Me neither. _Be_mused, baffled.

I don't know whether it's any more than numerical political
correctness. I've been flamed several times for querying claims
apropos both x86 and Alpha that LAPACK (specifically, possibly other
things) requires strict IEEE double behaviour. The flamers produced
no evidence, but I guess it might still be so and that I ought to ask
the LA pack themselves.
