+// 1. there is an annoying warning.
+// singleton.C:26: warning: `class singleton' only defines private constructors and has no friends
+// egcs fails to see that there is a public static accessor function.
+// 2. the program crashes, because apparently the static variable s in
+// singleton::instance() is considered constructed although the ctor
+// exited via an exception. (crash changed to nonzero return here)
