    Fix EOF check in kadm5.acl line processing
    
    On platforms where the char type is unsigned, the check for EOF (which
    is negative) will always fail, leaving a 255 byte at the end of the
    line.  This can cause a syntax error, in turn causing the contents of
    kadm5.acl to be ignored.  Fix this bug by removing the cast on EOF.
