs; named back.

        * xterm.c (construct_mouse_click, encode_mouse_button): Rewritten
        to build new-style mouse events.

        * dispnew.c (update_line): Write a zero into obody[olen] to make
        sure the lines in current_screen->glyphs remain terminated.
        * xdisp.c (display_string, display_text_line): Don't write off
        the end of the line and destroy the zero terminator when expanding
        a tab.

        * fns.c (Fy_or_n_p): Accept C-] (usually abort-recursive-edit) as
        well as C-g to quit.

1991-02-05  Jim Blandy  (jimb at geech.ai.mit.edu)

        * sysdep.c, s-aix3-1.h, s-hpux.h, s-iris3-5.h, s-iris3-6.h,
        s-irix3-3.h, s-rtu.h, s-sunos4-1.h, s-unipl5-0.h, s-unipl5-2.h,
        s-usg5-0.h, s-usg5-2-2.h, s-usg5-2.h, s-usg5-3.h, s-xenix.h:
        Globally replaced INTERRUPTABLE with INTERRUPTIBLE.

        * xterm.c (construct_mouse_event): Renamed to
        construct_mouse_click, since there are kinds of mouse events
        besides clicks (movement, for example).
        (XTread_socket): rename calls here.

        * xterm.c (mapped_screen_symbol, unmapped_screen_symbol,
        exited_scrollbar_symbol, exited_window_symbol,
        redraw_screen_symbol, mouse_moved_symbol): Renamed to
        Qmapped_screen, Qunmapped_screen, Qexited_scrollbar,
        Qexited_window, Qredraw_screen, Qmouse_moved, to agree with naming
        conventions elsewhere in Emacs.

        * xfns.c (text_part_sym, modeline_part_sym,
        vertical_scrollbar_sym, vertical_slider_sym, vertical_thumbup_sym,
        vertical_thumbdown_sym, horizontal_scrollbar_sym,
        horizontal_slider_sym, horizontal_thumbleft_sym,
        horizontal_thumbright_sym): Renamed to Qtext_part, Qmodeline_part,
        Qvscrollbar_part, Qvslider_part, Qvthumbup_part, Qvthumbdown_part,
        Qhscrollbar_part, Qhslider_part, Qhthumbleft_part,
        Qhthumbright_part, to agree with the naming conventions elsewhere
        in Emacs.

        * xterm.c (XTread_socket): While handling EnterNotify events,
        clear Vmouse_event here.
        (notice_mouse_movement): Don't clear it here.

1991-02-04  Richard Stallman  (rms at mole.ai.mit.edu)

        * s-sunos4-0.h: Renamed from s-sunos4.h.
        (read, write, open, close): Macro defs moved to s-sunos4-1.h.
        (INTERRUPTABLE_*): Likewise.
        * s-sunos4-1.h: New file.

1991-02-04  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * keymap.c (Vglobal_mouse_map, Vglobal_function_map): Variables
        removed in preparation for conversion to unified keymap format.
        (Fmake_keymap): Make vector keymaps with 129 entries; the last
        will be an assoc-list for looking up symbols.  Update docstring to
        describe 129'th element.
        (Fmake_sparse_keymap): Update docstring to say that you can bind
        symbols in these maps too.
        (Fkeymapp): Recognize 129-element vectors as keymaps, not
        128-element vectors.
        (get_keymap_1): wrong_type_argument can no longer return a new
        value supplied by the debugger; remove loop to support this.

        * xterm.c (XTread_socket): When handling EnterNotify events,
        enqueue fake mouse events iff Vx_send_mouse_movement_events !=
        Qnil.

        * xfns.c (Fx_window_id): Function removed; Fscreen_parameters
        already provides this information.

        * xterm.c (x_term_init): Cleaned up the code to get the host name,
        and removed fixed limit on host name length.

        * window.c (Fscroll_other_window): Don't explicitly save
        current_buffer and point; the save_excursion will take care of
        that anyway.

        * dispnew.c (safe_bcopy): Rewritten to handle overlapping regions
        with multiple calls to bcopy instead of a stupid copy loop.

        * xterm.c, xfns.c (Vscreen_part, Vx_send_movement_events): These
        variables renamed to Vmouse_screen_part,
        Vx_send_mouse_movement_events.

