--- glyphs-x.c should really build with older png libs now

--- auto-show-mode is now off by default in edit-faces-mode
--- incorrect echoing when hitting 'f1 in tty mode fixed
--- png build problem fixed
--- terminal.el env requirement removed
--- gdbglobal doesn't turn on everywhere anymore
--- The bug where window-displayed-height didn't always return the

--- url 1.0.34
--- ediff 2.61
--- vm 5.96
--- viper 2.89
--- gnus 5.2.19
--- browse-url 0.36
--- corrected modeline overwriting being triggered by using ispell
--- fixed crash in tty-mode with edit-faces (again)
--- infinite loop when using surrogate minibuffer fixed
--- corrected handling of buffer arg to call-process
--- SCO 5 patches from J. Kean Johnston
--- patch from Bill Perry to eliminate using temporary files when
-   handling PNG files
--- Sun-provided CDE-friendly icon now default XEmacs icon.
--- canna support integrated (Thanks to Moroika Tomohiko).
--- apropos.el sync'ed with FSF Emacs 19.31 - Fixes the
-   `Nothing to follow here' problem.
--- set-process-filter no longer crashes if the process is dead.
--- x-compose.el now works again on Solaris.
--- New function x-keysym-on-keyboard-p helps determine keyboard
-   characteristics for key rebinding:
-
-  x-keysym-on-keyboard-p: (KEYSYM &optional DEVICE)
-    -- a built-in function.
-  Return true if KEYSYM names a key on the keyboard of DEVICE.
-  More precisely, return true if pressing a physical key
-  on the keyboard of DEVICE without any modifier keys generates KEYSYM.
-  Valid keysyms are listed in the files /usr/include/X11/keysymdef.h and in
-  /usr/lib/X11/XKeysymDB, or whatever the equivalents are on your system.
-
--- Sun key rebinding changed yet again to use function-key-map.
-   Type 4 keyboards have r35 mapped to `next'.
-   Type 5 keyboards already have `next', so map r35 to `kp_next'.
--- (Mule) Some menubar items will be translated by default in a
-   Japanese locale.
--- Sun key rebinding changed again to use function-key-map.
--- inheritance loops in face property specifications no longer cause
-   XEmacs to crash.
--- minibuffer-setup-hook no longer clobbered by read-file-name.
--- extra icons in Info mode removed.
--- XEmacs info top level sub-headers synched up with lower-level headers.
--- gnuclient prompts you with a dialog box when asking questions.
--- the yes/no dialog box now has sane options: yes, no, yes all, no all,
-   and cancel.
--- make-face-bold, make-face-italic, et al. do a better job than before --
-   they know about inheritors like [bold] and [italic], and will use
-   one if their normal X frobbing isn't successful.
--- better handling of bad menu filter functions.
--- buffers-menu improvements.
--- query-replace now disables case-folding if uppercase letters are
-   in the search string, like isearch does. (To turn both of these off,
-   set `search-caps-disable-folding' to non-nil.)
--- C-h ? ? works.
--- Chuck -- you need to re-byte-compile finder.el to fix C-h p under 20.0.
-   It wouldn't hurt to recompile everything.
--- weird bug with markers and standard-output fixed.
--- save-options now saves to a file `.xemacs-options' instead of directly
-   to .emacs.  .emacs is set to load .xemacs-options.  The file is
-   loaded with `load-options-file', which will allow eventually for
-   automatic updating of out-of-date options files.
--- Pretty-much everything in that spawn-of-hell file terminfo.c
-   is commented out now for most systems, since we didn't actually
-   need any of it!
-
-to 20.0 beta24
-
--- gnus 5.2.12
--- filladapt 2.08
--- fixed padding problem in modeline
--- fixed geometry problem with Athena scrollbar; it no longer has any
-   border and isn't going to at least for 19.14
--- bug where save-places didn't work correctly with a file given on
-   the command line is fixed
--- The global ospeed is completely unused now if TERMIOS is defined.
-   Before I actually remove the defines (which might fix those header
-   conflicts) I want some confirmation that doing this doesn't cause
-   problems in tty mode.  This change fixes a crash being seen when
-   running with the -nw flag on Irix 5.3 (binary built with gcc).
--- minibuffer echoing now works properly with surrogate minibuffers
--- A number of crashes which were reported when trying to use
-   surrogate minibuffers are fixed.
--- font-lock-add-colors now adds colors and only colors
--- --exec-prefix and the other path altering flags should work
-   NOTE:  I have not fully tested it because I would have to do
-   nothing other than run configure all day to do so.
--- It should now work to use XEmacs as a login shell; note that if you
-   start to stray from a default installation setup this may still be
-   broken.
--- possible fix for Vladimir's crash in Lstream_close().
-
-to 20.0 beta23
-
--- gnus 5.2.10
--- w3 2.3.65
--- url 1.0.32

-   handling JPEG's
--- patch from Bill Perry to support 'pointer extent property
--- corrected a bug where annotations in the left outside margin which
-   were equal to the width of the margin would not be displayed
--- Sun keybindings done like in 19.13 - true X keysym always works.
--- ispell works - (accept-process-output) bug fixed.
--- M-x manual-entry works on SysV with RosettaMan installed.
--- process output no longer inserts gratuitious C-d's UNLESS line to
-   be sent to process is longer than 256 characters.
-   (This still needs to be fixed so that C-d's are only inserted if
-   the tty is in canonical mode).
--- More type casting fixes to remove compiler warnings.
--- Random improvements to the Lisp Reference Manual.
--- XIM XCreateIC now always specifies a `Spot Location'.
--- If `sparcworks' is not on the PATH, but is in /opt/SUNWspro/bin,
-   add /opt/SUNWspro/bin to exec-path, and run eos::start.
-
-to 20.0 beta22

--- fixed crash in gif_instantiate when starting w3 in tty mode
--- fixed crash caused by grayscale jpegs
--- patch from Steven Baur to the psgml dtd catalog
--- patches to improve Athena scrollbars
--- fixes to delbackspace.el
--- merged s&m/ files, config*, unex* (mostly), getloadavg.c up to FSF 19.31.
-   This might fix Lynn's AIX problems.
--- better Java font-lock keywords (e.g. tries real hard to fontify
-   method names in their definitions).

--- fixed problem with display of right side toolbar
--- removed fa-extras.el
--- AIX configure patchs
--- updated sysdep.el from Bill Perry
--- delbackspace.el now uses the new key-translation-map, so it's less
-   kludgy.
--- vrml-mode.el gained some VRML 2.0 support.
--- fixed crash in x_output_string triggered by balloon help; this
-   almost certainly was causing a number of other reported crashes
--- fix for "obfuscated and incorrect way of saying 'Solaris'"
--- abort() in execute_internal_event() should be fixed
--- gnuattach now opens a TTY on *scratch* if given no args.
--- gnuattach now passes in the TERM type of the TTY it's run on.
--- TTY routines in XEmacs now use filedescs directly instead of FILE *'s;
-   should fix AIX gnuattach problem.
--- VM is smart about whether to install its toolbar on the selected frame
-   or current buffer.
--- new function `set-device-class' (you can say that your TTY device
-   is color even if it's not apparent from the TERM type)
--- selection/unselection of devices/consoles is "idempowered".
--- added option for sample.emacs to the Help menu.
-

--- fixed crash when starting w3 in TTY mode
--- memoize_extent_face_internal() crashes fixed.

