 This file describes various problems that have been encountered
 in compiling, installing and running XEmacs.  It has been updated for
-XEmacs 21.1.
+XEmacs 21.2.
 This file is rather large, but we have tried to sort the entries by
 their respective relevance for XEmacs, but may have not succeeded
 completely in that task.  The file is divided into four parts:
 * Problems with building XEmacs
 ===============================
-** General
+** Don't use -O2 with gcc 2.7.2 under Intel/XXX without also using
-*** Don't use -O2 with gcc 2.8.1 and egcs 1.0 under SPARC architectures
-without also using `-fno-schedule-insns'.
-gcc will generate incorrect code otherwise, typically resulting in
-crashes in the function skip-syntax-backward.
-*** egcs-1.1
-There have been reports of egcs-1.1 not compiling XEmacs correctly on
-Alpha Linux.  There have also been reports that egcs-1.0.3a is O.K.
-*** Don't use -O2 with gcc 2.7.2 under Intel/XXX without also using
 `-fno-strength-reduce'.
 gcc will generate incorrect code otherwise.  This bug is present in at
 least 2.6.x and 2.7.[0-2].  This bug has been fixed in GCC 2.7.2.1 and
 later.  This bug is O/S independent, but is limited to x86 architectures.
 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
-*** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
+** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
 using `-fno-caller-saves'.
 gcc will generate incorrect code otherwise.  This bug is still
 present in gcc 2.7.2.3.  There have been no reports to indicate the
 bug is present in egcs 1.0 (or pgcc 1.0) or later.  This bug is O/S
 independent, but limited to x86 architectures.
 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
-*** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
+** Excessive optimization with pgcc can break XEmacs
-When using gcc, you get the error message "undefined symbol __main".
-This means that you need to link with the gcc library.  It may be called
-"gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
-config.h to point to it.
-It may also work to use the GCC version of `ld' instead of the standard one.
-*** Excessive optimization with pgcc can break XEmacs
 It has been reported on some systems that compiling with -O6 can lead
 to XEmacs failures.  The workaround is to use a lower optimization
 level.  -O2 and -O4 have been tested extensively.
 All of this depends heavily on the version of pgcc and the version
 of libc.  Snapshots near the release of pgcc-1.0 have been tested
 extensively and no sign of breakage has been seen on systems using
 glibc-2.
-*** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
+** `compress' and `uncompress' not found and XFree86
-This can happen if configure uses GNU sed version 2.03.  That version
-had a bug.  GNU sed version 2.05 works properly.
-*** When compiling with X11, you get "undefined symbol _XtStrings".
-This means that you are trying to link emacs against the X11r4 version of
-libXt.a, but you have compiled either Emacs or the code in the lwlib
-subdirectory with the X11r5 header files.  That doesn't work.
-Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
-They must be in sync.
-*** test-distrib says that the distribution has been clobbered
-or, temacs prints "Command key out of range 0-127"
-or, temacs runs and dumps xemacs, but xemacs totally fails to work.
-or, temacs gets errors dumping xemacs
-This can be because the .elc files have been garbled.  Do not be
-fooled by the fact that most of a .elc file is text: these are binary
-files and can contain all 256 byte values.
-In particular `shar' cannot be used for transmitting GNU Emacs.  It
-typically truncates "lines".  (this does not apply to GNU shar, which
-uses uuencode to encode binary files.)
-If you have a copy of Emacs that has been damaged in its nonprinting
-characters, you can fix them by running:
-make all-elc
-This will rebuild all the needed .elc files.
-*** `compress' and `uncompress' not found and XFree86
 XFree86 installs a very old version of libz.a by default ahead of where
 more modern version of libz might be installed.  This will cause problems
 when attempting to link against libMagick.  The fix is to remove the old
 libz.a in the X11 binary directory.
+** Excessive optimization on AIX 4.2 can lead to compiler failure.
-** AIX
-*** On AIX 4.3, you must specify --with-dialogs=athena with configure
-*** The libXt shipped with AIX 4.3 up to 4.3.2 is broken.  This causes
-xemacs -nw to fail in various ways.  The official APAR is this:
-APAR NUMBER: <IX89470>            RESOLVED AS: PROGRAM ERROR
-ABSTRACT:
-<IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT
-The solution is to install X11.base.lib at version >=4.3.2.5.
-*** On AIX, you get this compiler error message:
-Processing include file ./XMenuInt.h
-1501-106: (S) Include file X11/Xlib.h not found.
-This means your system was installed with only the X11 runtime i.d
-libraries.  You have to find your sipo (bootable tape) and install
-X11Dev... with smit.
-*** On AIX 4.1.2, linker error messages such as
-ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
-	 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
-This is a problem in libIM.a.  You can work around it by executing
-these shell commands in the src subdirectory of the directory where
-you build Emacs:
-cp /usr/lib/libIM.a .
-chmod 664 libIM.a
-ranlib libIM.a
-Then change -lIM to ./libIM.a in the command to link temacs (in
-Makefile).
-*** Excessive optimization on AIX 4.2 can lead to compiler failure.