        * lread.c (Feval_buffer): function deleted.
        (Feval_current_buffer): Removed "#if 0 ... #endif" around this
        function.

1991-02-03  Richard Stallman  (rms at mole.ai.mit.edu)

        * Makefile, ymakefile (SHELL): Force use of sh.

        * s-usg5-4.h (USG5_4): Define it.
        (LOAD_AVE_*): Don't define them.
        * m-intel386.h (LOAD_AVE_*): Define, if USG5_4.

        * buffer.c (Fbuffer_local_variables): Omit slots with no names.

1991-02-03  Jim Blandy  (jimb at geech.ai.mit.edu)

        * xterm.c (x_term_init, init_input_symbols): Moved these to the
        bottom of the file, 1) to be consistent with the other files, and
        2) so it can initialize some variables I want.

1991-02-02  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * xterm.h: Added external declaration for x_focus_screen.

        * search.h: File deleted.
        * buffer.h: declare searchbuf here instead.

        * screen.c (Ffocus_screen, Funfocus_screen): Moved these functions
        to xfns.c, since they're x-specific.
        (syms_of_screen): Removed defsubr calls for above.
        * xfns.c (Ffocus_screen, Funfocus_screen): Here they are.
        (syms_of_xfns): The defsubrs are here now.

        * buffer.h (PT): Make this expand to an expression which is not an
        l-value, to prevent people from assigning to it.  If everyplace
        uses SET_PT, it will be easier to merge in the interval code.
        (point): Similar changes here.
        (SET_PT): This can no longer be written in terms of PT, so write
        out current_buffer->text.pt.

        * xterm.c (x_new_font): Rewritten to remove arbitrary limit on
        size of x_font_table.
        (x_font_table_size): Created new variable.
        (n_available_fonts, font_names, font_info, MAX_FONTS): Deleted
        these variables/macros.

        * dispnew.c (scroll_screen_lines): Instead of disabling the lines
        vacated by the scroll (i.e. zeroing enable), mark them as enabled
        but empty.

        * callint.c (Fcall_interactively): Move UNGCPRO down, so that
        stuff is protected while we build the command history entry and do
        the function call.

        * xterm.c (XTupdate_end): Turn cursor on, even if we don't
        currently have the focus.

        * minibuf.c (temp_echo_area_glyphs): Clear echo_area_glyphs and
        previous_echo_glyphs, so the message we're displaying will
        supercede any existing message.

        * keyboard.c: Removed external declaration of echo_area_glyphs,
        since it's declared in window.h.

1991-01-31  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * xterm.c (XRINGBELL): Pass 0 as the second argument to XBell;
        respect the user's preferences.

1991-01-30  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * xterm.c (x_draw_single_glyph): New function, created to simplify
        cursor drawing/undrawing.
        (x_display_box_cursor): Rewritten to properly handle the box
        cursor in its filled and hollow forms.
        * xterm.h (enum text_cursor_kinds): Added enum for the different
        kinds of cursors which might be displayed in a window.
        (struct x_display): added member `text_cursor_kind' which says
        which kind of cursor is currently being displayed in the window, so
        we can arrange to redraw it effectively.

        * keyboard.c (command_loop_1): When handling the forward_char
        command, don't let point move to the location after the end of the
        buffer.

        * keyboard.c (poll_suppress_count): Define this even if
        POLL_FOR_INPUT is not defined, because this makes lots of #ifdef
        clauses unnecessary, and doesn't hurt, because
        {start,stop}_polling become nops.

        * config.h, config.h-dist: Make these #include "system.h" and
        "machine.h", and let the config script link these appropriately,
        instead of using the machine-specific names and expecting the user
        to edit this file.

1991-01-29  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * window.c (Fdelete_window): sib is a Lisp_Object; treat it as
        such.

        * xterm.c (screen_unhighlight): When the focus leaves a screen,
        draw the cursor as a box instead of making it disappear entirely.

1991-01-29  Richard Stallman  (rms at mole.ai.mit.edu)

        * unexec.c (make_hdr) [TPIX]: Set f_hdr.f_nscns and f_thdr.f_scnptr.

        * sysdep.c [BROKEN_TIOCGWINSZ]: Undef TIOCGWINSZ.