-   when exiting.
-
-to 20.0 beta19
-
--- w3 2.3.52
--- url 1.0.21
--- func-menu 2.43
--- pcl-cvs autoloads corrected
--- --extra-verbose now implies --verbose as well
--- crash in x_get_gc when called from x_output_string should be fixed
--- The configure.in code to detect h_errno and sigsetjmp was broken,
-   unless your compiler supports nested functions (as gcc does).
-   AC_COMPILE_CHECK takes a FUNCTION BODY, not a FUNCITON, as one of
-   the arguments.  I have some trepidation on making these changes as
-   there are some comments in solaris header files about disabling
-   sigsetjmp, but at least the configure test now works - and XEmacs
-   still seems to, too.
--- Sun support in configure.in has been rewritten.  SunOS 4.1.1 through
-   4.1.4 has been tested.  The configure code for suns has been greatly
-   simplified.
--- Xmu detection should now work on SunOS4.
-
-to 20.0 beta18

--- w3 2.3.43
--- url 1.0.20
--- ediff 2.59 (again; this should have a higher rev)

-   problems

--- word-search-{forward,backward} crash fixed
--- easymenu.el patch from Per Abrahamsen
--- ClearCase VC support from Rod Whitby
--- lib-complete now dumped; improved find-library
--- make-x-device patch for TTY mode from Bill Perry
--- extent-faces-as-list lossage patch from Bill Perry
--- multiple definition cleanup
--- mailcrypt update for sgnus
--- new function isearch-toggle-case-fold
--- new function device-sound-enabled-p
--- background.el lossage fixed
--- find-dired lossage fixed
--- if XEmacs cannot deduce a bold-italic font from the default, try
-   copying the bold face and doing make-face-italic - if that fails,
-   try copying the italic face and doing make-face-bold.  With the
-   XResources in the bug report, I get the correct fonts now - please
-   try.
--- default-popup-menu now intelligently greys out its menu items
--- don't put up the load .emacs button in the menubar if the file
-   doesn't exist
--- actually let the 'Frame-local font menu' work!  The call to
-   (set-face-font 'default ...) was not specifying the frame as a
-   locale, so all changes to that face were global.
--- more bugs fixed, including some for core dumps.  If there are any
-   remaining core dumps in b18, please yell so that they get fixed.
--- `pointer' face works now.
--- `colorize-image-instance' changed incompatibly (previously it did
-   bad things).  I don't think this matters because no one seems to
-   use this function anyway.
--- browse-url 0.30 (includes Lynx support)
--- updated f90.el
--- cperl-mode (although not enabled by default)
--- skeleton.el
--- improved Linux native sound support

--- fixes to focus handling -- should fix "delay noticing focus change after VM
-   invoked"
--- uses ncurses if available -- better terminal support.
--- if you have color xterm and set your TERM to xterm-color,
-   XEmacs will use color on TTY's (at least under Linux).
-   Under linux, TERM=linux or TERM=ansi also has this effect.
-   (In general, any terminal type that defines color capabilities
-   in terminfo.)

-
--- w3 2.3.39
--- url 1.0.17
--- curmudgeon-mode: Just so all you curmudgeons will shut up.
-   `enable-curmudgeon-mode' sets all the old minibuffer, etc. behavior
-   that you're used to.  You can also give a particular category for
-   curmudgeonization.
--- func-menu 2.38.
--- enriched.el, face-menu.el from Michael Sperber.
--- If you're in a help buffer, you can exit using q and the previous
-   window config is restored.  Help buffers are now selected by default
-   to make this easier (but you can get the old behavior using
-   curmudgeon mode).
--- `eq' now works on face properties even if they're lists -- the
-   lists are "memoized".
--- numerous bugs fixed -- see the Web page.

-
-READ THIS FIRST:
-
--- emacs-version for 20.0 now reports 20.0, not 19.20.  This is gonna
-   break some packages that do incorrect version tests.  Both 19.14
-   and 20.0 now include the function `emacs-version>=' from emacs-vers.el,
-   which is a correct version test function.  If you want to use this
-   (highly recommended!), put code in your file like
-
-   (or (fboundp 'emacs-version>=)
-       [copy definition of emacs-version>= from version.el])
--- Byte code emitted by XEmacs 20.0 is NOT, repeat NOT, downward
-   compatible.  Byte code compiled in any Emacs 19 is upwardly
-   compatible to v20. (For the most part, that is ...) However,
-   you can force v19 compatibility under XEmacs 20 by setting
-   `byte-compile-emacs19-compatibility' to non-nil.
--- (This latter change is the result of a better solution to the
-   "char-int confoundance syndrome" problem, although it was
-   planned anyway.)

