Use --without-sound to disable sound support.
Use --disable-features if you want to build a small executable with
the minimal dependencies on external libraries, at the cost
of disabling most of the features that are normally enabled by default.
Using --disable-features is equivalent to: --without-sound --without-dbus
--without-libotf --without-selinux --without-xft --without-gsettings
--without-gnutls --without-rsvg --without-xml2 --without-gconf
--without-imagemagick --without-m17n-flt --without-jpeg --without-tiff
--without-gif --without-png --without-gpm. Note that --disable-features
leaves X support enabled, and using the GTK2 or GTK3 toolkit creates a lot
of library dependencies. So if you want to build a small executable with
very basic X support, use --disable-features --with-x-toolkit=no.
For the smallest possible executable without X, use --disable-features
--without-x.

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
