+Summary: explicit casting doesn't work on child classes.
+
+I have a class "A" which has the explicit casting operator overloaded to
+allow it to be casted to a class "X".  I also have a class "Y" derived from
+"X", but the compiler won't allow me to cast from "A" to "Y", although it
+works for "A" to "X".
+
+Attached is a test program that shows the behavior.  Works with csc, not
+with mcs.