 At least at the b34 level, and the latest-and-greatest IBM xlc
 (3.1.4.4), there are problems with -O3.  I haven't investigated
 further.
+** Sed problems on Solaris 2.5
-** SunOS/Solaris
-*** Dumping error when using GNU binutils / GNU ld on a Sun.
-Errors similar to the following:
-Dumping under the name xemacs unexec():
-dldump(/space/rpluim/xemacs-obj/src/xemacs): ld.so.1: ./temacs:
-fatal: /space/rpluim/xemacs-obj/src/xemacs: unknown dynamic entry:
-1879048176
-are caused by using GNU ld.  There are several workarounds available:
-In XEmacs 21.2 or later, configure using the new portable dumper
-(--pdump).
-Alternatively, you can link using the Sun version of ld, which is
-normally held in /usr/ccs/bin.  This can be done by one of:
-- building gcc with these configure flags:
-configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as
-- adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs
-(Note: The trailing '/' there is significant.)
-- uninstalling GNU ld.
-The Solaris2 FAQ claims:
-When you install gcc, don't make the mistake of installing
-GNU binutils or GNU libc, they are not as capable as their
-counterparts you get with Solaris 2.x.
-*** Link failure when using acc on a Sun.
-To use acc, you need additional options just before the libraries, such as
-/usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
-and you need to add -lansi just before -lc.
-The precise file names depend on the compiler version, so we
-cannot easily arrange to supply them.
-*** Problems finding X11 libraries on Solaris with Openwindows
-Some users have reported problems in this area.  The reported solution
-is to define the environment variable OPENWINHOME, even if you must set
-it to `/usr/openwin'.
-*** Sed problems on Solaris 2.5
 There have been reports of Sun sed truncating very lines in the
 Makefile during configuration.  The workaround is to use GNU sed or,
 even better, think of a better way to generate Makefile, and send us a
 patch. :-)