        * process.c (wait_reading_process_input): Don't ignore
        a zero-length read on a network connection.  Do close it.

        * sysdep.c (hft_init, hft_reset): Pass &junk as arg to HFQERROR.
        Do nothing if not HFT.

1991-01-29  Jim Blandy  (jimb at albert.ai.mit.edu)

        * xfns.h: Created, to declare things defined in xfns.c.
        Declare Vx_send_movement_events.
        * xfns.c: #include "xfns.h".
        (Vx_send_movement_events): Define this variable.
        (syms_of_xfns): DEFVAR_LISP it.
        * xterm.c: #include "xfns.h".
        (XTread_socket): Place a mouse-moved event in the buffer iff
        Vx_send_movement_events says to.

1991-01-28  Jim Blandy  (jimb at geech.ai.mit.edu)

        * ymakefile: noted that callint.o depends on mocklisp.h,
        and dired.o on search.h.

        * environ.h: Deleted - its creation in the first place was misguided.
        callproc.h: Removed #include "environ.h", and added declarations
        for environ.h

        * buffer.c (syms_of_buffer): Add more detailed documentation to
        buffer-undo-list.

        * lisp.h (poll_suppress_count): Add external declaration for this here.

1991-01-28  Richard Stallman  (rms at mole.ai.mit.edu)

        * m-sun3-68881.h, m-sun3-fpa.h, m-sun3-soft.h: New files.

1991-01-27  Jim Blandy  (jimb at geech.ai.mit.edu)

        * lisp.h (struct handler): add poll_suppress_count member, so
        we can restore poll_suppress_count when we handle an error.
        * eval.c (struct catchtag): Add it here too, for throws.
        (internal_catch, Fcondition_case, internal_condition_case): Record
        the value of poll_suppress_count here in the handler and catch tag.
        (Fthrow, Fsignal): Restore it here.

1991-01-25  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * xterm.c (x_display_box_cursor): If we're undrawing the cursor by
        redrawing the character underneath it, draw according to that
        line's highlight, instead of assuming it's in the normal GC.

1991-01-25  Richard Stallmao  (rms at mole.ai.mit.edu)

        * buffer.h (PTR_CHAR_POS): Value was too small by 1.

1991-01-16  Richard Stallman  (rms at mole.ai.mit.edu)

        * doprnt.c (doprnt): Check for overflow in fmtcpy.

1991-01-16  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * window.c (Fdelete_window): If the deletee gives its space to its
        next sibling, that sibling needs to have its top/left side pulled
        back to where the deletee's is.

1991-01-15  Jim Blandy  (jimb at geech.ai.mit.edu)

        * doc.c (Fsnarf_documentation): handle attaching docstrings to
        bytecode objects too.

        * syntax.h (syntax_spec_code): make external declaration for this
        unsigned char to match the definition in syntax.c.

        * indent.c (compute_motion): added comments describing how it
        can be used.

1991-01-15  Richard Stallman  (rms at mole.ai.mit.edu)

        * process.c (create_process): Use SETUP_SLAVE_PTY if defined.

        * s-usg5-4.h (HAVE_PTYS, HAVE_SETSID): Defined.
        (HAVE_WAIT_HEADER, WAITTYPE, wait3, WRETCODE): New macros.

        (UNEXEC): Define it.
        (PURE_SEG_BITS, SHMKEY): Define only if CANNOT_DUMP.
        (LINKER): Override it.  Then add -bnodelcsect.

        * xfns.c (Fx_get_default): Try reversing XGetDefault args if it fails.

1991-01-13  Richard Stallman  (rms at mole.ai.mit.edu)

        * s-usg5-4.h (LOAD_AVE_CVT): Cast value to int.

        * keyboard.c (read_avail_input): Signal SIGHUP if FIONREAD fails.

        * ymakefile: Put tokens after #endif into comment.

        * filelock.c (lock_file_owner_name): Declare argument type.

1991-01-12  Richard Stallman  (rms at mole.ai.mit.edu)

        * s-irix3-3.h (HAVE_SYSVIPC): Defined.

1991-01-12  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * dispnew.c (buffer_posn_from_coords): compute_motion starting
        from bufp[y] instead of counting from the top of the window.