--- w3 2.3.36
--- url 1.0.16
--- viper 2.86
--- ediff 2.59
--- cc-mode 4.282
--- func-menu 2.37
--- mailcrypt 3.4 (2.x has been removed)
--- The appropriate function-key and arrow-key definitions should
-   now be set up automatically in TTY mode, for a number of different
-   terminal types.  Please review the terminals in lisp/term/ and
-   see if there's anything wrong.  Also, feel free to supply new
-   terminal definition files.
--- blink-cursor-mode.  This gets you the blinking cursor that lots
-   of people have been wanting for awhile.  There is a menubar
-   entry for this.
-   NOTE: There is currently a redisplay bug whereby the cursor
-   won't blink if it's at the end of the line.  Hopefully Chuck
-   will fix this soon.
--- wing-psgml-mode: A "grand unified mode" for HTML.  I started out
-   with PSGML, which is a way cool and powerful mode for editing SGML,
-   but extremely un-user-friendly in its current form.  I combined it
-   with some setup stuff from Alastair Burt and took some stuff
-   (the template stuff) from the hm--html-menus package.
--- improved file-dialog-box; some help from Rich Williams here.
--- improved completion-list-mode. (This is the mode for the lists
-   of completions.) Hit SPC in the minibuffer and you'll end up in
-   the completion list buffer, and can move around and select things
-   in a sensible fashion.  This should be a friendliness improvement
-   for TTY mode and such.
--- improved edit-faces.  It uses the new list-mode also and has
-   other new user-friendly features.
--- auto-show mode is now dumped and is enabled by default.  This
-   will automatically scroll the window horizontally as necessary
-   to keep point in view. (buff-menu is no longer dumped, so there's
-   a net decrease in the puresize.)
--- There is a menubar entry for Bookmarks.
--- `show-message-log' and the associated menubar entry no longer exist.
-   Instead, use `view-lossage' (C-h l).  There is now a menubar entry
-   for this under Help.
--- etags is merged with FSF 19.30 (adding Perl support, among other
-   things), and some Mly-induced breakage that resulted in pathologically
-   long relative filenames in the TAGS file has been fixed.
--- tcl.el 1.50.
--- annoying VM auto-raise of frame is gone.
--- I fixed a number of bugs with this-command-keys and C-g.
-   e.g. the C-x ? C-x C-h bug is finally gone.  If you see any more,
-   please pipe up and I will try to fix them. (A lot of the event code
-   is rotting, though, so not everything can be fixed ...) Also, if
-   you notice any weird behavior, *please* speak up!
-
-BUILD-LEVEL CHANGES:
-
--- When XEMACS_DEBUG is defined and XEmacs is dumping, the number of
-   bytes of purespace used by each loaded file is displayed.
--- Linux no longer defines BROKEN_SIGIO.
--- Linux binutils-2.6.0.10 breakage is no longer.
--- fixes for building under SunOS.
--- configuring without database support now works.
--- you can fix up the autoloads using `make autoloads' in the top
-   level directory.
-
-LISP-LEVEL CHANGES:
-
--- Hyperbole is still broken, sigh.
--- function-key-map and key-translation-map are now properly implemented.
--- keyboard-translate-table now lets you translate keysyms, e.g. to
-   fix the grievous damage Sun did to their X keyboards.  See the
-   function `keyboard-translate'.
--- The function `window-height' has been changed to return a different
-   value when a horizontal scrollbar is present.  The new definition
-   makes window-height ``mathematically tractable'': Its value always
-   reflects the window geometry, and will not change if you turn off
-   or on the modeline or horizontal scrollbar.  Also, now, when there
-   is only one window, frame-height always equals window-height.
--- The new function `window-displayed-height' returns the actual
-   number of text lines currently visible (making proper allowances
-   for blank space at the end of a buffer).  You should use this
-   instead of the standard kludge `(1- (window-height))'.
--- Hash tables can now do their comparisons with `equal' instead of
-   `eq'.  See `make-hashtable'.
--- The `face' property of extents and text properties can now be
-   a list.
--- derived.el has been fixed up and is now dumped.
--- cl.el is now dumped.  This includes the most basic of the
-   Common Lisp functionality; the rest is autoloaded. (And with
-   the lazy byte-code loading, it will come in only as needed.)
-   Accordingly, I removed the (usually less powerful) XEmacs versions
-   of `intersection', `union', etc., `delete-if', `delete-if-not',
-   `push', `pop', `c[ad][ad][ad]?[ad]?r', etc.  This should clear
-   up any remaining problems with ediff and such.  Note that the
-   increase in purespace from doing this is actually quite small --
-   about 15K.
--- At least one function (`display-completion-list') has been rewritten
-   to take Common Lisp key-style arguments.  This provides a sensible
-   alternative to having zillions of optional arguments in an
-   unrememberable order.  Other packages might consider doing the
-   same.
--- completion-list-mode is actually defined using `define-derived-mode',
-   as a sub-mode of list-mode.  edit-faces defines another sub-mode
-   of list-mode.
--- some patches from Darrell Kindred.
--- new specifier `text-cursor-visible-p' controls whether the cursor
-   is visible.
--- new face `text-cursor' controls the colors of the text cursor.
--- New file `gui.el' defining some functions useful for GUI stuff,
-   e.g. creating dialog frames and buttons.
--- The function `extent-at' now takes an argument AT-FLAG controlling
-   what it means for an extent to be "at" a position.  `get-char-property'
-   and `get-text-property' also take that argument.
--- `display-completion-list' has been changed to take key-type optional
-   arguments.  There are keys for controlling the activation callback,
-   the help string displayed, the window width, and other things.
--- New text-property functions `text-property-bounds' and
-   `next-text-property-bounds' facilitate looking for stretches of
-   specially-marked text.  This supersedes the common, error-prone
-   loops involving `next-single-property-change', `map-extents', etc.
-   (I thought long and hard about the end cases.)
--- `frame-visible-p' now actually queries the window system, so it
-   is always accurate without the need for weird kludges like
-   `accept-process-output'.
-
-MISC CHANGES:
-
--- Glyph and keymap lispref documentation should now be accurate
-   and up-to-date.
--- XEmacs uses sigsetjmp(foo, 0) when possible; this avoids lots
-   of sigprocmask() system calls that were happening.
-
-to 20.0 beta14
-
--- w3 2.3.32
--- XEmacs has a pseudo-file-dialog-box that gets invoked when you
-   choose a menu entry that prompts for a filename.  The code that
-   implements it is in `mouse-read-file-name-1' in minibuf.el.
-   It's a pretty cheesy-ass function but it gets the job done.
-   It clearly needs some work; beta testers out there are encouraged
-   to help here. (hint, hint)
--- there were some missing UNGCPRO's that might have led to weird
-   crashes.
--- Much improved xemacs-internals.  More is coming.
--- lots of improvements to the Lispref documentation, e.g. the general
-   section on objects is now actually more or less correct.
--- "cursor glyphs" and "cursor image instances" now use the term
-   "pointer" instead of "cursor".
--- new profiling code.  See `start-profiling', `stop-profiling',
-   `clear-profiling', `pretty-print-profiling-info', etc.
-   This uses a SIGPROF so it's only as accurate as your system timer
-   (100Hz under Linux on the x86; may be different on other systems).
--- I have tried hard to minimize the amount of allocation that happens
-   as a result of normal activities.  For example, `save-window-excursion'
-   and `save-excursion' no longer result in any allocation in most
-   circumstances.
--- New variable `debug-allocation'.  If you set this to non-zero, you
-   will get a record on stderr of every time that any allocation occurs,
-   and a short backtrace will accompany it (controlled by
-   `debug-allocation-backtrace-length').  Normally, set this to 1;
-   if you set this greater than 1, you'll also see the "noseeum" allocations
-   that happen internally and are later undone (thus causing no net
-   allocation).
--- byte-code objects print more sanely.  They also have an "annotation"
-   field indicating where they came from.
--- problem with lazy-lock sucking away idle time should be gone.
--- problem with mouse highlight not appearing may be gone.
--- problem with "interactive `e'" incorrect is fixed.
--- you can set and access all specifier and glyph variables using
-   frame properties.
-
-to 20.0 beta13
-
--- mode-motion+.el 3.15
--- hm--html-menus 4.16
--- ediff 2.54
--- viper 2.85
--- w3 2.3.30
--- url 1.0.13
--- nil is once again a valid color instantiator
--- 'make install' in a clean workspace should now work correctly.
--- Fixed a bug where using proportional fonts for the default face resulted
-   in an extra-wide frame.
--- Fixed wrong-type-argument error when using 'delete window above' from
-   modeline menu.
--- Fixed error when loading nroff-mode.
--- Fixed crash caused by this:
-	 (setq toolbar-file-icon '(blah)), then C-x b foo RET 
--- Error signaled if you try to create a frame with a `.' in the name.
--- frame size changes which occur while a tty-mode XEmacs is suspended are
-   now handled.
--- super-apropos is now apropos-documentation ; Help menu has been changed
--- tooltalk patch to allow setting of message disposition attribute (from
-   Hans Muller)
--- user-mail-address patch from Russell Ritchie
--- DEC OSF 4.0 patch from Manoj Srivastava
--- new specifiers default-toolbar-height, default-toolbar-width,
-   default-toolbar-visible-p, and {top,bottom,left,right}-toolbar-visible-p.
-   The new default specifiers work like default-toolbar: for whichever of
-   the four positions is the default-toolbar-position, the corresponding
-   specifiers foo-toolbar, foo-toolbar-{height,width}, foo-toolbar-visible-p
-   inherit from the appropriate defaults if no value is given.  I also redid
-   the toolbar size-handling code.  This appears to fix the weird problems
-   Kyle noticed with VM and the prev/next window config buttons, and might
-   have fixed that elusive VM phantom toolbar bug.
-
-to 20.0 beta12
-
--- gnus 5.0.15
--- cc-mode 4.281
--- now works in TTY mode, yay.
--- removed ill-conceived FSF Emacs post-command-idle-hook (added to
-   XEmacs in an earlier beta).  Replaced it with pre-idle-hook.
-   lazy-lock now uses this.
--- added frame-modified-tick for use by lazy-lock.
--- cursor overhaul is here.  Cursors are now specifiers.  Should make
-   them work properly on multiple devices.  Not working quite yet:
-   colored cursors.  I'll get to these.
--- various fixes, e.g. to font-lock.
--- cc-mode 4.280
--- dialog boxes work again. (e.g. Save-some-buffers from the File menu
-   works and uses the new-improved map-ynp stuff.)
--- I changed `set-specifier' so that it works more sensibly
-   (like `set-face-property' -- it takes a separate LOCALE and
-   TAG-SET argument, although the old way of specifying things
-   still works) and rewrote the incomprehensible gibberish that
-   masqueraded as its documentation so that it actually makes
-   sense now, even to someone who's not especially familiar with
-   specifiers.
-
-to 20.0 beta11
-
--- follow.el 1.5
--- oo-browser 2.9.11
--- hyperbole 4.01
--- w3 2.3.28
--- pretty much all reported bugs for the last betas should be fixed.
--- event crash from "M-x followed by mouse click" fixed.
--- fixed a nastily subtle bug in `kill-all-local-variables' that has
-   been around since mly's symbol rewrite some two years ago.  This
-   bug could potentially have resulted in all sorts of inconsistent
-   and difficult-to-track behavioral problems.
--- fixed another nastily subtle bug that had to do with extent
-   parents/children.  This feature should finally work correctly now,
-   because it's actually being used (in the modeline).
--- exported weak list interface (new functions `weak-list-p',
-   `make-weak-list', `weak-list-type', `weak-list-list',
-   `set-weak-list-list') so I could test it -- it's used in extents
-   to fix that nastily subtle bug just mentioned.
--- I removed the disgusting "feature" of being able to use `elt',
-   `concat', `length', etc. on compiled-function objects, and fixed
-   the small number of places that relied on this.  However, if you see
-   an error of the sort
-
-   As of 19.14, `foobar' no longer works with compiled-function objects
-
-   then I missed a place.
-
-   Note that there are accessors `compiled-function-*' for properly
-   accessing the contents of a compiled-function object.  These
-   accessors have been around since at least 19.8, so this is not
-   an overly bold change to make.
-
-   NB: Chuck says the cruddy `aref' stuff is going back into 19.14,
-   but will disappear for good in 19.15.
--- you can now dump faces into the dumped XEmacs.
--- modeline changes:
-   -- The (GLYPH . KEYMAP) and (FACE . FOO) modeline specs have gone
-      away.  In place of this, use (EXTENT . FOO).  The face, keymap,
-      and help-echo properties of the extent are noticed.  Nested
-      keymaps are handled correctly, but not nested faces as yet.
-      See `modeline-format' and `generated-modeline-string' for