-ld: Undefined symbol
-_get_wmShellWidgetClass
+** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
-_get_applicationShellWidgetClass
-The fix to this is to install patch 100573 for OpenWindows 3.0
-or link libXmu statically.
-*** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
-This is the result of using cc or gcc with the shared library meant
-for acc (the Sunpro compiler).  Check your LD_LIBRARY_PATH and delete
-/usr/lang/SC2.0.1 or some similar directory.
-*** Undefined symbols when linking on Sunos 4.1.
-If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
-_iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
--lXaw in the command that links temacs.
-This problem seems to arise only when the international language
-extensions to X11R5 are installed.
-*** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
-/lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
-The problem is in the Sun shared C library, not in GNU ld.
-The solution is to install Patch-ID# 100267-03 from Sun.
-*** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
-Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
-some stuff that is in libXmu.a (the static version).  Sun has a patch for
-this, but a workaround is to use the static version of libXmu, by changing
-the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic".  If you have
-OpenWindows 3.0, ask Sun for these patches:
-100512-02       4.1.x OpenWindows 3.0 libXt Jumbo patch
-100573-03       4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
-*** Random other SunOS 4.1.[12] link errors.
-The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
-broken.  Use the ones in /usr/openwin/{include,lib} instead.
-** Linux
-*** Under Linux, you get "too many arguments to function `getpgrp'".
-You have probably installed LessTiff under `/usr/local' and `libXm.so'
-could not be found when linking `getpgrp()' test program, making XEmacs
-think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
-in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
-again.  As with all problems of this type, reading the config.log file
-generated from configure and seeing the log of how the test failed can
-prove enlightening.
-*** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
 This error message has been observed with lesstif-0.75a.  It does not
 appear to cause any harm.
-*** xemacs: can't resolve symbol '__malloc_hook'
+** Linking with -rpath on IRIX.
-This is a Linux problem where you've compiled the XEmacs binary on a libc
-5.4 with version higher than 5.4.19 and attempted to run the binary against
-an earlier version.  The solution is to upgrade your old library.
-** IRIX
-*** On Irix 6.5, the MIPSpro compiler gets an internal compiler error
-The MIPSpro Compiler (at least version 7.2.1) can't seem to handle the
-union type properly, and fails to compile src/glyphs.c.  To avoid this
-problem, always build ---use-union-type=3Dno (but that's the default, so
-you should only see this problem if you're an XEmacs maintainer).
-*** Linking with -rpath on IRIX.
 Darrell Kindred <dkindred@cmu.edu> writes:
 There are a couple of problems [with use of -rpath with Irix ld], though:
 1. The ld in IRIX 5.3 ignores all but the last -rpath
 rather than quoting $LDFLAGS with prefix-args, like
 src/Makefile does.  So if you specify --x-libraries
 or --site-runtime-libraries, you must use --use-gcc=no,
 or configure will fail.

+** C-z just refreshes the screen instead of suspending Emacs.
 You are probably using a shell that doesn't support job control, even
 though the system itself is capable of it.  Try using a different
 shell.
-*** You type Control-H (Backspace) expecting to delete characters.
+** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
+/lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
+The problem is in the Sun shared C library, not in GNU ld.
+The solution is to install Patch-ID# 100267-03 from Sun.
+** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
+Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
+some stuff that is in libXmu.a (the static version).  Sun has a patch for
+this, but a workaround is to use the static version of libXmu, by changing
+the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic".  If you have
+OpenWindows 3.0, ask Sun for these patches:

+** Random other SunOS 4.1.[12] link errors.
+The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
+broken.  Use the ones in /usr/openwin/{include,lib} instead.
+** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
+When using gcc, you get the error message "undefined symbol __main".
+This means that you need to link with the gcc library.  It may be called
+"gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
+config.h to point to it.
+It may also work to use the GCC version of `ld' instead of the standard one.
+** When compiling with X11, you get "undefined symbol _XtStrings".
+This means that you are trying to link emacs against the X11r4 version of
+libXt.a, but you have compiled either Emacs or the code in the lwlib
+subdirectory with the X11r5 header files.  That doesn't work.
+Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
+They must be in sync.
+** Problems finding X11 libraries on Solaris with Openwindows
+Some users have reported problems in this area.  The reported solution
+is to define the environment variable OPENWINHOME, even if you must set
+it to `/usr/openwin'.
+** Under Linux, you get "too many arguments to function `getpgrp'".
+You have probably installed LessTiff under `/usr/local' and `libXm.so'
+could not be found when linking `getpgrp()' test program, making XEmacs
+think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
+in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
+again.  As with all problems of this type, reading the config.log file
+generated from configure and seeing the log of how the test failed can
+prove enlightening.
+* Problems with running XEmacs
+==============================
+** On Solaris 2.6, XEmacs dumps core when exiting.
+This happens if you're XEmacs is running on the same machine as the X
+server, and the optimized memory transport has been turned on by
+setting the environment variable XSUNTRANSPORT.  The crash occurs
+during the call to XCloseDisplay.
+If this describes your situation, you need to undefine the
+XSUNTRANSPORT environment variable.
+** `C-z', or `M-x suspend-emacs' hangs instead of suspending.
+If you build with `gpm' support on Linux, you cannot suspend XEmacs
+because gpm installs a buggy SIGTSTP handler.  Either compile with
+`--with-gpm=no', or don't suspend XEmacs on the Linux console until
+this bug is fixed.
+** You type Control-H (Backspace) expecting to delete characters.
 Emacs has traditionally used Control-H for help; unfortunately this
-interferes with its use as Backspace on TTY's.  As of XEmacs 21,
+interferes with its use as Backspace on TTY's.  One way to solve this
-XEmacs looks at the "erase" setting of TTY structures and maps C-h to
+problem is to put this in your .emacs:
-backspace when erase is set to C-h.  This is sort of a special hack,
-but it makes it possible for you to use the standard:

+Note that you can probably also access help using F1.
-A major drawback of this is that when C-h becomes backspace, it no
-longer invokes help.  In that case, you need to use f1 for help, or

-bind another key.  An example of the latter is the following code,
-which moves help to Meta-? (ESC ?):
-(global-set-key "\M-?" 'help-command)
-*** Mail agents (VM, Gnus, rmail) cannot get new mail
 rmail and VM get new mail from /usr/spool/mail/$USER using a program
 called `movemail'.  This program interlocks with /bin/mail using the
 protocol defined by /bin/mail.
 installed copy of movemail is usually in the directory
 /usr/local/lib/emacs/VERSION/TARGET.  You must change the group and
 mode of the installed copy; changing the group and mode of the build
 directory copy is ineffective.
-*** VM appears to hang in large folders.
+** XEmacs crashes on Digital Unix within font-lock, or when dealing
+with large compilation buffers.
+The default stack size under Digital Unix is rather small (2M as
+opposed to Solaris 8M), hosing the regexp code, which uses alloca()
+extensively, overflowing the stack when complex regexps are used.
+Workarounds:
+1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
+equivalent;
+2) Recompile regex.c with REGEX_MALLOC defined.
+** On Solaris, C-x doesn't get through to Emacs when you use the console.
+This is a Solaris feature (at least on Intel x86 cpus).  Type C-r
+C-r C-t, to toggle whether C-x gets through to Emacs.
+** VM appears to hang in large folders.
 This is normal (trust us) when upgrading to VM-6.22 from earlier
 versions.  Let VM finish what it is doing and all will be well.
-*** Changes made to .el files do not take effect.
+** Changes made to .el files do not take effect.
 You may have forgotten to recompile them into .elc files.  Then the
 old .elc files will be loaded, and your changes will not be seen.  To
 fix this, do `M-x byte-recompile-directory' and specify the directory
 that contains the Lisp files.
 Note that you will get a warning when loading a .elc file that is
 older than the corresponding .el file.

 copyright notice) are not.
 The fonts of the "bold" and "italic" faces are generated from the font
 of the "default" face; in this way, your bold and italic fonts will
 have the appropriate size and family.  However, emacs can only be
 then emacs won't be able to guess the names of the "bold" and "italic"
 versions.  All X fonts can be referred to via XLFD-style names, so you
 should use those forms.  See the man pages for X(1), xlsfonts(1), and
 xfontsel(1).
-*** The dumped Emacs crashes when run, trying to write pure data.
+** The dumped Emacs crashes when run, trying to write pure data.
 Two causes have been seen for such problems.
 1) On a system where getpagesize is not a system call, it is defined
 as a macro.  If the definition (in both unexec.c and malloc.c) is wrong,
 initialized variables.  Emacs makes all initialized variables in most
 of its files pure after dumping, but the variables declared static and
 not initialized are not supposed to be pure.  On these systems you
 may need to add "#define static" to the m- or the s- file.
-*** Reading and writing files is very very slow.
+** Reading and writing files is very very slow.
 Try evaluating the form (setq lock-directory nil) and see if that helps.
 There is a problem with file-locking on some systems (possibly related
 to NFS) that I don't understand.  Please send mail to the address
 xemacs@xemacs.org if you figure this one out.
-*** When emacs starts up, I get lots of warnings about unknown keysyms.
+** The Emacs window disappears when you type M-q.
+Some versions of the Open Look window manager interpret M-q as a quit
+command for whatever window you are typing at.  If you want to use
+Emacs with that window manager, you should try to configure the window
+manager to use some other command.   You can disable the
+shortcut keys entirely by adding this line to ~/.OWdefaults:
+OpenWindows.WindowMenuAccelerators: False
+** The `Alt' key doesn't behave as `Meta' when running DECwindows.
+The default DEC keyboard mapping has the Alt keys set up to generate the
+keysym `Multi_key', which has a meaning to xemacs which is distinct from that
+of the `Meta_L' and `Meta-R' keysyms.  A second problem is that certain keys
+have the Mod2 modifier attached to them for no adequately explored reason.
+The correct fix is to pass this file to xmodmap upon starting X:
+	clear mod2
+	keysym Multi_key = Alt_L
+	add mod1 = Alt_L
+	add mod1 = Alt_R
+** The Compose key on a DEC keyboard does not work as Meta key.
+This shell command should fix it:
+xmodmap -e 'keycode 0xb1 = Meta_L'
+** When emacs starts up, I get lots of warnings about unknown keysyms.
 If you are running the prebuilt binaries, the Motif library expects to find
 certain thing in the XKeysymDB file.  This file is normally in /usr/lib/X11/
 or in /usr/openwin/lib/.  If you keep yours in a different place, set the
 environment variable $XKEYSYMDB to point to it before starting emacs.  If
 you still have the problem after doing that, perhaps your version of X is
 too old.  There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
 directory.  Try using that one.
-*** My X resources used to work, and now some of them are being ignored.
+** My X resources used to work, and now some of them are being ignored.
 Check the resources in .../etc/Emacs.ad (which is the same as the file
 sample.Xdefaults).  Perhaps some of the default resources built in to
 emacs are now overriding your existing resources.  Copy and edit the
 resources in Emacs.ad as necessary.
-*** I have focus problems when I use `M-o' to switch to another screen
+** I get complaints about the mapping of my HP keyboard at startup,
+but I haven't changed anything.
+The default HP keymap is set up to have Mod1 assigned to two different keys:
+Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
+the keyboard -- it uses an "imaginary" keycode.)  There actually is a reason
+for this, but it's not a good one.  The correct fix is to execute this command
+upon starting X:
+	xmodmap -e 'remove mod1 = Mode_switch'
+** I have focus problems when I use `M-o' to switch to another screen
 without using the mouse.
 The focus issues with a program like XEmacs, which has multiple
 homogeneous top-level windows, are very complicated, and as a result,
