For reference, here is the final version of my code.  Note that I have
re-arranged the tests so the test for equality comes first - this

performance gain whilst slight is measurable.


There is no need for bswap when testing for equality. The expression
(bswap(*ua) == bswap(*ub)) gives the same result as (*ua == *ub).
