-If you are compiling on an MSDOG-like system which has long file
-names, you may need to do `SET LFN=y' for some of the commands,
-especially the compilation commands. It might be more convenient to
-unpack the Emacs distribution with djtar, which comes with djgpp;
-djtar truncates file names to 8.3 naming as it extracts files, even if
-the system allows long file names, and this ensures that build
-procedures designed for 8.3 file names still work. Use as in `djtar x
-foo.tar' or `djtar x foo.tgz'.

-Some users report that running Emacs 19.29 requires dpmi memory
-management. We do not know why this is so, since 19.28 did not need
-it. If we find out what change introduced this requirement, we may
-try to eliminate it. ("May" because perhaps djgpp version 2's
-improved dpmi handling means this is no longer a problem.)
-
-It is possible that this problem happens only when there is not enough
-physical memory on the machine.
-
-You can find out if you have a dpmi host by running go32 (part of
-djgpp) without arguments; it will tell you if it uses dpmi memory.
-For more information about dpmi memory, consult the djgpp FAQ.

+(also known as djgpp), GNU Make, rm, mv, and sed. See the remarks in
+config.bat for more information about locations and versions. The
+file etc/FAQ includes pointers to Internet sites where you can find
+the necessary utilities; search for "MS-DOS". The configuration step
+(see below) will test for these utilities and will refuse to continue
+if any of them isn't found.
+
+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
+unpack the distribution and compile it. If you intend to compile with
+DJGPP v2.0 or later, and long file names support is enabled (LFN=y in
+the environment), you need to unpack Emacs distribution in a way that
+doesn't truncate the original long filenames to the DOS 8.3 namespace;
+the easiest way to do this is to use djtar program which comes with
+DJGPP, since it will note the LFN setting and behave accordingly.
+DJGPP v1 doesn't support long filenames, so you must unpack Emacs with
+a program that truncates the filenames to 8.3 naming as it extracts
+files; again, using djtar after setting LFN=n is the recommended way.
+You can build Emacs with LFN=n even if you use DJGPP v2, if some of
+your tools don't support long file names: just ensure that LFN is set
+to `n' during both unpacking and compiling.
+
+(By the time you read this, you have already unpacked the Emacs
+distribution, but if the explanations above imply that you should have
+done it differently, it's safer to delete the directory tree created
+by the unpacking program and unpack Emacs again, than to risk running
+into problems during the build process.)
+
+It is important to understand that the runtime support of long file
+names by the Emacs binary is NOT affected by the LFN setting during
+compilation; Emacs compiled with DJGPP v2.0 or later will always
+support long file names on Windows 95 no matter what was the setting
+of LFN at compile time. However, if you compiled with LFN disabled
+and want to enable LFN support after Emacs was already built, you need
+to make sure that the support files in the lisp, etc and info
+directories are called by their original long names as found in the
+distribution. You can do this either by renaming the files manually,
+or by extracting them from the original distribution archive with
+djtar after you set LFN=y in the environment.
+
+To unpack Emacs with djtar, type this command:
+
+ djtar -x emacs.tgz
+
+(This assumes that the Emacs distribution is called `emacs.tgz' on
+your system.)
+
+If you need to type international characters, you will need to unpack
+the Leim distribution (see the description near the beginning of this
+file). You unpack it from the same directory where you unpacked
+Emacs. To unpack Leim with djtar, assuming the Leim distribution is
+called `leim.tgz', type this command:
+
+ djtar -x leim.tgz
+
+If you want to print international characters, install the intlfonts
+distribution. For this, create a directory called `fonts' under the
+Emacs top-level directory (usually called `emacs-XX.YY') created by
+unpacking emacs.tgz, chdir into the directory emacs-XX.YY/fonts, and
+type this:
+
+ djtar -x intlfonts.tgz
+
+When unpacking is done, a directory called `emacs-XX.YY' will be
+created, where XX.YY is the Emacs version. To build and install
+Emacs, chdir to that directory and type these commands:
