+  No special procedures should be needed to build a 64-bit Emacs.  To
+  build a 32-bit Emacs, first ensure that the necessary 32-bit system
+  libraries and include files are installed.  Then use:
+
+    env CC="gcc -m32" ./configure --build=i386-linux-gnu \
+      --x-libraries=/usr/X11R6/lib
+
+  (using the location of the 32-bit X libraries on your system).