1991-01-11  Richard Mlynarik  (mly at pizza.ai.mit.edu)

        * window.c (window-configuration-p):  Needed.  Added.

1991-01-11  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * dispnew.c (buffer_posn_from_coords): Remember to deduce space
        for the line continuation markers and the window separators from
        the window width.

        * s-sunos4.h: read, write, open and close are interruptable.

1991-01-09  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * xterm.c, dispnew.c (pixel_to_char_translation): Renamed to
        pixel_to_glyph_translation, and rewritten.  Just get coordinates,
        don't return anything.
        (buffer_posn_from_coords): New function - given a window and
        co-ordinates on the screen, find the buffer position at those
        co-ordinates. 

1991-01-08  Jim Blandy  (jimb at geech.ai.mit.edu)

        * alloc.c (Fmake_byte_code): Flesh out docstring.

        * window.c (window_loop): pick the first window correctly, even
        when screen == 0.

        * dispnew.c (scroll_screen_lines): Don't forget to call
        update_begin at the top of the down-scrolling section.
        And rotate by amount, not -amount, in the up-scrolling section.

        * xterm.h (MAX_FONTS, x_font_table, n_fonts): Removed external
        declarations for these variables, since they're declared static in
        xterm.c and not used elsewhere.
        * xterm.c (MAX_FONTS): Moved definition of this to here from
        xterm.h.

        * xterm.c (x_new_font): If you can't find the requested font,
        return a code which indicates this, instead of calling abort.

1991-01-07  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * xdisp.c (redisplay, display_mode_line): To test
        Vglobal_minibuffer_screen for validity, you must check that its
        type is Lisp_Screen; comparing it to Qnil isn't good enough.

        * screen.c (syms_of_screen): Initialize Vglobal_minibuffer_screen
        to Qnil; otherwise, it inhibits decent redisplay (is that another
        bug?)

        * dispnew.c (init_display): Make sure that the standard input is a
        terminal here.
        * emacs.c (main): Not here, since we don't know yet if we want to
        use a window system of some sort.

        * xfns.c (x_make_gc): Delete code to support default_face and
        highlight_face, since they're part of the interval code, and
        shouldn't be installed yet.

        * dispnew.c (init_display): calculate_costs expects a screen
        parameter; pass selected_screen, instead of nothing.

        * search.c (Freplace_match): Protect STRING.
        * process.c (run_filter): New function.
        (read_process_output, exec_sentinel): Use run_filter to call the
        process's filter function.

        * sysdep.c (init_sys_modes): Turn off VSUSP and V_DSUSP if they exist.
        Only on a MIPS.

        * xselect.c (x_answer_selection_request): For incremental, set
        format to 32 and send only 1 element.  Pass the address of size,
        not size itself.
        (x_selection_arrival): For incremental, delete the property
        containing the size of the transfer.  This generates a
        PropertyNotify to the owner, starting the exchange.

        * xrdb.c (get_user_app): Pass correct number of parameters to
        sprintf.

        * xfns.c (x_window): Don't use backing store or saveunders; they
        seem to slow down suns.
        (x_icon): Set the InputHint to the window manager to False.
        (x_make_gc): Initialize gc_values.line_width to zero before
        creating the normal video GC, since it uses it.  And set the
        default_face and hilite_face gcs here.
        (install_vertical_scrollbar): Add 2 to thumbdown y position, and
        don't add ibw.

        * insdel.c (insert, del_range): Use SET_PT rather than assigning
        point directly.
        * window.c (Fselect_window): Here too.

        * xdisp.c (redisplay_all_windows): removed static declaration for
        this nonexistent function.

1991-01-04  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * window.c (window_loop): neatened up.  MINI being non-zero now
        makes it recognize active minibuffer windows.  Iterates properly
        over multiple screens when asked nicely.
        (Fget_lru_window, Fget_largest_window): SCREENS arguments are now
        declared as a Lisp_Object, and documented.
        (Fget_buffer_window): SCREENS argument is now documented.
        (Fdelete_other_windows): Delete other windows on the argument
        window's screen, not the current screen.

        * screen.c (window_from_coordinates): Changed other reference to
        Fnext_window to use next_screen_window; see below.

        * window.c (Fnext_window, Fprevious_window): Accept non-nil, non-t
        values for mini, and don't turn off all-screens when mini is t but
        there is no global minibuffer screen.  Remove screen_{root,mini}
        variables.
        (Fother_window): Added second argument all_screens.

        * undo.c (record_delete): Removed dead variable llength.

        * data.c (Qkeyp, Fkeyp): Removed these and supporting code.
        * keymap.c (Fsingle_key_description): Report an error instead of
        calling wrong_type_argument.
        * lisp.h (Qkeyp): Removed external declaration for this.

        * scroll.c (do_scrolling): Use correct limits on loop to clear
        lines just inserted--old version lost a line.

        * screen.c: #ifdef HAVE_X_WINDOWS, #include xterm.h
        (Ffocus_screen, Funfocus_screen): use Joe's new definitions, and
        only define these functions ifdef HAVE_X_WINDOWS.
        (window_from_coordinates): use next_screen_window instead of
        Fnext_window, so that global minibuffers work.

        * lread.c (syms_of_read): Don't forget to defsubr
        read-char-exclusive.

        * lisp.h (Fscreenp, Fselect_screen, Ffocus_screen,
        Funfocus_screen, Fselected_screen, Fwindow_screen,
        Fscreen_root_window, Fscreen_selected_window, Fscreen_list,
        Fnext_screen, Fdelete_screen, Fread_mouse_position,
        Fset_mouse_position, Fmake_screen_visible, Fmake_screen_invisible,
        Ficonify_screen, Fdeiconify_screen, Fscreen_visible_p,
        Fvisible_screen_list, Fscreen_parameters,
        Fmodify_screen_parameters, Fscreen_pixel_size, Fscreen_height,
        Fscreen_width, Fset_screen_height, Fset_screen_width,
        Fset_screen_size, Fset_screen_position, Fcoordinates_in_window_p,
        Flocate_window_from_coordinates, Frubber_band_rectangle): added
        extern declarations for all these.

        * lisp.h (Qscreenp): added an extern declaration for this.

        * lisp.h (DBL_DIG): Added constant for the maximum number of
        decimal digits a float could print to.  Used in print.c.

        mouse and window system events too.
        (Fsingle_key_description): signal an error if obj is not a key.

        * data.c (Fkeyp, Qkeyp): Added predicate to recognize things which
        can be bound - this includes keys, symbols (for function keys and
        window system events), and conses (for mouse events).
        * lisp.h (Qkeyp): Added external declaration for this.

        * keyboard.c (Frecursive_edit): Don't specbind the standard IO here.
        (recursive_edit_1): Do it here, and don't forgot to unbind_to.

        (command_loop_1): Reset no_redisplay after mouse commands.

        (classify_object): Place the object in read_key_sequence_cmd.

        (Fread_key_sequence): recognize that when read_key_sequence
        returns -1 or -2, it's a mouse event or window system event.

1991-01-01  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * fileio.c (Fwrite_region): We should dereference GPT_ADDR[-1]
        before comparing it to '\n' for VMS cruft.
        (Fdo_auto_save): Don't call run-hooks before it's defined.  This
        only happens before emacs is dumped, when loading inc-vers.el.

        * eval.c (Fsignal): TOTALLY_UNBLOCK_INPUT here.
        (error): Not here.

        (Feval): We use argvals[0..5], so declare it to have six elements
        instead of just five.

1990-12-30  Richard Stallman  (rms at mole.ai.mit.edu)

        * eval.c (Fsignal): Don't ever return.
        Call error instead if user tries to use debugger to return.

        * eval.c (unbind_to): New second arg is value to return.  gcpro it.
        All callers changed to pass the arg; if a caller uses unbind_to
        just before returning, it passes as this arg the value it wants
        to return, then it returns whatever comes back.

1990-12-28  Jim Blandy  (jimb at geech.ai.mit.edu)

        * print.c (print): put obj in a non-register variable so
        we could gcpro it.  Also fixed some syntax errors.

        * editfns.c (Fformat): declare nstrings, and declare nstrings and
        strings in a local block.
        (Fformat): XFLOAT(args[n]) isn't a float; ->data is.

1990-12-27  Richard Stallman  (rms at mole.ai.mit.edu)

        * m-tower32.h: Add comments for how to optimize.
        * m-tower32v3.h: New file.