-      details about how this all works.  It's way cool.
-   -- colored sections of the modeline generally indicate that you can
-      "do something" with button2 or button3.  button2 does something
-      immediately while button3 brings up a menu. (Clicking button2
-      on a non-colored section of the modeline does nothing, while
-      clicking button3 there brings up the standard modeline menu.)
-   -- clicking button2 on the "read-only" marker toggles read-only status.
-   -- clicking button2 on the right half of the buffer ID (the part that
-      says " foobar.c") cycles to the next buffer.
-   -- clicking button2 on the left half of the buffer ID (the part that
-      says "XEmacs:") cycles to the previous buffer.
-   -- clicking button3 anywhere on the buffer ID brings up a Buffers
-      menu.
-   -- clicking button2 on the ID strings of certain minor modes turns
-      them off (such modes are displayed in green instead of red).
-      ("Certain minor modes" means minor modes that correctly call
-      `add-minor-mode' to announce themselves instead of just
-      smashing minor-mode-alist directly.  I've fixed some modes to
-      do this.)
-   -- clicking button3 on any mode ID string brings up a menu that lets
-      you toggle certain minor modes. (#### Should also let you change
-      the major mode.  How do you get a list of all major modes that
-      exist, sans the uninteresting ones?)
-   -- clicking button2 on the "Narrow" string of a narrowed buffer
-      widens the buffer.
-   -- help-echo is given for all button2 actions.
--- save-options wraps its outputted forms in (if (featurep 'foo)) to
-   make sure that your .emacs will load OK in a differently-featured
-   XEmacs from what you saved the options in.
--- new function `set-face-parent' for properly making one face inherit
-   all attributes from another.
--- `set-extent-endpoints' can be used to move an extent from one
-   buffer to another.
--- semi-new function `event-glyph' returns the glyph underneath an
-   extent.
--- fixed bug in `recover-session' ... tsk tsk beta testers.
--- new function `mapc' -- like mapcar but doesn't accumulate results.
--- switched back to newer version of paragraphs.el; corrected
-   filladapt.el to mesh properly with it.
--- now autodetects -lgdbm as well as -ldbm, and uses the appropriate
-   one.  The --with-database option takes a comma-separated list
-   of one or more of "dbm", "gnudbm", and "berkdb", or "no" to
-   disable.
--- autodetects png, both with -lz and -lgz.  You can explicitly
-   call for png with -lgz using --with-png=gnuz.
--- autodetects libXmu absence.
--- configure option for NO_UNION_TYPE enabling/disabling provided.
-   It's called --use-union-type.  WARNING: GCC (esp. 2.6.0, 2.6.3,
-   2.7.0) will probably fuck up and generate incorrect code if
-   you use this option.
--- finally repaired the grievous damage that is `frame-parameters' --
-   use `frame-property', `frame-properties', `set-frame-property',
-   and `set-frame-properties' instead.  `frame-parameters' and
-   `modify-frame-parameters' are still supported but obsolete.
-
-   "Frame properties" are not only a different interface but actually
-   let you store arbitrary properties along with a frame, and
-   retrieve them later.
-
-   `frame-property' is much more efficient than `frame-parameters'
-   because it is non-consing.
--- new functions `alist-to-plist', `plist-to-alist',
-   `destructive-alist-to-plist', and `destructive-plist-to-alist'
-   to make it easier for you to convert between alists and plists,
-   such as you might do with frame properties/parameters.
--- A whole host of new functions for working with plists.
-   There is also a parallel set of these functions for "lax plists",
-   which are plists where comparison between keys is done with `equal'
-   instead of `eq'. (Frame property plists are this way because the
-   keys can be strings.)
--- The monstrous spawn-of-hell function `display-buffer' has been
-   moved into Lisp, so you can play around with it if you want
-   to.
--- New functions `push-window-configuration', `pop-window-configuration',
-   `unpop-window-configuration'.  The latter two implement a
-   Netscape-like forward/back movement through window configurations.
-   `display-buffer' automatically pushes a window config if anything
-   changes as a result of the call, so you can easily undo the results
-   of asking for help and such with just a mouse click.
-
-   PLEASE someone come up with better icons.  I just stole the Info
-   arrows.
--- The dreaded FSF dynamic byte-compile format is here.  It is *NOT*
-   repeat *NOT* enabled by default for 19.14, so it's not gonna
-   break anything.  It *IS* yes that's right *IS* the default for
-   20.0. (Both kinds of dynamic byte-compiling are the default
-   for 20.0.) Therefore, files you compile using 20.0 won't be
-   readable under versions before 19.14 unless you set
-   `byte-compile-dynamic' and `byte-compile-dynamic-docstrings'
-   to nil before compiling.  Note that 19.14 will recognize
-   and correctly read dynamic byte-compiled files (whether compiled
-   by 20.0, 19.14, or FSF 19.29 or above), even though it won't
-   generate them by default. (You have to set one or both of
-   those variables just mentioned to non-nil if you want this.)
-
-to 20.0 beta10
-
--- cc-mode 4.273 (includes java-mode from Eduardo)
--- edebug 3.5
--- first line display problem on ttys fixed
--- problem with cursor position after exiting tty mode fixed
--- cheap fix for the filladapt problem; completely backed out the sync
-   of paragraphs.el with 19.30.  One of the changes in
-   forward-paragraph is causing the problem.
--- Faces can now be embedded in the modeline.  Add a cons where the
-   car is a face object and the cdr will be evaluated as usual but the
-   results of it will be displayed in the given face.
--- Glyphs can now be embedded in the modeline, along with a keymap to
-   make them active.  For a glyph which just displays you can insert
-   just the glyph.  To include a keymap, add a cons with the car as
-   the glyph object and the cdr as the keymap object.
--- cut redisplay's memory consumption by 1/3
--- fixed a memory leak in the scrollbar code
--- font-lock basically synched with 19.30.
-   LISTEN UP: I changed the way font-lock faces are initialized.  It
-   now takes advantage of the specifier stuff added in 19.12, and sets
-   up color defaults for color machines and non-color defaults for
-   non-color machines.  The defaults are added with `append', which
-   means that if you add your own values, they'll override the defaults
-   regardless of when you do it.
-
-   SO: Please try temporarily disabling all your font-lock customizations
-   and comment on what you think of the new defaults.
--- major DUH factor.  The cause of the 10%-CPU-usage-while-XEmacs-is-idle
-   was that the "quarter-second timer" was actually set to fire
-   1000 times per second.  I think I must have changed this at one
-   point to debug something, and never set it back.  Oops ...
-   If you set `debug-emacs-events' to non-zero on a Linux or IRIX
-   machine, you'll now see blank eval events going by at a reasonable
-   rate (4 times per second) instead of spewing out like water from
-   a firehose.
--- yet more synching with FSF 19.30.
--- Lots of modes have gained menus.
--- recover-session (recovers all auto-saved files) should work.
-   Not really tested.
--- latest apropos.el from 19.30.  Implements some of what Hyper-Apropos does.
-   Maybe we should junk apropos.el or integrate the two.
--- `display-buffer' synched with FSF 19.30.  This gives you the following
-   wondrous cruft:
-   -- unsplittable frames
-   -- pop-up-frames, pop-up-frame-function
-   -- special-display-buffer-names, special-display-regexps,
-      special-display-function
-   -- same-window-buffer-names, same-window-regexps
--- finally!  C-h k followed by a toolbar button press correctly reports
-   the binding of the toolbar button.
--- fixed problems with toolbar buttons remaining activated or C-g being
-   pressed during minibuffer prompting of (e.g.) toolbar Replace or Open 
--- fixed "Error setting GC pointer" problems.
--- text-property problems reported by Alastair Burt fixed.
--- ediff minibuffer weirdness fixed.  Surrogate minibuffers are working.
--- ~ has electric behavior like / in minibuffer.  Both of these can be
-   inhibited by setting `minibuffer-electric-file-name-behavior' to nil.
--- minibuffer completion lists are put into a special mode.  left, right
-   move to the next/previous completion.  enter selects the completion.
-   button2 selects, as always, but will always be accurate as to the
-   completion -- no regexp-based guesswork, as before.
--- the kludgy completion-tracking behavior that looks for completions
-   under the mouse has been disabled.  If you want it back, set
-   `minibuffer-smart-completion-tracking-behavior'.  This does *not*
-   affect the normal ability to click on a completion in the
-   *Completions* buffer.  Turning this off should also fix the obnoxious
-   "mouse motion causes ange-ftp action" bug.
--- ported latest map-ynp.el.  Used by `save-some-buffers'.
--- Bill Perry's database and strikethru patches.
-
-to 20.0 beta9
-
--- w3 2.3.26
--- crash caused by corrupting toolbar icon specs is fixed
--- no one complained, so I removed `local-pre-command-hook' and
-   `local-post-command-hook'.
--- follow-mode 1.5 beta (01-08-96); this lets you turn two side-by-side
-   windows into one twice-as-long "virtual buffer".
--- more synching with FSF 19.30.
--- ange-ftp should work.
--- new configure option --with-term, for support for TERM (Linux serial-port
-   multiplexer), for those who care.  The support was already present
-   in XEmacs, just no configure option.
--- jpeg code now just includes "jpeglib.h" instead of "jpeg/jpeglib.h",
-   and configure autodetects likewise.
--- new variable debug-emacs-events.  Set to non-zero to have all events
-   seen by XEmacs output on stderr. (From this, I know what's going on --
-   it's the 1/4 second timers for when SIGIO and/or SIGCHLD are broken.
-   It can be fixed, but not until the next beta ...)
--- overriding-terminal-local-map and other oddities from FSF.
--- added some of the necessary C support for lazy-lock v2.
--- ange-ftp works around a Linux FTP problem where it outputs escape
-   sequences to highlight the ftp prompt, which messes things up.
--- I changed a couple ange-ftp defaults:
-   -- ange-ftp-generate-anonymous-password is t.  I see no reason
-      why you should have to type in a password here.
-   -- ange-ftp-default-user is "anonymous".  This one is more
-      debatable, but I think it's a lot more logical (more like
-      ncftp, too) and follows the Principle of Least Surprise.
-      Differing opinions (except from Kyle Jones :) are welcome.
--- Info menu now properly disappears when you exit Info.
--- new functions frame-leftmost-window, frame-rightmost-window.
--- next-frame and previous-frame have been expanded and unkludgified
-   to allow you more control over which frames are considered.
--- Bill Perry's GIF and PNG patches are included.
--- Various patches for the DEC Alpha and other beta-list patches
-   are in place.
--- function to access the raw window tree have been added:
-   window-first-hchild, window-first-vchild, window-next-child,
-   window-previous-child, window-parent.  These let you implement
-   frame-leftmost-window and lots of similar functions.
--- XEmacs should be more robust about dying properly when crashes
-   occur.
--- you can compile with Epoch support. (Actually, you could in the
-   previous beta, too.) The main thing this gets you is direct
-   access to some X events and objects (e.g. properties and
-   property-notify events).
--- you can set initial-frame-alist in your .emacs, and XEmacs will
-   notice this and change the initial frame accordingly.
--- major revamping of the multi-device support:
-     -- there is a new type of object called a "console".  A console
-        groups together devices that have the same keyboard/mouse.
-        A "device" now corresponds to an X "Screen", while a "console"
-        corresponds to an X "display".  You don't need to explicitly
-	create a console; it's created as necessary when you create
-	a device.
-     -- device-local variables have become console-local variables.
-     -- "device types" are now "console types", although functions
-	that speak of "device types" and "frame types" are defined
-	as aliases.
-     -- devices are no longer permanent objects, but remain around
-	only so long as there are frames on the device.  Consoles
-	behave similarly. (#### not implemented yet; wait for
-	next beta)
-     -- Devices and consoles have a generalized concept of a
-	"connection", which describes what they are connected to
-	(e.g. a DISPLAY for an X console, a tty name for a TTY
-	console).  Calling `make-device' on an existing connection
-	returns an existing device and/or console rather than
-	creating a new one.  The code is also quite smart about
-	determining whether a connection refers to an existing
-	device or console; e.g. if your machine name is "nene.666.com"
-        alias "wing.vip.best.com" address 204.156.158.101, then
-	all of the following display specs are treated as equivalent:

