I'd like to suggest that if 32 bit support is absolutely criticial for a 'port' that this be hidden under linux or osf1 compatibility mode. I'd really like to avoid seeing 'native' alpha-FreeBSD have to deal with this stuff. > > Rolf Neugebauer writes: > > > > taso actually is a linker option, ie independent of the compiler. > > Ah, yes.
