--fatal-type-errors is dartc specific. 

I think we want to add --enable_type_errors for the VM and frog.  And probable
we need to  actually instantiate myClass for the VM to analyze myClass.

 
-#library("Prefix14NegativeTest.dart");
+#library("Prefix21NegativeTest.dart");
 #import("library12.dart", prefix:"lib12");
 
 class myClass {
-  myClass(lib12.Library13 this.fld);
-  lib12.Library13 fld;
+  myClass(lib12.Library13 p) { // static type warning
+  }
 }
 
 main() {
 }