-	localhost:0
-	nene:0
-	nene.666.com:0.0
-	wing.vip.best.com:0
-	204.156.158.101:0

--- url 1.0.12
--- viper 2.85
--- func-menu 2.35
--- SCO patches from Robert Lipe
--- XEmacs has a man page, finally.
--- lots of updates to the lispref docs.
--- s/, m/, and configure files synched with FSF 19.30.
--- extents-over-strings complete.  Extent replicas are no more.
-   You can get the same functionality by setting the `replicating'
-   property on an extent.
--- describe-mode puts major modes first (from Stig)
--- device-local variables are here.  A few variables are currently device-
-   local; eventually the whole command builder will be this way.
-   New function `symbol-value-in-device'.  Functions
-   `device-function-key-map' and `set-device-function-key-map' have
-   been removed.  `function-key-map' is instead a device-local variable,
-   with a default `default-function-key-map'.
--- XEmacs now preloads all code at dump time (except for some terminal-
-   or X-server-specific files, for which it's not fatal if they can't
-   be found).  Thus, you can delete the lisp directory if you really
-   really want to.
--- `open-dribble-file' works.
--- Info has a pulldown menu.
--- function `extent-descendants'.
--- you should be able to compile without scrollbars, menubars, and/or
-   dialog boxes.  This has been somewhat tested but may not work with
-   all possible configurations.  More testing would be appreciated.
--- there are better feature-tests available: to check for the presence
-   of menubars, scrollbars, dialogs, and/or toolbars, use `featurep'
-   with `menubar', `scrollbar', `dialog', or `toolbar'.  There are also
-   features `lucid-menubars', `athena-scrollbars', `motif-dialogs', etc.
-   etc. for whatever configuration you compiled in.
--- SPARCworks CYA message is only displayed if (featurep 'sparcworks).
--- lots of other stuff merged with FSF 19.30.  Change list:
-   -- Key changes:
-      -- C-x ESC -> C-x ESC ESC
-      -- ESC ESC -> ESC :
-      -- ESC ESC ESC is "abort anything" (keyboard-escape-quit).
-   -- indirect buffers.  These are buffers that share text with another
-      buffer but have their own major mode, extents, buffer-local variables,
-      etc.  Create with `make-indirect-buffer'.  See also
-      `buffer-base-buffer', `buffer-indirect-children'. (Not yet
-      finished implementing.)
-   -- new function `set-buffer-major-mode'.
-   -- `buffer-invisibility-spec' controls whether the `invisible' property
-       is applicable.
-   -- `inhibit-read-only' can be a list of property values; similar to
-       `buffer-invisibility-spec'.
-   -- new "file format" concept.  See `buffer-file-format',
-      `format-alist', `format-decode', `format-encode',
-      `insert-file-contents-literally', etc.
-   -- `call-process' can have a separate stderr specified.
-   -- Junky variables `self-insert-face' and `self-insert-face-command'.
-   -- `write-region' can take a sixth argument LOCKNAME (a lock file).
-   -- new function `find-alternate-file-other-window'.
-   -- improved margin functions -- `current-left-margin', etc.
-   -- newlines can be "hard" or "soft" -- I guess this affects filling,
-      paragraphs, etc.  See `use-hard-newlines'.
-   -- lots and lots of filling / justification / paragraph changes.
-   -- `shell-command' and related can take optional output buffer
-      specification.
-   -- `what-line' prints more information.
-   -- new functions `file-writable-p', `file-regular-p'.
-   -- new function `active-minibuffer-window'.
-   -- new function `cancel-kbd-macro-events'.
-   -- new functions `run-hook-with-args-until-success',

