Looking at further failures, it looks like 32-bit machines in general
get that result.  Might be just a cost estimation difference.

Also, some of the windows machines are folding "sqrt(2)" to a different
constant than is hard-wired into the expected-result file.  That's
slightly annoying because it calls into question whether we can ship
floating-point computations to the far end at all :-(.
