I'll check that. It might be that it knows how to avoid using the
FPU trap - but still not how to handle it. AD@ thinks that our fputrap()
code in the kernel is fishy, if I understood correctly. (I'd have committed
a fix a while now, but couldn't make more than _detecting_ the fpu in the
autoconf stage work.)
