On the other hand, is there any point in supporting it? This does seem to be a case for which it does seem like having the extra VM space (KVM+TCG) and the extra register size (TCG) is extremely helpful. I'd be just as happy to adjust the configury to actively prevent compilation in 31-bit mode, rather than pretend it might work and never bother to test it... r~
