* Image support libraries
Emacs needs optional libraries to be able to display images (with the
-exception of PBM images whose support is built-in). Here's the list
-of these optional libraries, and the URLs where they can be found:
+exception of PBM and XBM images whose support is built-in). On some
+systems these may already be present or available as additional
+packages, particularly on GNU/Linux. (In some cases older versions
+won't work because some routines are missing, and configure should
+avoid such old versions.)
+
+If necessary, you can build them from source. None are vital for
+running Emacs. Here's the list of these optional libraries, and the
+URLs where they can be found:
. libxpm for XPM: ftp://ftp.x.org/contrib/libraries/
. libpng for PNG: ftp://www.libpng.org/pub/png/
- . Zlib (for PNG): http://www.info-zip.org/pub/infozip/zlib/
+ . libz (for PNG): http://www.info-zip.org/pub/infozip/zlib/
. libjpeg for JPEG: ftp://ftp.uu.net/graphics/jpeg/
. libtiff for TIFF: http://www.libtiff.org/
. libungif for GIF:

-Emacs needs to be configured with the appropriate --with-LIB option,
-to be built with these libraries. See below for more details.
+[libungif-4.1.0 can crash Emacs with uncompressed GIFs -- use
+libungif-4.1.0b1.]
+
+Emacs will configure itself to build with these libraries if configure
+finds them on your system unless you supply the appropriate
+--without-LIB option. See below for more details.
BUILDING AND INSTALLATION:
`--with-gcc=no'. If you omit this option, `configure' will search
for GCC in your path, and use it if present.
-If you want the Emacs mail reader RMAIL to read mail from a POP
-server, you must specify `--with-pop'. This provides support for the
-POP3 protocol; older versions are not supported. For
-Kerberos-authenticated POP add `--with-kerberos', for Hesiod support
-add `--with-hesiod'. These options enable Emacs to use POP; whether
-Emacs uses POP is controlled by individual users--see the Rmail
-chapter of the Emacs manual.
+The Emacs mail reader RMAIL is configured to be able to read mail from
+a POP3 server by default. Versions of the POP protocol older than
+POP3 are not supported. For Kerberos-authenticated POP add
+`--with-kerberos', for Hesiod support add `--with-hesiod'. While POP3
+is always enabled, whether Emacs actually uses POP is controlled by
+individual users--see the Rmail chapter of the Emacs manual.
-To get Emacs with image support, configure with one or more of these
-options:
+For image support you may have to download, build, and install the
+appropriate image support libraries for image types other than XBM and
+PBM, see the list of URLs in "ADDITIONAL DISTRIBUTION FILES" above.
+(Note that PNG support requires libz in addition to libpng.)
- --with-xpm for XPM image support
- --with-jpeg for JPEG image support
- --with-tiff for TIFF image support
- --with-gif for GIF image support
- --with-png for PNG image support
+To disable individual types of image support in Emacs for some reason,
+even though configure finds the libraries, you can configure with one
+or more of these options:
-You will have to download, build, and install the appropriate image
-support libraries, see the list of URLs in "ADDITIONAL DISTRIBUTION
-FILES" above. (Note that configuring --with-png requires Zlib in
-addition to libpng.)
+ --without-xpm for XPM image support
+ --without-jpeg for JPEG image support
+ --without-tiff for TIFF image support
+ --without-gif for GIF image support
+ --without-png for PNG image support
The `--prefix=PREFIXDIR' option specifies where the installation process
should put emacs and its data files. This defaults to `/usr/local'.
config msdos
make install
+Running "config msdos" checks for several programs that are required
+to configure and build Emacs; if one of those programs is not found,
+CONFIG.BAT stops and prints an error message. If you have DJGPP
+version 2.0 or 2.01, it will complain about a program called
+DJECHO.EXE. These old versions of DJGPP shipped that program under
+the name ECHO.EXE, so you can simply copy ECHO.EXE to DJECHO.EXE and
+rerun CONFIG.BAT. If you have neither ECHO.EXE nor DJECHO.EXE, you
+should be able to find them in your djdevNNN.zip archive (where NNN is
+the DJGPP version number).

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
