`--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.

You can build Emacs for several different machine types from a single
source directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. Make separate
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:
(This assumes that the Emacs distribution is called `emacs.tgz' on
your system.) There are a few files in the archive whose names
-collide with other files under the 8.3 DOS naming. If you have set
-LFN=n, djtar will ask you to supply alternate names for these files;
-you can just press `Enter' when this happens (which makes djtar skip
-these files) because they aren't required for MS-DOS.

When unpacking is done, a directory called `emacs-XX.YY' will be
created, where XX.YY is the Emacs version. To build and install
MSDOG is a not a multitasking operating system, so Emacs features such
as asynchronous subprocesses that depend on multitasking will not
work. Synchronous subprocesses do work.