--- fixed problem with echo area redisplaying during macro execution
--- first version of "gnuattach", for viewing a file in the current
-   TTY frame.  Works like gnuclient.  I did a "good enough" implementation
-   because I don't understand fully how gnuserv works.  Someone else
-   might want to take a look at it.
--- fixed problems with bad cc-mode indentation
--- fixed ^G problems, likely fix for "XEmacs consumes too much CPU"
--- undo in the minibuffer.
--- problems with tight loop in sys_readdir() should be fixed.
--- char-tables are now readable; Bill Perry's eval-when-compile problem
-   should be fixed.
--- the unified range table code is now defensive about getting itself
-   misaligned, so it should work no matter what tricks realloc() plays.
-   This should fix the assertion failure, line 621 of rangetab.c.
--- next-window, previous-window, next-frame, previous-frame, other-window,
-   get-lru-window, etc. extended to take a device argument that allows
-   you to restrict which devices it includes (normally all devices).
-   Some functions that incorrectly ignored frames on different devices
-   (e.g. C-x 0) are fixed.
--- start-open, end-open, start-closed, end-closed now work correctly

--- we check for interrupted system calls in opendir(), readdir(),

-   errors people have been seeing with completion.
--- GIF support!  Since there appears to be no standard GIF library,
-   and since the code I found (giflib-2.2 from the Linux archives)
-   is quite small, I just put it in the XEmacs src directory.
-   NOTE: If you encounter problems with certain GIFs (e.g. interlaced),
-   let me know and I'll enable some currently dormant code.
-   NOTE: For the moment, GIF support is enabled everywhere because it
-   requires no special libraries or machine-dependent features.  You
-   can disable it using --with-gif=no.
--- JPEG support!  Compile with --with-jpeg (or just let it be
-   autodetected).  You need to obtain the standard JPEG library (libjpeg)
-   from the Independent JPEG Group.  One source is ftp.uu.net:/graphics.
-   Compiled Linux libraries (not the most recent version, but they work
-   fine) are available at sunsite.unc.edu:/libs/graphics.  You have to
-   specify the location of the libraries and include files using
-   --site-libraries and --site-includes.  Note that the include files
-   are presumed to be in a subdirectory "jpeg" of the --site-includes
-   directory.
--- Lstreams free their buffers when they are closed rather than
-   when they are GC'd.  This should avoid the memory bloatage noticed
-   when you repeatedly insert a lot of files, and should render
-   unnecessary the patch that Darrell Kindred submitted.
--- patch for possibly deadly Mule problem
--- XEmacs behaves reasonably in the presence of a bogus app-defaults
-   file
--- configure debugging: if you specify --extra-verbose, then any
-   error messages from compilation and preprocessor feature tests
-   will be output.  This is especially useful if your feature tests
-   are failing for no obvious reason.  #### Suggestions for a better
-   name than --extra-verbose are welcome.
--- warning messages will get generated if there is a problem displaying
-   an image, rather than just nothing happening at all.
--- You can disable toolbar support by specifying --with-toolbars=no.
-   This should reduce the code size a bit.
--- You can disable TTY support by specifying --with-tty=no.
-   This should reduce the code size a bit.
--- The oddly named "dont-have-xmu=yes" option is now "with-xmu=no".
--- loaddefs and keydefs are now compiled like other Lisp files.
--- You should get more accurate errors for many types of mistakes
-   with set-face-* functions.

