page stated, thus BSD ar(1) option -q, which was implemented based on the GNU ar manual page, turns out to be incompatible with GNU ar -q. This change will make BSD ar(1) -q a *REAL* GNU ar -q: 1. It will update symbol table. (same as unfixed version) 2. It will NOT compare new members spcified in the command line args with existing members, instead, append them directly.
