That's absolutely true.  I would mention, however, that in ancient 
times, I built and ran paranoia with a couple of different softfloat 
libraries, and was able to make it work with them.  If people care about 
softfloat (and I think they should), this should probably be 
investigated.  Easy for me to say, though... ;o)