 most window managers don't implement them correctly.
 (Many people suggest that XEmacs should warp the mouse when focusing
 on another screen in point-to-type mode.  This is not ICCCM-compliant
 behavior.  Implementing such policy is the responsibility of the
 window manager itself, it is not legal for a client to do this.)
-*** Emacs spontaneously displays "I-search: " at the bottom of the screen.
+** Emacs spontaneously displays "I-search: " at the bottom of the screen.
 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
 used.  C-s/C-q flow control is bad for Emacs editors because it takes
 away C-s and C-q as user commands.  Since editors do not output long
 streams of text without user commands, there is no need for a
 widespread, XON/XOFF seems to be on the way out.  If you can get some
 use out of GNU Emacs on inferior terminals, more power to you, but I
 will not make Emacs worse for properly designed systems for the sake
 of inferior systems.
-*** Control-S and Control-Q commands are ignored completely.
+** Control-S and Control-Q commands are ignored completely.
 For some reason, your system is using brain-damaged C-s/C-q flow
 control despite Emacs's attempts to turn it off.  Perhaps your
 terminal is connected to the computer through a concentrator
 that wants to use flow control.
 If that line of approach is not successful, map some other characters
 into C-s and C-q using keyboard-translate-table.  The example above
 shows how to do this with C-^ and C-\.
-*** Control-S and Control-Q commands are ignored completely on a net
+** Control-S and Control-Q commands are ignored completely on a net
 connection.
 Some versions of rlogin (and possibly telnet) do not pass flow
 control characters to the remote system to which they connect.
 On such systems, emacs on the remote system cannot disable flow
 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
 See the entry about spontaneous display of I-search (above) for more
 info.
-*** TTY redisplay is slow.
+** TTY redisplay is slow.
 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
 which doesn't include some basic TTY optimizations -- like using
 scrolling regions to move around blocks of text.  This is why
 redisplay on the traditional terminals, or over slow lines can be very
 slow.
 If you are interested in fixing this, please let us know at
 <xemacs@xemacs.org>.
-*** Screen is updated wrong, but only on one kind of terminal.
+** Screen is updated wrong, but only on one kind of terminal.
 This could mean that the termcap entry you are using for that terminal
 is wrong, or it could mean that Emacs has a bug handing the
 combination of features specified for that terminal.
 This is unambiguously an Emacs bug, and can probably be fixed in
 termcap.c, terminfo.c, tparam.c, cm.c, redisplay-tty.c,
 redisplay-output.c, or redisplay.c.
-*** My buffers are full of \000 characters or otherwise corrupt.
+** Your Delete key sends a Backspace to the terminal, using an AIXterm.
-Some compilers have trouble with gmalloc.c and ralloc.c; try recompiling
-without optimization.  If that doesn't work, try recompiling with
-SYSTEM_MALLOC defined, and/or with REL_ALLOC undefined.
-*** A position you specified in .Xdefaults is ignored, using twm.
-twm normally ignores "program-specified" positions.
-You can tell it to obey them with this command in your `.twmrc' file:
-UsePPosition	"on"		#allow clents to request a position
-*** With M-x enable-flow-control, you need to type C-\ twice to do
-incremental search--a single C-\ gets no response.
-This has been traced to communicating with your machine via kermit,
-with C-\ as the kermit escape character.  One solution is to use
-another escape character in kermit.  One user did
-set escape-character 17
-in his .kermrc file, to make C-q the kermit escape character.
-*** The Motif version of Emacs paints the screen a solid color.
-This has been observed to result from the following X resource:
-Emacs*default.attributeFont:	-*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*
-That the resource has this effect indicates a bug in something, but we
-do not yet know what.  If it is an Emacs bug, we hope someone can
-explain what the bug is so we can fix it.  In the mean time, removing
-the resource prevents the problem.
