Fix the examples.
There are reasons why building for deterministic floating point might be
worth the performance cost, but examples relying upon 80-bit intermediate
precision isn't such a reason, IMHO.
Can you identify the examples in question? Is it just a case of performing
approximate-equality comparisons with too low a tolerance?
