Not necessarily _need_ - we're just trying to implement all of the TR1
functions for which quantity argument make sense. That means that
we don't have to worry about the special functions, but do have to
worry about the ones mentioned here...
Even just wrapping the platform-dependent parts in a boost function
would be fine, AFAICS...

From my standpoint, it would strengthen the fp utils proposal if it was
relatively comprehensive - I'd be happy to test these out if that
