The standard only allows reading a value as the type it was written with or as char, and an access as char is only good for copying. If a char access used different bit order, that would be OK according to the standard because you couldn't tell unless you violated the standard.
It seems every compiler will tolerate a memcpy for type punning, even though this isn't required.
