Generate code for a little-endian word order but a big-endian byte order. If for some reason you are on Windows (#ifdef _WIN32) and big-endian simply reverse the data structures when you load from disk and just always save in little-endian format which is much more common. When you view the stored bytes as words, dwords, etc, they are always displayed with the most significant byte first. For this reason, we normally cross-compile most applications. Bit ordering inside bytes is generally only an issue when you're doing bit-by-bit I/O for instance when reading a stream of data sent over a serial line. In addition to the normal big (be) and little endian (le), rwmem supports "swapped" modification for endianness (bes and les).