        Handle %e, %f and %g.

1990-12-25  Richard Stallman  (rms at mole.ai.mit.edu)

        * print.c: Don't use strout for the text of a Lisp string.
        (print_string): New function to use instead.
        (print): Use print_string when no escapes needed.
        When printing with escapes, protect the string and check addr often.

1990-12-24  Richard Stallman  (rms at mole.ai.mit.edu)

        * alloc.c (STRING_FULLSIZE): Use sizeof(struct Lisp_String)
        instead of sizeof(int).

1990-12-14  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * keyboard.c (Fread_key_sequence): Clear this_command_key_count
        here; who unfixed this?

1990-12-12  Richard Stallman  (rms at mole.ai.mit.edu)

        * abbrev.c (Fdefine_abbrevs): Don't crash when EXPANSION is nil.

1990-12-11  Richard Stallman  (rms at mole.ai.mit.edu)

1990-12-03  Jim Blandy  (jimb at geech.ai.mit.edu)

        * callproc.c (Fcall_process): change synch_process_pid to
        synch_process_alive, as a general flag that we are waiting for
        a synchronous process to die.  This obviates the need to block
        SIGCHLDs until we know the pid.
        * sysdep.c (wait_for_termination): wait for synch_process_alive to
        be false.

        * process.c (sigchld_handler): If pid not recognized, look for a
        process recorded with pid -1.
        (create_process): Set pid to -1 before the fork.
        Store correct pid right after the fork.
        Don't change sigchld handler on system V.

        * process.c (Fstart_process): Set BUFFER before other string vars
        so a gc in Fget_buffer_create won't clobber them.

1990-11-30  Richard Stallman  (rms at mole.ai.mit.edu)

        * keyboard.c (read_command_char): Save and restore getcjmp.

1990-11-29  Richard Stallman  (rms at mole.ai.mit.edu)

        * process.c (status_convert): Use WRETCODE for exited process.

1990-11-26  Richard Stallman  (rms at mole.ai.mit.edu)

1990-11-21  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * dispnew.c (init_display): Check if we're using a window system
        before trying to initialize the terminal.  If someone has
        indicated that they want to use a window system, we shouldn't
        bother initializing the terminal.  This is especially important
        when the terminal is so dumb that emacs gives up and doesn't bother
        using the window system.

1990-11-20  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * print.c (Fexternal_debugging_output): added new function which
        writes a character to stderr, for use when debugging emacs with
        gdb.

1990-11-14  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * dispnew.c (window_change_signal): used to assume that SIGWINCHes
        always applied to the currently selected screen.  Now it scans the
        list of screens for a screen controlled by termcap, and changes that
        screen's size.

1990-11-13  Richard Stallman  (rms at mole.ai.mit.edu)

        * fileio.c (err_str): New macro.
        (Finsert_file_contents, Fwrite_region): Use it in error messages.

1990-11-12  Richard Stallman  (rms at mole.ai.mit.edu)

        * insdel.c (del_range): Supply missing arg to gap_left.

1990-11-11  Jim Blandy  (jimb at churchy.ai.mit.edu)

        * regex.c: Disabled definition of NULL from lisp.h

        * xfns.c: added definition for Vbar_cursor.
        (syms_of_xfns): Added DEFVAR_LISP clause for Vbar_cursor.

        * xterm.c (XTread_socket): passed &event.xkey instead of &event to
        XLookupString, so things will typecheck nicely.

        * Globally rewrote all references to Vmouse_buffer to use the
        buffer viewed by Vmouse_window instead.

        * alloc.c (xmalloc, xrealloc): removed calls to
        {un,}hold_window_change.  The new SIGWINCH-handling code and
        do_pending_window_change make them unnecessary.

1990-11-11  Richard Stallman  (rms at mole.ai.mit.edu)

        * process.c (wait_reading_process_input): Make Available static;
        don't clear when a nonzero bit is found.

        * fns.c (Fnthcdr): Stop loop if reach end.

        * dispnew.c: Include fcntl.h if HAVE_TERMIO.

1990-11-10  Jim Blandy  (jimb at pogo.ai.mit.edu)

        * alloc.c (make_uninit_string): No longer declared static, and
