A good compiler (and I've worked with at least one that could) would know the machine's endianness and could optimize away that sequence of selections, shifts and ors when it isn't needed.

Ok, but the performance penalty is then at compile time...

Lots of downvotes... Do you disagree? If so, why? Or do you think it is insignificant?

I've sat and watch C++ compile for 5 hours... Compile time performance is important too!
