etags structures tagging problem

[J.C. Wren]

   etags 21.3 (and perhaps other versions, I don't know) does not 
correctly ignore __attribute__ tags on structures. 

       typedef struct cacheLRUEntry_s
       {
         U16 next;
         U16 prev;
       }
       __attribute__ ((packed)) cacheLRUEntry_t;

   This results in the following tags file entry:

       typedef struct cacheLRUEntry_s^?cacheLRUEntry_s^A222,6076
       __attribute__ ((packed)^?packed^A227,6135

   Otherwise, it works great.  Thanks,
