Should I be able to drop any of these, at this > point? You can remove the --with-cpu; the default on AIX4.3 is 604e, which should work fine. I don't think you can yet remove the --disable-powercpu since I didn't touch the multilib code (I completely missed it, and wow it's a nice little maze all of itself). I have no idea about --disable-aix64. Try and see :-)
