    ada: Compiler accepts illegal assignment to reference type target.
    
    An assignment statement whose LHS is of a reference type is never legal. If
    no other legality rule is violated, then it is ambiguous. In some cases this
    ambiguity was not correctly detected.

            * sem_ch5.adb (Analyze_Assignment): Delete code that was
            incorrectly implementing a preference rule.
