Emacs will autolaunch a D-Bus session bus, when the environment
variable DISPLAY is set, but no session bus is running. This might be
inconvenient for Emacs when running as daemon or running via a remote
-ssh connection. In order to suppress D-Bus at all, configure Emacs
-with the options `--without-dbus --without-gconf --without-gsettings'.

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
Use --without-sound to disable sound support.
+Use --without-all if you want to build a small executable with the minimal
+dependencies on external libraries, at the cost of disabling most of the

+dependencies. So if you want to build a small executable with very basic
+X support, use --without-all --with-x-toolkit=no. For the smallest possible
+executable without X, use --without-all --without-x. If you want to build
+with just a few features enabled, you can combine --without-all with
+--with-FEATURE. For example, you can use --without-all --with-dbus
+to build with DBus support and nothing more.

Use --with-wide-int to implement Emacs values with the type 'long long',
even on hosts where a narrower type would do. With this option, on a
typical 32-bit host, Emacs integers have 62 bits instead of 30.

of editing in appropriate substitutions for the @...@ constructs.
