By my reading at least ppc, mips and sparc allow the default ABI to be changed via --with-float, but none of them have a separate target triplet for this purpose. > > It's worth noting that a while ago we made the deliberate decision to > > start ignoring the cpu field.

It does not. Part of the problem here is whether you want to default to the system you're running on, or the hardware you're running on. Unfortunately config.guess returns the latter, so obeying the cpu name effectively makes us default to --with-arch=native. Paul
