*** 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. One way to solve this
-problem is to put this in your .emacs:
+interferes with its use as Backspace on TTY's. As of XEmacs 21,
+XEmacs looks at the "erase" setting of TTY structures and maps C-h to
+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:
- (when (eq tty-erase-char ?\C-h)
- (keyboard-translate ?\C-h ?\C-?)
- (global-set-key "\M-?" 'help-command))
+ stty erase ^H
-This checks whether the TTY erase char is C-h, and if it is, makes
-Control-H (Backspace) work sensibly, and moves help to Meta-? (ESC ?).
+to get your backspace key to erase characters. The erase setting is
+recorded in the Lisp variable `tty-erase-char', which you can use to
+tune the settings in your .emacs.
-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)

+*** 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.