--- TTY support should now be working properly under Mule.
-   If you are running under kterm, you should see the Japanese

--- TTY colors!  New functions `register-tty-color', `unregister-tty-color',
-   `find-tty-color', and `tty-color-list' for specifying the valid TTY
-   colors.  Of course, you need a terminal that is capable
-   of handling ANSI color sequences, e.g. Color XTerm or the Linux console.
-   The standard ANSI colors (black, red, green, yellow, blue, cyan,
-   magenta, and white) are registered by default so you can just go

-
--- new function `current-process-time' for retrieving the user, system,
-   and real times of the currently running XEmacs process. (for 19.14
-   probably.)
--- Here's a cool new demo that works under Mule: Load the file
-   `mule-doc/demo'.  This has "hello" written in a zillion different
-   languages / charsets.  Astute observers will notice two problems:
-   (1) Half of the Thai characters don't show up.  That's because
-   composite characters still aren't displayed properly.
-   (2) The Arabic and Hebrew characters go backwards from the way
-   they should. (Guess why?)
--- error-handling behavior in Mule decoding (e.g. unknown charset)
-   should be much better.  The goal here is that there should never be
-   any information lossage when a file is read in, decoded, encoded
-   again, and written out.  If escape sequences get transformed into
-   some other equivalent escape sequence, that is OK; but if they
-   get eaten, that is not OK.
--- translation tables are handled consistently (note, I didn't say
-   "correctly") under Mule.  Doing them correctly is very difficult
-   so I'm punting for now.  Basically, under Mule, `upcase' and
-   `downcase' (and related) work correctly with translation tables
-   but the string/buffer-searching routines will ignore translations
-   that map to or from a character not in the seven-bit ASCII
-   range -- thus `case-fold-search' will not correctly conflate
-   a-umlaut and A-umlaut.  This sucks, but it's better than the
-   alternative (weird results and possible crashes).
--- regex searches/matches should work properly with extended
-   chars under Mule.
--- fixed bad definition of xemacs-color-device in ps-print.el.
-   (for 19.14.)
--- fixed problems with command-line options -T, -wn, etc. not

--- Options sub-menu provided under Mule for setting the current

--- fixed some problems with nested GCPRO's, that could have lead to
-   weird crashes. (for 19.14.)
--- Things should *finally* work OK on the Alpha machines.
-   (Hopefully? Please?) (for 19.14.)
--- Tooltalk warning is now a real warning (class `tooltalk'), so
-   you can suppress it.
--- selections should work again. (for 19.14.)
--- syntax tables work under Mule. 
-
-   NOTE: Syntax tables are *NOT* vectors any more but are their own
-   abstract `char-table' type.  As such, some (broken) code is going
-   to break. (Typical error: "wrong type argument: sequencep,
-   #<syntax-char-table ...>".) I've already had to patch cc-mode,
-   font-lock, mail-abbrevs, and symbol-syntax, and edebug, mim-syntax,
-   and paren still need to be changed.  This is an unavoidable result
-   of RMS non-abstracted brokenness.  Yuck Yuck Yuck Yuck!
--- syntax table lookup should be faster (at least under non-Mule).
-   This could be a big win for scan-lists etc., and thus for cc-mode.
--- fixed version of set-text-properties. (for 19.14.)
--- fixes to display-warning-buffer to avoid problems when the
-   warning buffer is deleted. (for 19.14.)
--- If a font can't be instantiated, you should now only get one
-   warning instead of a trillion of them.
--- new Common-Lisp function `subseq', a generalization of `substring'.
-
-to 20.0 beta2
-
--- new functions `function-min-args' and `function-max-args' for
-   determining the number of allowed arguments in a function
-   (of any sort accepted by funcall). (possibly for 19.14.)
--- no more crashes under Mule if it can't find an acceptable font;
-   you just get a warning instead and a '~' character.
--- new variable `disable-auto-save-when-buffer-shrinks', providing
-   you with a way to turn off this widely-hated behavior. (for 19.14.)
--- new Common Lisp function `reduce'.
--- I added some defines that should eliminate zillions of
-   "warning, incompatible pointer type" warnings for the memset(),
-   memcpy(), memcmp() functions in SunOS 4.x. (for 19.14.)
--- composite characters are partially working under Mule.  They are
-   correctly handled internally, but are not yet displayed properly:
-   you just get the familiar '~'.
--- processes should now correctly do flushing of long PTY lines,
-   which they never did since the Lstream process rewrite sometime
-   during the 19.12 beta cycle.
--- processes should be working better under Mule (at least there
-   will be no loss of data, which was a possibility before).  More
-   work still to come in the area of handling encoding/decoding.
--- fixes to font-lock that should make it go *much* faster (esp. in
-   lazy-lock) when moving backwards or jumping to an arbitrary point
-   in the buffer.  Files like emacsfns.h are still problematic but
-   should be better than before. (for 19.14.)

