Names related to structures, unions, and enumerations

The auxiliary table entries for structure, union, and enumeration symbols have the format shown in ``Entries for structures, unions, and enumerations'':

Entries for structures, unions, and enumerations

Bytes	Declaration	Name	Description
0-3	long int	x_tagndx	tag index
4-5	-	-	unused (filled with zeroes)
6-7	unsigned short	x_size	size of the structure, union, or enumeration
8-17	-	-	unused (filled with zeroes)

Aggregates defined by typedef may or may not have auxiliary table entries. For example,

   typedef struct people STUDENT;

   struct people
   {
          char name[20];
          long id;
   };

   typedef struct people EMPLOYEE;

The symbol EMPLOYEE has an auxiliary table entry in the symbol table, but symbol STUDENT will not because it is a forward reference to a structure.
