 = Naming
 
 * We've adopted the convention that internal AC_SUBSTs should be
-  named with a leading `_am_', and internally generated targets should
-  be named with a leading `_am-'.  This convention is very new
+  named with a leading `am__', and internally generated targets should
+  be named with a leading `am--'.  This convention is very new
   (as of Feb 7 2001) and so it isn't yet universally used.  But all
   new code should use it.
 
+  We used to use `_am_' as the prefix for an internal AC_SUBST.
+  However, it turns out that NEWS-OS 4.2R complains if a Makefile
+  variable begins with `_'.  Yay for them.  I changed the target
+  naming convention just to be safe.
