For the reason I wrote: > otherwise you run the risk of never > testing code outside the branch your dev machine(s) match. Imagine you compile and test your code on a big endian machine 99% of the time. Imagine you make a mistake in the little-endian branch. With the cpp approach, the compiler won't see the buggy code. With the other approach, it will, and may catch the mistake.