--- w3 2.2.17
--- mailcrypt 3.4 is now the default
--- new version of icomplete.el from David Hughes
--- characters are now their own separate Lisp object type; this is
-   The Way It Should Have Always Been.  This change is necessary for
-   byte-code portability under Mule and follows the Common Lisp model
-   of not needlessly confounding separate types, as is (unfortunately)
-   the fashion under E-Lisp.  Characters print as characters using the
-   evil yucky GNU Emacs character syntax (e.g. ?a) rather than as
-   integers; this is the essence of the byte-code portability.  In
-   deference to existing E-Lisp code, the following concessions are made:
-
-   -- characters are represented directly; `eq' works on them.
-      (Yuck! This may be a problem if I ever want to add additional
-      information to characters.)
-   -- the comparison functions (<, =, etc) and arithmetic functions
-      (+, -, etc) accept characters and silently convert them to
-      integers. (This is semi-hateful but necessary for compatibility.)
-   -- functions that properly accept characters (e.g. char-to-string)
-      also accept integers and silently convert them to characters.
-
-   I have provided new character primitives `char<', `char=', etc.
-   that are the proper way of comparing characters.
--- The function `eq' has been infected with a heretofore-unknown virus
-   known as the "char-int confoundance disease".  The CDC has been
-   warned, but in this case the cure (require that all existing .elc
-   files in the whole world be re-byte-compiled) is a lot worse than
-   the disease.  Their recommendation is to use the new function
-   `really-eq' if you really need to distinguish between chars and ints.
-   Be warned, however, that this will run slower in byte-compiled code
-   because there is no opcode for `really-eq'.
--- Similar infections have happened to `equal' (with a corresponding
-   `really-equal') and to the functions `memq', `delq', `assq',
-   `rassq', `remassq', `remrassq' and corresponding `equal'
-   equivalents.  The functions `puthash' and `put-range-table' have
-   not been affected, however, because I don't think there will be much
-   of a compatibility problem here.
--- BETA TESTERS LISTEN UP: The above changes have the potential of
-   causing weird lossage in existing packages.  Therefore, PLEASE
-   PLEASE do the following for as many different packages as you can:
-     (1) try it out to make sure there's no obviously strange behavior
-         (a good example would be the error
-          "wrong type argument: integerp, ?B") or not-so-obviously
-         strange behavior, like prefix arguments not working
-	 (yes, this did happen).
-     (2) re-byte-compile all the files in the package
-     (3) repeat step #1.  Look especially hard this time because
-         the errors are more likely to occur this time.
--- typecheck error-checking has been added for integers and for chars.
-   You may hit some aborts.
--- XEmacs/Mule now performs automatic detection, encoding, and decoding
-   of files upon input and output. (Although the detection system definitely
-   has room for improvement.)
--- XEmacs/Mule is still untested w.r.t. subprocesses and TTY support and
-   thus is likely to fail with both.
--- XEmacs/Mule now byte-compiles files properly. (Well, it appears to ...
-   extensive testing has not yet been done.)
-   WARNING WARNING WARNING:
-   (a) You cannot compile files with extended characters in them
-       (e.g. lisp/mule/japanese-hooks.el) using a version of XEmacs
-       not compiled with Mule.
-   (b) If you compile such a file using XEmacs/Mule and attempt to
-       load it into a version of XEmacs not compiled with Mule,
-       you will get extremely random and undesirable results even
-       if you don't get a read error.  The reason for this is that
-       a special encoding is used to allow arbitrary binary characters
-       to co-exist with the control characters used to change
-       the encoding state.  Normal E-Lisp files compiled under
-       XEmacs/Mule should work under a non-Mule XEmacs because the
-       special encoding will not be used in this case.
-   At some point I would like to remove these gotchas but this will
-   require adding some smarts to the non-Mule XEmacs to be able to
-   at least partially handle the special encodings used.
--- Here is a cool test of XEmacs/Mule: type 'C-h T' (capital T) and
-   you can get an Emacs tutorial in the language of your choice
-   (currently limited to Japanese, Korean, and Thai).  Astute
-   testers will notice that the Thai one doesn't work yet; that
-   requires support for composite characters, which doesn't currently
-   exist.
--- a change has been made to the handling of markers that should
-   eliminate those 15-second GC pauses that some of you may have
-   been seeing while processing the output of M-x grep, etc.
-
-to 19.14 beta1
-
--- w3 2.2.16
--- mailcrypt 3.4beta
--- preliminary Mule support is provided.  This will get better over the
-   next month or so.  All of the basics except for input method support
-   are there, although it's still somewhat slow and some of the parts
-   may not fit together perfectly.
-
-   Here's a demonstration you can do when Mule support is enabled:
-
-   -- load the file etc/mule/TUTORIAL.jp
-   -- evaluate (decode-coding-region 1 (point-max) 'ctext)
-
-   In order for this to work, you have to have the proper Japanese
-   fonts installed (see below), or XEmacs will abort. (This will be fixed.)
-
-   Soon, the decoding will happen automatically upon loading.
-
-   Note also: IT MIGHT NOT CURRENTLY WORK TO BYTE-COMPILE FILES UNDER
-   XEmacs/Mule.   You may get bogus results.  Therefore, for the time
-   being do *not* do `make all-elc' using the built XEmacs/Mule.
-   This should be fixed by beta2, along with the rest of the file-
-   handling stuff.
-
-   Note finally: You may get read errors trying to byte-compile the
-   Mule files under the non-Mule Xemacs.  I have not yet come up with
-   a general solution to this problem. (I'm not convinced such a
-   solution even exists; byte-compiling could cause arbitrary code
-   to be executed, which will surely fail if the code uses Mule-
-   specific features.)
--- We now may have the world's largest collection of FTP-able
-   international X11 fonts.  Look in cs.uiuc.edu:/pub/xemacs/beta/fonts.
-   See the README file for directions on installing the fonts.  There
-   is also the potential for generating loads and loads more of these
-   fonts, by converting MetaFont fonts.
--- It is now possible to build simultaneously in the source directories
-   and in a separate build location, provided you have GNU make and
-   supply the `--with-gnu-make' option to configure.
--- Support for bit vectors is now provided.  Bit vectors are like regular
-   vectors except that the only allowed values for elements are 0 and 1,
-   and they are stored internally using bit fields instead of arrays
-   of 32-bit values, making them much less heavyweight.  New primitives
-   for working with bit vectors are `bit-vector', `make-bit-vector',
-   `bit-vector-p', and `bvconcat' (equivalents of `vector', `make-vector',
-   `vectorp' and `vconcat').  All other vector primitives should work
-   fine with bit vectors.
--- new specifier functions `specifier-matching-instance',
-   `specifier-matching-instance-from-inst-list', and
-   `valid-specifier-matchspec-p', for working with fonts in XEmacs/Mule.
-   These same functions could be used to provide much more flexible
-   handling of display tables and the like, and this work may get done
-   if there is demand for it.
--- The handling of PURESIZE has been fixed up.  There is no longer
-   special stuff needed in m/alpha.h.  Alpha users may need to tweak
-   with puresize.h.
--- You can now build statically on Linux.  Doing this will allow you
-   to get proper backtraces. (Shared libraries are typically built
-   -fomit-frame-pointer, which screws everything up.)
--- I have removed almost all of the MAC_* stuff and replaced it with
-   inline functions.  configure attempts to detect whether your compiler
-   supports `inline'.  However, if your compiler does support it
-   but is not GCC, you should look at how I've done things and see
-   if it meshes with your compiler.  Basically, GCC has a nice feature
-   where you can declare a function `extern inline' and stick it in
-   a header file.  This will cause the inline declaration to be
-   used if the function can be inlined, and an external reference to
-   be generated otherwise.  Then, you define the function just
-   `inline' in one single file (inline.c).  This is superior to the
-   method of declaring all inline functions as `static inline', which
-   could leave a separate copy of each function in lots of source
-   files.  However, I'm not sure if non-GCC compilers support this.
-   Please read your compiler's documentation and fix up the definition
-   of INLINE in config.h.in accordingly.
-
-   Also, there may be functions that would really benefit from inlining,
-   which you can sometimes specify as an option to your compiler.
-   We will have Quantify information on this.
--- XEmacs now uses the v19 regex routines instead of the v18 regex
-   routines.  Speed should not be significantly different due to the
-   non-Posix-backtracking default.  If you want the full Posix
-   backtracking, use the functions `posix-looking-at', `posix-string-match',
-   etc. (Be warned that this may be significantly slower.) Note also
-   that the fishy problems may be forever banished.
-
-   NOTE: The v19 regex routines do reallocs using rel-alloc if it is
-   available; God only knows why.  If you notice some weird hiccups in
-   the regex routines, this is a likely culprit.  Someone might want to
-   try putting '#undef REL_ALLOC' at the top of regex.c or something.
-   RMS also claims that much of the stuff that's going on here (recording
-   backtracking points) is only necessary for full Posix backtracking,
-   and thus we should be able to disable it in the normal (non-Posix)
-   case.
--- XEmacs now caches compiled regexps.  This may speed up regex searching.
--- `replace-match' now takes a fourth argument STRING that allows for
-   replacement in a string instead of a buffer.
--- new functions `upcase-initials' and `upcase-initials-region' from
-   FSF Emacs 19.29.
--- match data is automatically saved and restored while a process filter
-   or sentinel is running.
--- new type "char-table".  A char table is for indexing characters and
-   is intended to be an extension/generalization of syntax tables,
-   display tables, case tables, category tables (a new kind of beast
-   allowing classifications of characters into categories for regexp
-   lookup, useful esp. for Mule), etc.  You can set values for
-   an entire charset and for individual rows of a charset.  Adding
-   and looking up values occurs in constant time.
--- new type "range-table".  A range table efficiently indexes ranges of
-   integers to values.
--- new modeline spec '%C'; displays a mnemonic string for the
-   file-coding-system, under Mule.
--- new function `device-on-window-system-p'; clean way of determining
-   whether mouse, glyph, etc. support is likely to be available on this
-   device.
-   #### We really need individual feature-test functions.
--- new dialog-box functions `get-dialog-box-response' (like the misnamed
-   `x-popup-dialog' FSFmacs function), `message-box' (like the FSFmacs
-   function), and `message-or-box' (like the FSFmacs function).
