GCC 3.2 is well-known to generate bad code on some platforms, or to fail, with "internal compiler error" messages, when -march is used. That is why it's off by default. As Giorgos points out, there are knobs to turn it back on; if you do, however, it is at your own risk, since there are known to be problems. And before you ask: if we knew exactly what the problems were, we would fix them, instead of avoiding them. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
