annotate src/iso-wide.h @ 622:11502791fc1c

[xemacs-hg @ 2001-06-22 01:49:57 by ben] dired-msw.c: Fix problem noted by Michael Sperber with directories containing [] and code that destructively modifies an existing string. term\AT386.el: Fix warnings. term\apollo.el: Removed. Kill kill kill. Sync with FSF and remove most crap. term\linux.el: Removed. Sync with FSF. Don't define most defns, because they are automatically defined by termcap. But do add defns for keys that normally get defined as f13, f14, etc. and really ought to be shift-f3, shift-f4, etc. (NOTE: I did this based on Cygwin, which emulates the Linux console. I would appreciate it if someone on Linux could verify.) term\cygwin.el: New. Load term/linux. term\lk201.el, term\news.el, term\vt100.el: Sync with FSF. Fix warnings. dialog-gtk.el: Fix warning. For 21.4: help.el, update-elc.el: Compile in proper order. Maybe for 21.4: keydefs.el: Add a defn for M-?, previously undefined, to access help -- in case the terminal is not set up right, or f1 gets redefined. README: Rewrite.
