Why don't you pull out 4 bytes and assemble them manually? Three
shifts, logical ors and fromIntegrals aren't that much of a burden after

defined. Surprisingly, it is very difficult to see (it was a revelation for me
too). Perhaps the reason is that people get used to the mess in C
networking code.
