Well check this man page http://gcc.gnu.org/onlinedocs/gcc-3.4.4/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options it will have everything, I hope, you need to know. Native 32-bit mode? All AMD Athlon64/Sempron/Opteron CPUs support 32-bit mode quite natively. As for Semprons - there are some called 64-bit enabled. I have one of those. Thanks very much for the link. I put some knobs into my make.conf file - but it's not just that easy, no. Some apps do not like the newer knobs like -msse3, so I have yet to come up with a better solution than to edit make.conf before each build. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
