 * There are known binary incompatibilities between Xaw, Xaw3d, neXtaw,
 XawM and the few other derivatives of Xaw.  So when you compile with
 one of these, it may not work to dynamically link with another one.
-If you try it and it does not work, try rebuilding Emacs with the
-toolkit version you actually want to use.
+For example, strange problems, such as Emacs exiting when you type
+"C-x 1", were reported when Emacs compiled with Xaw3d and libXaw was
+used with neXtaw at run time.
+
+The solution is to rebuild Emacs with the toolkit version you actually
+want to use, or set LD_PRELOAD to preload the same toolkit version you
+built Emacs with.
