    ada: Remove unnecessary special handling
    
    This patch removes a special exemption in Enter_Name. That exemption was
    preceded by a comment which described what situations it was supposed to
    be required for, but it was unnecessary even in those situations.
    
    gcc/ada/ChangeLog:
    
            * sem_util.adb (Enter_Name): Remove special handling.
