 Warns that a non-void function is being called as a task, and hence the
-return value is being ignored. This warning is required by IEEE.
+return value is being ignored.
+
+This warning is required by IEEE. The portable way to suppress this warning
+(in SystemVerilog) is to use a void cast, e.g.
+
+    void'(function_being_called_as_task());
 
 Ignoring this warning will only suppress the lint check, it will simulate
 correctly.
