Ports are working with -02 -pipe -march=pentiumpro here, but there has been a problem with buildworld. Fatal compiler errors, sometimes a system seizure, panic, or spontaneous reboot. No problem building the kernel with those flags, last night tried using just -O -pipe for buildworld and seized. Fresh source install of RC3 and cvsup to RELENG_4 building now. One more try before trying with 4.0R. Was thinking an elusive hardware problem, which is not entirely ruled out, but maybe there is an issue with the compiler. Also seem to have worse problems with softupdates enabled on either the src or /usr/obj directory, but /usr doesn't seem to matter. Not related most likely, but am beginning to wonder about many things.
