Who told you such a change is in the works? I no of no change and not reason to change it. (Note that there are at least 2 32 bit versions and they will remain so for efficiency reasons; the one type unsupported by older CPUs is used because it is more efficient) Casper _______________________________________________ opensolaris-code mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