-*** After running emacs once, subsequent invocations crash.
-Some versions of SVR4 have a serious bug in the implementation of the
-mmap () system call in the kernel; this causes emacs to run correctly
-the first time, and then crash when run a second time.
-Contact your vendor and ask for the mmap bug fix; in the mean time,
-you may be able to work around the problem by adding a line to your
-operating system description file (whose name is reported by the
-configure script) that reads:
-#define SYSTEM_MALLOC
-This makes Emacs use memory less efficiently, but seems to work around
-the kernel bug.
-*** Inability to send an Alt-modified key, when Emacs is communicating
-directly with an X server.
-If you have tried to bind an Alt-modified key as a command, and it
-does not work to type the command, the first thing you should check is
-whether the key is getting through to Emacs.  To do this, type C-h c
-followed by the Alt-modified key.  C-h c should say what kind of event
-it read.  If it says it read an Alt-modified key, then make sure you
-have made the key binding correctly.
-If C-h c reports an event that doesn't have the Alt modifier, it may
-be because your X server has no key for the Alt modifier.  The X
-server that comes from MIT does not set up the Alt modifier by
-default.
-If your keyboard has keys named Alt, you can enable them as follows:
-xmodmap -e 'add mod2 = Alt_L'
-xmodmap -e 'add mod2 = Alt_R'
-If the keyboard has just one key named Alt, then only one of those
-commands is needed.  The modifier `mod2' is a reasonable choice if you
-are using an unmodified MIT version of X.  Otherwise, choose any
-modifier bit not otherwise used.
-If your keyboard does not have keys named Alt, you can use some other
-keys.  Use the keysym command in xmodmap to turn a function key (or
-some other 'spare' key) into Alt_L or into Alt_R, and then use the
-commands show above to make them modifier keys.
-Note that if you have Alt keys but no Meta keys, Emacs translates Alt
-into Meta.  This is because of the great importance of Meta in Emacs.
-*** In Shell mode, you get a ^M at the end of every line.
-This happens to people who use tcsh, because it is trying to be too
-smart.  It sees that the Shell uses terminal type `unknown' and turns
-on the flag to output ^M at the end of each line.  You can fix the
-problem by adding this to your .cshrc file:
-if ($?EMACS) then
-if ($EMACS == "t") then
-unset edit
-stty  -icrnl -onlcr -echo susp ^Z
-endif
-endif
-*** An error message such as `X protocol error: BadMatch (invalid
-parameter attributes) on protocol request 93'.
-This comes from having an invalid X resource, such as
-emacs*Cursor:   black
-(which is invalid because it specifies a color name for something
-that isn't a color.)
-The fix is to correct your X resources.
-*** Once you pull down a menu from the menubar, it won't go away.
-It has been claimed that this is caused by a bug in certain very old
-(1990?)  versions of the twm window manager.  It doesn't happen with
-recent vintages, or with other window managers.
-*** Emacs ignores the "help" key when running OLWM.
-OLWM grabs the help key, and retransmits it to the appropriate client
-using XSendEvent.  Allowing emacs to react to synthetic events is a
-security hole, so this is turned off by default.  You can enable it by
-setting the variable x-allow-sendevents to t.  You can also cause fix
-this by telling OLWM to not grab the help key, with the null binding
-"OpenWindows.KeyboardCommand.Help:".
-*** Programs running under terminal emulator do not recognize `emacs'
-terminal type.
-The cause of this is a shell startup file that sets the TERMCAP
-environment variable.  The terminal emulator uses that variable to
-provide the information on the special terminal type that Emacs
-emulates.
-Rewrite your shell startup file so that it does not change TERMCAP
-in such a case.  You could use the following conditional which sets
-it only if it is undefined.
-if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
-Or you could set TERMCAP only when you set TERM--which should not
-happen in a non-login shell.
-*** The popup menu appears at the bottom/right of my screen.
-You probably have something like the following in your ~/.Xdefaults

