[xemacs-hg @ 2003-03-02 02:18:05 by ben] To: xemacs-patches@xemacs.org PROBLEMS: Include nt/PROBLEMS and update. Add note about incremental linking badness. cmdloop.el, custom.el, dumped-lisp.el, files.el, keydefs.el, keymap.el, lisp-mode.el, make-docfile.el, replace.el, simple.el, subr.el, view-less.el, wid-edit.el: Lots of syncing with FSF 21.2. Use if-fboundp in wid-edit.el. New file newcomment.el from FSF. internals/internals.texi: Fix typo. (Build-Time Dependencies): New node. PROBLEMS: Delete. config.inc.samp, xemacs.mak: Eliminate HAVE_VC6, use SUPPORT_EDIT_AND_CONTINUE in its place. No incremental linking unless SUPPORT_EDIT_AND_CONTINUE, since it can cause nasty crashes in pdump. Put warnings about this in config.inc.samp. Report the full compile flags used for src and lib-src in the Installation output. alloc.c, lisp.h, ralloc.c, regex.c: Use ALLOCA() in regex.c to avoid excessive stack allocation. Also fix subtle problem with REL_ALLOC() -- any call to malloc() (direct or indirect) may relocate rel-alloced data, causing buffer text to shift. After any such call, regex must update all its pointers to such data. Add a system, when ERROR_CHECK_MALLOC, whereby regex.c indicates all the places it is prepared to handle malloc()/realloc()/free(), and any calls anywhere in XEmacs outside of this will trigger an abort. alloc.c, dialog-msw.c, eval.c, event-stream.c, general-slots.h, insdel.c, lisp.h, menubar-msw.c, menubar-x.c: Change *run_hook*_trapping_problems to take a warning class, not a string. Factor out code to issue warnings, add flag to call_trapping_problems() to postpone warning issue, and make *run_hook*_trapping_problems issue their own warnings tailored to the hook, postponed in the case of safe_run_hook_trapping_problems() so that the appropriate message can be issued about resetting to nil only when not `quit'. Make record_unwind_protect_restoring_int() non-static. dumper.c: Issue notes about incremental linking problems under Windows. fileio.c: Mule-ize encrypt/decrypt-string code. text.h: Spacing changes.

-problem still exists.  Also ask on xemacs-nt@xemacs.org.
+*** Conflicts with FSF NTEmacs
+
+Depending on how it is installed, FSF NTEmacs may setup various EMACS*
+variables in your environment.  The presence of these variables may
+cause XEmacs to fail at startup, cause you to see corrupted
+doc-strings, or cause other random problems.
+
+You should remove these variables from your environment.  These
+variables are not required to run FSF NTEmacs if you start it by
+running emacs.bat.
+
+*** XEmacs can't find my init file
+
+XEmacs looks for your init in your "home" directory -- either in
+`~/.xemacs/init.el' or `~/.emacs'.  XEmacs decides that your "home"
+directory is, in order of preference:
+	
+- The value of the HOME environment variable, if the variable exists.
+- The value of the registry entry SOFTWARE\XEmacs\XEmacs\HOME,
+  if it exists.
+- The value of the HOMEDRIVE and HOMEPATH environment variables, if
+  these variables both exist.
+- C:\.
+
+To determine what XEmacs thinks your home directory is, try opening
+a file in the `~' directory, and you should see its expansion in the
+modeline.  If this doesn't work, type ESC : (user-home-directory).
+
+*** XEmacs can't find any packages
+
+XEmacs looks for your packages in subdirectories of a directory which
+is set at compile-time (see `config.inc'), and whose default is
+`C:\Program Files\XEmacs'.  XEmacs also looks in `~/.xemacs', where
+`~' refers to your home directory (see previous entry).  The variable
+`configure-package-path' holds the actual path that was compiled into
+your copy of XEmacs.
+
+The compile-time default location can be overridden by the EMACSPACKAGEPATH
+environment variable or by the SOFTWARE\XEmacs\XEmacs\EMACSPACKAGEPATH
+registry entry.  You should check that these variables, if they exist,
+point to the actual location of your package tree.
+
+*** XEmacs doesn't die when shutting down Windows 95 or 98
+
+When shutting down Windows 95 or 98 you may see a dialog that says
+  "xemacs / You must quit this program before you quit Windows".
+It is safe to
+  "Click OK to quit the program and Windows",
+but you won't be offered a chance to save any modified XEmacs buffers.
+
+*** Key bindings
+
+The C-z, C-x, C-c, and C-v keystrokes have traditional uses in both
+emacs and Windows programs. XEmacs binds these keys to their
+traditional emacs uses, and provides Windows 3.x style bindings for
+the Cut, Copy and Paste functions.
+
+	Function	XEmacs binding
+	--------	--------------
+	Undo		C-_
+	Cut		Sh-Del
+ 	Copy		C-Insert
+	Paste		Sh-Insert
+
+You can rebind keys to make XEmacs more Windows-compatible; for
+example, to bind C-z to undo:
+
+       (global-set-key [(control z)] 'undo)
+
+Rebindind C-x and C-c is trickier because by default these are prefix
+keys in XEmacs. See the "Key Bindings" node in the XEmacs manual.
+
+*** Behavior of selected regions
+
+Use the pending-del package to enable the standard Windows behavior of
+self-inserting deletes region.
+
+*** Limitations on the use of the AltGr key.
+
+In some locale and OS combinations you can't generate M-AltGr-key or
+C-M-AltGr-key sequences at all.
+
+To generate C-AltGr-key or C-M-AltGr-key sequences you must use the
+right-hand Control key and you must press it *after* AltGr.
+
+These limitations arise from fundamental problems in the way that the
+win32 API reports AltGr key events. There isn't anything that XEmacs
+can do to work round these problems that it isn't already doing.
+
+You may want to create alternative bindings if any of the standard
+XEmacs bindings require you to use some combination of Control or Meta
+and AltGr.
+
+*** Limited support for subprocesses under Windows 9x
+
+Attempting to use call-process to run a 16bit program gives a
+"Spawning child process: Exec format error". For example shell-command
+fails under Windows 95 and 98 if you use command.com or any other
+16bit program as your shell.
+
+XEmacs may incorrectly quote your call-process command if it contains
+double quotes, backslashes or spaces.
+
+start-process and functions that rely on it are supported under Windows 95,
+98 and NT. However, starting a 16bit program that requires keyboard input
+may cause XEmacs to hang or crash under Windows 95 and 98, and will leave
+the orphaned 16bit program consuming all available CPU time.
+
+Sending signals to subprocesses started by call-process or by
+start-process fails with a "Cannot send signal to process" error under
+Windows 95 and 98. As a side effect of this, quitting XEmacs while it
+is still running subprocesses causes it to crash under Windows 95 and
+98.
