Here's the list of these optional libraries, and the URLs where they
can be found:
To take proper advantage of Emacs 21's mule-unicode charsets, you need
a Unicode font. For information on Unicode fonts for X, see

ISO-8859 charsets.

BUILDING GNU EMACS BY HAND
(see below) will test for these utilities and will refuse to continue
if any of them isn't found.
+Recompiling Lisp files in the `lisp' subdirectory using the various
+targets in the lisp/Makefile file requires additional utilities:
+`find' and `xargs' (from Findutils), `touch' (from Fileutils) GNU
+`echo' and `test' (from Sh-utils), `tr, `sort', and `uniq' (from
+Textutils), and a port of Bash. However, you should not normally need
+to run lisp/Makefile, as all the Lisp files are distributed in
+byte-compiled form as well.

If you are building the MSDOG version of Emacs on an MSDOG-like system
which supports long file names (e.g. Windows 95), you need to make
sure that long file names are handled consistently both when you
should be able to find them in your djdevNNN.zip archive (where NNN is
the DJGPP version number).
+On Windows NT or Windows 2000, running "config msdos" might print an
+error message like "VDM has been already loaded". This is because
+those systems have a program called `redir.exe' which is incompatible
+with a program by the same name supplied with DJGPP, which is used by
+config.bat. To resolve this, move the DJGPP's `bin' subdirectory to
+the front of your PATH environment variable.

To install the international fonts, chdir to the intlfonts-X.Y
directory created when you unpacked the intlfonts distribution (X.Y is
the version number of the fonts' distribution), and type the following