-*** Your Delete key sends a Backspace to the terminal, using an AIXterm.
 The solution is to include in your .Xdefaults the lines:
 *aixterm.Translations: #override <Key>BackSpace: string(0x7f)
 aixterm*ttyModes: erase ^?
 This makes your Backspace key send DEL (ASCII 127).

+*** Non-Networked Case
+The solution described in the networked case applies here as well.
+However, if you never intend to network your machine, you can use a
+simpler solution: create an empty `/etc/host.conf' file.  The command

+you may be able to work around the problem by adding a line to your

+This makes Emacs use memory less efficiently, but seems to work around
+the kernel bug.
+** Inability to send an Alt-modified key, when Emacs is communicating
+directly with an X server.
+If you have tried to bind an Alt-modified key as a command, and it
+does not work to type the command, the first thing you should check is
+whether the key is getting through to Emacs.  To do this, type C-h c
+followed by the Alt-modified key.  C-h c should say what kind of event
+it read.  If it says it read an Alt-modified key, then make sure you
+have made the key binding correctly.
+If C-h c reports an event that doesn't have the Alt modifier, it may
+be because your X server has no key for the Alt modifier.  The X
+server that comes from MIT does not set up the Alt modifier by
+default.
+If your keyboard has keys named Alt, you can enable them as follows:
+xmodmap -e 'add mod2 = Alt_L'
+xmodmap -e 'add mod2 = Alt_R'
+If the keyboard has just one key named Alt, then only one of those
+commands is needed.  The modifier `mod2' is a reasonable choice if you
+are using an unmodified MIT version of X.  Otherwise, choose any
+modifier bit not otherwise used.
+If your keyboard does not have keys named Alt, you can use some other
+keys.  Use the keysym command in xmodmap to turn a function key (or
+some other 'spare' key) into Alt_L or into Alt_R, and then use the
+commands show above to make them modifier keys.
+Note that if you have Alt keys but no Meta keys, Emacs translates Alt
+into Meta.  This is because of the great importance of Meta in Emacs.
+** `Pid xxx killed due to text modification or page I/O error'
+On HP/UX, you can get that error when the Emacs executable is on an NFS
+file system.  HP/UX responds this way if it tries to swap in a page and
+does not get a response from the server within a timeout whose default
+value is just ten seconds.
+If this happens to you, extend the timeout period.
+** `expand-file-name' fails to work on any but the machine you dumped
+Emacs on.
+On Ultrix, if you use any of the functions which look up information
+in the passwd database before dumping Emacs (say, by using
+expand-file-name in site-init.el), then those functions will not work
+in the dumped Emacs on any host but the one Emacs was dumped on.
+The solution?  Don't use expand-file-name in site-init.el, or in
+anything it loads.  Yuck - some solution.
+I'm not sure why this happens; if you can find out exactly what is
+going on, and perhaps find a fix or a workaround, please let us know.

+The problem is that in your .cshrc you have something that tries to
+execute `tty`. If you are not running the shell on a real tty then tty
+will print "not a tty". Csh expects one word in some places, but tty

+The solution is to add a pair of quotes around `tty` to make it a

+Even better, move things that set up terminal sections out of .cshrc
+and into .login.
+** With process-connection-type set to t, each line of subprocess
 output is terminated with a ^M, making ange-ftp and GNUS not work.
 On SunOS systems, this problem has been seen to be a result of an
 incomplete installation of gcc 2.2 which allowed some non-ANSI

-*** XEmacs dumps core at startup when native audio is used.  Native
-audio does not work with recent versions of HP-UX.
-Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio
-enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if
-recent versions of the libAlib.sl audio shared library is used.  Note
-that "temacs" will run, but "xemacs" will dump core.  This, of course,
-causes the XEmacs build to fail.  If GNU malloc is enabled, a stack
-trace will show XEmacs to have crashed in the "first" call to malloc().
-This bug currently exists in all versions of XEmacs, when the undump
-mechanism is used.  It is not known if using the experimental portable
-dumper will allow native audio to work.
-**** Cause:
-Recent versions of the HP-UX 10.20 (and later) audio shared library (in
-/opt/audio/lib), pulls in the libdce shared library, which pulls in a
-thread (libcma) library.  This prevents the HP-UX undump() routine (in
-unexhp9k800.c) from properly working.  What's happening is that some
-initialization routines are being called in the libcma library, *BEFORE*
-main() is called, and these initialization routines are calling
-malloc().  Unfortunately, in order for the undumper to work, XEmacs must
-adjust (move upwards) the sbrk() value *BEFORE* the first call to
-malloc(); if malloc() is called before XEmacs has properly adjusted sbrk
-(which is what is happening), dumped memory that is being used by
-XEmacs, is improperly re-allocated for use by malloc() and the dumped
-memory is corrupted.  This causes XEmacs to die an horrible death.
-It is believed that versions of the audio library past December 1998
-will trigger this problem.  Under HP-UX 10.20, you probably have to
-install audio library patches to encounter this.  It's probable that
-recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this
-problem.  For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or
-a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481,
-or PHSS_21662, etc.) will trigger this.
-To check if your audio library will cause problems for XEmacs, run
-"chatr /opt/audio/lib/libAlib.sl".  If "libdce" appears in the displayed
-shared library list, XEmacs will probably encounter problems if audio is
-enabled.
-**** Workaround:
-Don't enable native audio.  Re-run configure without native audio
-support.
-If your site supports it, try using NAS (Network Audio Support).
-Try using the experimental portable dumper.  It may work, or it may
-not.
