+ 4.1.0 can crash Emacs.
Emacs will configure itself to build with these libraries if the
`configure' script finds them on your system, unless you supply the
configure should avoid such old versions. If that happens, use the
--without-LIB options to `configure'. See below for more details.
+* Extra fonts
+
+To take proper advantage of Emacs 21's mule-unicode charsets, you need
+a Unicode font. For information on Unicode fonts for X, see
+<URL:http://czyborra.com/unifont/> and
+<URL:http://www.cl.cam.ac.uk/%7Emgk25/ucs-fonts.html>.
+<URL:http://czyborra.com/charsets/> has basic fonts for Emacs's
+ISO-8859 charsets.
+
+XFree86 release 4 (from <URL:ftp://ftp.xfree86.org/> and mirrors)
+contains font support for most, if not all, of the charsets that Emacs
+supports. The font files should be usable separately with older X
+releases.

DETAILED BUILDING AND INSTALLATION:
TOOLKIT is `athena' or `motif' (`yes' and `lucid' are synonyms for
`athena'). On some systems, it does not work to use a toolkit with
shared libraries. A free implementation of Motif, called LessTif, is
-available ftom <http://www.lesstif.org>. You can get fancy 3D-style
-scroll bars, even without LessTif/Motif, if you have the Xaw3d library
+available ftom <http://www.lesstif.org>. Compiling with LessTif or
+Motif causes a standard File Selection Dialog to pop up when you type
+"C-x C-f" and similar commands. You can get fancy 3D-style scroll
+bars, even without LessTif/Motif, if you have the Xaw3d library
installed (see "Image support libraries" above for Xaw3d
availability).
