    Microsoft C 6.0 accepts:

struct	master_log_entry
   {
    struct  log_entry	le;
    union
       {
        struct	gas_log_entry       gle;
        struct  status_log_entry    sle;
        struct  valve_log_entry     vle;
        struct  heat_log_entry      hle;
        struct  tool_log_entry      tle;
        struct  alarm_log_entry     ale;
       };
   };

struct master_log_entry	mle;


    then accepts references like:

	mle.gle.<reference to inside of gas_log_entry struct>

    and:

	&mle.gle


    without a complaint.  Am I just lucky?  gcc takes the definitions
(-ansi) but will not compile the code (i.e. `structure has no member named
"gle"').

    I really like being able to do that.  Anybody got the "Truth"?
