Ah yes, sorry. I don't know anything about Mandriva. I really don't know why anyone would want to use -m64 on a 64-bit host. 64-bit is going to be the default anyway. I have no idea why you'd get an error from -m64, though. Someone who knows Mandriva may know the answers to these questions. Andrew.
