-This is a result of an internationalization extension in X11R4 and the
-fact that HP is now using this extension.  Emacs assumes that the
-@code{XLookupString} function returns the same result regardless of the
-@key{Meta} key state which is no longer necessarily true.  Until Emacs
-is fixed, the temporary kludge is to run this command after each time
-the X server is started but preferably before any xterm clients are:
-
-@example
-xmodmap -e 'remove mod1 = Mode_switch'
-@end example

-@c FIXME: Emacs 21 supports I18N in X11; does that mean that this bug is

-This will disable the use of the extra keysyms systemwide, which may be
-undesirable if you actually intend to use them.
