 * The rest of this file deals the symdef file. This file contains a hash table

 *	the ran_off field is non-zero, then the element refers to a defined
 *	external in one of the member files.
 *
 * The symdef file name is always prefixed by SYMPREF. The IHASHSEXth
 *	character in the name determines the sex of the hash table and
 *	the ITARGETSEXth character determines the target sex of the
 *	members -- no  symdef file will be created if there are member 
 *	with conflicting target sexes (see the -s flag in ar.c).
 *
 * In addition, if an archive is modified with ar, the IOUTOFDATEth character
 *	in the name of the symdef file will be set to OUTOFDATE. The other times
 *	it will be set to '_'
 *
 * Notes:
 *	1) Mips archives use the "PORTAR" or portable archive format.
 *	2) You must include sex.h before ar.h if you use the symdef macros.
