Description
       Auxiliary entries are unions with a fixed length of four bytes per entry.  Much information is packed within the auxiliaries.  Rather  than
       have the compiler front-ends handle each type of auxiliary entry directly, the following set of routines provide a high-level scalar inter-
       face to the auxiliaries:

       st_auxbtadd	   Adds a type information record (TIR) to the auxiliaries.  It sets the basic type (bt) to the  argument  and	all  other
			   fields to zero. The index to this auxiliary entry is returned.

       st_auxbtsize	   Sets the bit in the TIR, pointed to by the iaux argument.  This argument says the basic type is a bit field and adds an
			   auxiliary with its width in bits.

       st_auxisymadd	   Adds an index into the symbol table (or any other scalar) to the auxiliaries.  It sets the value to the  argument  that
			   will occupy all four bytes. The index to this auxiliary entry is returned.

       st_auxrndxadd	   Adds  a relative index, RNDXR, to the auxiliaries.  It sets the rfd and index to their respective arguments.  The index
			   to this auxiliary entry is returned.

       st_auxrndxadd_idn   Works the same as st_auxrndxadd except that RNDXR is referenced by an index into the dense number table.

       st_iaux_copyty	   Copies the type from the specified file (ifd) for the specified symbol into the auxiliary table for the  current  file.
			   It returns the index to the new aux.

       st_shifttq	   Shifts  in the specified type qualifier, tq (see sym.h), into the auxiliary entry TIR, which is specified by the `iaux'
			   index into the current file. The current type qualifiers shift up one tq so that the first tq (tq0) is free for the new
			   entry.

       st_addtq 	   Adds a type qualifier in the highest or most significant non-tqNil type qualifier.

       st_tqhigh_iaux	   Returns the most significant type qualifier given an index into the files aux table.

       st_changeaux	   Changes the iauxth aux in the current file's auxiliary table to aux.

       st_changeauxrndx    Converts the relative index (RNDXR) auxiliary, which is specified by iaux, to the specified arguments.
